FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with metabolites is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about metabolites, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to metabolites, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on metabolites. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to metabolites, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on metabolites. The Editors

CHAPTER 1. STUDIES ON METABOLITES Overview In this chapter, we will show you how to locate peer-reviewed references and studies on metabolites.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and metabolites, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “metabolites” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
Decreased Lumbar Cerebrospinal Fluid Levels of Monoamine Metabolites in Vascular Dementia Source: International Psychogeriatrics. 8(3): 425-436. 1996. Summary: This journal article describes a study that investigated lumbar cerebrospinal fluid (CSF) levels of monoamine metabolites in 56 patients with vascular dementia (VAD). The patients, aged 56 to 89 years, were from the neuropsychiatric ward of Molndal Hospital, University of Goteborg, Sweden. Using a standardized protocol, levels of the monoamine metabolites 5-hydroxyindoleacetic acid (5-HIAA), homovanillic acid (HVA), and 4-hydroxy-3-methoxyphenylglycol (HMPG) were measured in the patients with VAD, and 57 healthy controls, aged 51 to 85 years. The VAD group had significantly lower HVA, 5-HIAA, and HMPG concentrations than the control group. However, there was wide variation in values in both groups and

considerable overlap between groups. The monoamine metabolite levels were not associated with degree of dementia in the patients with VAD. The authors conclude that the low CSF levels of monoamine metabolites in patients with VAD do not appear to be disease specific, but may be attributable to subcortical white matter changes or to a decreased production of monoamines, which are dependent on oxygen for their synthesis. 1 figure, 4 tables, 44 references.
Federally Funded Research on Metabolites The U.S. Government supports a variety of research studies relating to metabolites. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to metabolites. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore metabolites. The following is typical of the type of information found when searching the CRISP database for metabolites: •
Project Title: ACYLCOA PHARMACOKINETICS

BINDING,
Principal Investigator & Institution: Benet, Leslie Z.; Professor; Biopharmaceutical Sciences; University of California San Francisco 3333 California Street, Suite 315 San Francisco, Ca 941430962 Timing: Fiscal Year 2002; Project Start 01-APR-1986; Project End 31-MAR-2004 Summary: The overall goal of the research described in this renewal is to investigate the hypothesis that acyl-CoA thioester metabolites of carboxylic acid-containing drugs are reactive acylating species that, in addition to, but possibly more important than, reactive acyl glucuronides, contribute to the covalent binding of acidic drugs to proteins and which may be responsible for, among other toxicities, untoward allergic side-effects. This hypothesis will be focused on by a range of in vitro and in vivo studies, as directed by the following specific aims: 1) To evaluate the chemical reactivity of acyl-CoA thioester derivatives with biological nucleophiles and compare such reactivity with that of their respective acyl glucuronides; 2) To evaluate the effect of enzyme inducers and inhibitors, with respect to acyl glucuronidation and acyl-CoA formation, on the covalent binding of selected carboxylic acids to protein; 3) To quantitatively determine and compare the levels of drug-protein acylation, acyl glucuronidation and acyl-CoA formation of selected carboxylic acid drugs in vivo in selected tissues; 4) To develop improved methodology for the analysis of acyl-CoA thioester derivatives from biological samples; 5) To determine the effect of alpha-fluoro-substitution of carboxylic 2

acid drugs on xenobiotic acyl-CoA formation and protein acylation; 6) To assess the enantioselectivity of covalent binding of chiral NSAIDs to protein and their metabolism to reactive acylating derivatives in vivo and in vitro, 7) To identify the hepatic protein targets for reactive metabolites of diclofenac, resulting from either glucuronide or CoAthioester intermediates, using 2D-PAGE and mass spectrometry; 8) To investigate the role of the enzymes of fatty acylation on the selective acylation of cellular proteins by acidic drugs through their acyl-CoA thioester derivatives; 9) To determine if drugprotein conjugates formed by the reaction of xenobiotic-acyl-CoA thioester derivatives with protein are antigenic. This application proposes studies designed to: (a) characterize the chemical reactivity of acyl-CoA thioester metabolites of a number of acidic drugs, (b) compare this reactivity with corresponding acyl glucuronide metabolites, (c) elucidate the mechanisms by which protein acylation may occur for carboxylic acid-containing drugs through the CoA thioester pathway, as well as define the chemical structure of these products and (d) evaluate the immunotoxic potential of these thioester metabolites. In addition, since activation of endogenous fatty acids to their corresponding high-energy acyl-CoA thioester derivatives is an important enzymatic step required prior to the utilization of fatty acids for many cellular reactions, the findings of this work should provide important insights beyond immunotoxicity questions.

Project Title: AMINE N-OXYGENATION BY FMO3 AND FMO4 Principal Investigator & Institution: Cashman, John R.; Senior Scientist; Human Biomolecular Research Institute 5310 Eastgate Mall San Diego, Ca 921212804 Timing: Fiscal Year 2002; Project Start 15-APR-2002; Project End 31-MAR-2006 Summary: (provided by applicant): Variation in neurotransmitter transporters, receptors and abnormal levels of neurotransmitters potentially are involved in neurological diseases including schizophrenia, bipolar affective disorder, autism, affective disorder, late onset Alzheimer's disease, Parkinson's disease and others. Fundamental information characterizing human neurotransmitter metabolism associated with neurodegenerative diseases could provide new approaches to understanding the pathology and developing new therapeutics. Our central hypothesis is that lack of detoxication of endogenous or xenobiotic amines underlies the pathological condition of some CNS diseases. The human flavin-containing monooxygenase (FMO) is one of the major human enzyme systems that contribute to the detoxication of endogenous, environmental and dietary nitrogen-containing substances. The overall goal of our work is to understand the details of FMO-mediated N-oxygenation of amines and hydroxylamines. Accumulation of hydroxylamines in the CNS may lead to cytotoxicity or apoptosis. To test this, fundamental information about human brain FMO N-oxygenation is required. The overall goal will be accomplished by addressing five Specific Aims including: Aim 1: cDNA-express the major forms of human brain FMO; Aim 2: Chemically synthesize amine metabolites of human brain FMO; Aim 3: Determine the kinetics and mechanism of human brain FMO amine N-oxygenation; Aim 4: Test the effects of human brain FMO amine metabolites on neuronal cell function including cytotoxicity and apoptosis, and Aim 5: Investigate the mechanism of amine metabolites on human neurotransmitter function. The significance is that fundamental biochemical information will result in new insight about the way endogenous and xenobiotic and dietary amines are metabolized in human brain. Such fundamental information will be useful in the development of safer drugs, the prevention of adverse drug reactions and the protection of humans from disease.

Project Title: ANALYTICAL CHEMISTRY CORE Principal Investigator & Institution: Wishnok, John S.; Senior Research Scientist; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 07-APR-1993; Project End 31-MAY-2007 Summary: (provided by applicant): This Core operates as a service, a developmental laboratory, and a resource for the Program Project. Both the overall objectives and the specific aims of the Core laboratories follow primarily from those of the individual projects; e.g., development of methods for identification or quantitation of carcinogennucleic acid adducts, carcinogen-protein adducts, and carcinogen metabolites and/or their conjugates. This includes continued evaluation of capillary HPLC-LIF for quantitation of protein or DNA damage and continued development of capillary HPLC and nanoelectrospray/microelectrospray tandem MS techniques to characterize and quantitate modified proteins or DNA. Development or adaptation of methods to quantitate DNA or protein adducts or urinary levels of PhIP or 2-amino-3,8dimethylimidazo-[4,5-f]quinoxaline (MeIQx) or their metabolites during previous funding periods, for example, was in direct response to the needs of epidemiological studies that evolved into Project 1 in this proposal. Many of the methods listed below were adapted or developed by the Core in this context and some methods, such as quantitation of aromatic amine-hemoglobin adducts by NICI GC-MS have in some cases become the methods of choice for other laboratories that carry out related investigations. The specific aims of the various research projects involve quantitation in urine, physiological fluids or tissue, of DNA and protein adducts of several carcinogens including aflatoxin and aromatic amines and related compounds (e.g., alkylated anilines) and quantitation of urinary excretion of the food-related carcinogen, PhIP, and its metabolites or conjugates. Literature methods are often based on pure or in vitro samples, so methods are developed for the isolation or concentration of low levels of these compounds in complex biological mixtures using, for example, solid-phase extractions or affinity chromatography. Where necessary, for example with tandem MS methods for analyses of modified oligonucleotides, the developmental work is done in the Core laboratories. Specific objectives for additional analyses or techniques include: (1) development and applications of ultrasensitive MS methods for nucleobase and deoxyribonucleoside adducts; (2) development and applications of HPLC-LIF methods for quantitation of derivatized adducts; and (3) transfer of HPLC-LIF technology to the Johns Hopkins University (Project 1 and Core).

Substance P is an important neuropeptide that has been shown to be involved pain perception, inflammation, and a number of disease states including depression and Alzheimer's. Substance P is released in both the brain and peripheral tissue. It is metabolized by a number of different

peptidase enzymes in the brain. Many of its metabolites have also been shown to be neurochemically and/or physiologically active. Recently, we have shown that SP can be transported across the blood-brain barrier (BBB) using an in vitro model of the BBB. Substance P was shown to undergo enzymatic degradation at this barrier to smaller peptides that can also permeate the BBB. In this proposal, methods for monitoring the release, transport, and metabolism of substance P in both central and peripheral tissue will be developed. These methods will then be used to investigate the role of the bloodbrain barrier in the distribution of substance P and its metabolites between the brain and peripheral tissue in healthy and diseased animals. In addition, the development of separation-based sensors based on microdialysis and microchip CEEC for measuring the activity of nitric oxide synthase and the production of NO will be explored. Nitric oxide is known to change the permeability of the blood-brain barrier. The effect of substance P on the expression of the inducible form of nitric oxide synthase (INOS) and the release of NO at this barrier will also be investigated.

Project Title: INTERACTIONS
ANGIOTENSINS,
PROSTAGLANDINS-ADRENERGIC
Principal Investigator & Institution: Malik, Kafait U.; Professor; Pharmacology; University of Tennessee Health Sci Ctr Memphis, Tn 38163 Timing: Fiscal Year 2002; Project Start 01-SEP-1977; Project End 31-AUG-2007 Summary: (provided by the applicant): Our long-term goal is to investigate the mechanism of interaction of the adrenergic nervous system, angiotensin II (Ang II) and eicosanoids in the regulation of cardiovascular function and in the development of hypertension. Over the past grant period, we have shown that norepinephrine (NE)and Ang II stimulate calcium/calmodulin dependent protein kinase II (CaMKII) phosphorylate cytosolic phospholipase A2 (cPLA2) and release AA in vascular smooth muscle cells (VSMC); AA metabolltes formed via cytochrome P450 (CYP45O) and lipoxygenase (LO) activate phosphoilpase D (PLD), amplify cPLA2 activity and contribute to VSMC hyperplasia and/or hypertropby and hypertension. This proposal is an extension of these studies and will test the hypotheses that: 1) Phosphorylation of cPLA2 at Ser-515 by CaMKII is responsible for its activation, translocation to the nuclear envelope and AA release in response to NE- and Ang II. 2) Translocation of cPLA2 to the nuclear envelope is dependent upon vimentin phosphorylation and actin filament organization, which is maintained by phosphorylation of heat shock protein 27 (HSP27) by ERK1/2. 3) AA metabolites derived via CYP45O and LO by transactivating epidermal growth factor receptor (EGFR) and/or NAD(P)H oxidase, activate ERK1/2, which causes further phosphorylation of cPLA2 at Ser505/727, and of PLD2 at a Tyrresidue(s), and promotes VSMC proliferation and/or hypertrophy. The specific alms of the proposal are: I. Signaling Mechanisms Involved in NE-induced cPLA2 and PLD Activation and their Functional Significance. Aim 1. To determine if NE-stimulated CaMKII, by phosphorylating cPLA2 on Ser-515, promotes AA release, Ras/ERK1/2 and PLD activation and VSMC proliferation. Aim 2. To investigate the contribution of CaMKII, Ras-ERK1/2, actin, vimentin and heat shock protein (HSP27) to NE-induced cPLA2 translocation to the nuclear envelope and the underlying mechanism involved Aim 3. To examine the contribution of epidermal growth factor receptor (EGFR) transactivation and NAD(P)H oxidase to AA metabolite-induced activation of RasERK1/2 and PLD2, amplification of cPLA2 activity and VSMC proliferation in response to NE. Aim 4. To elucidate the mechanism of PLD activation by tyrosine phosphorylation caused by cPLA2 derived AA metabolites via ERK1/2 and p38 MAPK

in response to NE. II. Signaling Mechanisms Involved in Ang II-Induced cPLA2 and PLD Activation and their Functional Significance. We will also investigate the effects of Ang II on the above signaling mechanisms in VSMC using an approach similar to that described for NE. We will include Ang II and NE in the same protocols. These studies should further our understanding of the cellular mechanisms involved in NE-and Ang II- induced cPLA2 activation and AA release and the mechanism by which AA metabolites cause PLD activation, amplification of cPLA2 activity and VSMC proliferation and hypertrophy.

Project Title: ANTINEOPLASTIC V LEUKEMOGENIC EPIPODOPHYLLOTOXIN EFFECTS Principal Investigator & Institution: Felix, Carolyn A.; Associate Professor; Children's Hospital of Philadelphia 34Th St and Civic Ctr Blvd Philadelphia, Pa 191044399 Timing: Fiscal Year 2003; Project Start 16-FEB-1999; Project End 31-JUL-2008 Summary: (provided by applicant): The objective of this work is to understand the nature of the DNA damage leading to MLL translocations in leukemias following anticancer treatment with DNA topoisomerase II inhibitors. The CYP3A4 promoter is polymorphic and CYP3A4 genotype confers susceptibility. CYP3A4 converts etoposide to etoposide catechol; the catechol is readily oxidized to a quinone. These metabolites are genotoxins. MLL joins with one of many partner genes to form the translocations. The genomic breakpoint junction sequences contain evidence of DNA damage and repair. Several genomic breakpoint junction sequences indicate precise or near-precise interchromosomal DNA recombinations, but the cloning of additional breakpoints is essential to discern the damage spectrum. Etoposide and its metabolites induce DNA topoisomerase II cleavage at the translocation breakpoints in MLL and in its partner genes in vitro. We propose that etoposide and its metabolites can stimulate a series of different DNA lesions, which are repaired to form the breakpoint junctions, and that the heterogeneity in genomic breakpoint junction sequences reflects heterogeneity in the damage and its resolution. The DNA lesions to be tested include the direct induction of DNA topoisomerase II cleavage by etoposide parent drug, induction of DNA topoisomerase II cleavage from DNA adduct formation by etoposide quinone or reactive oxygen species, replication fork collisions with DNA topoisomerase II covalent complexes and DNA topoisomerase II-independent damage. Aim 1 will examine the spectrum and quantify the relative importance of DNA adducts from etoposide metabolites in an MLL bcr DNA substrate using mass spectrometry. Aim 2 will investigate the induction of functional DNA topoisomerase II covalent complexes in MLL and in the genome by etoposide and etoposide metabolites in human CD34+ hematopoietic progenitor cells using DNA arrays. To answer whether, how often and to what degree precise recombinations, exonucleolytic nibbling, large deletions, insertions, inversions, duplications and nonhomologous end-joining have occurred in creation of the breakpoint junctions, Aim 3 will characterize the genomic sequences of both derivative chromosomes in the leukemias in patients. Solving the mechanism of leukemogenesis of the DNA topoisomerase II inhibitors is highly relevant to the targeted prevention of this usually fatal complication of anticancer treatment.

Project Title: APPROACHES TO CHARACTERIZATION OF ANTIINFECTIVE AGENTS Principal Investigator & Institution: Hamann, Mark T.; Associate Professor; Pharmacognosy; University of Mississippi P.O. Box 907 University, Ms 386770907 Timing: Fiscal Year 2002; Project Start 01-AUG-1998; Project End 31-JUL-2003 Summary: The primary focus of this project is the isolation and characterization of new chemotypes for the treatment of infectious diseases. This includes research involving the development of instrumentation for the rapid and thorough analysis of bioactive organic compounds in complex biological mixtures. Our goal is to integrate the most powerful tools available for the purification and structure determination of organic materials into a single system while being able to recover nearly 95 percent of the purified sample for biological evaluation. The most promising metabolites will be studied for structure-activity relationships (SAR) using semi-synthesis, microbial transformations and molecular modeling. Natural product research during the last few decades has yielded thousands of novel organic compounds from the marine environment. The bioassays guiding these isolations typically have been antimicrobial, antitumor, antiviral or antiinflammatory. Little has been done to explore the oceans for compounds with activity against HIV, AIDS OI, TB and other infectious diseases. Additionally, because of the limits associated with the conventional self-contained underwater breathing apparatus (SCUBA), the majority of the compounds characterized from the marine environment are the results of shallow water collections (-30m). Dr. Michael Boyd, of the Laboratory of Drug Discovery Research and Development at the National Cancer Institute indicates that mass screening has proved to be the most effective means of discovering entirely new chemotypes not even suspected to have relevant biochemical properties. The objective of this proposed research program is to collect and screen marine samples for possible treatments of HIV and AIDS OI from depths and locations in the ocean which have remained unexplored. The active component(s) of those extracts showing promising activity will be isolated using preparative and semi-preparative high pressure liquid chromatography (HPLC) interfaced with NMR and FTMS. The chemical structures of the biologically active secondary metabolites will be determined with the use of LC-NMR-FTMS and 2D NMR. Methods for providing sufficient quantities for in vivo testing via synthesis, semisynthesis or reisolation will be addressed for promising compounds. SAR studies will be conducted utilizing chemical and microbial transformations of biologically active secondary metabolites combined with molecular modeling studies.

Project Title: BENZENE METABOLITES AND HEMATOTOXICITY Principal Investigator & Institution: Monks, Terrence J.; Professor and Chair; Div/Pharmoacology & Toxicology; University of Texas Austin 101 E. 27Th/Po Box 7726 Austin, Tx 78712 Timing: Fiscal Year 2002; Project Start 01-JUN-2000; Project End 31-MAY-2005 Summary: (Adapted from applicant's abstract): Benzene, a major industrial chemical and environmental pollutant, causes a variety of hematological disorders in man, including aplastic anemia, myelodysplastic syndrome, and acute myelogenous leukemia. While it is clear that benzene must be metabolized to cause its acute hematotoxic effects, no single metabolite of benzene reproduces these effects in vivo. Coadministration of hydroquinone (HQ) and phenol (PHE), however, does lead to bone marrow suppression in rodents. A pharmacokinetic interaction between these two

benzene metabolites results in increased concentrations of both metabolites in bone marrow. Peroxidase and/or phenoxy-radical mediated oxidation of HQ then initiates redox cycling and formation of the reactive electrophile, 1,4-benzoquinone, which is considered the ultimate hematotoxic metabolite of benzene. However, 1,4benzoquinone readily undergoes glutathione (GSH) conjugation to form 2-(glutathion-Syl)hydroquinone, 2,5-bis-(glutathion-S-yl)hydroquinone, 2,6-bis-(glutathion-Syl)hydroquinone, and 2,3,5-tris-(glutathion-S-yl)hydroquinone. Preliminary data indicate that these GSH conjugates are present in the bone marrow of rats and mice following coadministration of hydroquinone and phenol. Moreover, the majority of HQGSH conjugates present in bone marrow are formed in situ and are metabolized to more reactive thiol conjugates via a previously unidentified mercapturic acid pathway. Because these quinol-thioether metabolites have enhanced capability to both redox cycle and arylate tissue macromolecules, we hypothesize that quinol-thioether metabolites contribute to benzene-mediated hematotoxicity and that the mechanism(s) likely involve the production of reactive oxygen species and/or interaction with proteins that specifically recognize GSH/cysteine and GSH/cysteine containing molecules. Such metabolite specific interactions interfere with growth- and differentiation-related signaling. We therefore propose to (i) assess the acute hematotoxicity of HQ-GSH conjugates in rodent hematopoietic tissue, (ii) determine changes in the production and/or function of hematopoietic growth factors in response to HQ-GSH conjugates, (iii) test the hypothesis that metabolite-induced changes in gamma-glutamyl transpeptidase activity (GGT), dipeptidase activity, cysteine transport, and GSH concentrations, precipitate sphingolipid turnover, the generation of ceramide and the induction of apoptosis, and (iv) test the hypothesis that specific proteins involved in the synthesis (GST), transport (GS-X pump), and metabolism (GGT, dipeptidases) of the peptidyl leukotrienes are targets of HQ-GSH conjugates and interfere with granulocytic cell differentiation. Because benzene reduces the number of myeloid stem cells in bone marrow and induces incomplete granulocytic differentiation, our studies will provide a comprehensive understanding of the mechanisms by which reactive polyphenolic metabolites of benzene cause perturbations in growth- and differentiation-related signaling and how such changes culminate in benzene-mediated hematotoxicity.

Project Title: BIOACTIVATION OF DIETARY PHENOLS BY HEMOPROTEINS Principal Investigator & Institution: Thompson, John A.; Professor; Pharmaceutical Sciences; University of Colorado Hlth Sciences Ctr P.O. Box 6508, Grants and Contracts Aurora, Co 800450508 Timing: Fiscal Year 2002; Project Start 30-SEP-1994; Project End 31-JUL-2003 Summary: The long-term goal of this research is to elucidate the underlying mechanisms by which phenolic compounds present in the human diet influence tumorigenesis. Ongoing studies demonstrates that the oxidative metabolism of alkylphenols by cytochromes P450 lead, in many cases, to the formation of quinoid products capable of covalent binding and/or free radical generation in cells. We now propose to extend this work to investigate the involvement of such reactive metabolites in tumor promotion utilizing the most thoroughly characterized model for probing mechanistic aspects of promotion in the lung. This system involves the enhancement of lung tumor development by chronic administration of the food additive butylated hydroxytoluene (BHT) to carcinogen-initiated mice. It has been demonstrated that metabolism of BHT in the target organ is necessary for promotion and it is known that BHT is converted to

11
reactive quinoid metabolites in lung. These findings lead to the hypothesis that promotion depends upon two successive P450 catalyzed oxidations to the ultimate promoting species, a strongly electrophilic quione methide which alkylates one or more critical proteins leading to a disruption of growth control mechanisms. The following specific aims are proposed: (1) Determine the role of metabolism in the differential responsiveness of promotion- sensitive (B+) and promotion-resistant (B-) mice to the lung tumor promoter BHT. Conversion of BHT to a quinone methide and other reactive metabolites, as well as the detoxification of reactive metabolites, will be examined in lung tissues and cells from B+ and B- mice. (2) Investigate alkylation targets of a BHTderived quinone methide in lung cells that directly or indirectly impair cell-cell signaling. Protein alkylation by a highly reactive quinone methide metabolite of BHT will be examined in cells isolated from the lungs of B= and B- mice, and in tumorigenic and non-tumorigenic cell lines derived from murine lung. Alkylation patterns will be compared by radiochemical and immunochemical methods and selected adducts identified by mass spectrometry and microsequencing. (3) Examine biochemical consequences and oxidative damage in lung cells exposed to reactive metabolites of BHT. Isolated cells from B+ and B- mice and cell lines will be treated with reactive quinoid metabolites of BHT to investigate cytotoxicity, oxidative damage, inhibition of mitochondrial function, and inhibition of enzymes involved in detoxification.

Project Title: BIOLOGICALLY ACTIVE MICROBIAL METABOLITES Principal Investigator & Institution: Floss, Heinz G.; Professor; Chemistry; University of Washington Grant & Contract Services Seattle, Wa 98105 Timing: Fiscal Year 2002; Project Start 01-DEC-1987; Project End 31-DEC-2003 Summary: The primary focus in the continuation of our studies on the biosynthesis of antibiotics and other microbial metabolites will be on three Actinomycete antibiotics which contain mC7N units of different biosynthetic origin. These are rifamycin, an antitubercular drug whose semisynthetic derivatives, like rifampicin, are widely used clinically, asukamycin, a member of a family of compounds which have shown, inter alia, inhibition of protein prenylation and of interleukin-1beta converting enzyme, and validamycin, a commercial agent against phytopathogenic fungi but also the precursor for the synthesis of the clinical antidiabetic drug, voglibose. In all three cases the object is to define the biosynthetic pathway and its genetic control, and to unravel key biochemical reaction mechanisms involved in these biosyntheses by a combination of molecular biological and biochemical approaches, and to lay the foundation for the generation of modified bioactive structures through genetic engineering. A secondary focus is on the elucidation, at the genetic, enzymatic and mechanistic level, of the mode of formation of the 2,6-dideoxyhexose moieties of the unusual macrolide antibiotic, chlorothricin, and of the formation and mode of attachment of the 2,6-dideoxy- and 2,3,6- trideoxyhexose moieties of the benzoisochromane quinone antibiotic, granaticin. These studies will help provide the knowledge base and the tools to modify the structures of various bioactive natural products by the attachment of different sugar moieties. Thirdly we will complete ongoing studies on the biosynthesis of phenazine antibiotics, the saphenamycins and esmeraldins, with the aim of identifying unequivocally the structure of the monomeric shikimate pathway derivative which undergoes dimerization to the general precursor, phenazine-1,6-dicarboxylic acid, and on the thiopeptide antibiotics, nosiheptide and thiostrepton, aimed at cloning the correct peptide synthases encoding their formation.

Project Title: BIOMARKERS OF AGING IN THE SERA METABOLOME Principal Investigator & Institution: Kristal, Bruce S.; Assistant Research Scientist; Winifred Masterson Burke Med Res Inst Medical Research Institute White Plains, Ny 10605 Timing: Fiscal Year 2004; Project Start 15-AUG-2004; Project End 31-JUL-2006 Summary: provided by applicant): The identification of valid, robust biomarkers of aging and age-related processes has been an elusive goal. Dietary restriction (DR, long term, low calorie diets) has established efficacy in increasing longevity and decreasing morbidity in rodents. We have now identified 93 components of the sera metabolome that define a DR serotype - i.e., a metabolic serotype or biomarker profile that reflects caloric intake. Megavariate pattern recognition analysis has identified metabolic profiles in both male and female rats that distinguish ad libitum fed and DR rats (100% accuracy in training sets, mean >90% in test sets). Profiles are robust across the lifespan (6,12,18,24, and 30 months). Profiles reflect duration of DR (fasted, 1, 2, 4, 8 weeks) and extent of restriction (10,20,30, 40% DR, r2 = 0.88 for N = 90). Profiles also distinguish long- and short-lived strains of mice, suggesting that at the profile, at least in part, reflects the physiological benefits of DR in addition to the decreased food intake. Most metabolites (>70%) cross species to humans, suggesting that the HPLC-based technique used identifies broadly conserved metabolites. We now propose to use our existing bioinformatics platform to reexamine our existing rat sera metabolomics data (>600 rats, -600,000 data-points) to identify biomarkers and metabolic profiles reflective of the aging process. This work extends our ongoing work into a new direction: a metabolome-based approach to aspects of aging. The work will be completed in the context of 4 focused Aims: Aim 1. To determine the extent to which previously identified biomarkers of DR are also biomarkers of aging Aim 2. To determine the extent to metabolites in major metabolic pathways (e.g., purines, tyrosine metabolites, tryptophan metabolites, antioxidants, neurotransmitters) are also biomarkers of aging Aim 3. To identify previously unstudied metabolites that are modulated by the aging process The markers studied in Aims 1-3 have complementary advantages for future studies: (a) likely correlation of biomarkers of aging and those of physiological deterioration captured by DR; (b) the broad literature on compounds in major pathways, and; (c) the potential to open new vistas with previously undefined markers Aim 4. To use the biomarkers above to build metabolic profiles of the aging process Profiles will be examined/generated using megavariate approaches available in the laboratory (e.g., 1 and 2-D clustering, heat maps, self-organizing maps, principal components analysis, partial least squares, partial least squares projection to latent structures discriminant analysis, ere).

These adolescents are exposed to pesticide spray (drift) and residues in the soil and on foliage. However, little scientific evidence is

available to determine acceptable levels of pesticide exposure in this vulnerable population. Pesticides are thought to pose a considerably higher biological risk to children than to adults, but little is known about the extent or magnitude of this vulnerability. The potential of neurotoxicity related to chronic low-dose pesticide exposure in children is a major public health concern. Also, there may be risk factors that influence the occupational exposures of youth agricultural workers, and the period of rapid development during adolescence may introduce added risk in areas such as DNA damage related to pesticide exposure. Our interdisciplinary research team will use a cross-sectional, repeated measures design to compare adolescent farmworkers to their adult counterparts and to non-agricultural referent groups in order to: 1) determine differences in exposure to agricultural chemicals with urinary biomarkers of pesticide metabolites, 2) examine the relationship between urinary pesticide metabolites and neurobehavioral performance, and 3) determine age-related differences in pesticideinduced markers of DNA damage and oxidative stress.

Project Title: BIOSENSORS FOR METABOLIC ENGINEERING Principal Investigator & Institution: Keasling, Jay D.; Chemical Engineering; University of California Berkeley Berkeley, Ca 947205940 Timing: Fiscal Year 2004; Project Start 01-FEB-2004; Project End 31-JAN-2007 Summary: (provided by applicant): The study of metabolism has made great strides elucidating the metabolic pathways that sustain life in the cell. This investigation has produced a complex map of metabolites and enzymes that describe the chemical transformations that are possible in an organism. With the sequencing of entire genomes it is possible to foresee the conclusion of this phase of study such that the function of each gene product encoded in a genome will be described and every metabolite will be cataloged. At that point, we will have a static view of the chemistry possible in an exquisitely dynamic organism. To gain insight into the dynamic structure of metabolism, new tools must be developed to measure transient levels of metabolites in a living cell. The research proposed here will develop tools for the real-time monitoring of intra-cellular metabolites in vivo using native and engineering biosensors founded on transcriptional regulators. Although the tools developed here will be of value for the study of metabolism in general, we will focus our research on the development of biosensors for the purpose of directing the evolution of metabolism. The identification of chemical compounds has traditionally relied on expensive and cumbersome analytical instruments that require considerable expertise to operate. The data generated by these machines must be interpreted by a trained scientist to accurately determine the presence or absence of a specific compound in a complex sample. Microorganisms face a similar problem as they must constantly sample their chemical environme nt to identify the most efficient source of carbon, nitrogen and other cellular building materials. Microbes accomplish this task through a multitude of biological sensing systems (biosensors) that determine which metabolic pathway should be expressed at any given time. Exploiting these sensor-actuator systems to detect target compounds will not only provide the tools for the next phase of metabolism study, but will also deliver methodology to direct the metabolic machinery of the cell to make target compounds. These systems also may be used to detect toxic chemicals in the environment such as groundwater contamination or chemical warfare agents. We propose the development of chemical sensor/actuator systems to detect target analytes. We will demonstrate the utility of these biosensors as tools for metabolic engineering, as well as develop methodogy applicable for building any desired biosensor. To demonstrate that a biosensor can be used to direct the

Metabolites
evolution of a metabolic pathway, we will first use a native transcriptional regulator to report on the relative concentrations of intracellular target compounds and we will use this regulator to direct the evolution of a biosynthetic pathway to make more of the target compound. Next, we will develop a selection cassette for the evolution of new transcriptional regulators with desired properties. Finally, we will use the selection cassette to evolve new transcriptional regulators to detect specific target molecules. Accordingly, the specific tasks of this proposal are (1) to use the endogenous transcriptional activator PrpR to direct the evolution of a propionate production pathway, (2) to build a reporter/selection (RS) cassette for the evolution of new biosensors, and (3) to evolve new DitR-based biosensors that sense different target compounds.

Project Title: BIOSYNTHESIS OF MICROBIAL POLYKETIDES Principal Investigator & Institution: Cane, David E.; Vernon K. Krieble Professor of Chemistry; Chemistry; Brown University Box 1929 Providence, Ri 02912 Timing: Fiscal Year 2002; Project Start 01-AUG-1977; Project End 31-JUL-2005 Summary: Ongoing studies of the ensymology of complex polyketide natural product biosynthesis will be continued and extended, with focus on the macrolide antibiotics erythromycin (1), methymycin (2), and tylosin (3), as well as the antitumor metabolite epothilone (4). Each of these metabolites is assembled by exceptionably large, multifunctional, modular proteins known as polyketide synthases (PKSs) that are closely related to fatty acid synthases, both biochemically and genetically. In addition, epothilone synthase contains additional catalytic activities belonging to the class of nonribosomal peptide synthetases (NRPSs). A combination of chemical, enzymological, and molecular genetic techniques this being used to elucidate the molecular basis for the programming of the complex series of reactions responsible for polyketide chain elongation. The emphasis in this work is on the elucidation of the mechanisms of multistep, enzyme-catalyzed transformations leading to formation of biologically important metabolites. It is expected that the results of these studies will be broadly applicable not only to the understanding of polyketide and other natural product biosynthetic processes in general, but will provide fundamental insights into how catalysis and molecular recognition control both product specificity and molecular diversity in Nature. 1) Deoxyerythronolide B synthase (DEBS) is a modular PKS that catalyzes the formation of 6-deoxyerythronolide B (5), the parent aglycone of erythromycin A. Individual modules of the DEBS protein, responsible for catalysis of a single round of polyketide chain elongation and functional group modification, can be expressed in E. coli. These modules will be used to study the biochemical basis for the specificity and selectivity of individual catalytic domains, particularly the ketosynthase (KS) domains that mediate the key polyketide chain-building decarboxylative condensation reaction. 2) The methymycin and tylosin PKSs have intriguing similarities and differences to the well-studied DEBS system. Individual modules of the methymycin/picromycin and tylactone PKSs will be expressed in E. coli in order to investigate their biochemical function and substrate specificity. 3) The EpoA protein, the loading module for the epothilone hybrid PKS/NRPS, will be expressed in E. coli in order to study the EpoAcatalyzed conversion of malonyl-CoA to acetyl-S-EpoA, the substrate for the NRPS module EpoB.

Project Title: BRAIN H2D MRS: IMPLEMATION AND INITIAL APPLICATIONS Principal Investigator & Institution: Wang, Zhiyue J.; Assistant Professor; Radiology; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2002; Project Start 15-AUG-2002; Project End 31-JUL-2005 Summary: (provided by applicant) The long-term objective is to apply 2D 1H magnetic resonance spectroscopy (MRS) techniques in studies of pediatric neurological disorders. 1H MRS is valuable for evaluating neurological brain diseases. However, there are limitations in current clinical 1H MRS examinations. Most peaks are crowded in a narrow aliphatic spectral window, and numerous low concentration metabolites are overshadowed by a few metabolites present in higher levels, and much valuable information is lost. Most metabolites have coupled spins, and 2D MRS separates the peaks in a second frequency dimension, greatly increasing the information content of the data. Application of 2D MRS in clinical examinations will enhance the abilities for diagnoses and patient management, and improve the understanding of disease processes. The specific aims are: (1) to implement 2D spin-echo double-quantum MRS pulse sequences for in vivo measurement of brain metabolites in 1.5T clinical scanners: (1a) to implement a localized pulse sequence optimized for GABA measurement; (1b) to implement localized pulse sequences for general detection of metabolites; (1c) to implement whole-brain measurement pulse sequences for general detection of metabolites. (2) to assign and evaluate peaks detected in the normal brain: (2a) to acquire spectra from metabolite solutions; (2b) to acquire brain spectra and baselines due to macromolecules in a group of adult normal volunteers; (2c) to assign the in vivo peaks and measure metabolite levels, and to determine optimal pulse sequences for studies of Aim 3; (2d) to acquire age-matched control spectra from normal children. (3) to explore the utility of the 2D MRS techniques in patients between the ages of 7 and 11 years: (3a) to study the effects of the ketogenic diet (KD) on brain GABA levels in seizure patients; (3b) to measure the brain?s level of branched chain amino-acids (BCAA) and keto-acids (BCKA) in maple syrup urine disease (MSUD); (3c) to test the hypothesis that low levels of brain galactitol are present even under a lactose restrictive diet; (3d) to study unassigned, unusual spectral peaks found in routine clinical MRS examinations. A localized 1D double-quantum filtered MRS pulse sequence will be modified into several 2D double quantum MRS pulses for localized and whole brain measurement. Different pulse parameters will be used for different types of spin systems. A frequency selective coherent transfer pulse will be used for optimal detection of GABA, and a broadband coherent transfer pulse will be used for all other 2D pulse sequences. The measurement procedures will be applied to normal subjects first. MRS measured GABA level before and after initiation of KD therapy will be compared in seizure patients and correlated with response. The MRS measurement of BCAAs and BCKAs will be conducted during metabolic crisis and in normal conditions in MSUD and correlated with clinical condition and serum BCAA and urine BCKA. In galactosemia, 2D MRS will be used to look for low levels of galactitol, and the MRS results will be correlated with the urine galactitol levels. 2D MRS will also be used to characterize unusual peaks found in clinical practice.

Summary: (provided by applicant): The goal of the proposed project is to systematically study biochemical markers of cerebral response to highly active antiretroviral treatment (HAART) in people with HIV associated cognitive impairment using proton (1 H) magnetic resonance spectroscopy (MRS). Metabolic findings will also be related to virological studies and indices of neuropsychological impairment. The specific aims of the proposed study are 1) to evaluate brain metabolites before and after treatment with HAART regimens in individuals with HIV-associated neurocognitive disorders (dementia and minor cognitive-motor disorder); 2) To relate changes in brain metabolites with alterations in CSF and plasma HIV RNA as a result of treatment; and, 3) To evaluate the effect of altering treatment strategies in those individuals who fail HAART treatment and initiate a new regimen after structured treatment interruption. It is hypothesized that concentrations of N-acetyl aspartate (NAA) will be lower, and concentrations of myo-lnositol and Choline will be higher in HIV+ participants with cognitive impairment than in those without cognitive impairment, and that these changes will become more normal in participants whose treatments are effective in reducing viral load in the CNS. It is also hypothesized that changes in NAP, myolnositol, and Choline from baseline in response to HAART treatment will be related to changes in neurocognitive functioning. The study will be linked to an already funded 5year research program at the San Diego HIV Neurobehavioral Research Center entitled "HIV Neurocognitive Disorders: CSF HIV RNA and Chemokines" (Ronald J. Ellis, PI). The study will compare individuals who are prescribed antiretroviral drug treatment regimens based on drug resistance phenotyping of plasma, or both plasma and CSF virus. These drug resistance assays will be used to select ARV agents to maximally suppress CSF virus. The proposed study will evaluate brain metabolites in 64 neurocognitively impaired HIV infected individuals, compared to 40 HIV infected individuals without neurocognitive impairment. All participants will undergo MRS scans at baseline, four weeks post-treatment, and 12 weeks post-treatment. Their HW RNA level will also be assessed at the same intervals through the parent study, and they will receive comprehensive neuropsychological evaluations at baseline and 12 weeks post-treatment. The proposed study may provide evidence for the utility of monitoring cerebral metabolites with MRS during treatment and may yield predictors of success or failure in treating HIV associated cognitive dysfunction.

Principal Investigator & Institution: Bolton, Judy L.; Professor; Medicinal Chem & Pharmacognosy; University of Illinois at Chicago 1737 West Polk Street Chicago, Il 60612 Timing: Fiscal Year 2002; Project Start 08-JAN-1999; Project End 31-DEC-2002 Summary: Tamoxifen remains the endocrine therapy of choice in the treatment of all stages of hormone-dependent breast cancer. In addition, large-scale clinical trials are in progress to determine the potential of tamoxifen to act as a chemopreventive agent in women considered at high risk for developing breast cancer. However, several studies have raised concern over the safety of chronic treatment with this drug. Alternate antiestrogens including droloxifene, toremifene, and idoxifene, may not be genotoxic probably because of different routes of metabolism which could lead to a decrease in amount and/or type of ultimate carcinogen(s). The central hypothesis of this project is that the formation of reactive intermediates is an important mechanism of carcinogenesis and/or cytotoxicity for certain antiestrogens. For example, tamoxifen can

17
be metabolized to at least three electrophilic metabolites of very different reactivity: quinone methides, carbocations, and o-quinones. The following specific aims are proposed: 1. Role of quinone methides, carbocations, and/or o-quinones in the carcinogenic and cytotoxic effects of antiestrogens. The carcinogenic potential of the proximate carcinogens from tamoxifen, droloxifene, toremifene, and idoxifene will be studied in C3H1 OT1/2 cells and their tumor promoting ability examined in JB6 cells. The biochemical effects of the antiestrogens and their metabolites will be investigated in human breast and endometrial cancer cell lines. 2. Investigate the effect of reactive metabolite structure on electrophilic and/or redox reactivity. The substituent effects on the electrophilicity/redox ability of the antiestrogen reactive intermediates will be investigated by measuring their ability to alkylate/oxidize DNA. Redox active metabolites will be tested by monitoring changes in reduced cofactors and by determining the formation of reactive oxygen species. 3. Determine if the antagonist/agonist activity of antiestrogen metabolites correlates with the extent of DNA damage in estrogen receptor positive cell lines. The Ishikawa cell system will be used to determine the estrogenic antiestrogenic and/or toxic effects of the proximate hydroxylated metabolites and the ultimate reactive intermediates. Cellular DNA from estrogen receptor positive and negative cells lines will be isolated after treatment with the test compound. The DNA will be hydrolyzed to deoxynucleosides (identified from Aim 2) and examined for covalent adducts and oxidative damage. These studies will greatly assist in the design of estrogen antagonists that maintain beneficial properties without generating genotoxic metabolites.

Project Title: CHEMICAL/BEHAVIORAL STUDIES ON HALLUCINOGENIC AGENTS Principal Investigator & Institution: Glennon, Richard A.; Professor; Medicinal Chemistry; Virginia Commonwealth University Richmond, Va 232980568 Timing: Fiscal Year 2003; Project Start 15-APR-1989; Project End 31-MAR-2008 Summary: (provided by applicant): We have shown that arylalkylamines of abuse can produce one or more of at least three distinct discriminative stimulus effects in rats: a 1(2,5-dimethoxy-4-methylphenyl)-2-aminopropane-like (D(c)M-like) effect typical of classical hallucinogens (H), a (+)amphetamine-like effect typical of stimulants (S), and a third type of effect that has not yet been well defined but is typified by the phenylalkylamine N-methyl-l-(4-methoxyphenyl)-2-aminopropane (PMMA) (P). The model implies three distinct effects, three distinct structure-activity relationships (SARs), and three distinct mechanisms of action. The actions, SARs, and mechanisms of action of phenylalkylamine hallucinogens and stimulants have been relatively well investigated. In contrast, almost nothing is known about the SAR and mechanism of action of PMMAlike agents. Furthermore, certain agents have been demonstrated to produce multiple effects and are best classified as, for example, H/P- or S/P- type agents; these agents likeiy act by composite mechanisms and likely possess composite SARs. The abused phenyiaikylamine MDMA ("Ecstasy') is such an agent. We have classified this agent as belonging to the S/P-category, and what is known about its actions and SAR are consistent with the model. Types of questions now being addressed include: What structural traits did MDMA-iike agents inherit from (+)amphetamine and which were inherited from PMMA? We have been able to antagonize the stimulus effects of MDMA; are the effects of both MDMA isomers inhibited to the same degree or by the same mechanism? Can the PMMA-stimulus be antagonized in a similar manner? Using primarily a drug discrimination paradigm [with groups of animals trained to
18
Metabolites
discriminate either DOM, (+)amphetamine, PMMA, MDMA, (-)MDMA, (+)MDMA from vehicle], we propose to investigate structure-activity relationships for PMMA-like activity, to study the stimulus mechanism of action of PMMA, and to classify various agents as to the type of effect(s) they produce. For example, the actions of numerous controlled (i.e., Schedule 1) substances are poorly understood; various novel street drugs (including their metabolites and synthetic by-products) are even less well understood. Investigation of such agents not only allows their classification, it also adds to the structure-activity data being collected that can ultimately be used to forecast the actions of newer agents. Compounds necessary for the studies are proposed for synthesis. Because stereochemistry plays a key role in the actions of many of the compounds (with enantiomers sometimes producing different effects), most will be examined as individual isomers. Where agents possess two chiral centers, all four isomers will be prepared and examined. Other studies relevant to the above model include examination of the stimulus effects of DOM and MDMA metabolites. The novel classification scheme provides a platform from which mechanism of action (and mixed mechanisms of action) can be investigated and unraveled. This will eventually lead to a better understanding of abuse prevention and treatment modalities. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CHOLINERGIC INSECTICIDE TOXICOLOGY Principal Investigator & Institution: Casida, John E.; Professor of Entomology; Environmntl Sci Policy & Mgmt; University of California Berkeley Berkeley, Ca 947205940 Timing: Fiscal Year 2003; Project Start 01-JUN-1998; Project End 31-JUL-2007 Summary: (provided by applicant): Neonicotinoids are the most important new class of insecticides of the last three decades, already accounting for about 10% of the world insecticide market and with major human exposure. They have the same nicotinic acetylcholine receptor (nAChR) target as nicotine but are much more potent and selective for insects. The long term objective is to define the mechanisms of selective toxicity for the major neonicotinoids, imidacloprid, thiacloprid, thiamethoxam and acetamiprid. The first specific aim is to establish the unique neonicotinoid and nicotinoid structural features for nAChR specificity and selective toxicity. The negatively-charged tip is proposed to confer potency and selectivity for insect nAChRs, prompting us to synthesize structural probes with this feature. The preferred conformation and configuration will be determined by X-ray crystallography and NMR and related to potency. Quantum mechanics studies will establish the electrostatic potential surface, molecular charge distribution and binding energy. The same approaches will be used to characterize the analogous nicotinoids selective for mammalian nAChRs. The second aim is to characterize nAChR subtypes, subunits and subsites that determine selective action. One goal is to establish the role(s) of alpha4beta2, alpha3beta2(and/or beta4) alpha5, or alpha7 and alpha1Gamma alpha1deltabeta1 subtypes in binding neonicotinoids and their metabolites relative to functional assays and selective toxicity. Drosophila nAChR and vertebrate nAChR subtypes are solubilized, purified by neonicotinoid- or nicotinoid-affinity chromatography, and labeled with potent azidoneonicotinoid and azidonicotinoid photoaffinity probes designed in this laboratory. The labeled subunits will be identified with particular attention to the proposed cationic subsite(s) in insects and pi-electronrich subsite(s) in vertebrates. Molecular modeling of the detailed binding site architecture will then relate the structure of the Drosophila D-alpha subunits and the acetylcholine binding protein to the findings on photoaffinity labeling. The third aim is

to define neonicotinoid metabolic activation and detoxification relative to selective toxicity. Metabolites of imidacloprid, thiacloprid, thiamethoxam and acetamiprid will be characterized and synthesized for receptor, toxicity and functional assays to clarify selective metabolic activation versus detoxification. Toxicokinetic studies with mice will relate the brain levels of neonicotinoids and their desnitro and descyano metabolites (toxic iminium derivatives) to the poisoning signs. Continuing investigations will define human cytochrome P450 isozyme specificity in metabolism of neonicotinoids and characterize human microsomal "neonicotinoid nitroimine reductase" that generates unique hydrazone and triazolone derivatives of imidacloprid.

Project Title: CITRUS/CANCER ASSOCIATION IN MEDITERRANEAN DIET Principal Investigator & Institution: Hakim, Iman A.; None; University of Arizona P O Box 3308 Tucson, Az 857223308 Timing: Fiscal Year 2002; Project Start 01-FEB-1998; Project End 31-JAN-2004 Summary: (Applicant's Description) The goal of this proposal is to improve understanding of diet-cancer associations, by developing a dietary assessment technique which would allow accurate reporting of previous and recent citrus (and hence dlimonene) consumption. While the Mediterranean diet is associated with lower cancer rates, food preparation techniques in the Mediterranean area include more use of citrus peel than do U.S. preparation styles, possibly resulting in higher levels of d-limonene intake. In animal models, d-limonene in the diet has resulted in tumor regression. The objectives of this project are to develop and validate a supplement to the Arizona Food Frequency Questionnaire, and to further knowledge of the interrelationship of citrus consumption, dietary d-limonene and human plasma levels of d-limonene and/or its main metabolites, perillic acid and dihydroperillic acid. The first aim of this project is to assess levels of consumption of d-limonene by (1) assessing the limonene content of different types of foods prepared with high amounts of citrus pulp and/or peel to supplement food composition database, (2) developing and validating a dietary questionnaire to assess citrus peel, pulp, and juice consumption, which can be converted to mg d-limonene per day, (3) and applying the developed questionnaire into ongoing edipemiologic research at the Arizona Cancer Center. The second aim is to prepare for future clinical trials by (1) determining the acceptability of citrus as dietary supplements for cancer primary prevention trials, (2) assessing plasma levels of d-limonene and its metabolites in subjects after one month of high citrus consumption, and (3) determining whether d-limonene or its metabolites can serve as a biomarker for compliance with dietary citrus peel consumption intervention. This proposal for research will be the major component of a 5 year Academic Investigator Award in which cancer prevention and epidemiology will be the focus. These studies along with continued course work in advanced epidemiology and biostatistics, and experience in teaching will provide the experience and expertise needed to function as a successful, independent cancer investigator in the future.

Project Title: CO-CARCINOGENIC ACTIVITY OF NITROSAMINE METABOLITES Principal Investigator & Institution: Peterson, Lisa A.; Associate Professor; Environ & Occupational Health; University of Minnesota Twin Cities 200 Oak Street Se Minneapolis, Mn 554552070 Timing: Fiscal Year 2003; Project Start 05-MAY-1993; Project End 31-MAR-2007

Metabolites
Summary: (provided by applicant): The mechanism of tumor induction by unsymmetric nitrosamines is poorly understood. Alpha-hydroxylation activates these carcinogens to DNA alkylating agents by generating a metabolite that decomposes to an aldehyde and a diazohydroxide. The diazohydroxide, presumably via a diazonium ion, alkylates DNA. Unsymmetric nitrosamines have two activation pathways that lead to two different types of DNA adducts. Interactions between these two pathways likely contribute to the carcinogenic activity of the nitrosamine. In addition, the aldehyde metabolites are themselves chemically reactive and may contribute to the toxicological properties of nitrosamines. Interactions between the various reactive nitrosamine metabolites will be explored with 4-(methylnitrosamino)-l-(3-pyridyl)-l-butanone (NNK). This tobacco-specific nitrosamine selectively induces lung tumors in laboratory animals and is a possible human carcinogen. NNK is activated to either a methylating agent or a pyridyloxobutylating agent. Experimental data support a carcinogenic mechanism for this compound in which the formation and persistence of O6methylguanine (O6-mG) is important for the initiation of tumorigenesis by NNK. Pyridyloxobutylating agents and NNK-derived aldehydes, formaldehyde and 4-oxo-1(3-pyridyl)-1-butanone, are capable of interfering the repair of O6-mG by O6alkylguanine-DNA alkyltransferase (AGT). In vivo levels of the AGT substrate pyridyloxobutyl DNA adduct, O6-[4-oxo-4-(3-pyridyl)butyl] - guanine, are insufficient to explain the extent of O6-mG persistence in NNK-treated mice. Therefore, there appears to be other mechanisms by which nitrosamine metabolites interfere with O6mG repair. The objective of this application is to explore the mechanisms by which nitrosamine metabolites can reduce the repair of O6-mG by AGT. The central hypothesis is that nitrosamine metabolites can inactivate DNA repair pathways, leading to increased persistence of promutagenic adducts. These mechanisms differ from a mechanism involving competition between O6-alkylguanine adducts for repair by AGT. We plan to test our central hypothesis by pursuing the following specific aims: 1) Determine the importance of direct alkylation of AGT by diazohydroxides on AGT depletion; 2) Determine the contribution of aldehydes to the depletion of AGT following nitrosamine exposure; 3) Determine the effect of nitrosamine metabolites on the degradation rate of inactivated AGT; 4) Determine the ability of nitrosamine metabolites to influence the rate of AGT protein synthesis. The results of our studies will lead to a better understanding of mechanisms of lung cancer induction. In addition, this mechanism is likely applicable to other unsymmetric nitrosamines as well as carcinogenic mixtures such as tobacco smoke, a known human carcinogen.

Project Title: COORDINATE REGULATION OF SPHINGOLIPID PRODUCTION Principal Investigator & Institution: Holleran, Walter M.; Northern California Institute Res & Educ 4150 Clement Street (151-Nc) San Francisco, Ca 941211545 Timing: Fiscal Year 2003; Project Start 20-SEP-2003; Project End 31-JUL-2008 Summary: The epidermis is faced with the daunting task of generating a permeability barrier that allows survival of mammals in a xeric, terrestrial environment. To accomplish this goal, the epidermis generates the stratum corneum (SC), with its highlyhydrophobic, lipid-enriched extracellular matrix, organized into lamellar bilayers. To generate these unique protective structures, keratinocytes must synthesize extensive quantities of cholesterol and sphingolipids, along with free fatty acids (FA), and deliver an approximately equimolar ratio of these barrier lipids to the SC. These three key lipids, and/or their immediate precursors, are removed from the intracellular, membrane-lipid pool by sequestration within an epidermis-specific, secretory organelle,

21
the lamellar body, and delivered to the SC interstices coincident with terminal differentiation. Coordinate regulation of the synthesis of these lipid classes, and their subsequent sequestration into lamellar bodies, not only sustains a flow of lipids in an appropriate equimolar ratio to meet permeability barrier requirements, but also quickly funnels newly-synthesized ceramides (Cer) into glucosylceramides (GIcCer), thereby avoiding premature, Cer-induced apoptosis. It is our hypothesis that epidermal lipid synthesis is co-regulated and co-ordinated with both cholesterol and FA production: e.g., as cholesterol and FA synthesis increase in response to barrier requirements, nuclear hormone receptor-activating oxysterol and free fatty acid metabolites will be generated, which in turn up-regulate Cer and GIcCer synthesis. Conversely, when cholesterol and FA synthesis declines, fewer lipid metabolites will be generated and NHR-dependent activation of SPT and GCS also will decline. We propose first, to identify those NHR agonists that regulate Cer and GIcCer synthesis in relation to differentiation, and then to determine the basis, as well as the receptor-mediated requirement for such regulation (Aim 1). After identifying the most-potent NHR activators, we will determine how SPT and GCS are regulated by these agents at a molecular level (Aim 2). Finally, we will assess how Cer/GIcCer production are coregulated with cholesterol and FA synthesis, to generate the equimolar mixture required for the barrier (Aim 3). Since the formation of the epidermal barrier lipids, and subsequent generation of the extracellular lamellae, are late steps in epidermal differentiation, the proposed studies will result in significant new information regarding the coordinate regulation of barrier lipid generation and epidermal homeostasis.

Project Title: CORE--BIOANALYTICAL Principal Investigator & Institution: Blair, Ian A.; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 30-AUG-2002; Project End 31-JUL-2007 Summary: The Bioanalytical Core will serve all projects in this Program. It will consist of an Analytical component (directed by Dr. Blair-Center for Cancer Pharmacology, University of Pennsylvania), and a Synthetic component (directed by Dr. Harvey-The Ben May Institute, University of Chicago). The major roles of the Analytical component are: 1) to assess the purity of PAHmetabolites used by all Project Investigators (Projects 1-3), and this is pertinent to the use of anti- and syn-diol epoxides which hydrolyze to tetraols; 2) to quantitate PAH-metabolites formed in cell culture experiments, once structural validation of the analyte has been achieved; 3) to quantitate concentrations of PAH-o-quinones used in cell culture experiments, once structural validation of the analyte has been achieved; 4) to quantitate covalent modifications to DNA by PAHmetabolites and reactive oxygen species in Project 1 once methods development and validation has been achieved in Project 2; and 5) with support from the Administrative Core A to act as a liaison between the NCI Chemical Carcinogen Reference Standard Repository and Project Investigators to maintain stocks of individual PAH-metabolites and PAH-synthons. The analytical component will be reliant on a PAH-Database and a Program Database maintained in the Administrative Core-A these will monitor stocks of PAH-metabolites and perform statistical analysis of PAH-DNA adducts. The Analytical component of Core B contains a triple-quadruple mass spectrometer and an ion-trap mass spectrometer. The Synthetic component of Core B will develop efficient synthetic strategies to: 1) the major stable benzo[a]pyrene diol-epoxide (BPDE) adducts [(+) and ()-anti-BPDE-N6-dAdo (trans-isomers); (+) and (-)-anti-BPDE-N6 dAdo (cis-isomers), (+) and (-) anti-BPDE-N2-dGuo (trans-isomers) (+)-and (-)-anti-BPDE-N2-dGuo

(cisisomers)], major radical-cation BP depurination adducts [N7- and C8-guanine and N7-adenine adducts of BP], and the stable and depurinating adducts of BP-2 7,8-dione [N -dGuo, N6-dAdo, N7-guanine and N7-adenine]. These reference standards will be used in Projects 1 and 2 to identify unknowns; and 2) to develop synthetic strategies to the stable and depurinating adducts of BA-3,4- dione [N2-dGuo, N6-dAdo, N7-guanine and N7-adenine] and the stable and depurinating adducts of DMBA-3,4-dione [N2dGuo, N6-dAdo, N7-guanine and N7- adenine] for their detection in cell culture paradigms in collaboration with Project 1. Via Core A, we will inform the Repository of the availability of novel PAH-DNA adducts for distribution to the PAH-research community. This will establish a symbiotic relationship between Core B and the Repository. Thus, Core B is a vital component to the success of all Projects of the PPG and may impact PAH-DNA adduct research in general. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CORE--CHEMICAL ANALYSIS Principal Investigator & Institution: Knize, Mark G.; University of Calif-Lawrnc Lvrmr Nat Lab Lawrence Livermore National Lab Livermore, Ca 945509234 Timing: Fiscal Year 2002; Project Start 19-APR-2002; Project End 31-JAN-2007 Summary: (provided by applicant): The Chemical Analysis Core Facility will support experiments by instrumental analysis of foods and urine samples and by supplying heterocyclic amine chemicals to the other Projects. Food analysis for heterocyclic amines is a longstanding area of expertise, and will be used to support cooking experiments to understand heterocyclic amine formation and devise practical ways to reduce or eliminate them. Other food samples will be analyzed in support of studies of an at-risk population of African-American men. Analysis of human urine samples will be undertaken for three purposes: 1) to determine the uptake of PhIP and the total amount of metabolites to support experiments in dietary intervention to reduce exposure, and 2) to determine individual metabolic phenotype and the relationship of the metabolism of PhIP with other phenotypic endpoints, and 3) to determine the relative amounts of PhIP metabolites in individuals participating in a prostate cancer study. Methods used will be solid-phase extraction and analysis by LC/MS/MS detection. The human feeding procedures, urine and blood sample collection, and inventory and storage will also be part of this core?s function. The heterocyclic amine chemicals will be purchased and synthesized, and supplies maintained for distribution to users in the Exposure Reduction and Prevention, Carcinogenesis of Cooked Food Mutagens, Metabolic Susceptibility to Cooked Food Carcinogens, and HA Macromolecular Adducts as Biomarkers groups in support of their specific experiments.

vivo dosing protocols. The availability of standards multiply labeled with stable isotopes from the Synthesis Laboratory will crucial to the development of isotope dilution methods for ultra-trace analysis of metabolites and DNA and protein adducts by the Mass Spectrometry Facility. Specific classes of compounds for which synthetic needs have been established are: Project 1, tricyclic nucleobases, deoxynucleosides and deoxynucleotides; protein adducts of malondialdehyde and 4-hydroxynon-2-enal; cysteine contual basis for dosing protocols; Projects 3 and 8, S-phenyl-d5-cysteine and mercapturic acid; Project 4, fungal metabolites of PAH and Project 5, 13C-labeled PAH phenoles. Synthesis Laboratory will also be available for consultation on questions involving structural characterizations, and application of spectroscopic techniques to problems of quantitation and characterization. Other areas where Core expertise may be useful to Program Projects are in the application of structure-activity relationships to direct efforts in isolation and characterization of products of metabolism or nonenzymatic decay. The Core has access to 500 and 500 MHz NMR spectrometers with multinuclear and variable temperature capability. Core personnel are trained operators, proficient in all aspects of data acquisition, work-up and interpretation, and will fill the NMR needs of program projects. Additional techniques of physical characterization accessible through the Core are circular dichroism X-ray crystallography, EPR and FTIR. The Mass Spectrometry Facility will provide support for Program Projects when mass spectrometry requirements are beyond the capacity of equipment belonging to Program Projects or when extensive methods development is necessary. The Mass Spectrometry Facility performs characterization and ultra-trace analysis on a routine basis by a variety of mass spectrometric techniques, and is also involved in developmental work. Major objectives of the Mass Spectrometry Facility will be to develop on-line sample clean-up and analyte pre-concentration procedures and to apply HPLC/MS/MS techniques to characterization of DNA adducts, protein adducts and PAH metabolites.

Project Title: CORE--MASS SPECTROMETRY Principal Investigator & Institution: Borgerding, Anthony J.; University of North Dakota 264 Centennial Drive Grand Forks, Nd 58202 Timing: Fiscal Year 2002; Project Start 15-SEP-2002; Project End 31-AUG-2007 Summary: This core facility will support the research of the COBRE investigators. Specifically, high resolution LC/MS/MS instrumentation housed in the facility will be used in Project 2 (Porter) for identification of proinflammatory arachidonic acid metabolites generated by CGRP stimulated THP-1 cells, and to quantitate the amount of prostaglandin compounds hypothesized to be produced from an increased expression of COX-2. These measurements will benefit studies of the characterization of the neuroinflammatory CGRP receptor. In Project 3 (Picklo), MS will be utilized in studies of the mechanism of HNE metabolism in CNS tissue. High resolution LC/MS will be used to identify and quantitate HNE metabolites, and MALDI/TOF will be used to identify novel detoxification enzymes. Project 4 (Murphy) will utilize the mass spectrometry core facility to fulfill analysis requirements for two specific aims. These aims address phospholipid head group flux and turnover in neuronal, astroglial, and stably transfected HEK-293 cell lines. LC/MS and GC/MS will be used to measure labeled and unlabeled phospholipids to study the kinetics of compound incorporation. The core facility will consist of three instruments. One instrument will be a highresolution tandem mass spectrometer (MS/MS, QQTOF geometry) with an ESI source and a liquid chromatography interface. In addition, we will acquire a MALDI/Time of Flight (TOF) instrument and a gas chromatography 1 ion trap system. The combination

of these instruments will result in a facility capable of providing molecular weight and structural information for all of the wide variety of samples that will be generated in this COBRE. The facility responsibilities (training users and helping with data analysis, operation and maintenance, assuring that the standard operating procedures are followed) will be divided between between the facility director and a research technician.

Project Title: CORE--MASS SPECTROMETRY Principal Investigator & Institution: Deinzer, Max L.; Professor; Oregon Health & Science University Portland, or 972393098 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2003 Summary: The broad objective of this Mass Spectrometry Core is to provide high- end mass spectroscopy techniques to support the biomedical and non- biomedical projects in this Superfund Basic Research Program and to develop and apply a new, highly specific and sensitive mass spectroscopy technique to detect and quantify environmental compounds and their metabolites. These compounds will include tetrachloroethene, 1,1,2- trichloroethene, cis-1,2-dichloroethene, vinyl chloride, chloroacetaldehyde and chloroform. The development of this new instrument will require the construction of a gas chromatograph electron monochromater-time-of flight-mass spectrometer (GC-EMTOF-MS) to analyze negative ions using the EM for the production of monoenergetic beams of ionizing electrons in combination with pulsed extraction. To support the other biomedical and non-biomedical projects in this application, we will develop and apply mass spectrometric methods to analyze adducts formed between proteins and hydrocarbon solvent metabolites. We will develop mass spectrometric methods for analyzing protein and peptides resulting from reaction with 2,5-hexanedione, and analogs, 3-methyl-2,5-hexanedione, 3,4-dimethyl-2,5-hexanedione, 3-4- diethyl-2,5hexanedione, 2,9-dimethyl-4,7, decanedione and 1,2- diacetylbenzene. The effects of gamma-diketone hydrocarbon adducts on the thermal stability of neurofilament protein structures will be a assessed by hydrogen-deuterium exchange (H/D) exchange and equilibrium thermal denaturation studies in conjunction with electrospray mass spectroscopy. The effects of hydrocarbon adducts on the conformation of neurofilament protein subunits will be determined by kinetic H/D exchange experiments, together with electrospray mas spectrometry.

Project Title: CORE--SPECIALIZED ASSAY Principal Investigator & Institution: Kulkarni, Rohit N.; Assistant Professor; Joslin Diabetes Center Boston, Ma 02215 Timing: Fiscal Year 2002; Project Start 30-SEP-1986; Project End 31-MAR-2007 Summary: (provided by applicant): The Core currently provides radioimmunoassay (RIA), immunogenetic, and other basic biochemical assays performed in support of the studies carried out on the General Clinical Research Section (GCRC), as well as animal studies taking place in the laboratories of individual investigators. Over the last 5 years there has been a tremendous increase in the number of rodent mouse models created to study various aspects of types 1 and Type 2 diabetes, their complications and obesity. At the Joslin Diabetes Center there are currently at least about 68 rodent models that are being studied and 17 more are in various stages of being created. This has resulted in the obvious need for the measurement of rodent hormones and metabolites on a large scale.
Studies
25
Assays are currently performed by individual laboratories using different kits and are not cost-effective. It is proposed to expand the current Core at Joslin to undertake measurement of the multiple hormones, metabolites and other markers of diabetes required by these animal studies. The new Specialized Assay Core (stated as Core here onwards) will be responsive to the varied requirements of investigators by providing an assay service and back-up support for experiments involving humans and animals. Furthermore, the facility will also provide advice and consultation, and if necessary develop and perform additional assays for novel hormones, metabolites and markers when required by the investigators. In a large institution such as the Joslin, there are often multiple investigators measuring similar parameters as part of their basic research or for clinical protocols. In the operation of any central assay Core, greater efficiency is created by planning and integrating facilities and personnel. This results from sharing antibodies, reagents and equipment, allows more economic use of expensive or limited materials, and provides for more focused training of junior investigators. It is proposed that all the human insulin assays (accruing from GCRC and other studies) will be performed at the BIDMC assay Core, which is equipped to handle the current number of human insulin assays performed at the Joslin. The BIDMC unit is the Core laboratory of the NIH-funded GCRC and will be able to assay human samples for insulin and thereby provide for a single center for both Joslin and BIDMC investigators. Consequently, this will free up a portion of the current time available for the technician to take on more of the DERC-related insulin assays and if time permits to focus on setting up, maintaining and running the additional different assays in the proposed Specialized Assay Core.

Project Title: DETECTING CRACK AND OTHER COCAINE USE WITH FASTPATCHES Principal Investigator & Institution: Liberty, Hilary J.; Principal Investigator; Social Sciences Innovations Corporation 71 W 23Rd St, 8Th Fl New York, Ny 10010 Timing: Fiscal Year 2004; Project Start 15-SEP-2000; Project End 31-JAN-2006 Summary: (provided by applicant): PharmChem Inc. has developed a new sweat patch product, the FastPatch TM, which reduces minimum wear times to detect cocaine and most other drugs of abuse from the full day typically required with standard sweat patches (Liberty et al., 1999a) to 20 or 30 minutes through mild heating (Liberty, 2003). Additionally, there is an increasing need and growing market for the detection of crack use distinct from other cocaine. Recent research (Martin et al., 1989) has identified unique pyrolytic metabolites of crack, anhydroecgo-nine methylester (AEME) and ecgonidine (ECD) through GC/MS. It is likely that a low-cost EIA procedure for detection of crack use will be available within a year, increasing the market potential for detection using a Fastpatch (tm). During Phase I, 180 subjects wore two FastPatch prototypes (one on each hand) and only one patch per subject was needed to obtain sufficient sweat eluate for GC/MS. This finding has positive market potential. Cocaine use was detected in sweat of 92.4 percent of subjects, comparable to 91 percent with EMIT urinalysis in a high prevalence sample. Crack metabolites were successfully detected in 54 percent of subjects. While there were no significant differences in detection rates between 15, 20, and 30 min. wear periods, all wear periods successfully detected substantial cocaine/crack use, and a shorter 10 min. condition will be tested. This finding has positive market potential. During Phase II, these changes will occur: Fast patches will be worn in moderate and low prevalence samples, a shorter wear period will be added, more biological tests will be included (e.g., standard sweat patches and GC/MS of urine), testing for more drugs (heroin and marijuana), data

collection will expand to include both a residential drug treatment program and a workplace, low-prevalence sample, the latter a venue with positive market potential. The FastPatch avoids problems with urinalysis such as violations of privacy, dilution or substitution of specimens, possibility of disease transmission, and transport of noxious fluids. Advantages over the standard sweat patch include a longer window of detection (2-3 wks. versus 2-3 days) and a shorter minimum period of wear needed to detect most drugs (10-20 m n. versus 24 hrs.).

Project Title: DHEA--PPAR DEPENDENT & INDEPENDENT MECHANISMS OF ACTION Principal Investigator & Institution: Prough, Russell A.; Professor; Biochem and Molecular Biology; University of Louisville Jouett Hall, Belknap Campus Louisville, Ky 40292 Timing: Fiscal Year 2002; Project Start 15-MAR-1999; Project End 31-DEC-2002 Summary: The proposed studies will evaluate the mechanisms by which dehydroepiandrosterone (DHEA) and its metabolites alter the metabolic activation of and block early steps in the promotion phase of chemical carcinogenesis and toxicity. Currently, DHEA, a potent peroxisome proliferator (PP) is being used in a number of human trials to enhance immune function and ameliorate several metabolic disorders, but humans appear to be a species which is not highly responsive to PP. Our preliminary results, correlated with the literature, suggest that DHEA and its metabolite function in both Peroxisome Proliferator Activated Receptor Alpha (PPARalpha)dependent and independent pathways. Our goals to characterize the PPARalphaindependent actions of DHEA or one of its metabolites are encapsulated in four specific aims: 1. Establish whether metabolites of DHEA serve as proximal inducers of peroxisome proliferation on other processes specific for DHEA action using cell-based reporter assays. The metabolites of DHEA formed by rat, hamster and human liver microsomes will be characterized by GC/MS and the enzymology of their formation deducted using specific inhibitors. Cell-based reporter assays with PPARalpha expression constructs and fatty acyl-CoA oxidase reporter constructs will test their role is ligand/activators for PPARalpha. 2. Characterize the properties of DHEA or any active metabolites involving PPARalpha or the non-classical glucorticoid induction mechanism described by Guzelian and Kasper. Our preliminary data suggests that CYP2Bl and CYP3A are induced by DHEA in vivo, but not by other peroxisome proliferators. Since the CYP4 enzyme subfamily are not good catalysts of PAH metabolism, CYP2Bl and 3A23 must account for enhanced metabolism possibly due to the non-classical mechanism of induction. The effects of DHEA in rat and human hepatocytes will address this possibility; PPARalpha knock-out mice will be used to dissect PPARalpha-dependent and independent pathways of regulation. 3. Utilize the technique of Differential Display to elucidate gene products induced or suppressed by DHEA in rats in vivo or cultured human hepatocytes, relative to other PP. The technique of Differential Display will be utilized to observe genes whose expression is altered (induced or repressed) by DHEA, but not by a prototype PP, nafenopin. This will allow us to ascertain large differences in mechanism between DHEA and other PP, in addition to regulation of CYP2B, CYP3A and CYP2C11 expression and related human genes. 4. The goal of Aim 4 is to characterize the PPARalpha-independent molecular regulation of P450s and other genes. Genes which we show are not regulated through PPAR will be studied by preparing reporter constructs with 5'-flanking regions of those genes to evaluate PPAR- independent pathways of DHEA action.

Project Title: DIETARY SOY/ISOFLAVONES AND URINARY ESTROGEN METABOLITES Principal Investigator & Institution: Tseng, Marilyn M.; Associate Member; Fox Chase Cancer Center Philadelphia, Pa 191112434 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JUL-2004 Summary: (provided by applicant): Research on potential cancer-protective effects of soy and isoflavones has led to an increase in the availability and consumption of soy products in the US. Yet conflicting scientific evidence raises the concern that high levels of intake might actually increase breast cancer risk. Whether current levels of soy and soy isoflavone intake are sufficiently high to affect breast cancer risk is unknown largely because of a lack of convenient, current, and validated methods of assessing intake. The objectives of the proposed study are to (1) evaluate the validity of overnight urine samples as a method of assessing soy isoflavone intake, and (2) examine associations between soy/isoflavone intake and urinary estrogen metabolites. Participants will be drawn from a program at Fox Chase Cancer Center for women at high breast or ovarian cancer risk. The study will include 50 women with either very high or low soy intake based on questionnaire data. Participants will complete a soyfood questionnaire and provide four 24-hour urine specimens over a one month period, with overnight samples collected in separate containers. Urines will be analyzed for isoflavones, primarily daidzein and genistein, and for estrogen metabolites including 2-, 4-, and 16alphahydroxy estrogens. Isoflavone levels in overnight urine samples will be evaluated for validity by examining their correlations with isoflavone levels in 24-hour urine specimens. We will use multiple linear regression to examine associations of soy/isoflavone intake with urinary estrogen metabolites. The proposed research will provide useful information towards assessment of soy/isoflavone intake in a non-Asian sample. It is also an opportunity to add to limited knowledge on soy/isoflavone intake and its association with urinary estrogen metabolites as markers of breast cancer risk. Findings from this research will contribute information towards a soy supplementation trial to evaluate modification of soy/isoflavone intake as a means of reducing risk of breast cancer, a disease for which few preventive measures are available.

Project Title: DISRUPTION OF ESTROGENIC RESPONSES BY PCB-PAH MIXTURES Principal Investigator & Institution: Arcaro, Kathleen F.; Research Assistant Professor; Veterinary and Animal Sciences; University of Massachusetts Amherst 408 Goodell Building Amherst, Ma 01003 Timing: Fiscal Year 2002; Project Start 01-FEB-2000; Project End 31-JAN-2004 Summary: There is widespread concern that exposure to chemicals in the environment may be related to the observed increase in the incidence of breast cancer. Among the chemicals of concern are polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), which have the potential to disrupt estrogenic responses. It is difficult to predict the health effects of exposure to complex mixtures of these chemicals because individual congeners of PCBs and PAHs can be either estrogenic or antiestrogenic and act through a variety of mechanisms potentially leading to additive, antagonistic or synergistic effects. Furthermore, the microbial reductive dechlorination of PCBs and the metabolic transformation of both PCBs and PAHs within the body, may

Metabolites
substantially alter the activity of these mixtures. It is hypothesized that reductive dechlorination of PCBs increases the estrogenic activity of the resulting mixture, and that metabolism of PCBs and PAHs further alters the estrogenic and anti-estrogenic activity of these mixtures. Thus, the objective of this proposal is to determine how mixtures of PCBs and PAHs may interact and modulate estrogenic activity in human cells. Specifically we will: 1) Determine the estrogenic and anti-estrogenic activity of relevant complex mixtures of PCBs and PAHs. Extracts from sediment samples and mixtures reflecting the composition of PCBs and PAHs detected in human tissue, food and water will be tested in human breast cancer cells for their estrogenic and antiestrogenic activity. 2) Determine how mixtures of PCBs and PAHs alter estrogenic activity and assess whether knowledge of the activity of the individual components is sufficient to predict the activity of the mixture. Mechanisms to be investigated include, estrogen receptor (ER) binding, regulation of ER level, metabolism of 17-estradiol metabolism of PCBs and PAHs in breast cancer cells. The nature of the interactions will be explored using full dose-response curves and probit analysis. 3) Determine the extent to which the estrogenic and anti-estrogenic activity of a mixture is altered by metabolism in human liver microsomes, and identify the major active metabolites. Metabolites generated from incubations in human liver microsomes, and identify the major active metabolites. Metabolites generated from incubations in human liver microsomes will be tested for their estrogenic and anti-estrogenic activity in human breast cancer cells. Knowledge gained from these studies will provide insight into the relationship between exposure to environmental estrogens and health risk.

BUTENEDIOL
Principal Investigator & Institution: Powley, Mark W.; Environmental Sciences & Engr; University of North Carolina Chapel Hill Aob 104 Airport Drive Cb#1350 Chapel Hill, Nc 27599 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 31-JAN-2005 Summary: (provided by applicant): The main purpose or the proposed research is to determine the formation of potentially mutagenic metabolites in the 1,3-butadiene (BD) metabolic pathway leading to MI, a major urinary metabolite in humans. To understand this pathway, tissues from female mice and rats exposed to 3-butene-1,2-diol (BD-diol) will be used. BD-diol is the hypothesized immediate precursor of two potentially mutagenic metabolites, hydroxymethylvinylketone (HMVK) and 3,4-epoxy-1,2butanediol (EB-diol), and is also a precursor to MI. The first hypothesis to be tested is that HMVK, but not EB-diol, is formed in B-diol exposed animals in an exposuredependent manner and therefore contributes to mutagenicity observed in animals exposed to BD-diol and BD. The second hypothesis is that a hemoglobin adduct of HMVK can serve as a biomarker of BD-diol and BD exposure. In testing these hypotheses we will accomplish several aims. The first specific aim is to develop methods to measure promutagenic adducts formed by HMVK, specifically 1,N2propanodeoxyguanosine adducts, in BD-diol exposed animals. Another specific aim is to develop methods to measure the hemoglobin adduct of HMVK in the exposed animals. The third specific aim is to measure DNA and hemoglobin adducts of EB-diol. The results of these experiments will demonstrate the formation and possible contribution to mutagenicity, of HMVK and EB-diol following metabolism of BD-diol. The final specific aim is to measure the HMVK adducts in BD exposed animals and humans. The proposed research will help explain a critical, but not fully understood, BD

metabolic pathway. This will improve our understanding of BD metabolism as a whole and ultimately increase our ability to accurately assess the risk of BD to humans. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: ENDOTHELIAL DYSFUNCTION IN INSULIN RESISTANCE Principal Investigator & Institution: Busija, David W.; Professor; Physiology and Pharmacology; Wake Forest University Health Sciences Winston-Salem, Nc 27157 Timing: Fiscal Year 2003; Project Start 01-APR-2002; Project End 31-MAR-2005 Summary: (provided by applicant): The insulin resistant (IR) syndrome is associated with an increased incidence of hypertension and cardiovascular (CV) disease. Data from the applicant's laboratory suggests that endothelial dysfunction may be the mechanism that links IR to CV disease. Previous studies show impaired endothelium-dependent relaxation in small mesenteric and coronary arteries from IR rats. This dysfunction appears to be secondary to a defect in endothetium-derived hyperpolarizing factor (EDHF). These data support the existence of a situation where the EDHF dilator component is selectively impaired and provides a model to assess mechanisms leading to impaired EDHF function. Moreover, it provides us a model to assess compensatory responses of other endothelium derived relaxing factors to an EDHF deficit. The overall hypothesis to be examined is that impairment of endothelium-dependent dilator capacity occurs during IR. Specific hypotheses to be tested are (1) Endothelium dependent relaxation is impaired in small mesenteric arteries to physiologic as well as pharmacologic stimuli. (2) Restoration of normal endothelium function occurs after cessation of fructose-rich diet. (3) Endothelial dysfunction associated with IR is due to a decreased production of EDHF. (4) Decreased substrate availability and/or abnormally low levels of cytochrome P450 (CYP) isoforms account for decreased EDHF production. (5) Endothelial dysfunction associated with IR is due to decreased sensitivity of potassium channels on vascular smooth muscle to EDHF. (6) The NO and prostacyclin systems do not compensate for this loss of dilator capacity. To test these hypotheses, two specific aims will be addressed. Specific aim 1. Characterize the nature of impaired vascular function in insulin resistance. First, we will assess whether IR induced impairment of endothelium-dependent relaxation is stimulus dependent. Second, we will explore the vascular effects of insulin in the setting of IR. And third, we will determine the vascular characteristics of reversal of endothelium dysfunction after cessation of fructose feeding. Specific aim 2. Determination of the mechanism of impaired endothelium-dependent dilation in insulin resistance. First, we will investigate the effect of lR on dilator responses to exogenous arachidonic acid. Second, we will explore the effects of IR on synthesis of bioactive metabolites of arachidonic acid. Third, we will examine the relationship between endothelial function and levels of CYP and NO synthase protein. Fourth, we will determine the effect of application of exogenous arachidonic acid metabolites (epoxyeicosatrienoic acids) on vascular tone. These data will determine mechanisms of endothelial dysfunction in IR. Moreover, the specific role of EDHF and mechanisms for its dysfunction will be determined. This project employs physiologic, cellular, and molecular biology techniques to address the proposed questions. Findings from this project may provide important information that can be used to design treatments to prevent the cardiovascular complications of IR.

Metabolites
Timing: Fiscal Year 2002; Project Start 01-AUG-1999; Project End 31-JUL-2004 Summary: A serious obstacle to the rational design of innovative approaches for preventing and/or treating osteoporosis is the idiopathic nature of postmenopausal bone loss. Menopause is the most important risk factor for osteoporosis. However, not all postmenopausal women develop osteoporotic fractures indicating that cessation of the menstrual cycle is insufficient to fully account for the disorder. Our working hypothesis is that the denovo production and metabolism of estrogens are among the most important factors influencing the rate of postmenopausal bone loss. Estrone (E1) and its metabolites, 16alpha-Hydroxyl estrone ( (16alpha-OHE1) and 2-hydroxyesterone (2-OHE1), are the most abundant estrogens in postmenopausal women. 16alpha-OHE1 has been recently shown to be a negative risk factor (reduced risk) for postmenopausal bone loss, whereas 2-OHE1 has been positive risk factor (increased risk). 2-OHE1 does not have estrogenic activity in ovariectomized (OVX'd) rats. In contrast, 16alpha-OHE1 appears to be a tissue selective estrogen agonist with a profile of activity similar to the anti-breast drug tamoxifen; 16alpha-OHE1 is a much more effective estrogen agonist on bone and liver than on reproductive tissues. These observations suggest that differences in the skeletal activities on 2-OHE1 and 16-alpha-OHE1 are responsible for the observed association between bone mass and circulating levels of these metabolites in postmenopausal women. We propose to test this hypothesis in ovary intact and OVX'd rats. The specific aims are to determine the dose response effects of 2-OHE1 and 16alpha-OHE1 on the expression of immediate response genes in bone and other estrogen target tissues; and establish the long-term effects of the estrone metabolites on bone architecture, turnover and strength. The proposed research will characterize the probably cellular mechanisms of action. The results of these studies are likely to be relevant to women because of the similarity between postmenopausal bone loss and OVX-induced bone loss in rats, as well as the previous success the rat model has enjoyed for predicting the response of the human skeleton to estrogen agonists and markers to predict the rate of postmenopausal bone loss; 2) manipulation of estrone metabolism by changes in diet or by pharmacological intervention may be a valuable tool for reducing bone loss; and 3) analogs of 16alpha-OHE1 may be useful for prevention and treatment of postmenopausal osteoporosis.

Project Title: ESTROGEN METABOLITES, RELATED GENES AND BREAST CANCER Principal Investigator & Institution: Shore, Roy E.; Professor of Medicine; Environmental Medicine; New York University School of Medicine 550 1St Ave New York, Ny 10016 Timing: Fiscal Year 2003; Project Start 15-APR-2003; Project End 31-MAR-2008 Summary: (provided by applicant): The NYU Women's Health Study (NYUWHS) cohort has played a leading role in elucidating the associations of estrogens and androgens with breast cancer, based on blood samples that were obtained prospectively in 1985-91 from over 14,000 healthy women of ages 35-65. We now team up with another cohort from the Northern Sweden Health and Disease Study in Umea to address questions about the roles of estrogen metabolites in breast cancer. The proposed grant period would extend the NYUWHS follow-up to about 19 years on average and would permit the accrual of nearly 1,000 incident breast cancer cases, while the Umea study will have over 600 cases. The follow-up and cancer case ascertainment rates have been high in both studies. The study will investigate how much levels of estrogen metabolites which can be both estrogenic and genotoxic - affect breast cancer risk, and the degree to which functional polymorphisms in estrogen metabolism genes are predictive of

estrogen metabolite levels and of breast cancer risk. We hypothesize that: Circulating levels of 16alpha-hydroxyestrone are positively associated with breast cancer risk, and the 2-hydroxyestrone to 16alpha-hydroxyestrone ratio is negatively associated with breast cancer; Genetic polymorphisms associated with altered activity of enzymes catalyzing 16alpha-hydroxylation (CYP3A4 and CYP3A5) and 4-hydroxylation (CYP1B1) are associated with breast cancer risk. Functional polymorphisms in the sulfotransferase and glucuronidase genes that diminish estrogen conjugation activity are associated with increased breast cancer risk. Over the last five years, the NYUWHS cohort has been the basis for investigations, with a series of collaborators, of numerous risk factors for various cancers (breast, colorectal, endometrial, ovarian) e.g., IGF-I and its binding proteins; organochlorines; serum carotenoids, phytoestrogens, folate and homocysteine; polymorphisms in luteinizing hormone and DNA repair genes. The availability of serum specimens, DNA, and lifestyle and dietary data collected prospectively, combined with the extended followup and increasing numbers of cancers, will allow the study to continue to foster the investigation of various biological risk factors for a range of cancers.

Project Title: EXPLORING MICROBIAL DIVERSITY FOR NOVEL NATURAL PRODUCTS Principal Investigator & Institution: Olson, Julie B.; Biological Sciences; University of Alabama in Tuscaloosa Tuscaloosa, Al 35487 Timing: Fiscal Year 2004; Project Start 01-JAN-2004; Project End 31-DEC-2006 Summary: (provided by applicant): The combination of the discovery, development, and exploitation of antibiotics was one of the most significant advances in medicine in the 20th century. Virtually all current antibiotics with clinical utility were identified during the so-called 'golden' period of discovery between the 1940's and 1960's and their implementation produced impressive reductions in the burden of disease caused by bacterial infections. Unfortunately, the widespread emergence of acquired resistance to antibiotics in bacteria over the last three decades now constitutes a serious threat to global public health. Thus, there is an important demand for the discovery and development of new classes of antibiotics to add our current arsenal and an urgent need for new drug discovery strategies. Natural products have historically been the single most productive source of drug leads, including antibiotics, yet screening of these secondary metabolites has recently fallen out of favor. For microbial-produced natural products, this is largely the result of the extremely high (99%) rediscovery rate, which occurs as a result of isolation, and testing of the same organisms again and again. This high rediscovery rate supports recent work suggesting that less than 1% of microbial diversity has been cultured and studied experimentally, and that the remaining 99% is not readily amenable to laboratory cultivation. Using this generally accepted theme as a starting point, novel media, media supplements, and cultivation conditions will be utilized to isolate microorganisms from a variety of natural, under-explored environments in Alabama. Microbial cultivations will be combined with fermentation and genetic screening to identify organisms that are capable of producing secondary metabolites. These studies are aimed at increasing our understanding of the problems associated with the isolation of microorganisms from natural environments and of the conditions required to increase production of secondary metabolites. The specific aims of the proposed project include: 1) to determine what approaches are necessary to increase the percentage of microorganisms isolated from natural environments; 2) to determine what growth factors/additions/manipulations will initiate production of

secondary metabolites in fermentation broths; and 3) to determine which organisms possess biosynthetic pathways for the production of potentially useful secondary metabolites. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: GENETIC POLYMORPHISMS IN THE EPOXYGENASE PATHWAY IN HYPERTENSION Principal Investigator & Institution: Dreisbach, Albert W.; Tulane University of Louisiana New Orleans, La New Orleans, La 70112 Timing: Fiscal Year 2002; Project Start 20-SEP-2002; Project End 31-AUG-2007 Summary: Vasoactive arachidonic acid metabolites of the cytochrome P450 (CYP) epoxygenase pathway, the epoxides, have been implicated in animal and human studies of hypertension. The epoxide 11-12 epieicosatrienoic acid (11,12-EET), the putative endothelium derived hyperpolarizing factor (EDHF)is formed by the enzymes CYP2C9, CYP2C8, and converted to its corresponding dihydroxy metabolite (DHET) by soluble epoxide hydrolase (sEH). CYP2C9 and CYP2C8 and sEH exhibit a high prevalence of genetic polymorphisms which may lead to altered levels of epoxides and reduced formation of EDRH in hypertensive patients. The perturbed vasoactive epoxide profile produced by genetic polymorphisms in this pathway may play a mechanistic role in a subgroup of patients with hypertension. Specific Aim 1: We propose to determine the prevalence of CYP2C9fC8 and sEH polymorphisms in hypertensive populations including both African Americans and Caucasians and compare these to the prevalence of these polymorphisms in race matched healthy control subjects. Specific Aim 2: We will also measure levels of EETs and DHETs in plasma and urine of patients with hypertension compared to race matched healthy controls for the various genotypes of CYP2C8/C9 and sEH. Specific Aim 3: We will determine whether in vivo CYP2C9 activity as measured by plasma S/R warfarin ratio, correlates with plasma and urine concentrations of eicosanoid metabolites for the various CYP2C9 genotypes in these same groups. Specific Aim 4: We will determine brachial artery reactivity via ultrasound in each of these same genotypic subgroups in race matched hypertensives and controls. The results from these studies will lead to new insights into the role of polymorphisms of the P450 epoxygenase system in cardiovascular regulation. The studies may demonstrate a role of these polymorphisms in some hypertensive populations, but in any case will provide increased understanding of the role of EETs and DHETs in vascular reactivity and blood pressure regulation.

Project Title: HCG ISOFORM MARKERS OF TROPHOBLASTIC MALIGNANCIES Principal Investigator & Institution: Birken, Steven; Senior Research Scientist; Obstetrics and Gynecology; Columbia University Health Sciences Po Box 49 New York, Ny 10032 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2005 Summary: (provided by applicant): HCG is the main tumor marker for both gestational and non-gestational trophoblastic disease. After a pregnancy with partial or complete hydatidiform mole, some patients develop malignant gestational trophoblastic disease. Patients may display unexplained elevation of circulating hCG with no evidence of clinical disease and are treated solely because of their hCG marker. Other patients under treatment develop resistance to therapy or relapse as detected by the hCG marker. We propose to assess the utility of several new immunoassays for hCG isoforms, recently developed in our laboratory, as improved hCG-related tumor markers. New markers

may help to identify the subpopulation of women who will require chemotherapy from those who will undergo spontaneous remission after a premalignant molar pregnancy. The new markers may also improve therapeutic care for both gestational and nongestational trophoblastic disease patients, including testicular cancers. These markers are based on four differentiating immunoassay systems to: 1.carbohydrate-related variants of hCG. 2. "nicked" forms of hCG. 3. isoforms both "nicked" and hyperglycosylated. 4. hCG and hLH beta core fragments. Most of these hCG isoforms have been shown to be structurally altered in malignancies but no assay measurement systems existed previously to quantify these isoforms. The hCG isoforms produced by healthy individuals (from pituitary) must be clearly differentiated from those isoforms produced by malignant tissues. The detection of carbohydrate-variant hCG isoforms are based on the antibody B152 (developed to choriocarcinoma-secreted hCG isoforms) which detects a differentially O-glycosylated form of hCG produced very early in pregnancy as well as in various malignancies. HCG-secreting cancers have also been reported to produce "nicked" hCG isoforms with peptide bond cleavages within the beta subunit. These will be measured by assay system (B151) in conjunction with a rapid chromatographic procedure. Choriocarcinoma and other trophoblastic cancers produce isoforms, which are both "nicked", and hyperglycosylated. These are detected by a B151 capture B152 detection assay. Systems to specifically measure urinary hCG and urinary hLH metabolites have also been developed so that hCG-related metabolites can be distinguished from normal hLH metabolites in postmenopausal women. Structural analyses will be performed to correlate isoform structures with assay measurements. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: HUMAN METABOLISM OF ANTI-ABUSE MEDICATIONS Principal Investigator & Institution: Moody, David E.; Associate Director; Pharmacology and Toxicology; University of Utah Salt Lake City, Ut 84102 Timing: Fiscal Year 2002; Project Start 01-AUG-1997; Project End 31-JUL-2006 Summary: (provided by applicant): Buprenorphine is a partial mu agonist under consideration by the FDA for use in opioid substitution therapy. It will join methadone and I-alpha-acetylmethadol (LAAM) as medications available at treatment centers. Buprenorphine is also being considered for private physician dispersal; which will greatly expand access to substitution therapy. All three of these drugs are cytochrome P450 (P450) 3A4 substrates. Drug interactions are a major cause of serious adverse drug effects and P450 3A4 is a major site of drug interactions. Many known drug interactions with methadone are due to its metabolism by P450 3A4. The proposal funded during the last period (R01 DA 10100-02) tested the hypothesis that the 3A4 inhibitor, ketoconazole, would inhibit the metabolism of LAAM to its more active metabolites, norLAAM and dinorLAAM, and thereby diminish its therapeutic effect. Data from that study demonstrate both in vitro and in vivo evidence of significant drug interactions providing support for this hypothesis. Since buprenorphine is nearing market launch, and few studies exist on its potential for serious drug interactions, we now hypothesize that determination of enzymes involved in the in vitro hepatic metabolism of buprenorphine will allow prediction of in vivo drug interactions of clinical significance. While testing this hypothesis, the fact that buprenorphine and its metabolite, norbuprenorphine, are extensively glucuronidated, and preliminary data that suggest other metabolites are produced by P450s must be taken into consideration. Therefore, to test this hypothesis we will: 1) extend our current liquid chromatographic-tandem mass spectrometric (LC-MSMS) method for buprenorphine and norbuprenorphine to include their glururonides; 2) use LC-MSMS to identify metabolites of buprenorphine generated

in human liver microsomes (HLM) and cDNA-expressed P450s; 3) determine the quantitative involvement of specific P450s in these pathways using kinetic analyses, specific inhibitors, specific antibodies and correlational analysis in HILM and cDNAexpressed P450s; determine the qualitative involvement of specific UDP-glucuronosyl transferases (UGTs) using HILM and cDNA-expressed UGTs; and 4) determine the in vitro induction of buprenorphine phase I and phase II metabolism in primary cultures of human hepatocytes. We anticipate these studies will provide the evidence to support clinical studies to more thoroughly test our hypothesis. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: IDENTIFICATION OF BIOACTIVE CRANBERRY METABOLITES Principal Investigator & Institution: Howell, Amy B.; Center for Blueberry and Cranberry Research; Rutgers the St Univ of Nj New Brunswick Asb Iii New Brunswick, Nj 08901 Timing: Fiscal Year 2004; Project Start 05-JAN-2004; Project End 31-DEC-2005 Summary: (provided by applicant): Cranberries have been clinically studied to assess their potential role in prevention of urinary tract infections. The results have been generally favorable, but many of the studies have been criticized for design flaws. One vital component at issue is participant adherence to study dosage, which has been particularly difficult to assess due to the lack of a reliable compliance marker. A quantifiable urinary metabolite(s) would be an ideal compliance marker for clinical trials, as the level could be associated with a biologically effective dosage of cranberry. Proanthocyanidins have been identified as the potential active compounds in cranberry, preventing the in vitro adhesion of P-fimbriated uropathogenic bacteria to uroepithelial cells, and producing an anti-adhesion effect in mouse urine following ingestion. However, the proanthocyanidin urinary metabolites have never been elucidated. The objectives of this proposal are to utilize bioassay-directed fractionation to isolate and identify the molecular structures of the active urinary metabolites and to determine the scope of the bacterial anti-adhesive properties of these metabolites. The long-term goal is to identify and quantify the levels of the active urinary metabolites so they can be utilized as markers for measuring compliance in clinical research. Urine will be collected over time from swine that have been fed defined quantities of standardized cranberry powder. Bioassay-directed fractionation of urine will be performed to identify active compounds. Assays will measure the ability of the fractions and subsequent pure compounds to prevent the adhesion of P-fimbriated E. coli. The structures of the active compounds will be identified by a range of spectroscopic techniques, including HPLC/API MS, LC/MS/MS, NMR and MALDI/TOF. The scope of activity of the metabolites will be measured by testing their anti-adhesion ability against a range of uropathogenic E. coli bacteria with known virulence factors. This will establish their utility for use as a broad-spectrum marker for measuring compliance to cranberry protocols. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

35
studies. Many of these studies have characterized factors that contribute to genderspecific pharmacodynamic differences in response to painful stimuli and alteration of the response with opioid analgesics. However pharmacokinetic factors, which may also contribute to this difference, have not been studied to the same detail. There are many reports identifying endogenous and exogenous compounds that interact with morphine by altering its metabolism, but understanding the resulting impact on analgesia is complicated by temporal delays in the pharmacokinetic effects. Using a computercontrolled, pharmacokinetically driven infusion of morphine, we have developed a study method for assessing the interaction of a parent drug with its active metabolites that takes advantage of the temporal lag that occurs in metabolite formation. In this exploratory R21 proposal, we will use pharmacokinetics to fix the concentration of one agonist agent, morphine, so that the impact of its active and inactive metabolites, whose concentrations we cannot control, can be rationally assessed. By conducting these studies in subjects where gonadal steroid hormones are held stable by oral contraceptives and in subjects where they cyclically fluctuate, we will begin to discern the difference between the pharmacokinetic and pharmacodynamic influences that gonadal steroid hormones have on analgesia produced by morphine. The results of this project will determine gender differences and important pharmacokinetic and pharmacodynamic covariates to aid in appropriate dosing strategies for the most widely prescribed opioid analgesic.

Project Title: IN VITRO GLYCORANDOMIZATION OF NATURAL PRODUCTS Principal Investigator & Institution: Thorson, Jon Scott.; Associate Professor; None; University of Wisconsin Madison 750 University Ave Madison, Wi 53706 Timing: Fiscal Year 2002; Project Start 03-JUN-2002; Project End 31-MAY-2007 Summary: (provided by applicant): Roughly 70 percent of current lead compounds in modern drug discovery derive directly from the natural products, many of which are glycosylated bacterial metabolites. While it is known that the sugar ligands of these pharmaceutically important metabolites often define their corresponding biological activity, efficient methods to alter these essential carbohydrate ligands are still lacking. This proposal outlines a stepwise approach to accomplish this goal while also providing invaluable mechanistic and structural information on two critical, but poorly understood, enzyme classes; namely, nucleotidylytransferases and glycosyltransferases. Specifically, the proposed studies are designed to exploit structure/function-based protein engineering to generate a promiscuous in vitro nucleotidylyltransferase/glycosyltransferase systems which will provide a library of potentially new bioactive metabolites. The model system selected includes the Salmonella rmlA-encoded alpha-D-glucose-1-phosphate thymidylyltansferase (Ep) and three glycosyltransferases, which act ponerthronolide B (EryBV, EryCIII and MegGT). Among the many advantages of the presented model, it has been shown that the MegGT-catalyzed addition of a single sugar (megosamine) to erthromycin leads to a metabolite (megalomicin) with remarkably different biological activity. Thus, the selected model promises varied biological activity from metabolites anticipated from the proposed studies. The specific goals include: 1) structural and mechanistic studies on Ep3 EryBV, EryCIII and MegGT, 2) structure-based Ep engineering for the construction of nucleotide sugar libraries and 3) the use of this library, in conjunction with EryBV, EryCIII and MegGT, to generate libraries of glycosylated erythronolides with potentially new bioactivity.

Project Title: INVESTIGATION OF GLUTARIC ACIDEMIA TYPE I. Principal Investigator & Institution: Koeller, David M.; Pediatrics; Oregon Health & Science University Portland, or 972393098 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2005 Summary: (provided by applicant): Glutaric acidemia type I (GA-I) is an inherited disorder of amino acid metabolism, which in its usual form, causes a progressive extrapyramidal movement disorder and death during the first decade of life. We have recently generated a mouse model of GA-I via gene targeting in embryonic stem cells. The affected mice demonstrate many of the phenotypic features seen in GA-I patients. The goal of this proposal is to use this animal model to answer a fundamental question regarding the pathophysiology of GA-I. Specifically, is the neurologic damage the result of circulating levels of toxic metabolites, or due to the lack of glutaryl CoAdehydrogenase (GCDH) activity within individual neurons (i.e. is it a cell autonomous phenotype). The specific aim of this proposal is to test the hypothesis that expression of the GCDH cDNA in the liver of Gcdh 1" mice will normalize the circulating levels of toxic metabolites (glutaric and 3-OH glutaric acids), and prevent the development of the myelinopathy and motor deficits seen in these animals. The approach we will use is to express the Gcdh cDNA in the liver of Gcdh / animals using the albumin promoter. Current therapy of GA-I consists primarily of a protein-restricted diet, which is based on the assumption that minimizing the levels of glutaric and 3-OH glutaric acids is beneficial. The experiments in this proposal will directly test that assumption. If our hypothesis is correct, the subsequent development of therapies such as liver directed gene therapy and liver stem cell therapy could then begin. Alternatively, if it is determined that normalization of metabolite levels is insufficient to prevent neuropathology in GA-I, alternative approaches to therapy need to be developed.

Project Title: ION CONDUCTANCES IN THE RETINAL PIGMENT EPITHELIUM Principal Investigator & Institution: Hughes, Bret A.; Associate Professor; Ophthalmology and Visual Sciences; University of Michigan at Ann Arbor 3003 South State, Room 1040 Ann Arbor, Mi 481091274 Timing: Fiscal Year 2002; Project Start 01-JAN-1991; Project End 31-DEC-2004 Summary: The health and integrity of photoreceptors critically depend on the composition and volume of their extracellular microenvironment. Regulation of the ionic composition and volume of this so-called subretinal space is accomplished by the transport of ions, water, and metabolites across the retinal pigment epithelium (RPE), a monolayer of cells juxtaposed between the photoreceptor outer segments and the choroidal blood supply. RPE transport is the result of the coordinated activity of a diverse group of ion pumps, co-transporters , exchangers, and channels residing in the apical and basolateral membranes. With changes in retinal activity, chemical signals released by retinal cell diffuse too the RPE where transport is adjusted to compensate for alteration in the photoreceptor microenvironment. Disruption of these transport processes or their regulation may cause adverse changes in the subretinal space, contributing to retinal disease. These transport pathways are also responsible for maintaining the intracellular composition in the RPE cell, which, if disturbed, could adversely affect other key RPE functions such as vitamin A transport and metabolism. Our overall goal is to understand the mechanisms by which potassium (K+) channels participate in the regulation of the volume and ionic composition of the fluid in both the subretinal space and the RPE cytoplasm. The specific aims are: (1) To determine the

molecular basis for the inwardly rectifying K+ (Kir) conductance of the RPE; (2) To determine the mechanism underlying the regulation of the Kir channel by intracellular ATP; (3) To understand how the Kir channel is modulated by physiological changes in intracellular pH; and (4) To test the hypothesis that volume-induced activation of another K+ channel, an M-type K+ channel, is mediated by arachidonic acid metabolites. These aims will be pursued using a combination of molecular and electrophysiological techniques to investigate K+ channel structure, function, and regulation. The outcome of these studies will be a better understanding of how these critically important transport proteins operate in the RPE to maintain a healthy photoreceptor microenvironment.

This proposal provides the framework for the candidate's plans to develop a multidisciplinary translational approach to chemoprevention research. Better interventions are needed to prevent the high mortality of colon cancer. Linoleic acid (LA), a common dietary polyunsaturated fatty acid, can be convertted to arachidonic acid (AA) that can in turn form mitogenic metabolites [e.g. prostaglandin, E2 (PGE2) and leukotriene B4 (LTB4)]. LA is also the substrate for 15-lipoxygenase-1 (15lox-1) in forming 13-S-hydroxyoctadecadienoic (13-S-HODE). We have found that 15lox-1 and 13-S-HODE are reduced in human colon cancers and that 13-S-HODE induces apoptosis in transformed colonic cells. In normal cells, the enzyme delta 6-desaturase (d6-d) forms gamma- linolenic acid (GLA) to start the conversion of LA to AA. Many tumor cells lack d-6-d activity and die by GLA exposure. Some evidence suggests tumor cells convert LA to AA by an alternative pathway that requires delta 5-desaturase (d-5d). The hypothesis is that a shift in linoleic metabolism from producing pro- apoptosis products [13-S-HODE and (GLA)] to the formation of mitogenic metabolites of arachidonic acid (e.g. PGE2 and LTB4) significantly contributes to colonic carcinogenesis. The specific aims are 1) to determine the activity of the alternative conversion pathway in relation to the transformation and differentiation states of colonic cells in vitro; 2) to evaluate the association between the shift in LA metabolism and the progressive steps of human colonic carcinogenesis using a clinical observational study model(by measuring the activity of LA alternative pathway and levels of related enzymes and metabolites of LA and AA [e.g. 13-S-HODE, PGE2, LTB4, d-6-d, and 15lox-1] in colonic tissues from 3 patient groups [normal, polyp, and colon cancers]); 3) to evaluate the effects of ectopic d-6-d expression on apoptosis, differentiation, and LA metabolism in transformed colonic cells in vitro; 4) to evaluate the impact of selective d5-d inhibition on LA metabolism and the survival of transformed colonic cells in-vitro; and 5) to determine the effects of selective d-5-d inhibition on colon carcinogenesis in an established short-term assay in rats. This work will set the stage for future animals and clinical studies of LA alternative pathway modulation as means of colon cancer chemoprevention.

Project Title: LIPID MAPS Principal Investigator & Institution: Dennis, Edward A.; Chemistry and Biochemistry; University of California San Diego La Jolla, Ca 920930934 Timing: Fiscal Year 2003; Project Start 12-AUG-2003; Project End 31-JUL-2008 Summary: (provided by applicant): Lipids play a central role in cellular function and disease. The scope of lipid involvement in cellular function has only recently been recognized to extend well beyond its established roles in energy metabolism and membrane structure. Lipids are an extensive group of small, amphipathic molecules that are divided into a series of classes based on structure and their biosynthetic origins. Still, all of these compounds possess many similar chemical and physical properties. Because of these similarities, the metabolic pathways that deal with lipids are complex and intertwined. Developing an integrated metabolomic system capable of characterizing the global changes in lipid metabolites ("lipidomics") is a daunting task but one that it is important to undertake in light of the significant returns produced by the global approaches of genomics and proteomics. Our consortium has developed a Lipid Metabolites And Pathways Strategy, termed LIPID MAPS that applies a global integrated approach to the study of lipidomics. The specific aim of LIPID MAPS for this grant period is to develop the requisite technology and conduct an integrated research program that will establish lipidomics as a fully functioning research field. By employing a rigorously maintained set of common biological, biochemical, and analytical technologies in each of the consortium laboratories, and by using an extensive informatics infrastructure, we will be able to integrate and analyze the large amount of data that will be generated by this large scale collaborative project. We will be able to generate "road maps" that will define how all of the lipid components of a cell move through the complex lipidomic network from biosynthesis to removal, including their important roles as second messengers. All of this information will be shared with the entire research community and should greatly aid in the development of metabolomics for other systems. In addition, LIPID MAPS should also aid in drug development since lipids play critical roles in numerous diseases, including inflammatory processes, atherosclerosis, Alzheimer's disease, cancer and stroke. Despite the clear benefits that developing a lipidomics field would produce, no large scale national or international programs for such a study exist. We believe that the experimental technologies are now in hand for establishing the field of lipidomics and that LIPID MAPS represents a viable strategy for achieving this goal. This would lead to the integration of lipids into the general focus of 21st Century biology; namely, into a fully quantitative systems-level biology.

The importance of arachidonic acid (AA) and its metabolites in modulating vascular tone, cell growth, migration, proliferation and gene expression is well known. The rate determining step in the production of eicosanoids is the release of AA by intracellular phospholipases A2 (PLA2). Accordingly, a detailed understanding of the types and

39
modes of regulation of vascular cell intracellular PLA2S are necessary to gain insight into the critical signaling mechanisms, which mediate atherosclerotic, and hypertensive disease states. We have identified the major vascular intracellular phospholipases as iPLA2B and 1PLA2Gamma The structure of iPLA2B is remarkable for: 1) the presence of ankyrin-like repeat domains in its N-terminus which likely modulate protein-protein interactions facilitating its intracellular sorting; and 2) a calmodulin binding domain in its C-terminus which regulates its activity. Accordingly, in Specific Aim 1 we will examine the functional role of the N-terminal ankyrin-like repeat domains in iPLA2B by identifying its protein binding partners. Next, we will explore the role of phosphorylation of the calmodulin binding domain to elucidate the role of protein kinases in regulating iPLA2B activity. Finally, the role of proteolytic activation of iPLA2B activity by caspase-3 and calpain-mediated cleavage will be examined. In Specific Aim 2, we will generate smooth muscle cell (SMC) specific overexpressors and mice null for IPLA2B and 1PLA2gamma in a SMC specific manner to determine the role of iPLA2s in vascular SMC tone, proliferation and migration. In Specific Aim 3, we will explore the newly identified role of AA as a modulator of endothelial cell (EC) nitric oxide production and the roles of Akt mediated activation of eNOS and iPLA2B in NO production. Finally, by exploiting chiral mechanism-based inhibitors of iPLA2B and iPLA27 we have developed, we will examine the role of intracellular phospholipases in EC responses to cyclic mechanical force. Alterations in the release of AA, generation of eicosanoid metabolites, lipid composition and cytoskeletal organization during changes in shear stress and mechanical stretch will be examined. Collectively, these studies represent a targeted, multidisciplinary approach to elucidate the roles of intracellular phospholipases in the vascular biology of the hypertensive and atherosclerotic disease states.

Project Title: LUMINAL LIPID EXPOSURE, GENETICS AND COLON CANCER RISK Principal Investigator & Institution: Kato, Ikuko; Pathology; Wayne State University 656 W. Kirby Detroit, Mi 48202 Timing: Fiscal Year 2002; Project Start 05-AUG-2002; Project End 31-JUL-2007 Summary: (provided by applicant): The long-term goal of the proposed study is to provide the scientific basis for public health strategies to reduce incidence of and mortality from colorectal cancer. Several lines of evidence suggest that a high fat diet increases the risk of colorectal cancer. While ecologic studies and earlier case-control studies demonstrated a strong association with high fat intake, the results from cohort studies and recent case-control studies have rather been inconsistent. These discrepancies may indicate some genetic susceptibility that modify the effects of a high fat diet. One of the major mechanistic bases for the roles of fat in colorectal carcinogenesis is intracolonic exposure to potentially carcinogenic substances which are generated from lipid and its metabolites with fecal bacterial activities. In this context fat absorption may play a key role in determining the effects of a high fat diet on colorectal cancer risk via modifying the levels of luminal exposure to potentially carcinogenic metabolites. Recently, two common genetic polymorphisms (FABP2 and Apo E) that affect intestinal fat absorption and bile acid secretion have been reported and associated with risks of cardiovascular diseases, diabetes and dementia. We hypothesize that individuals with genotypes for lower intestinal absorption, which results in more intracolonic exposure to potentially carcinogenic substances, have a higher risk of developing colorectal cancer in relation to a high fat diet. To test this hypothesis, we
40
Metabolites
propose to conduct a population-based case-control study in Metropolitan Detroit taking an advantage of the SEER Cancer Registry. We plan to interview 2000 cases and 2000 controls for their usual diet to estimate fat and other nutrient intake and collect blood or buccal cell specimens for genotyping assays. Specific aims of the study are (1) To determine whether the genotype, FABP2 A54, Apo E2/E3 or a combination of these, is associated with risk of colorectal cancer; (2) To determine whether the effect of a high fat diet on colorectal cancer risk is more pronounced in the subjects with these genotypes; and (3) To determine if the above interactions are modified by intake of other dietary components, such as fiber, calcium and iron, which affect luminal lipid metabolism. The results from the proposed study would provide useful information for effective dietary modification in primary prevention for colorectal cancer. In addition, accumulated dietary data and biological specimens will serve as an important resource for future research on other nutrient-gene interactions.

Project Title: MECHANISMS OF CARDIOVASCULAR COMPLICATIONS IN AIDS Principal Investigator & Institution: Agrawal, Krishna C.; Regents Professor and Chairperson; Pharmacology; Tulane University of Louisiana New Orleans, La New Orleans, La 70112 Timing: Fiscal Year 2002; Project Start 08-FEB-2000; Project End 31-JAN-2004 Summary: The primary long term goal of the proposed research is to investigate the mechanisms responsible for cardiovascular complications from cocaine abuse in AIDS patients. Serious cardiovascular complications due to cocaine abuse are well known; however, the molecular mechanisms have not been delineated. Cytokines play a significant role in the normal regulation of the function of endothelial cells and cardiac myocytes. There is growing evidence that the Tat protein of HIV- l can alter cellular gene expression and signal transduction pathways and can induce the formation of cytokines such as TNFalpha, and IL-1beta. Preliminary data demonstrate that TNFalpha can compromise cardiovascular function which is exacerbated in the presence of cocaine. We will therefore test the hypothesis that a combination of Tat and the cytokines (TNFalpha and IL- 1beta) with cocaine and its metabolites can produce cardiovascular complications in AIDS patients, by investigating the following specific aims: (l) to determine the effects of cocaine and its major metabolites in modulating the Ca2+, Na+ and K+ currents in isolated human cardiac myocytes in the presence and absence of TNFalpha or IL-1beta; (2) to investigate the modulatory effects of Tat protein and/or the inflammatory cytokines in the presence or absence of cocaine on integrin expression and integrin mediated events, i.e., endothelial cell migration and leucocyte adhesion to endothelial cells; (3) to assess the cardiovascular complications in mice acutely or chronically treated with cocaine and/or TNFalpha by monitoring the changes in: (a) systemic vascular resistance measured by systemic arterial pressure and cardiac output, (b) pulmonary vascular resistance determined by monitoring pulmonary arterial pressure and cardiac output, and (c) left ventricular contractility by measuring changes and the rate of change in the left ventricular pressure; and (4) to determine the role of Tat protein in modulating cardiovascular function. The tat transgenic and TNFalpha receptor knockout mouse models will be used to test the various parameters indicated under specific aim #3. The proposed studies will provide an in-depth understanding of the molecular mechanisms that may be responsible for the cocaine-induced cardiovascular complications in the presence of HIV infection. The unifying theme of the proposal is to define the role of Tat and the inflammatory cytokines in modulating the cocaine induced cardiotoxic effects that have been observed in patients with AIDS.

Project Title: MECHANISMS OF INHIBITORY DRUG INTERACTIONS Principal Investigator & Institution: Kunze, Kent L.; University of Washington Grant & Contract Services Seattle, Wa 98105 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2008 Summary: The long-term objective of the research described in this grant proposal is to better understand metabolism-based drug-drug interactions that are underpredicted from in vitro data. This is important because underprediction of effect has negative consequences for drug therapy and the development of new drugs. It is also important because these outliers represent a significant fraction of clinically relevant drug-drug interactions. An in-depth understanding of why predictions fail should improve predictive efforts. The interactions we propose to study are drawn from the larger class of interactions that appear to arise as the result concentrative cell uptake and/or metabolites of the interactant drug. Predictive quality is degraded because the magnitude of the inhibition depends not only on the concentration of the interactant drug at the active site, but also on the activity of the enzymes involved in converting the drug to the proximate inhibitory metabolite as well as the mechanism of metabolite inhibition. The first section of this proposal investigates two potent inhibitors of P450catalyzed drug metabolism, fluvoxamine and itraconazole, who's in vivo effects are 10to 100- fold higher than predicted. Fluvoxamine causes potent and differential inhibition of at least 4 important human P450' s in vivo. Aims 1-3 will identify the sources of the underprediction for each enzyme by examining the importance of concentrative uptake as well as direct inhibitory effects of fluvoxamine, itraconazole and their major metabolites on enzyme activities in microsomal preparations and human hepatocytes. The finding that time dependent, persistent inhibition of CYP3A4 activity by itraconazole is observed in microsomes and intestinal cells further suggests that itraconazole is a mechanism-based inhibitor of this important enzyme. Aim 4 will assess if other factors, such as concentrative uptake, are required to fully explain the effect of itraconazole and, if so, to identify them. The second section of the proposal addresses the propensity of alkylamine containing drugs to elicit irreversible inhibition of enzyme activity via formation of MI complexes in vivo and in vitro. This process requires that the alkylamine undergo as many as 4 rounds of oxidation to the corresponding Cnitroso metabolite prior to the inhibitory event. This very complex type of inhibition has not been fully characterized and a deeper understanding of the underlying mechanisms is critical for meaningful and reproducible in vitro-in vivo predictions of inhibitory effect. Aims 5 and 6 of this proposal set out to fully describe the kinetics of the system and evaluate the limits and advantages of a less complex empirical approach.

Metabolites
Plasma and tissue levels of tea polyphenols and their metabolites in animals and humans have been determined. In this project the applicant and colleagues plan to further elucidate the mechanisms of action and identify the active components involved with the following specific aims: 1. To elucidate the mechanisms of inhibition of carcinogenesis by tea in the NNK-induced lung carcinogenesis model in A/J mice and in relevant cell lines. The applicant and colleagues will study the inhibition of cell proliferation and tumor promotion by tea and tea constituents, and relate the activity to pertinent signal transduction pathways (such as MAP-kinases and AP-1 activation) in short and long term animal experiments. In-depth mechanistic studies in cell lines, on the inhibition of AP-1 and NFkB and the upstream of protein kinase cascade, will complement the animal studies and provide basic understanding of the action of tea polyphenols in general. 2. To determine the blood, urine, and tissue levels of tea polyphenols and their metabolites in rodents and humans under different experimental conditions and to understand the factors influencing these levels. Improved methods will be developed to include the analysis of many newly identified metabolites in pharmacokinetic studies. The blood and tissue levels of these compounds will serve as a reference for evaluating the mechanisms of anti-carcinogenesis and for comparing results in mice and humans. 3. To synthesize and determine the biological activities of the metabolites identified in Aim 2 in cell lines and animal models. The applicant and colleagues will address key issues concerning the bioavailability and bioactivities of Omethyl, glucuronide, and sulfate derivatives and two ring-fission metabolites of tea catechins.

Project Title: METABOLIC REGULATION OF MUSCLE BLOOD FLOW Principal Investigator & Institution: Hester, Robert L.; Physiology and Biophysics; University of Mississippi Medical Center 2500 N State St Jackson, Ms 39216 Timing: Fiscal Year 2002; Project Start 01-JUL-2001; Project End 31-MAY-2005 Summary: The blood flow to the peripheral circulation is regulated to maintain a balance between the delivery of nutrients and the metabolic demands of the tissue. Blood flow increases to a metabolically active tissue. This increased blood flow is the result of an increase in arteriolar diameter of terminal arterioles and larger upstream vessels. The terminal arterioles appear to determine distribution of flow while the upstream or "feed" vessels are more important in regulating total tissue flow. With an increase in metabolism there is the release of vasoactive metabolites from the tissue. Although vasoactive metabolites are known to affect the diameters of terminal arterioles the mechanisms by which metabolic factors regulate the diameter of upstream arterioles is uncertain. Recent studies from our lab and others have indicated an important role for the venular-arteriolar diffusion of vasoactive substances. The studies outlined in this proposal will test the following working hypothesis. In response to mismatches in blood flow and tissue metabolism, decreases in PO2 and/or increases in PCO2 and H+ are directly or indirectly sensed by the venular endothelial cells, resulting in the release of vasoactive metabolites of arachidonic acid which regulate the tone of adjacent arterioles. The proposed studies will test this hypothesis utilizing recently developed in situ microcirculatory techniques in which we are able to selectively remove the venular endothelium and assess the impact on blood flow regulation. The proposed studies will test two specific hypotheses: 1) The venular endothelium releases a metabolite of arachidonic acid that diffuses from the venule to the arteriole to cause an arteriolar dilation in response to an increase in tissue metabolic rate. 2) The venular endothelium responds to hypoxia, hypercapnia, and acidosis, directly, or indirectly to

initiate the release of one or more vasoactive factors from the venular endothelial cells. These studies should provide new and important information relevant to our understanding the importance of venular-arteriolar diffusion of endothelial derived factors in the regulation of blood flow.

Project Title: MIDARP AT HAMPTON UNIVERSITY Principal Investigator & Institution: Mclean, Hugh M.; Pharmaceutical Sciences; Hampton University Administration Bldg., Room 100 Hampton, Va 23668 Timing: Fiscal Year 2003; Project Start 15-MAR-2003; Project End 31-JAN-2008 Summary: (provided by applicant): The proposed MIDARP Program is envisioned to be the vehicle by which biomedical research in the substance abuse arena is initiated on the campus of Hampton University. The underlying goal of the program is the unbridled development of a vigorous and sustainable biomedical research program on substance abuse. This goal will be realized via a series of planned activities that are designed to enhance the research culture by augmenting the biomedical research infrastructure, by creating faculty development programs that facilitate the training of minority faculty members and foster interdisciplinary collaboration between the School of Pharmacy and the Departments of Biology, Chemistry and Psychology and to facilitate the training of graduate and undergraduate minority students in the biomedical sciences, particularly in substance abuse research. Furthermore, the proposal seeks to elucidate the underlying biochemical mechanisms associated with the neurotoxicity occasioned by 3,4-methylenedioxy-methamphetamine ("Ecstasy," MDMA). Toward this end, five research projects have been proposed: 1. Synthesis of potential metabolites and antagonists of MDMA. 2. Induction of apoptosis in neuritic cells innervated by serotonergic and dopaminergic neurons, by metabolites of MDMA. 3. In Vitro study of the metabolism of MDMA using human hepatocytes 4. Interactions between MDMA metabolites and dopamine and serotonin transporters. 5. The impact of MDMA metabolites on a variety of brain regions and processes in rats. It is anticipated that the results garnered from the planned activities will significantly enhance the existing body of knowledge on the mechanisms involved in the deleterious effects of MDMA.

Project Title: MITOCHONDRIAL METABOLITES TO TREAT PARKINSON'S DISEASE Principal Investigator & Institution: Ames, Bruce N.; Professor; Children's Hospital & Res Ctr at Oakland Research Center at Oakland Oakland, Ca 946091809 Timing: Fiscal Year 2004; Project Start 01-FEB-2004; Project End 31-JAN-2006 Summary: Mitochondrial decay due to oxidation is an important contributor to Parkinson's disease (PD) and other neurodegenerative diseases of aging. We have previously shown that mitochondrial decay in old rats can be ameliorated by feeding them the normal mitochondrial metabolites R-alpha-lipoic acid (LA) and acetyl-Lcarnitine (ALCAR), which inhibited oxidative damage and restored much of the mitochondrial structure and function in old animals. There is evidence that some mitochondrial metabolites may protect against PD. For example, coenzyme Q10 (CoQ) has been shown to protect against PD in clinical trials in humans; and ALCAR has been shown to protect against 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced toxicity, a PD mimic in monkeys. These metabolites protect by restoring mitochondrial antioxidants and function. We hypothesize that a mixture of mitochondrial

antioxidants/metabolites, CoQ, ALCAR and LA, could be optimized to be more effective than any single compound in preventing or treating PD. We will test our hypothesis using behavioral, biochemical, and immunohistochemical techniques on two models of PD: the chronic rotenone-exposed SK-N-MC human neuroblastoma cell model and the chronic rotenone-treated rat model. This project on PD is a new direction for our work on preventing mitochondrial decay and could lead to an effective and cost efficient prevention /therapy for PD.

Project Title: MODIFIERS OF CARCINOGENESIS--ENVIRONMENTAL PAH MIXTURES Principal Investigator & Institution: Baird, William M.; Director, Environmental Health Sciences; Environ & Molecular Toxicology; Oregon State University Corvallis, or 973391086 Timing: Fiscal Year 2002; Project Start 01-JUN-1980; Project End 31-MAR-2006 Summary: (provided by applicant): Humans are exposed to polycyclic aromatic hydrocarbons (PAH) in complex environmental mixtures and this exposure is linked to human cancer. Determination of the total levels of PAH-DNA adducts formed by complex mixtures is insufficient to provide the information necessary to assess human risk, because specific PAH metabolites differ greatly in carcinogenic potency. The hypothesis of the proposed studies is that by assessment of how two major classes of carcinogenic PAH are activated within complex mixtures, it will be possible to predict the potential of that mixture to affect activation of carcinogenic PAH present within that mixture and allow rapid estimation of the relative carcinogenic potency of complex mixtures. This hypothesis will be evaluated by examining the effect of environmental PAH mixtures on both PAH-DNA adduct formation and PAH-induced tumor induction in mouse skin by accomplishing four specific aims: 1. To extend our recent studies on the effect of environmental PAH mixtures on the metabolic activation and DNA binding of representative examples of the two major classes of carcinogenic PAH in mouse epidermis. We will compare our recent results from a standard mixture of PAH extracted from coal tar, SRM 1597, to two extracts derived from urban dust, SAM 1649 and from diesel exhaust (SRM 1650) obtained from the NIST. In order to determine how this type of environmental PAH mixture affects the metabolic activation of carcinogenic PAH, we will conduct PAH-DNA binding and tumor initiation-promotion studies in mouse epidermis. 2. To study the DNA-binding effect of complex PAH mixtures in human cells in culture. These studies will utilize MCF-7 human mammary carcinoma cell line and human MCF-10A human mammary carcinoma cell line which we have previously characterized with respect to their ability to metabolically activate individual carcinogenic PAH including B[a]P and DB[a,l]P to DNA binding metabolites. These studies will help us to relate the effects of complex PAH mixtures on DNA binding, tumor initiation and enzyme activation in mouse skin to how these mixtures affect carcinogen activation in humans. 3. To evaluate the carcinogenic potency of the above complex environmental PAH mixtures, as well as the effect of these mixtures on the carcinogenic activity of DB[a,l]P and B[a]P in tumor initiation-promotion assays in Sencar mice. 4. To determine the mechanism by which this complex PAH mixture affects activation of hindered bay-region and unhindered bay-region carcinogenic PAH through studies of the effect of complex PAH mixtures on CYP enzymes present in mouse skin. The proposed studies will determine whether the analysis of PAH-DNA adducts formed in mouse skin will provide a rapid approach for assessment of the relative carcinogenic potential of complex environmental mixtures of PAH. This will aid

Principal Investigator & Institution: Andrade, Joseph D.; Professor; Bioengineering; University of Utah Salt Lake City, Ut 84102 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JUL-2004 Summary: (provided by applicant): The investigators propose to develop microdevices for the specific chemical analysis of multiple metabolites in small sample volumes of biological fluids. The specificity and sensitivity is provided by specific reactions that couple analytes to bioluminescent-based enzyme reactions and produce light proportional to the analyte concentration. Bioluminescent analytical assays, in a miniaturized and stable format, can measure sub-microMolar concentrations in microliter sample volumes. The goal of the first phase (R21) is to engineer microfluidic structures, develop enzyme packaging and stabilization techniques, and optimize optical detection systems in order to measure two model analyte solutions (galactose and lactate) using bioluminescent reactions. The goal of the second phase (R33) is to implement other bioluminescent assays in the microfluidic detection system, develop specific diagnostic panels, utilize practical biofluid samples and enhance analytical accuracy and precision. The proposed Micro-Analytical System (microAS) will be convenient to operate in point-of-care (POC) and home environments. It will likely evolve to measure up to 100 different metabolites in the submicroMolar to milliMolar range from one 1-100 microL biofluid sample, and include customized comprehensive diagnostic panels for basic research, clinical research, and for personal disease and health management. These systems would provide rapid results, facilitate patient empowerment, and reduce health care costs. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: NEW ISOPHOSPHORAMIDE MUSTARD PRODRUGS Principal Investigator & Institution: Farquhar, David; Professor of Medicinal Chemistry and Pha; Experimental Therapeutics; University of Texas Md Anderson Can Ctr Cancer Center Houston, Tx 77030 Timing: Fiscal Year 2002; Project Start 03-JAN-2001; Project End 31-DEC-2005 Summary: Ifosfamide, an oxazaphosphorine with broad-spectrum clinical activity, is a key component of many front-line protocols for the treatment of both solid tumors and hematologic malignancies. Ifosfamide is not active in its own right; it requires P-450mediated oxidative metabolism in the liver to express cytotoxicity. Despite its broadspectrum activity, ifosfamide has several major shortcomings that limit its utility. Prominent among these is organ-specific toxicities, particularly, urotoxicity, nephrotoxicity and neurotoxicity. These toxicities, which are associated with the 'unwanted metabolites' of ifosfamide, principally acrolein and chloroacetaldehyde, seriously limit optimal drug administration. A second shortcoming of ifosfamide is drug resistance. Although several resistance mechanisms have been identified, elevated aldehyde dehydrogenase (ALDH) levels plays a prominent role in many murine and human tumor cell lines. A further clinical limitation of ifosfamide is that it can not be used for regional chemotherapy because of the need for hepatic activation. The goal of this proposal is to develop new prodrugs of isophosphoramide mustard (IPM), the

Metabolites
active metabolite of ifosfamide, that will avoid many of the toxicities caused by the 'unwanted metabolites' of ifosfamide. In this application, two new classes of IPM prodrugs that do not require oxidative activation are proposed. The new analogs proposed may be enzymatically convert to IPM under biological conditions. Accordingly, the new analogs should not cause many of the organ toxicities that have limited the clinical application of ifosfamide. The proposed prodrugs do not generate aldehyde intermediates, and therefore, are not susceptible to ALDH-mediated detoxification. Finally, since the prodrugs are activated in all tissues, they could be useful for regional chemotherapy as well as for the systemic management of patients with cancer. The principal investigator proposes to synthesize a number of prodrugs and study their (a) biotransformations in biologic tissues, (b) cytotoxicities against tumor cell and drug-resistant variants, (c) antitumor activities against experimental tumors and human tumor xenografts in mice, (d) organ toxicities in the mouse, and (e) antitumor efficacy compared with IPM and melphalan when administered by limb perfusion in a rat sarcoma tumor model.

Project Title: NEW METHODS FOR EVALUATING CHOLINERGIC TOXICITY Principal Investigator & Institution: Kirchhoff, Jon R.; Chemistry; University of Toledo 2801 W Bancroft St Toledo, Oh 43606 Timing: Fiscal Year 2003; Project Start 01-AUG-1998; Project End 31-JAN-2006 Summary: (provided by applicant): Cholinergic degradation has been linked to cholinergic disorders such as Alzheimer's dementia. Direct quantitation of the changes in concentrations of neurochemical marker compounds associated with neurocompromising events is a challenging task. Here, we will develop especially sensitive methodology to directly measure the changes in these neurochemical markers in response to selective cholinergic degradation. We have prepared 6hydroxycatecholine, a cholinomimetic analogue of 6-hydroxydopamine, and a number of related catechol-based chemical agents in a series for the purpose of defining conditions for the introduction of selective cholinergic presynaptic lesions in the brain. Selective cholinotoxic events will be investigated in vitro with synaptosomal preparations to establish the selectivity and relative neurotoxicity of each catechol-based chemical agent. Subsequent in vivo studies will be conducted by microdialysis sampling in cannulated rat brain to monitor the near real-time changes that occur in a living system. Conditions for the application of selective neurocompromising agents will be sought to maximize the changes in levels of choline and acetylcholine, while at the same time minimize the changes in catecholamine and tryptophan neurotransmitters relative to controls. Analytical methods based on capillary electrophoresis with microelectrochemical detection have been developed to selectively and sensitively monitor changes of trace levels of neurotransmitters and their metabolites. Capillary electrophoresis techniques permit efficient separation of mu l to nL samples of species based on their electrophoretic mobility, while electrochemical detection with specially designed microelectrode devices allow for additional selectivity and sensitive detection at the trace level. This strategy will allow sequential and time-resolved monitoring of the catechol-based chemical agents and their metabolites uptake efflux when coupled with microdialysis of tissues surrounding specific brain regions compromised with the chemical agents. The methodology will define the temporal and concentrationdependent acute and chronic selective compromise of cholinergic presynaptic sites by 6hydroxycatecholine and related quaternary ammonium catechol-based redox-affinity reagents. Thus, new methodologies to follow the chemical events in cholinotoxic states

A significant portion of breast cancer incidence in the U.S. is related to environmental factors and lifestyle, including diet. An example of a class of environmental mammary carcinogens is the nitropolynuclear aromatic hydrocarbons (NO2-PAH). The National Agency for Research on Cancer listed some NO2-PAH as possibly carcinogenic to humans. However, the actual risk associated with human exposure to NO2-PAH has not been clearly defined. In order to evaluate risks, we focused our efforts on understanding the mechanistic basis for tumor induction by 6nitrochrysene (6-NC) and mono-nitropyrene (mono-NP) isomers (1-, 2- and 4-NP). Studies proposed in the present application are a logical extension of our findings. Accordingly, we formulated the following hypotheses and the Specific Aims to test them. (1) We hypothesize that 1,2-dihydroxy- 1,2-dihydro-6-nitrochrysene (l,2-DHD-6NC) or 1,2-dihydroxy-1,2-dihydroxy-6-aminochrysene (1,2-DHD-6-AC) is the proximate mammary carcinogen and 1,2-dihydroxy-1,2-dihydro-6-hydroxylamino-chrysene (1,2DHD-6-NHOH) is the ultimate carcinogenic form. To test our hypothesis, we will carry out the following: (a) synthesis of DNA adducts derived from 1,2-DHA-6-NHOH, (b) synthesis of ample materials of metabolites derived from 6-NC and comparison of their relative potency as mammary carcinogens by intramammary administration in rats, (c) determine the type and frequency of mutations in the p53 gene in rat mammary tumors. (2) We have shown that NO2-PAH derived DNA adduct formation is necessary but is not sufficient for carcinogenesis. Clearly, there are gaps in our understanding of the role of DNA adducts in mammary carcinogenesis. Thus, we will determine the relationships between: (a) the nature and levels of DNA adducts, (b) mutation frequency and spectra and (c) mammary carcinogenicity induced by 6-NC using rats harboring the lacI reporter gene. Our hypothesis is that the major DNA adduct derived from l,2-DHD-6NHOH is responsible for the type and frequency of mutations in both the lacI gene and in the p53 gene. (3) To translate our ongoing studies of NO2-PAH in rodents, we propose to pursue similar studies in cultured human mammary tissues. We propose to employ normal (MCF-1OA) and cancer cell lines (MCF-7) to determine: (a) the metabolic capacity of the target organ (human breast tissues) and (b) the form of P450 isozymes involved in the activation of these carcinogens. The proposed study will also provide an experimental approach to the identification of relevant DNA adducts detected in humans; toward this end a pilot study will be initiated to determine the possible presence of NO2-PAH-derived DNA adducts in human breast tissues. (4) The hypothesis to be tested here is that certain covalent modification of genomic DNA by ultimate carcinogenic metabolites derived from 6-NC and mono-NP represents a type of cellular damage that can be responsible for an increased expression of the tumor suppressor protein p53.

AND
Principal Investigator & Institution: Rao, Gadiparthi N.; Associate Professor; Medicine; University of Tennessee Health Sci Ctr Memphis, Tn 38163 Timing: Fiscal Year 2004; Project Start 01-APR-2004; Project End 31-MAR-2008 Summary: (provided by applicant): Inflammation that follows tissue injury is believed to be important in the initiation and progression of various diseases including, atherosclerosis, cancer, and retinopathy. Phospholipase A2s (PLA2s), a group of enzymes that breakdown phospholipids generating arachidonic acid and lysophospholipids have been implicated in inflammation. One of the major events underlying the progression of atherosclerosis is angiogenesis. Endothelial cell (EC) migration and proliferation are critical events in angiogenesis. Emerging evidence suggests that PLA2, arachidonic acid and its eicosanoid metabolites play a role in the regulation of cell migration, proliferation, and apoptosis. In addition, recent investigations using nonsteroidal anti-inflammatory drugs reveal a potential role for eicosanoids in angiogenesis. Based on this knowledge, we hypothesize that eicosanoids, particularly the lipoxygenase-monooxygenase metabolites of arachidonic acid, play an important role in angiogenesis and thereby influence the pathogenesis of atherosclerosis. To test the role of eicosanoids in angiogenesis we will address the following four specific aims: 1. To identify eicosanoids produced in human microvascular endothelial cells (HMVEC) and determine their effects on angiogenesis using in vitro and in vivo models. 2. To determine the effects of angiogenic eicosanoids on HMVEC migration and proliferation. 3. To test the role of the Jak/STAT and PI3K/Akt pathways in angiogenic eicosanoid-induced HMVEC migration and proliferation. 4. To identify the effector molecules of eicosanoid-induced angiogenesis and study the mechanisms underlying their regulation of expression in HMVEC and vascular smooth muscle cells. The results of this proposal will provide novel information on the identification of specific angiogenic eicosanoids and on elucidation of the underlying mechanisms by which these lipid molecules stimulate angiogenesis. Such knowledge, in turn, could be useful in developing therapeutics in the prevention of progression of diseases such as atherosclerosis.

Principal Investigator & Institution: Liu, Yiming; Associate Professor; Chemistry; Jackson State University Jackson, Ms 39217 Timing: Fiscal Year 2003; Project Start 01-FEB-2003; Project End 31-JAN-2006 Summary: (provided by applicant): Occurrence and Neurotoxicity of Tetrahydroisoquinolines The goal of this research is to identify and quantify certain MPTP-like tetrahydroisoquinoline(TIQ) enantiomers in rat brain. Further, the neurotoxicity of these TIQ enantiomers and the major metabolites will be assessed. The chirality of TIQ's neurotoxicity has been observed. For example, the two enantiomers of 6,7-dihydroxy-1, 2-dimethyl-1,2, 3, 4 -tetrahydroisoquinoline (N-methyl-salsolinol) exhibit different neurotoxicological properties: the (R)-enantiomer induces Parkinsonism in rats, but the (S)-enantiomer does not. However, the in-vivo formation and metabolism of these enantiomeric neurotoxins remain largely unknown. To carry out these studies, simultaneous quantifications of the stereoisomers at trace levels are needed. However, suitable analytical methodology is lacking. To obtain the analytical

49
capability, we plan to modify the chiral GC-MS method that we have developed for the determination of salsolinol enantiomers, and also to develop a chiral method based on capillary electrochromatography -mass spectroscopy (CEC-MS). Experiments will include: a). simultaneous determination of dopamine and TIQ enantiomers including (R)-/(S)-salsolinol and N-methyl-(R)-/(S)-salsolinol in rat brain; b). quantitative studies of salsolinol metabolism using 13C labeled salsolinol enantiomers (i.e. [1,m-13C2]salsolinol); c) studies of the effects of chemical stimuli on the biosynthesis and metabolism; and d) assessment of the neurotoxicity of individual enantiomers of certain TIQs and their metabolites to rats. Our hypothesis is that racemization of the neurotoxic (R)-enantiomers of endogenous salsolinol and N-methylsalsolinol is a major pathway leading to detoxification in a healthy nervous system, and the racemization can be hindered by some chemical species such as alcohol. By studying the in-vivo enantiomeric biosynthesis, metabolism, and the neurotoxicity of MPTP-like TIQ neurotoxins, this research will contribute to our understanding of the chirality of TIQ neurotoxicity and the pathogenesis of Parkinson's disease.

Project Title: ONTOGENY OF DRUG BIOACTIVATION AND IDIOSYNCRATIC ADRS Principal Investigator & Institution: Leeder, James S.; Chief; Children's Mercy Hosp (Kansas City, Mo) 2401 Gillham Rd Kansas City, Mo 64108 Timing: Fiscal Year 2003; Project Start 01-JUN-2003; Project End 31-MAY-2008 Summary: (provided by applicant): Idiosyncratic adverse drug reactions (ADRs) are relatively rare, but potentially life-threatening events in which the determinants of susceptibility (largely unknown) are thought to be unique to the individual experiencing the adverse event. They can occur throughout the age spectrum but tend to be underemphasized in the pediatric literature yet children appear to be at increased risk for certain idiosyncratic ADRs such as valproate hepatotoxicity and cutaneous reactions to lamotrigine. An important step in the development of an idiosyncratic ADR appears to be biotransformation of the implicated drug to a chemically reactive metabolite ("bioactivation") that is capable of binding to cellular macromolecules and producing cell death directly or indirectly through initiation of an immune response. Although developmental changes in drug metabolizing enzymes such as the cytochromes P450 (CYPs) and glucuronosyl transferase (UGTs) have been characterized in children, little is known about the ontogeny of drug bioactivation as children grow and develop. Using biomarkers of acetaminophen (APAP), carbamazepine (CBZ) and valproic acid (VPA) bioactivation (and detoxification) in vivo, the goals of this research program are 1. to characterize the ontogeny of the drug bioactivation biomarkers in vivo and in vitro and 2. to identify the pharmacogenetic determinants of interindividual variability in APAP, CBZ and VPA biomarker expression during growth and development. To achieve these goals, two longitudinal "bioactivation" phenotyping studies will be conducted 1. in healthy children following a single test dose of APAP (15 mg/kg as Tylenol(r) alcoholfree solution, 80mg/0.8ml) and 2. in epileptic children routinely receiving CBZ or VPA for medical management of their disease involving NICHD PPRU sites in Kansas City, MO, Shreveport, LA, and Little Rock, AR. For each study, urine is collected overnight and analyzed for the presence of parent drug, "non-toxic" metabolites and conjugated l metabolites of candidate reactive metabolites. Specific urinary metabolite ratios will be used to determine the changes in reactive metabolic "burden" that occur during growth and development with specific reference to changes in CYP activities identified in longitudinal phenotyping studies currently underway. Paired DNA samples from the

Metabolites
extremes of the population distributions will be subjected to a concerted search by DNA sequencing and fragment analysis for single nucleotide polymorphisms (SNPs) that contribute to inter-individual variability in drug bioactivation. It is anticipated that the results of this program will allow critical periods of increased bioactivation and thus, potential vulnerability to idiosyncratic ADRs, to be identified for subsequent prospective investigations.

Project Title: PARAXANTHINE AND REPRODUCTIVE EFFECTS OF CAFFEINE Principal Investigator & Institution: Bracken, Michael B.; Professor and Head; Epidemiology and Public Health; Yale University 47 College Street, Suite 203 New Haven, Ct 065208047 Timing: Fiscal Year 2003; Project Start 01-AUG-1987; Project End 31-DEC-2004 Summary: (provided by applicant): Epidemiologic studies of antenatal caffeine consumption and adverse pregnancy outcomes have produced conflicting results. Most prior studies relied on self-reported caffeine consumption as a measure of caffeine exposure. However, caffeine metabolism and clearance greatly affect internal dose and, subsequently, fetal dose and consumption data may not provide a valid assessment of caffeine exposure. Because only 2.0% of caffeine is excreted as such in urine, there is considerable opportunity for error in estimating caffeine exposure using urinary caffeine levels. Paraxanthine, theophylline, and theobromine are primary metabolites of caffeine in humans and readily detected in body fluids. These metabolites may provide more reliable estimates of the biologically effective internal dose of caffeine. The specific aims of this application are: 1) to examine associations between intra-uterine growth retardation, preterm delivery, and birthweight with fetal caffeine exposure as estimated by cord blood serum paraxanthine; 2) to examine associations between serum paraxanthine, urinary caffeine, other metabolites, and self-reported caffeine intake; 3) to develop statistical models to determine the most precise predictive factors of caffeine exposure. We will link the analysis of serum caffeine metabolites with data previously collected on a large cohort of pregnant women (n=1775). Trained research assistants administered a baseline interview that included detailed questions on caffeine and decaffeinated beverage consumption, demographics, pregnancy history, medical history, tobacco and alcohol use, physical activity, use of nutritional supplements, and other reproductive risk factors. All women were asked to provide a urine sample at a baseline interview and cord blood was routinely collected and stored. In addition, women were randomly assigned to provide urine samples at 20, 28 or 36 weeks gestation. Medical records were abstracted to obtain information on obstetrical outcomes. The proposed work would conduct detailed biomarker analyses on samples collected from this cohort to provide a more complete understanding of effects of caffeine exposure on perinatal outcomes from a more accurate estimate of fetal exposure.

(CH). The studies are predicated on several novel findings we made during the previous grant period that include 1) orally administered CH is catabolized to DCA in children, 2) CH and DCA alter each other's metabolism, 3) DCA is biotransformed to glyoxylate, 4) DCA inhibits maleyacetoacetate isomerase (MAAI, also known as GST- zeta), a key enzyme in tyrosine metabolism 5) MAAI inhibition by DCA may cause accumulation of intermediates in the tyrosine catabolic pathway that may be responsible for the hepatotoxicity and neurotoxicity of DCA and 6) this inhibition may also be responsible for prolonging the elimination half-life of subsequent DCA doses. The following specific aims capitalize on these discoveries: (1): Determine the in vivo kinetics and biotransformation of CH in health adults and the influence of CH and DCA on each other's metabolism and toxicity. We will examine several postulates regarding CH and DCA biotransformation in humans. [13C] CH and DCA will be administered at environmentally (mug/kg) and clinically (mg/kg) relevant doses to adults and the kinetics and metabolism of these chemicals will be studied. (2): Quantify the effect of DCA and CH on tyrosine catabolism in children and adults by measuring the plasma and urinary concentrations on tyrosine, its metabolites and the heme precursor aminolevulinate. We will test hypotheses relevant t the perturbation of the tyrosine catabolic pathway by xenobiotics, via inhibition of MAAI. Such inhibition should lead to accumulation to accumulation of potentially hepatotoxic and neurotoxic metabolites. (3): Compare and contrast the in vivo human data with similar experiments performed in intact cells. We will address hypotheses concerning CH and DCA kinetics and biotransformation and their effects on tyrosine metabolism in animals. (4): Elucidate the molecular mechanisms of DCA and CH biotransformation, and their effects of biotransformation enzymes, using cellular and subcellular fractions of rat and human liver. We will test postulates regarding early molecular events involved in DCA biotransformation and their effects of biotransformation enzymes, using cellular and subcellular fractions of rat and human liver. We will test postulates regarding early molecular events involved in DCA biotransformation and the mechanism by which DNA influences MAAI activity.

Project Title: PREVENTION OF BREAST CANCER WITH SPHINGOLIPIDS Principal Investigator & Institution: Schmelz, Eva M.; Cancer Institute; Wayne State University 656 W. Kirby Detroit, Mi 48202 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2005 Summary: (provided by applicant): Breast cancer is the most common female cancer worldwide. Genetic defects clearly play a role in breast cancer etiology; however, epidemiological studies suggest a strong effect of the diet or components of the diet on the development and progression of breast cancer. The consumption of milk has been negatively correlated to the incidence of breast cancer. Sphingolipids are especially rich in milk and milk products. Sphingolipids regulate signaling pathways that have been shown to be dysregulated in cancer, mediating cell growth, differentiation, and cell death. Although the sphingolipid metabolites ceramide and sphingosine are toxic to cells at higher concentrations, no toxic side effects of even large amounts of dietary complex sphingolipids have been reported. This may be due to the limited digestion. It is these properties that make them ideal candidates for chemopreventive agents. We have shown earlier that dietary sphingolipids suppress early and late stages of chemically induced colon cancer. However, small amounts of the sphingolipid metabolites are transported into the body, and this may be sufficient to suppress breast tumor growth as suggested by epidemiological data. In the studies under this
52
Metabolites
application, we will use cell models for early and late stages of breast cancer, i.e., MCF10A, MCF10AT1 and DCIS cells, to characterize the response of normal, untransformed breast epithelial cells to exogenous sphingolipids. A comparison of the response of transformed breast epithelial cells will identify changes in signaling pathways mediating cell growth that may be responsible for the higher sensitivity of transformed cells to sphingolipids. Moreover, we will evaluate if non-toxic concentrations of sphingolipid metabolites can enhance the effects of conventional chemopreventive and chemotherapeutic agents. These studies will establish markers for sphingolipid efficacy in suppression of breast tumor growth that can be used in future in vivo studies. We also will be able to determine which combination of sphingolipid metabolites and chemotherapeutic agents is most promising in reducing cell growth and/or inducing apoptosis in tumor cells but do not affect normal cells. The results from these studies will provide the tools to conduct in vivo studies, and hopefully will lead to the development a concept of breast cancer chemoprevention with dietary sphingolipids as a non-toxic alternative to conventional treatment.

Project Title: PRIMAQUINE-INDUCED HEMOLYTIC ANEMIA Principal Investigator & Institution: Mc Millan, David C.; Pharmacology; Medical University of South Carolina P O Box 250854 Charleston, Sc 29425 Timing: Fiscal Year 2002; Project Start 01-JAN-2001; Project End 31-DEC-2004 Summary: (Adapted from the Applicant's Abstract): Malaria is recognized as the most widespread parasitic infection in humans. Primaquine has been a major antimalarial drug for over 40 years due to its unique effectiveness against exoerythrocytic forms of the parasite. Its therapeutic value has grown in recent years with the development of resistance to alternate antimalarial drugs such as chloroquine and because of its utility in the treatment of Pneumocystis carinii pneumonia in AIDS patients. However, primaquine therapy has been severely limited because of its capacity to induce methemoglobinemia and hemolytic anemia, particularly in patients with glucose-6phosphate dehydrogenase deficiency. It has long been known that the hemotoxicity of primaquine is due to the action of metabolites and not the parent compound. However, the toxic specie(s) have not been identified and little is known about the mechanism underlying red cell injury. In collaborative studies with individuals at Walter Reed, we have examined the hemotoxicity of known and putative phenolic metabolites of primaquine and have observed potent and direct-acting hemotoxicity. In other studies, we have synthesized 6-methoxy-8-hydroxylaminoquinoline (MAQ-NOH) and found that this metabolite was also a direct-acting hemotoxicant. We now propose to investigate the mechanism of red cell damage induced by these metabolites and examine their metabolic formation in vitro. The hypotheses under test in this proposal are: 1) that two pathways of oxidative damage, initiated by lipid peroxidation and protein thiol oxidation, occur in the red cell; and 2) that quinone/quinoneimine metabolites act via lipid peroxidation, whereas the N-hydroxy metabolite acts via protein thiol oxidation. Three aims are presented: 1) to characterize the hemolytic response and pattern of oxidative injury induced within red cells by each type of primaquine metabolite; 2) to elucidate the oxidative metabolism of primaquine in rat and human liver microsomes and hepatocytes, and identify GYP isoforms responsible for primaquine metabolism; and 3) to identify intracellular and external cell surface alterations that correlate with phagocytosis of primaquine metabolite-damaged red cells by cultured splenic macrophages.

Project Title: PROTECTION AGAINST BENZO{A} PYRENE TOXICITY BY OLTIPRAZ Principal Investigator & Institution: Ritter, Joseph K.; Associate Professor; Pharmacology and Toxicology; Virginia Commonwealth University Richmond, Va 232980568 Timing: Fiscal Year 2002; Project Start 01-APR-1996; Project End 31-MAY-2005 Summary: (Adopted from the Applicant's Abstract): Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental pollutants found in certain foods, cigarette smoke and combustion products of oil, coal, and gas. The prototype PAH, benzo[a}pyrene (B[a]P) is one of the most potent chemical carcinogens known in animal tumorigenesis assays. The level of hepatic glucuronidating activity towards benzo[a]pyrene phenols, quinols, and dihydrodiols, appears to represent a key risk factor underlying susceptibility to B[a]P's genotoxic effects. Evidence has been obtained that oltipraz (4-methyl-5-pyrazinyl- 1 ,2-dithiole-3-thione), an investigational cancer preventive drug, may act in part through induction of hepatic UDPglucuronosyltransferases (UGTs) with activity towards B[a]P metabolites. UGTs in the UGT1 family appear to be particularly critical. A previously identified UGT1 isoform, UGT1A7, appears highly active in the glucuronidation of B[a]P metabolites. Specific Aim 1 will directly compare the activity of recombinant UGT1A7 to other UGTIA isoforms to determine if any other of these forms are potentially relevant either in protection against B[a}P or in the response to oltipraz. The UGTs will be expressed in HEK293 cells and tested for activity in vitro against key metabolites of B[a]P and other carcinogenic PAHs. Specific Aim 2 will study whether the corresponding human UGT1A isozymes are also active. In addition, variation in human liver microsomal UGT activities towards B[a]P metabolites will be characterized in relation to expression of specific UGTIA subsets (UGTIAI, UGTIA3-.1A5, UGTIA6, and UGT1A7-lO). Specific Aim 3 will continue studies of the mechanisms controlling the hepatic expression of rat UGT1A6 and UGT1A7 by oltipraz and PAHs. To characterize possible species differences in regulation, a study will be performed to assess the responsiveness of human UGT1As in cultured human hepatocytes. Specific Aim 4 will develop novel in vivo approaches to assess the functional significance of UGT1A deficiency and replacement of UGTIA7 liver expression for B[a]P excretion and mutagenesis. To examine the influence of UGTIA deficiency and monitor B[a]P induced mutagenesis in a short term in vivo assay, a special strain of rat will be developed by crossing the Gunn rat onto the Big Blue lad transgenic F344 rat background. Replacement of UGT1A7 expression in liver will be achieved through the use of a recombinant adenovirus 5 engineered to express UGT1A7.

Project Title: REACTIVE METABOLITES AND DRUG TOXICITY Principal Investigator & Institution: Hanzlik, Robert P.; Professor; Medicinal Chemistry; University of Kansas Lawrence Youngberg Hall Lawrence, Ks 660457563 Timing: Fiscal Year 2002; Project Start 01-AUG-1978; Project End 31-MAR-2004 Summary: Many simple organic molecules containing phenyl substituents or benzene rings become cytotoxic upon biotransformation to reactive electrophilic metabolites. Prime examples include halothane, acetaminophen and bromobenzene (BB). Their hepatotoxicity is correlated with covalent binding of reactive metabolites to cellular proteins. As a start toward elucidating the biochemical mechanism(s) of their cytotoxicity we identified the structures of ten adducts of BB metabolites to protein-SH groups; most arose via quinone metabolites, but we also found that BB-3,4-oxide (BBO),
54
Metabolites
thought to be the primary "toxic" metabolite of BB, alkylates histidine and lysine as well as cysteine residues of rat liver proteins. Key questions concerning the mechanism of cell injury by reactive metabolites include the identity of the proteins they target and the functional consequences of their covalent modification. We recently identified several rat liver proteins targeted by BB metabolites. One was a nonspecific esterase also known to be a target for metabolites of halothane and molinate. Another, surprisingly, was epoxide hydrolase, which is supposed to detoxify BBO. To address the mechanism of BB-induced cytotoxicity it is essential to expand this list by identifying other liver proteins targeted by BB metabolites. In doing so we will emphasize mitochondrial proteins but will continue to explore cytosolic and microsomal proteins. To facilitate recognition of BBO adducts, we raised antibodies to p-bromophenylcysteine and demonstrated their utility for western blotting; we will now develop antibodies to p-bromophenyl-histidine and p-bromophenyl-lysine as well. These antibodies, coupled with [C14]-BB, will give us a broad and powerful means for finding and identifying those proteins of greatest toxicological interest. Very little is known about the chemistry and consequences of protein adduction by reactive metabolites. Thus we will elucidate in detail the specific site(s), metabolite(s) and linkage(s) involved in adduct formation for select BB target proteins. For those target proteins which are enzymes, we will evaluate the effect of adduction on catalytic activity to assess its potential contribution to cell injury. Comparing the proteins modified by bromobenzene to those modified by other small bioactivated toxins may reveal the existence, or the lack of, a "common pathway" for chemically-induced cytotoxic responses.

Project Title: REGULATING CEREBRAL MICROCIRCULATION BY ASTROCYTES Principal Investigator & Institution: Harder, David R.; Director; Physiology; Medical College of Wisconsin Po Box26509 Milwaukee, Wi 532260509 Timing: Fiscal Year 2002; Project Start 01-APR-1985; Project End 31-MAR-2005 Summary: The brain relies almost exclusively on oxidative metabolism to support neural activity and is therefore critically dependent upon adequate blood flow. The hypotheses to be tested in this competing renewal are that astrocytes sense neural activity via spillover of excitatory transmitters and release dilatory metabolites to adjacent capillaries, thereby increasing distribution of blood flow to active neurons, and secondarily, that epoxygenases metabolites of astrocytes are mitogenic and endothelial cells. We have isolated, cloned and sequenced a cytochrome P450 gene of the 2C family of epoxygenases which catalyzes formation of vasodilatory epoxyeicosatrienoic acids (EETs) from arachidonic acid (AA). EETs increase K+ channel activity to hyperpolarize and relax arteriolar smooth muscle, and are released from astrocytes stimulated by glutamate. Inhibition of EETs formation by site directed molecular or pharmacological mechanisms prevents increase in nutritive blood flow measured by laser-Doppler flowmetry. The specific aims of this grant are three-fold. (1) We will determine the ability of astrocyte-released EETs to inhibit normal autoregulatory mechanisms caused by vasoconstrictors, shunting blood flow by opposing the depolarization of cerebral arterioles at physiological pressures. Nitric oxide (NO) also hyperpolarizes arterial muscle by mechanisms which include increasing outward K+ current, thus may amplify the hyperpolarizing and dilator action of EETs; therefore, the additional contribution of NO to countering autoregulatory mechanisms in cerebral vessels will be examined. (2) To begin to investigate the cellular and ionic mechanisms behind EETs induced modulation of autoregulation, we will examine the capacity of astrocyte- produced EETs to modulate K+ and Ca2+ channel activity and [Ca2+]i in cerebrovascular smooth

55
muscle and endothelial cells. (3) Preliminary data show that EETs also initiate mitogenic activity of capillary endothelial cells and stimulate tube formation in co-culture with astrocytes, providing a mechanism to increase capillary endothelial cells and stimulate tube formation in co-culture with astrocytes, providing a mechanism to increase capillary density in areas of high neural activity. Therefore, the signal transduction cascade responsible for cellular growth by EETs increased from astrocytes will be examined by a combination of cellular, molecular, genetic and in vitro techniques to test the hypothesis set forth above. The physiological significance of these phenomenon cannot be over-stated. While many mechanisms are described involving formation of dilatory paracrine substances in the metabolic control of nutritive cerebral blood flow, we have gathered a wealth of data supporting a role for astrocytes and their ability to metabolize AA to vasoactive epoxides. Our investigations will provide vital new information defining mechanisms by which epoxygenase metabolites of astrocytes inhibit autoregulatory vasoconstriction of cerebral arteries.

Project Title: REGULATION OF PHOSPHOLIPASE A2 NUCLEAR TARGETING Principal Investigator & Institution: Leslie, Christina C.; Senior Faculty Member; National Jewish Medical & Res Ctr and Research Center Denver, Co 80206 Timing: Fiscal Year 2002; Project Start 01-JAN-1999; Project End 31-DEC-2003 Summary: Cytosolic phospholipase A2 (cPLA2) is a key regulatory enzyme that mediates agonist-induced arachidonic acid release. Arachidonic acid itself is an important intracellular regulator and can also be converted to a variety of potent lipid metabolites, the eicosanoids. This occurs through the lipoxygenase and cyclooxygenase pathways for the production of leukotrienes, and prostaglandins. These oxygenated metabolites of arachidonic acid play crucial roles in normal homeostasis and in mediating the inflammatory response. Intracellular levels of arachidonic acid are tightly controlled and cPLA2 is subject to complex mechanisms of activation that are poorly understood. cPLA2 is post-translationally regulated by phosphorylation and by levels of intracellular calcium. Agonist-induced serine phosphorylation of cPLA2 on Ser505 by mitogen activated protein kinase enhances cPLA2 activity. An increase in intracellular calcium triggers cPLA2 activation by inducing its translocation from cytosol to the nuclear envelope/endoplasmic reticulum (ER), where 5-lipoxygenase and cyclooxygenase are also localized. Calcium-induced binding of cPLA2 to membrane is mediated by the calcium-dependent phospholipid binding domain (CaLB or C2 domain) on the amino terminus of cPLA2. Although the role of the CaLB domain in membrane binding is established, the mechanisms involved in the specific targeting of cPLA2 to nuclear membrane/ER are not known, and their elucidation is the main objective of this proposal. The specific aims of the proposal include defining the role of the C2 domain and regions downstream of the C2 domain (including the plekstrin homology domain of cPLA2) in regulating nuclear targeting, and identifying proteins that bind cPLA2 and determining their role in regulating cPLA2 activity and translocation. Potential cPLA2 binding proteins have been identified using a biochemical approach and screening a phage display library. Domains of cPLA2 that are important in regulating nuclear targeting will be identified using site-directed mutagenesis. Effects of the mutations on agonist-induced arachidonic acid release and translocation of cPLA2 to the nucleus will be evaluated by expression in mammalian cells and in insect cells using baculovirus. Purified mutant constructs will also be evaluated for effects on enzymatic activity and lipid vesicle binding. Understanding the regulation of cPLA2 will provide greater insight into the signal transduction

mechanisms involved in lipid mediator production, and lead to potential methods for pharmacological modulation of the inflammatory process. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: REGULATION OF PROTEIN KINASE C AND CELL CYCLE BY PAH O-QUINONES AND ROS Principal Investigator & Institution: Kazanietz, Marcelo G.; Associate Professor; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 30-AUG-2002; Project End 31-JUL-2007 Summary: Protein kinase C (PKC) isozymes are a family of related serinethreonine kinases that play an important role in the control of cell proliferation, death and differentiation. PKC isozymes are the target for the phorbol esters and are implicated in the molecular mechanisms of tumor promotion. A main objective of this proposal is to evaluate whether PAH oquinones and the ROS they generate affect PKC activity and signaling events resulting in phenotypic consequences on cell growth. Our preliminary data shows that PKC isozymes are direct targets for PAH o-quinones, suggesting that these compounds have epigenetic effects that could explain why PAH may act as complete carcinogens. Our studies will assess effects of these PAH metabolites on PKC in vitro as well as in bronchoalveolar cells. In Aim#1 we will evaluate the effect of DMBA-3,4-dione, BA-3,4-dione and BP-7,8-dione, which correspond to Class I, II, and III o-quinones, respectively on the activity of individual PKC isozymes expressed in baculovirus. We will assess whether the o-quinones or the ROS they generate affect PKC kinase activity and cofactor-dependent binding of phorbol esters. In Aim#2 we will evaluate whether PAH o-quinones or ROS affect translocation of PKC and activate or inhibit PKC isozymes in cells. We will take advantage of AKR1A1 overexpressors to determine whether o-quinones or ROS generated intracellularly affect the phosphorylation of endogenous PKC substrates (myristoylated alanine-rich C kinase substrates) and PKC-mediated AP-1 activation. In Aim # 3 we have shown that the phorbol ester, phorbol-12- myristate-13-acetate (PMA), inhibits the proliferation of bronchoalveolar cells by causing G1 arrest. Individual PKC isozymes will be infected into bronchoalveolar cells to identify the isoform responsible for this PMA effect. We have shown that PAH o-quinones inhibit PKC in vitro and stimulate S phase entry in bronchoalveolar cells. Therefore we will test the hypothesis that PAH o-quinones or ROS dysregulate components of the cell cycle controlled by PKC. We will correlate increased progression through G1 phase with changes in the expression of G1 phase cyclins and cdk inhibitors and the consequences for cdk activity and Rb phosphorylation. Importantly our studies will determine the effects of individual PKC isozymes on the proliferation of human lung epithelial cells and whether PAH oquinones dysregulate PKC mediated control of the cell cycle. The Project is reliant on the Bioanalytical Core-B for quality control of PAH-metabolites and determining PAH oquinone concentrations in cell culture. The Project is reliant on Core-A for biostatistical analysis of the in vitro and in vivo effects of PAH o-quinones and ROS on PKC. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Timing: Fiscal Year 2004; Project Start 01-SEP-2000; Project End 31-AUG-2009 Summary: (provided by applicant): The National Resource for Accelerator Mass Spectrometry (AMS) was established in 1999 to enable biomedical researchers to accurately quantify very low levels of radioisotopes while exploring fundamental issues in biology. In this renewal, we will expand our present capabilities by developing methods to study biochemical pathways and cellular processes at the level of the single cell and small groups of cells, which will allow our collaborators to study the effect of aging in yeast. The Resource will also develop methods to quantify endogenous processes, such as protein and DNA oxidation in higher organisms. This will facilitate the study of inflammatory diseases ranging from atherosclerosis to neurodegenerative disorders to cancer. To further these goals, we will develop a sample presentation technology that will enable the analysis of much smaller samples than can be currently processed, as well as techniques for speciation of biomolecules in such samples. Throughout the tenure of the grant we will continue to provide a resource to the research community that will include service to investigators familiar with AMS, training of investigators in the technology and dissemination of the Resource. Towards these goals, our specific aims are to: 1.) Develop protocols for the online combustion of eluents from separatory instruments and couple the products to a gas accepting ion source to increase the sensitivity of AMS. 2.) Increase the value and information content of AMS measurements by quantitating isotope content in isolates of uniformly isotopelabeled systems or by quantitating derivatized biomarkers of modification or function on specific macromolecules. 3.) Provide quantitation of effector and effect in biological systems using multiple isotopic tracers within sampled materials. We will achieve this by developing a robust and higher throughput process for 3H sample preparation and by leveraging against other funded isotope measurements at the Center for Accelerator Mass Spectrometry (CAMS). 4.) Provide high throughput and precise quantitation for collaborative and service users. OVERALL CRITIQUE: This competitive renewal application for the Resource for Development of Biomedical Mass Spectrometry seeks to extend the applications of Accelerator Mass Spectrometry (AMS) for the study of biological systems. Three Core Technological R & D Projects focus on the development of improved sample processing and handling approaches and their application to problems in cell biology and biomarker analysis. These Core R & D Projects are coupled to a set of nine collaborative projects that provide biological motivations for extending the applications of AMS. Overall, this application proposes innovative approaches to significant biomedical problems to be performed by a highly accomplished team. It is clear that the Resource is very successfully developing AMS as an important new tool for the study of biological systems. Progress in the current research period has established a robust and viable national Resource and demonstrated important applications in toxicology and metabolism. The proposed technological R & D in this renewal application aims to broaden both the instrumentation capabilities and the sample preparation and analysis methods to extend AMS into new areas. This is a unique and significant technological Resource with significant outreach to the biomedical community. Presentations at the site visit clarified several technical issues raised in the application. The site visit gave the strong impression of a well integrated team of senior and more junior researchers who interact well with each other and with collaborators. The principal investigator (PI) and co-Investigator/Director are outstanding scientists and world leaders in the field of AMS, and their enthusiasm, as well as that of the team, was evident. Presentations by several collaborators were also very useful for emphasizing the biological impact of the technological R & D being proposed, as well as tight coupling between these collaborations and the Core Projects. Clear evidence of institutional support for AMS in general and this Resource, was
58
Metabolites
evident. In the preceding inaugural research period, the AMS Resource sought to demonstrate methods for the use of AMS in biomedical research, to expand their measurement capabilities and capacities, and to increase collaborative access to the instrument. The major biological applications for these Aims centered on the characterization of the metabolism of vitamins and environmental toxins. A major focus was the binding and metabolism of heterocyclic amines, performed via collaborations with several internal and external collaborators. AMS was used to study the metabolism of 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) in humans and rodents, and to identify plasma and urine biomarkers of PhIP exposure. This work, conducted in collaboration with NIH-funded researcher, Dr. James Felton (LLNL), has led to several publications. This work was expanded to aid the development of strategies for reducing the amount of DNA damage following exposure to PhIP in collaboration with Dr. Andrew Clifford (UC Davis). The metabolism of several other environmental toxins, including acrylamide, orthophenylphenol, benzene, aflatoxin, atrazine, and diisopropylfluorophosphate, were the subject of additional collaborations and publications. The micronutrients, folic acid and beta-carotene, were also studied in collaborative projects that took advantage of the unique ability of AMS to detect very low levels of metabolites in biological samples. Significant methodological developments targeting the problems of trace laboratory contaminants, post-labeling methods, and streamlined methods to convert organics species for AMS were also achieved during the current research period, and have enhanced the usefulness of AMS for routine analysis of biological samples. An active collaborative and service portfolio is serving to define the needs for new capabilities for the biomedical applications of AMS and providing instrument access to the biological community. Overall, progress during the current research period was viewed as excellent. In this competitive renewal proposal, the AMS group proposes three Core R & D Projects. The first Core Project aims to address issues associated with the sample spectrometer interface. For coupling to separations instruments, an online sample and combustion interface to a gas sputter ion source will be developed. The gas-accepting ion source has limitations with regard to maximum ion current compared to ion sources for solid samples, but will allow the continuous analysis of very small samples eluting from microbore separations devices. For higher resolution analysis, improved methods will be developed for converting gases to solids, especially for tritium analysis, which is a significant extension of the carbon analysis that was the subject of the initial research period. While specific details of the coupling approaches outlined in the proposal were somewhat vague, and the amount of potential sample carryover undetermined, the review committee had a high degree of confidence that these challenges would be successfully addressed by this team. The review committee was enthusiastic about this Core Project. In the second Core R & D Project, AMS will be applied to the quantitative analysis of trace isotope in single cells or ultimately, cell parts. The proposed approach involves Aims for the extensive labeling of yeast cells with 14C, the isolation of single cells or organelles, analysis of samples using HPLC-AMS, and analysis of samples using SPE-AMS. These Aims will be demonstrated by measuring the ratio of NAD and NADH in yeast cells to evaluate the role of caloric restriction of these metabolites and by evaluation of the asymmetric segregation of oxidized proteins in budding yeast cells. This was viewed as a highly innovative project with a very significant goal, the extension of AMS to single cell analysis. The review committee's enthusiasm was tempered by the presence of several technical scientific issues, including the consequences of heavy labeling with radioactive isotopes, especially for studies of oxidized proteins and uncertainties with the quantification of cell mass. A clear statement of a validation process, in the absence of preliminary data regarding resolution of these challenges, would have strengthened this project. While the rationale for the choice of a yeast cell biology problem as a simple

59
system was recognized by the committee, there was concern about the extensive effort required to answer fairly narrow biological questions. This project was seen as an innovative approach to a significant area but with these uncertainties, overall enthusiasm was moderate. The third Core R & D Project aims to develop methods to identify and monitor biomarkers of diseases based on modified DNA and proteins. The approach includes aims to develop methods for the pre-labeling and post-labeling of DNA and proteins and to demonstrate these via collaborative projects involving inflammatory diseases and ischemic reperfusion damage. This was viewed as a project with high significance, important goals, and very good collaborative interactions. The development of specific post-labeling strategies for analysis of DNA and protein oxidation products, with sensitivity that is orders of magnitude better than that currently available, was seen as particularly significant. The primary challenge will be to develop appropriate specificity, either through the labeling methods or the separation methods. There are clear issues with achieving specificity with post-labeling, although at the site visit, the team presented several encouraging approaches for achieving this specificity, especially for protein adducts. The detection of DNA adducts using enzymatic methods were seen as very dependent on the specificities of the enzymes used and, while promising data was presented at the site visit, there was some concern about the generality of the methods proposed. More information about alternative enzymes and their potential specificities would have alleviated these concerns. In view of the significant biological impact of this project, and the active involvement of biological collaborators, the review committee was enthusiastic about this project. Nine collaborative projects were presented to advance or test the technology being developed by the Resource. All represented important and interesting biological problems. Many clearly provided the required drivers for the Core Technological R & D, while for others this drive was not clear or absent, and these are more appropriately classified as service projects. Presentations at the site visit provided excellent examples of the intellectual contributions of the collaborators to the development and focus of the Core R & D Projects. Collaborative Project 1 (Purines and purine anti-metabolites in malaria; V Schramm) proposes to use 14C and 3H AMS to track the metabolism of purines in Plasmodium falciparum in order to understand metabolic pathways and to develop metabolic inhibitors. This is a very strong collaboration with an NIH investigator and a clear rationale for the use of AMS that will clearly drive the R & D of Core Project 1. Collaborative Project 2 (Neuronal turnover in the adult brain; J Friesen) aims to use 14C AMS and the bomb curve to estimate neuronal proliferation in adult brains. While a very interesting and important biological problem, it was not clear from the information provided in the application how this collaboration drives the core R & D and it was seen as a more appropriate service project. Collaborative Project 3 (Mechanisms of gene silencing using small interfering hybrids; L Dugan) proposes to use AMS to quantify the uptake of small inhibitory RNA-DNA hybrids by mammalian cells. Fluorescence and PCR-based methods to assess this have been unsuccessful. This logical application of cellular AMS, supported by LLNL internal funding, is tied to Core Project 2. Collaborative Project 4 (Quantification of osteoporosis therapeutics; H De Luca) will use tritium AMS to study the pharmacokinetics of vitamin D variants that may stimulate bone resorption. This collaboration supports Core Project 1, but will ultimately have a service-like nature. Collaborative Project 5 (Detection of ethylene oxide DNA adducts; K Brown) aims to use dual 14C and 3H labeling to simultaneously monitor endogenous and exogenous EtO DNA adduct formation. This was seen as a very strong collaboration that clearly drives Core Project 1 and addresses an important problem. Collaborative Project 6 (Phagocyte pathways for oxidative stress; J Heineke) aims to use AMS to measure protein oxidization products resulting from inflammation. The presentation given by Dr. Heineke highlighted the contribution of collaborators to the
60
Metabolites
development of Resource goals. This was seen as a very strong collaboration driving the biomarker Core Project 3. Collaborative Project 7 (Quantification of oxidized 8-oxo-2' deoxyguanine lesions in DNA; C Burrows) aims to quantify DNA adduct oxidation products and is tied to biomarker Core Project 3. While this project was discussed to some extent in the description of Core Project 3, few details were provided about this collaboration. Collaborative Project 8 (Quantification of reperfusion injury; D MochlyRosen) proposes to use AMS to assess protein oxidation as a marker of reperfusion injury. It also proposes to evaluate the effect of inhibitory peptides derived from protein kinase C (PKC) on tissue reperfusion damage. This project has both collaborative and service components, and is tied to Core Project 3. Collaborative Project 9 (Quantification of cysteine sulfenic acids; J Eiserich) aims to use AMS for the analysis of protein sulfenic acid labeling. This collaboration, which appears to be at a preliminary stage, supports Core Project 3, and will depend on the availability of specific post-labeling methods. The Service, Training, and Dissemination plans were seen as very strong, with clear plans in place for allocating responsibilities and monitoring these activities. Active dissemination through the recruitment of new collaborators was seen as especially useful. Clear procedures for prioritization handling of service activities were presented. Excellent performance in the current research period gave the review committee great confidence that these plans will be carried out. Enthusiasm was very high for these components. The organizational structure and administration was seen as very strong. The PI and coInvestigator/Director are outstanding senior scientists with excellent records of accomplishment. The addition and integration of several newer scientists was seen as clear evidence that the Investigators are positioning the Resource to address new types of biological problems. The external advisory committee appears strong and engaged. Plans to rotate membership to incorporate expertise in new areas were seen as sound. The service and training plans were very well thought out. The Resource management does an excellent job of obtaining and leveraging institutional support for both personnel and facilities. TECHNOLOGICAL RESEARCH AND DEVELOPMENT: CORE PROJECTS: Core Project 1: Sample Spectrometer Interface Development Priority Score: 151 While AMS at LLNL has been extremely successful at quantifying biological samples, further instrumental advances are required to examine smaller sample sizes and to take advantage of analytical separations. In addition, the previous research cycle of this Resource was focused primarily on 14C quantitation with minor effort directed at 3H quantitation. In this renewal period, the PI proposes to develop appropriate sources and sample preparation approaches to use a gas-accepting source with the existing AMS system to allow for increased throughput in 3H quantitation, capabilities for dual 3H and 14C quantitation, and potential for coupling to external separation methods.

Project Title: ROLE OF COX2 IN LUNG CANCER ANGIOGENESIS AND METASTASIS Principal Investigator & Institution: Johnson, David H.; Professor of Medical and Surgical Oncolo; Vanderbilt University 3319 West End Ave. Nashville, Tn 372036917 Timing: Fiscal Year 2002; Project Start 01-JAN-2002; Project End 31-DEC-2002 Summary: (provided by applicant): Upregulation of cyclooxygenase-2 (COX-2) has been shown to be an early event in colon carcinogenesis. Multiple lines of evidence suggest that COX-2 upregulation is also an early event in the development of non-small cell lung cancer (NSCLC). In humans, COX-2 expression is upregulated in about one-third of atypical adenomatous hyperplasias and carcinoma in situ specimens obtained from lung, and in 70 percent-90 percent of invasive adenocarcinomas of the lung. The
Studies
61
proportion of adenocarcinoma cells with increased COX-2 expression is much greater in lymph node metastases than in the corresponding primary tumors. Preclinical data indicate tumors with upregulation of COX-2 synthesize high levels of prostaglandin E2 (PGE2). High PGE2 levels are associated with increased production of proangiogenic factors and enhanced metastatic potential. These findings suggest that an increase in COX-2 expression may play a significant role in the development and growth of NSCLC and possibly with the acquisition of an invasive and metastatic phenotype. Specific inhibitors of COX-2 are now available and may prove useful in understanding the role of eicosanoids in lung cancer pathogenesis as well as in the management of established malignancies and possibly as chemopreventive agents. However, there are limited data on the function of tumor overexpression of COX-2 in lung cancer patients, and no data on whether selective inhibitors actually affect COX-2 activity within the targeted tumor in vivo. We propose to study the effects of specific inhibitors of COX-2 on COX-2 expression, serum VEGF levels and urinary metabolites of PGE2 in patients with lung cancer. Our results will serve as a prelude to clinical trials in which these agents are employed therapeutically. Our preliminary data suggest inhibitors of COX-2 rapidly reduce enzyme activity as determined by measurements of urinary metabolites of prostaglandin and assessment of enzyme activity within the tumor itself. These experiments will expand upon these preliminary results. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: SAME AND FOLATE DEFICIENCY IN ALCOHOLIC MIRCROPIGS Principal Investigator & Institution: Halsted, Charles H.; Professor; Internal Medicine; University of California Davis Sponsored Programs, 118 Everson Hall Davis, Ca 956165200 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2007 Summary: (provided by applicant): The overall hypothesis of the proposed research is that the pathogenesis of alcoholic liver disease (ALD) is regulated by changes in intrahepatic methionine metabolism that result from chronic ethanol consumption. Previously, we found that the combination of dietary ethanol and a folate deficient diet both maximized perturbations in methionine metabolism and accelerated the development of ALD in micropigs. The objective of the proposed research is to prove the hypothesis by demonstrating that the biochemical and histopathological features of ALD can be prevented or reversed by provision of supplemental S-adenosylmethionine (SAM) or folic acid to pigs maintained on chronic ethanol feeding with and without folate deficient diet. The first specific aim is to determine the efficacy and metabolic effects of intervention with SAM or folic acid in the prevention and treatment of ALD in micropigs. The second specific aim is to study the effects of abnormal methionine metabolism on known mediators and signal pathways of alcoholic liver injury. Micropigs will be fed diets with ethanol that are either folate sufficient or deficient and with or without supplemental SAM during development of liver injury, and with or without supplemental SAM or folic acid after development of alcoholic liver injury. Data collection will include methionine metabolites in plasma and liver, liver histopathology, markers of inflammation, necrosis, and apoptosis, products of lipid, protein, and DNA oxidation, antioxidant enzymes, and signal pathways of apoptosis. The data will be interpreted to confirm the role and establish potential mechanisms for abnormal methionine metabolism in the pathogenesis of ALD. While furthering understanding of interactions of methionine metabolites on pathways of liver injury, the project may establish novel approaches to the prevention and treatment of ALD.

Project Title: SCREENING HERBS FOR DRUG INTERACTIONS Principal Investigator & Institution: Markowitz, John S.; Associate Professor; Pharmaceutical Sciences; Medical University of South Carolina P O Box 250854 Charleston, Sc 29425 Timing: Fiscal Year 2002; Project Start 05-JUN-2001; Project End 31-MAY-2004 Summary: The use of herbal agents by the lay public and medical professionals has accelerated in the last decade. Additionally, there has been increasing interest by the NIH National Center for Complementary & Alternative Medicine (NCCAM) and others in the safety and efficacy of herbal medicines in the treatment of a variety of medical and psychiatric conditions. It has also become evident that herbal medications are being used concomitantly with conventional prescription and over-the-counter medications. However, the systematic evaluation of the potential of these agents to interact with conventional medications has been generally neglected. Compounding this problem is the fact that even single entity herbal products can contain a multitude of naturally occurring chemicals which serve as candidates for potential herb-drug interactions by inhibiting or inducing specific hepatic isozymes. Numerous reports document the importance of pharmacokinetic interactions involving inhibition or induction of the cytochrome P450 (CYP) enzyme system. Importantly, recent publications have documented that clinically significant herb-drug interactions can occur. Prominent examples include herb-induced reductions in plasma concentrations of the anti-HIV medication indinavir and the immunosuppressant cyclosporine by St. John's wort (Hypericum perforatum). In vitro screening studies are of limited value due to difficulties in approximating physiologic concentrations, assessing the influence of nonhepatic metabolism, and accounting for the contribution of active metabolites. However, based upon findings of the effects of concurrently administered herbs on the metabolism of enzyme specific probe drug substrates alprazolam (CYP 3A4) and dextromethorphan (CYP 2D6), the potential specificity and magnitude of CYP enzyme inhibition and/or induction can be determined in normal volunteers. In a preliminary study in human subjects using this validated probe drug technique assessing inhibitory effects only, the investigators found no effects of St. John's wort on CYP 3A4 or CYP 2D6. In the present proposal, the 10 most commonly used herbal products in the US will be systematically evaluated for inhibition of CYP 3A4 and 2136, and induction of CYP 3A4. Collectively, these enzyme systems are involved in the metabolism of approximately 80% of all marketed medications. A combination of probe drugs will be given to normal volunteers both in the absence and presence of herbal medications. The plasma and urine concentration of these agents and their respective metabolites will be determined in order to evaluate individual herbal products degree and specificity of enzyme inhibitory or inductive effects. This data will fill a void regarding the relative safety of combining specific herbal agents with conventional medications and will serve as the basis for further investigations of other isozymes and herb interactions. Further, the proposed studies will complement existing and future NCCAM studies of agents such as St. John's wort and Gingko biloba.

Summary: (provided by applicant): Induction of prostate cancer (PCa) cell apoptosis can be an effective approach for the chemoprevention and treatment of this disease because clinically PCa is often characterized by low cell proliferation rate and does not respond to standard anti-mitogenic chemotherapy. The goal of this project is to elucidate the biochemical and molecular pathways through which cancer chemopreventive agent selenium (Se) induces P53-dependent, caspase-mediated PCa apoptosis. We hypothesize that wild type P53 tumor suppressor protein and its Ser15 phosphorylation (Ser15P) are crucial determinants for inducing caspase-mediated apoptosis by genotoxic Se metabolites such as selenite and are not critical for apoptosis induced by the nongenotoxic methyl Se. We further hypothesize that selenite exposure induces superoxide generation and DNA strand breaks which trigger P53 Ser15P mediated by ATM and/or ATR protein kinases and signaling to caspase activation. Three specific aims will be accomplished. 1. To establish a causal relationship of selenite induction and/or ATR as the protein kinases for P53 Ser15P. 2. To critically test that caspase-mediated apoptosis by selenite is dependent on wild type P53 and its Ser15P and that apoptosis induced by methyl Se is P53-independent. 3. To delineate the signaling cascade(s) of selenite induction of caspase activation, especially the roles of the mitochondria intrinsic pathway and the death receptor extrinsic pathway. A variety of approaches including enzyme inhibitors, RNA interference of ATM/ATR and P53 and other genetic manipulations will be used. Accomplishing these aims will be crucial for charting a roadmap for studying how Se metabolites selectively bring about the demise of PCa cells depending on their P53 status. The mechanistic insights will help to guide the design of novel Se agents with better efficacy and tolerance and to interpret the results of PCa prevention trials with Se.

Project Title: STABLE ISOTOPE LABELED PROTEINS AND DRUG DISPOSITION Principal Investigator & Institution: Abramson, Fred P.; Professor; Pharmacology; George Washington University 2121 I St Nw Washington, Dc 20052 Timing: Fiscal Year 2002; Project Start 01-FEB-1999; Project End 31-JAN-2004 Summary: The 1990s has seen the arrival of many protein therapeutic drugs. In response to the increased availability and use of these macromolecular pharmacological agents, the FDA is moving its review of these products from the "biologicals" category into the "drugs" category. As such, increased emphasis on physiological disposition would be expected. Yet, suitable methods for studying protein drug disposition do not exist. Radioisotopes, bioassays, and immunoassays all present problems. In contrast, a new experimental approach developed in this laboratory promises more definitive results, especially in the area of metabolism. This approach uses uniformly stable-isotope labeled proteins as test species, separates biological fluids with HPLC, and quantifies stable- isotope enriched chromatographic peaks with Chemical Reaction Interface Mass Spectrometry (HPLC/CRIMS). Uniform labeling ensures that all metabolites of the protein can be detected. Such proteins can be generated by growing a suitable cell line in stable-isotope labeled medium. The three protein disposition studies proposed are: (1) the angiotensinogen cascade and the effect of a protease inhibitor on that cascade; (2) the intracellular proteolysis of fibroblast growth factor-1 (FGF-1); and (3) the kinetics and metabolism of insulin connecting peptide (C-peptide). The purpose of the first study is to demonstrate how the uniformly labeled protein + HPLC/CRIMS analysis provides a comprehensive survey of the consequences of an inhibitor of angiotensin converting enzyme (a dipeptidyl carboxypeptidase). In the FGF-1 experiments, the goals are to generate an unambiguous profile of the intracellular metabolites produced in NIH 3T3

cells, evaluate which of these peptide metabolites contribute to the activity of FGF-1, and identify the active species using electrospray mass spectrometry. Recently, Cpeptide was shown to lessen the vascular and neurological consequences in experimentally-diabetic rats. Because C-peptide has long been believed to be inactive, little information exists about its kinetics, and nothing is known about its metabolic fate. Overall, this work will show he capabilities of a new strategy by which a more accurate understanding of the fundamental pharmacology of an increasingly important class of drugs can be gained.

Project Title: TRANSFER OF METABOLITES THROUGH LENS GAP JUNCTIONS Principal Investigator & Institution: Goldberg, Gary S.; Physiology and Biophysics; State University New York Stony Brook Stony Brook, Ny 11794 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2006 Summary: (provided by applicant): Lens cells require gap junction proteins to communicate with each other and develop properly. In particular, connexin43 (Cx43), Cx46, and Cx5O are needed for normal lens development and function. Knockout or mutations of genes encoding these connexins cause cataracts in mice and humans, respectively. Cx43, Cx46, and Cx5O form channels with different permeability characteristics. We hypothesize that transjunctional molecules needed for lens development pass through lens gap junctions, and that cataracts can result from an inability of cells to share these signals. We propose to identify and compare the transfer of endogenous metabolites that pass through these channels. This new research program will introduce a particularly innovative technological approach to investigate the role of gap junctions in the lens. In Specific Aim 1 we will determine the single channel size, total conductance, and number of functional gap junction channels expressed by mammalian cells transfected with connexins that are expressed in the lens. This will be done by standard dual voltage-clamp whole-cell recording methods. In Specific Aim 2 we will identify, quantitate, and compare the transfer of endogenous metabolites that pass through channels formed by connexins expressed in the lens. This will be accomplished with a novel strategy to identify and quantitate the transfer of endogenous molecules that pass through gap junctions between cells within a given time frame. Measurement will be taken at several time points to measure and compare the rates of transfer of specific metabolites through gap junction channels formed by Cx43, Cx46, and Cx5O. These results will be combined with data obtained from Aim 1 to calculate the permselectivity of these gap junctions to metabolites on a per channel basis. We hypothesize that lens connexins form channels that display selective permeabilities to specific metabolites, and that this connexin permselectivity can not be predicted solely on the basis of size and charge of the permeant. We will begin to identify the permeability characteristics and actual transjunctional molecules that are responsible for lens development, transparency, and disease. This work should lead to a greater understanding, and, ultimately, treatments, of eye diseases that result from aberrant gap junctional communication.

Summary: (provided by applicant): St. Louis University has a critical mass of NIH funded investigators whose research would be enhanced substantially by the purchase of a TSQ Quantum triple quadrupole ESI-MS/Surveyor HPLC instrument bundle. To support the ongoing studies integrating genomics, proteomics and metabolomics at Saint Louis University we request funds to purchase this instrument from Thermo Finnigan. The proposed users have appointments in five different departments at the Health Sciences Center, and are involved in basic and applied research in the fields of gene regulation, lysosomal storage diseases, heart disease, renal disease, diabetes, retinal disease, pulmonary disease, drug abuse and pathogenic mycology. The rapid progress in genomics and proteomics has created new opportunities for understanding metabolic processes controlled by macromolecular complexes. Understanding these metabolic processes by identifying the diverse metabolites Produced under different physiological and pathophysiological conditions represents an important new field of biomedical research described as metabolomics. Research in this field should provide both important diagnostic strategies as well as therapeutic targets for the treatment of many diseases. Triple quadrupole electrospray ionization-mass spectrometry (ESI-MS) instrumentation with an HPLC interface is required for many metabolomic studies. The triple quadrupole is required for identification of metabolites since it can be used for collisionally induced dissociation (CID) of molecular ions which provides structurallyinformative spectra. Additionally, HPLC resolved metabolites infused into the ESI source provides both important chromatographic characterization of metabolites and ESI-MS analysis of metabolites which together are often critical for the identification of metabolites. A major deficit of the instrument facility at Saint Louis University Health Sciences Center is the lack of a triple quadrupole ESI-MS instrument. This requested instrumentation will remedy this deficit in our otherwise well-equipped facility. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: VITAMIN A (RETINOL) AND 4 OXORETINOL IN BREAST CANCER Principal Investigator & Institution: Gudas, Lorraine J.; Professor and Chair; Pharmacology; Weill Medical College of Cornell Univ New York, Ny 10021 Timing: Fiscal Year 2002; Project Start 01-APR-1998; Project End 31-JAN-2004 Summary: Retinoids, a group of compounds consisting of vitamin A (retinol) and its natural metabolites, have been shown in numerous experimental systems to act as cancer chemopreventive agents and cancer chemotherapeutic agents. While previous research has shown that retinoic acid (RA) is a very potent vitamin A metabolite which causes cell differentiation and inhibition of the growth of tumor cells, we have recently identified two new potent, bioactive vitamin A metabolites, 4-OHretinol and 4oxoretinol, in a number of cultured tumor cell lines. Although we first isolated these bioactive retinoids, 4- OHretinol and 4-oxoretinol, from a murine cell line (Achkar et al. (1996) PNAS 93:4879-4884), we have recently shown that estrogen receptor (ER) positive cultured human breast cancer cell lines such as MCF-7 can synthesize 4-OHretinol and 4-oxoretinol from retinol under certain culture conditions. In contrast, estrogen receptor negative breast cancer cells do not synthesize 4-OH-retinol and 4-oxoretinol from retinol. We have also recently shown that 4-oxoretinol is growth inhibitory for both ER positive and ER negative breast cancer lines, whereas RA is growth inhibitory in ER positive but not in ER negative breast tumor lines. In this proposal, we want to explore the activity of these new, bioactive retinol metabolites on normal human breast epithelial cells and on breast cancer cells: a) to determine more about the molecular mechanism by which 4-OHretinol and 4-oxoretinol can induce cell growth arrest, and b) to compare 4-oxoretinol with RA with respect to the regulation of gene expression. We

will assess whether or not 4- oxoretinol synergizes with RXR specific ligands, N-(4hydroxyphenyl) retinamide, interferon, TGFbeta, and/or tamoxifen with respect to the growth arrest of breast cancer cells and the regulation of gene expression. We also plan to characterize biochemically the enzyme(s) which converts retinol to 4-OHretinol and 4-oxoretinol, to clone the gene(s) for the enzyme(s), and to delineate its regulation in human breast cancer cells. Tetracycline inducible antisense RNA techniques will be employed to block the expression of this gene. Our proposed studies may lead to the use of 4-oxoretinol or related compounds in the prevention and/or treatment of human breast cancer.

Project Title: VOLUMETRIC MR MOLECULAR IMAGING OF BRAIN Principal Investigator & Institution: Maudsley, Andrew A.; Professor; Radiology; University of Miami-Medical Box 248293 Coral Gables, Fl 33124 Timing: Fiscal Year 2002; Project Start 20-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): This project will develop neuroimaging methods for acquisition and mapping of brain metabolites by short-TE proton MR Spectroscopic Imaging (MRSI). This measurement is typically complicated by spectral overlap, lineshape distortions, lipid contamination, and subject motion, and these effects limit the accuracy of the metabolite measurement as well as the number of metabolites that can potentially be detected. These limitations will be addressed by using high-speed acquisition methods to obtain multiple volumetric MRSI data sets that are each encoded with varying spectral information. Data analysis methods will be developed using multidimensional parametric modeling analysis approaches, to provide improved discrimination of overlapping spectral components. In addition, higher spatial resolution acquisition, field inhomogeneity correction, and motion compensation methods will be simultaneously included to obtain data with improved spatial response and spectral quality. Acquisition sequences will be implemented that exploit both spin relaxation and evolution parameters, and evaluated in normal subjects. Parameters will be optimized using numerical simulation techniques to maximize spectrat discrimination and signal to noise ratios, while also limiting the number of independent spectral measurements required. These same numerical methods will also be used to provide the prior information required for the spectral analysis procedures. The developed methods will be applied to mapping all metabolites observed using short-TE proton MR spectroscopy in normal human brain, and a 3D image database of metabolite levels will be generated. This will make use of spatial transformation and normalization procedures obtained through IRPG interactions with researchers at the MRS Unit, San Francisco (PIG. Matson). This development will establish the range and variance of normal metabolite profiles and provide valuable comparative data for numerous clinical investigations that use short-TE 1H MRS.

Project Title: WHOLE CELL NMR STUDIES OF MYCOBACTERIA Principal Investigator & Institution: Lee, Richard Edward.; Assistant Professor; Pharmaceutical Sciences; University of Tennessee Health Sci Ctr Memphis, Tn 38163 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2005 Summary: (provided by applicant): This proposal aims to use live, whole-cell, high resolution magic angle spinning nuclear magnetic resonance spectroscopy (HRMASNMR) as a novel, nondestructive technique to study carbohydrate and carbonaceous

metabolism in mycobacteria. There is currently intense research in genomic and proteomic studies of mycobacteria. However, complementary methodologies to study globally, the carbonaceous metabolic products from genes or proteins has been lacking and it is this deficit in knowledge that this proposal aims to address. Firstly, it is proposed to assign the complex, live, whole-cell HRMAS-NMR spectra of M. bovis BCG using purified standard metabolites and multi-dimensional NMR techniques. Secondly, it is proposed that mycobacteria can adapt their carbonaceous metabolism in response to different physiological conditions. Thus HRMAS-NMR, will be used to study changes in mycobacterial carbonaceous metabolites, including the cell wall, under different physiological conditions: (i) physical conditions of growth such as different media, temperature and pH; (ii) growth phase; (iii) exposure to anti-mycobacterial agents, including those which target the mycobacterial cell wall; (iv) the effects of conditions which may mimic growth in vivo; (v) differences in the HRMAS-NMR spectra between different mycobacterial species. The central hypothesis is that whole cell HRMAS-NMR will be an excellent way to study these changes. Thirdly, using whole cell NMR, a novel study will be performed of the mycobacterial cell wall tertiary structure. Initially, it is hoped to locate the position of metabolites identified in this study in the cell ultra structure. Finally, we plan to initiate 3D-NMR studies and studies of 3-bond torsional coupling constants that will provide 3-dimensional, conformational information on the macromolecules identified. The findings from these studies will lead to a better understanding of mycobacterial carbohydrate and lipid physiology and hence, their role in the virulence and pathogenesis of the tubercle bacilli.

With PubMed Central, NCBI is taking the lead in preservation and maintenance of open access to electronic literature, just as NLM has done for decades with printed biomedical literature. PubMed Central aims to become a world-class library of the digital age. 5 The value of PubMed Central, in addition to its role as an archive, lies in the availability of data from diverse sources stored in a common format in a single repository. Many journals already have online publishing operations, and there is a growing tendency to publish material online only, to the exclusion of print.

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.6 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with metabolites, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “metabolites” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for metabolites (hyperlinks lead to article summaries): •

PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

CHAPTER 2. NUTRITION AND METABOLITES Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and metabolites.
Finding Nutrition Studies on Metabolites The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “metabolites” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 5. PATENTS ON METABOLITES Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.8 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “metabolites” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on metabolites, we have not necessarily excluded nonmedical patents in this bibliography.
Patents on Metabolites By performing a patent search focusing on metabolites, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter. The following is an 8Adapted

Antibodies to specific regions of cyclosporine related compounds Inventor(s): Malcolm; Andrew J. (Alberta, CA), Naicker; S. Selvaraj (Alberta, CA), Yatscoff; Randall W. (Alberta, CA) Assignee(s): Isotechnika, Inc. (Edmonton, CA) Patent Number: 6,686,454 Date filed: September 3, 1999 Abstract: This invention relates to the production of polyclonal and monoclonal antibodies to specific regions of cyclosporine (CSA) and/or CSA metabolites/derivatives. The reactivity of these polyclonal and monoclonal antibodies make them particularly useful for immunoassays for therapeutic drug monitoring (TDM). These immunoassays or TDM kits may include polyclonal or monoclonal antibodies to specific sites of CSA and/or CSA metabolites. These kits may also include various combinations of polyclonal antibodies, polyclonal and monoclonal antibodies or a panel of monoclonal antibodies. Cyclosporine or CSA metabolite conjugate immunogens are prepared for the immunization of a host animal to produce antibodies directed against specific regions of the CSA or CSA metabolite molecule. By determining the specific binding region of a particular antibody, immunoassays which are capable of distinguishing between the parent molecule, active metabolites, inactive metabolites and other structurally similar immunosuppressant compounds are developed. The use of divinyl sulfone (DVS) as the linker arm molecule for forming cyclosporine and cyclosporine metabolite protein conjugate immunogens is described. Excerpt(s): This invention relates to the production of polyclonal and monoclonal antibodies to specific sites of cyclosporine and/or cyclosporine metabolites, derivatives and analogues. The reactivity of these polyclonal and monoclonal antibodies makes them particularly useful for immunoassays for therapeutic drug monitoring (TDM). These immunoassays or TDM kits may include polyclonal or monoclonal antibodies to specific sites of cyclosporine (CSA) and/or metabolites, derivatives and analogues of cyclosporine. These kits may also include various combinations of polyclonal antibodies, polyclonal and monoclonal antibodies or a panel of monoclonal antibodies. Currently, the two immunosuppressive drugs administered most often to prevent organ rejection in transplant patients are cyclosporine (CSA) and tacrolimus (FK-506 or FK). Rapamycin (Rapa) is another known immunnosuppressant. Cyclosporine's primary target appears to be the helper T lymphocytes. Cyclosporine acts early in the process of T cell activation, it has secondary effects on other cell types that are normally activated by factors produced by the T cells. Cyclosporine inhibits the production of interleukin 2 (IL2) by helper T cells, thereby blocking T cell activation and proliferation (amplification of immune response). It is effective both in the prevention and in the treatment of ongoing acute rejection. The current model for the mechanism of action of CSA suggests that, in the T cell cytoplasm, CSA binds to a specific binding protein called immunophilin. The CSA-immunophilin complex in turn binds to and blocks a phosphatase called calcineurin. The latter is required for the translocation of an activation factor (NF-ATc) from the cytosol to the nucleus, where it would normally bind to and activate enhancers/promoters of certain genes. In the presence of CSA, the cytosolic activation factor is unable to reach the nucleus, and the transcription of IL-2 (and other early activation factors) is strongly inhibited. As a result of this inhibition, T cells do not
Patents 169
proliferate, secretion of gamma-interferon is inhibited, no MHC class II antigens are induced, and no further activation of the macrophages occurs. Various side effects are associated with cyclosporine therapy, including nephrotoxicity, hypertension, hyperkalemia, hypomagnesemia and hyperuricemia. Neuro- or nephrotoxicity has been correlated with certain cyclosporine metabolites. A necessary requirement of cyclosporine drug monitoring assays is to measure the levels of parent cyclosporine drug and metabolite with immunosuppressive and toxic activity. There is a need for improved methods of monitoring levels of CSA and/or CSA metabolites and derivatives. Web site: http://www.delphion.com/details?pn=US06686454__ •
Apparatus for measurement and control of the content of glucose, lactate or other metabolites in biological fluids Inventor(s): Poscia; Alessandro (Orvieto, IT), Varalli; Maurizio Claudio (Milan, IT) Assignee(s): Menarini Industrie Farmaceutiche Riunite S.r.L. (Firenze, IL) Patent Number: 6,618,603 Date filed: May 7, 2001 Abstract: An apparatus for the continuous measurement of glucose and lactate in interstitial fluids including a glucose measurement cell, an A/D conversion block, a memory block and a bi-directional communication between the interface block and an external calculation unit. Excerpt(s): This invention relates generally to the field of measurement transducers, and more specifically, to electronic circuits for glucose content measurement instruments for personal independent use. Still more particularly, the invention relates to an apparatus for improved safety, flexibility of use, and improved measurement performance, in the near-continual determination of glucose or other molecules in extracellular fluids. The medical literature indicates the need to have dedicated instruments permitting almost continual measurement of the concentration in a patient's blood of certain specific molecules, such as glucose, lactate and others. Many such instruments dedicated to these measurements have been developed. One of the most serious drawbacks of prior devices has been the excessive invasiveness of known methods of measurement, which involve the need for direct access to a patient's blood vessels.

Bioactive tetracyclic diterpene compounds and methods of preparation and use thereof Inventor(s): Roncal; Tomas (San Sebastian, ES), Sterner; Olov (Malmoe, SE), Ugalde; Unai (Hondarribia, ES) Assignee(s): Universidad del Pais Vasco/Euskal Herriko Unibersitatea (Leioa, ES) Patent Number: 6,682,914 Date filed: October 31, 2001 Abstract: Newly-isolated and purified metabolites which are effective in regulating the development of at least one filamentous fungal microorganism species are disclosed. These compounds, which are referred to as conidiogenol and conidiogenone, may be

Metabolites
used to induce conidiation in and/or to inhibit the growth of populations of such fungal species. The compounds are preferably produced by culture of the fungal species Penicillium cyclopium, and may be subsequently recovered from the culture medium and purified. Methods of using and methods of producing these compounds are also disclosed. Excerpt(s): The present invention relates broadly to the isolation, identification and use of natural products. More particularly, this invention relates to substantially pure forms of two related biologically active diterpenoid compounds that are useful to regulate the development of microorganisms. Specifically, these substances may be used to induce conidiation in, and thereby also to inhibit the growth of, such microorganisms. The continuous deposition of new cell wall and plasma membrane material at a fixed cellular site (termed "apical extension") is a successful growth pattern which is widely observed in prokaryotic and eukaryotic organisms (Heath, 1990). The derived tubular structure (the hypha) offers great practical advantages for the colonization of solid substrates, as well as the undertaking of fungal infection. It acts as a device providing sheer physical force combined with a versatile arsenal of apically secreted enzymes directed at the hydrolysis of biopolymers and other bioconversions. However, apical extension growth is unsuitable for dispersive purposes or resistance to unfavorable environmental conditions, and filamentous microorganisms have evolved alternative morphogenetic programs to generate cell forms which cater to these requirements: spores (Smith and Berry 1974). The formation of conidia or asexual spores among filamentous fungi is a complex process in which a succession of precisely regulated cellular events take place in tight coordination. Environmental or endogenous stimuli are thought to trigger a set of genetically determined programs which lead to the cessation of apical growth, and to the development of reproductive asexual structures which finally result in the formation of conidia.

Bioreactive allosteric polynucleotides Inventor(s): Breaker; Ronald R. (Guilford, CT) Assignee(s): Yale University (New Haven, CT) Patent Number: 6,630,306 Date filed: May 4, 2001 Abstract: Polynucleotides having allosteric properties that modify a function or configuration of the polynucleotide with a chemical effector and/or physical signal are employed primarily as biosensors and/or enzymes for diagostic and catalytic purposes. In some preferred embodiments, the polynucleotides are DNA enzymes that are used in solution/suspension or attached to a solid support as biosensors to detect the presence or absence of a compound, its concentration, or physical change in a sample by observation of self-catalysis. Chemical effectors include organic compounds such as amino acids, amino acid derivatives, peptides, nucleosides, nucleotides, steroids, and mixtures of these with each other and with metal ions, cellular metabolites or blood components obtained from biological samples, steroids, pharmaceuticals, pesticides, herbicides, food toxins, and the like. Physical signals include radiation, temperature changes, and combinations thereof. Excerpt(s): This invention relates primarily to functional DNA polynucleotides that exhibit allosteric properties, and to catalytic RNA and DNA polynucleotides that have
Patents 171
catalytic properties with rates that can be controlled by a chemical effector, a physical signal, or combinations thereof. Bioreactive allosteric polynucleotides of the invention are useful in a variety of applications, particularly as biosensors. Biosensors are widely used in medicine, veterinary medicine, industry, and environmental science, especially for diagnostic purposes. Biosensors are typically composed of a biological compound (sensor material) that is coupled to a transducer, in order to produce a quantitative readout of the agent or conditions under analysis. Usually, the biological component of the biosensor is a macromolecule, often subject to a conformational change upon recognition and binding of its corresponding ligand. In nature, this effect may immediately initiate a signal process (e.g., ion channel function in nerve cells). Included in the group of `affinity sensors` are lectins, antibodies, receptors, and oligonucleotides. In biosensors, ligand binding to the affinity sensor is detected by optoelectronic devices, potentiometric electrodes, field effect transistors (FETs), or the like. Alternatively, the specificity and catalytic power of proteins have been harnessed to create biosensors that operate via enzyme function. Likewise, proteins have been used as immobilized catalysts for various industrial applications. The catalytic activity of purified enzymes or even whole organelles, microorganisms or tissues can be monitored by potentiometric or amperometric electrodes, FETs, or thermistors. The majority of biosensors that are commercially available are based on enzymes, of which the oxidoreductases and lyases are of great interest. It is nearly exclusively the reactants of the reactions catalyzed by these enzymes for which transducers are available. These transducers include potentiometric electrodes, FETs, pH- and O.sub.2 -sensitive probes, and amperometric electrodes for H.sub.2 O.sub.2 and redox mediators. For example, the oxidoreductases, a group of enzymes that catalyze the transfer of redox equivalents, can be monitored by detectors that are sensitive to H.sub.2 O.sub.2 or O.sub.2 concentrations.

Engineering of metabolic control Inventor(s): Liao; James C. (Los Angeles, CA) Assignee(s): Food Industry Research and Development Institute (CN) Patent Number: 6,706,516 Date filed: July 27, 2000 Abstract: The invention features a method of producing heterologous molecules in cells under the regulatory control of a metabolite and metabolic flux. The method can enhance the synthesis of heterologous polypeptides and metabolites. Excerpt(s): The use of recombinant DNA technology has allowed the engineering of host cells to produce desired compounds, such as polypeptides and secondary metabolites. The large scale production of polypeptides in engineered cells allows for the production of proteins with pharmaceutical uses and enzymes with industrial uses. Secondary metabolites are products derived from nature that have long been known for their biological and medicinal importance. Because of the structural complexity inherent in such molecules, traditional chemical synthesis often requires extensive effort and the use of expensive precursors and cofactors to prepare the compound. In recent years, the expression of heterologous proteins in cells has facilitated the engineering of heterologous biosynthetic pathways in microorganisms to produce metabolites from inexpensive starting materials. In this manner, a variety of compounds have been produced, including polyketides,.beta.-lactam antibiotics, monoterpenes, steroids, and aromatics. The invention is based, in part, on the discovery that production of
172
Metabolites
heterologous polypeptides and metabolites can be enhanced by the regulated expression of the polypeptide (e.g., a biosynthetic enzyme) using a promoter which is regulated by the concentrations of a second metabolite, e.g. acetyl phosphate. The term "heterologous" refers to a polypeptide or metabolite which is introduced by artifice. A heterologous polypeptide or metabolite can be identical to endogenous entity that is naturally present. The term "metabolite" refers to a organic compound which is the product of one or more biochemical reactions A metabolite may itself be a precursor for other reactions. A secondary metabolite is a metabolite derived from another. Accordingly, in one aspect, the invention features a bacterial host cell containing a nucleic acid sequence comprising a promoter and a nucleic acid sequence encoding a heterologous polypeptide. Examples of bacterial host cells include Escherichia coli, Bacillus subtilis, Salmonella typhimurium, Agrobacterium tumefaciens, Thermus thermophilus, and Rhizobium leguminosarum cells. The nucleic acid sequence is operably linked to the promoter which is controlled by a response regulator protein. In other words, the nucleic acid sequence is linked to the promoter sequence in a manner which allows for expression of the nucleotide sequence in vitro and in vivo. "Promoter" refers to any DNA fragment which directs transcription of genetic material. The promoter is controlled by a response regulator protein, for example, ntrC, phoB, phoP, ompR, cheY, creB, or torR, of E. coli or its homologs from other bacterial species. Further, the response regulator protein can be another member of the cluster orthologous group (COG) COG0745 as defined by http//www.ncbi.nlm.nih.gov/COG/(Tatusov et al. Nucleic Acids Res. (2000); 28:33-36). In one implementation, the promoter is bound by E. coli ntrC. The term "ntrC" refers to both the E. coli ntrC protein (SWISSPROT: P06713, http://www.expasy.ch/) and its homologs in other bacteria as appropriate. As used herein, "bound" refers to a physical association with a equilibrium binding constant (K.sub.D) of less than 100 nM, preferably less than 1 nM. An example of the promoter is the E. coli glnAp.sub.2 promoter, e.g. a region between positions about 93 and about 323 in the published DNA sequence, GenBank accession no. M10421(Reitzer & Magasanik (1985) Proc Nat Acad Sci USA 82:1979-1983). This region includes untranslated sequences from the glnA gene. Further, a translational fusion can be constructed between coding sequences for glnA and coding sequences for the heterologous polypeptide. Web site: http://www.delphion.com/details?pn=US06706516__ •
Felbamate derived compounds Inventor(s): Macdonald; Timothy L. (Charlottesville, VA) Assignee(s): University of Virginia Patent Foundation (Charlottesville, VA) Patent Number: 6,599,935 Date filed: December 17, 2001 Abstract: The present invention relates to novel felbamate derivatives and their use to treat neurological diseases such as epilepsy and to treat tissue damage resulting form ischemic events. The felbamate derivatives are modified to prevent the formation of metabolites that are believed responsible for the toxicity associated with felbamate therapy. Excerpt(s): The present invention is directed to novel derivatives of 2-phenyl-1,3propanediol dicarbamate (felbamate), and the use of such derivatives as therapeutic agents. More particularly, compositions comprising the present felbamate derivatives can be administered for reducing the incidence and severity of epileptic seizures and for

preventing and treating hypoxic damage resulting from an ischemic event. Felbamate (2-phenyl-1,3-propanediol dicarbamate) is a known pharmaceutical compound having been described in U.S. Pat. Nos. 2,884,444 and 4,868,327, the disclosures of which are expressly incorporated herein. Felbamate is a modulator of NMDA (N-methyl-Daspartate) receptor function, and a glycine site antagonist but also has other reported mechanisms of actions. Felbamate has also been reported to interact at the AMPA/kainate receptor, facilitate the function of the GABA receptor, and modulate Na.sup.+ channel conductance. Felbamate has also been demonstrated to decrease delayed neuronal cell death after kainic acid induced status epilepticus in animals. Glycine or d-serine were able to functionally reverse the anticonvulsant and ischemic protective effect of felbamate. Web site: http://www.delphion.com/details?pn=US06599935__ •
Fluorescent hplc assay for 20-hete and other p-450 metabolites of arachidonic acid Inventor(s): Maier; Kristopher G. (Milwaukee, WI), Roman; Richard J. (Brookfield, WI) Assignee(s): MCW Research Foundation (Milwauke, WI) Patent Number: 6,764,855 Date filed: February 14, 2003 Abstract: The present invention provides a fluorescent HPLC assay for detecting the presence and/or measuring the level of 20-hydroxyeicosatetraenoic acid (20-HETE) and other P-450 metabolites of arachidonic acid in a sample. P-450 metabolites of arachidonic acid are first extracted from the sample and then labeled with 2-(2,3naphthalimino)ethyl trifluoromethanesulfonate. The labeling reaction is catalyzed by N,N-diisopropylethylamine. Next, the labeled P-450 metabolites are separated on a 4.5.times.250-mm, 5.mu.M particle size C18 reverse-phase HPLC column using a mobile phase of methanol:water:acetic acid (82:18:0.1, v/v/v) and an isocratic elution at a rate of about 1.3 ml per minute. Fluorescence intensities of the column eluent are monitored by a fluorescence detector. Quantitation of P-450 metabolites in a sample can be made by using an internal standard. Excerpt(s): Not applicable. A variety of diseases such as salt sensitive hypertension, toxemia of pregnancy, asthma, hepatorenal syndrome, diabetes and subarachnoid hemorrhage are associated with abnormalities in arachidonic acid ("AA") metabolism. Recent studies have indicated that AA is primarily metabolized in the brain, kidney, lung, and vasculature by cytochrome P-450 enzymes to epoxyeicosatrienoic acids (EETs), dihydroxyeicosatrienoic acids (diHETEs), and 19and 20hydroxyeicosatetraenoic acids (19- and 20-HETE). McGiff J C and Quilley J, Am J Physiol Regulatory Integrative Comp Physiol 277: R607-R623 (1999); Roman R J and Alonso-Galicia M, News Physiol Sci 14: 238-242 (1999). 20-HETE and EETs are biologically active and have been implicated as paracrine factors and/or second messengers in the regulation of vascular tone, sodium and water excretion in the kidney, and airway resistance. McGiff J C and Quilley J, Am J Physiol Regulatory Integrative Comp Physiol 277: R607-R623 (1999); Roman R J and Alonso-Galicia M, News Physiol Sci 14: 238-242 (1999). Despite the importance of P-450 metabolites of AA, very little is known about the regulation of the concentrations of these mediators in tissue and biological fluids. Part of the problem has been the lack of a sensitive, inexpensive, and high-throughput assay to measure the endogenous concentration of these compounds. To date, gas chromatography-mass spectroscopy (GC-MS) with selective ion monitoring and one report of a fluorescent enzyme based immunoassay
174
Metabolites
("EIA") for EETs have been the only methods available to measure the concentration of P-450 metabolites of AA in biological samples. Capdevila J H et al. J Biol Chem 267: 21720-21726(1992); Catella F et al., Proc Natl Acad Sci USA 87: 5893-5897 (1990); Prakash C et al., Biochem Biophys Res Commun 185: 728-733 (1992); Schwartzman M L et al., Biochem Biophys Res Commun 180: 445-449 (1991); Toto R et al., Biochem Biophys Acta 191: 132-134 (1987). The EIA requires a specific antibody that is no longer generally available and, therefore, the assay cannot be reproduced in other labs. GC-MS has been successfully used to measure 20-HETE and EETs in the urine of humans and rats, and the reported concentration of these mediators is in the range of 0.5-5 ng/ml. The urinary excretion of EETs has been reported to increase in rats fed a high-salt diet and in patients with toxemia of pregnancy. Capdevila J H et al., J Biol Chem 267: 21720-21726 (1992); Oyekan A O et al., J Clin Invest 104:1131-1137(1999); Catella F et al., Proc Natl Acad Sci USA 87: 5893-5897 (1990). Moreover, the urinary excretion of 20-HETE is elevated in patients with hepatorenal syndrome and in DOCA-salt hypertensive rats. Sacerdoti D et al., J Clin Invest 100: 1264-1270 (1997); Oyekan A O et al., Am J Physiol Regulatory Integrative Comp Physiol 176: R766-R775 (1999). Although GC-MS is a reliable method for the measurement of P-450 metabolites of AA, the high cost for the purchase and maintenance of the instrumentation and difficulties in preparing the samples for analysis have limited the use of this technique. Indeed, the preparation of urine samples for GC-MS involves an organic extraction of the lipid fraction, separation of the EETs or HETEs fractions by thin-layer chromatography and reverse-phase HPLC, derivatization of the samples to the methyl or pentabenzylfluoro esters, and conversion of these esters to trimethylsilyl derivatives. Toto R et al., Biochem Biophys Acta 191: 132134 (1987). It also requires the synthesis and addition of a deuterated internal standard to the samples to correct for variable extraction and derivatization efficiencies. The extensive sample preparation reduces sample recoveries and the detection limits of this technique to the nanogram range. Oyekan A O et al., J Clin Invest 104: 1131-1137 (1999); Schwartzman M L et al., Biochem Biophys Res Commun 180: 445-449 (1991); Toto R et al. Biochem Biophys Acta 191: 132-134 (1987). GC-MS is also limited to the measurement of a single compound at a time. Web site: http://www.delphion.com/details?pn=US06764855__ •

The formulation disclosed herein comprises a resistance inducer, such as an isomer of amino butyric acid or another amino acid, which is capable of increasing the synthesis of essential oil in an aromatic plant. The formulation may further comprise secondary metabolites as well as a carrier. Aromatic plants that may be used in the present invention include, but are not limited to, rose-scented geranium (Pelargonium graveolens) and menthol mint (Mentha arvensis). The present invention also provides a method of increasing the essential oil content in aromatic crops and other plants.
Patents 175
Excerpt(s): The present invention relates to a formulation and a method useful for increasing the essential oil content of aromatic crops. In particular, this invention relates to a formulation comprising an amino acid, such as an isomer of amino butyric acid, wherein the formulation is capable of increasing or enhancing the essential oil content in aromatic plants. The concept of inducing resistance in plants in laboratories, glasshouse studies, and in the field has been demonstrated using abiotic and biotic elicitors, which may include complex carbohydrates, various amino and fatty acids, derivatives of salicylic, nicotinic and jasmonic acids, ethylene, glycoproteins, and the like. (Lyon et al., Plant Pathology, 44:407-27 (1995)). Such elicitors have also been shown to induce other biochemical changes, which affect plants and plant cell systems, such as photosynthesis (Pancheva et al., Journal of Plant Physiology 149:57-63 (1996)), anthocyanin accumulation (Berglund et al., Journal of Plant Physiology, 141:596-600 (1993)) and flowering (Krajncic and Nemec, Journal of Plant Physiology, 146:754-756 (1995)). These findings indicate that elicitors act as signal molecules for gene expression in plants. However, compounds or chemicals (such as elicitors) capable of enhancing the yields of secondary metabolites (such as essential oil) in aromatic plants, in vivo, are not presently known in the art.

(UCSD Veterans Administration Medical Center, Department of, San Diego, CA 92161) Assignee(s): none reported Patent Number: 6,627,153 Date filed: August 31, 2001 Abstract: A test device that assesses the concentration of an organ marker, a drug marker and a metabolite associated with the drug/organ interaction. Excerpt(s): This invention relates to an integrated assay system, more specifically, to assessing the effectiveness of a drug and the organ function of a patient by measuring the concentrations of an organ marker, a drug and/or one or more metabolites with an integrated test system. Many drugs are currently available to treat diseases such as diabetes mellitus, cancer, hypertension, seizure disorders and infection. However, a number of these drugs can be dangerous and have been shown to result in organ damage in certain patients. On occasion, permanent organ damage can go undetected because potential drug side effects are not monitored effectively. Such organ damage may eventually require an organ transplant or even lead to death. For example, the drug troglitazone helps diabetes patients to control abnormally high blood glucose levels. Most patients tolerate this drug well and develop no lasting harmful side effects. Others tolerate the drug initially, but suddenly develop liver disease. Fortunately, for most of these patients, organ damage can abate or disappear when the drug is discontinued. However, some patients can develop permanent liver damage, which may result in death or require a transplant, especially if the patient's liver function is not being monitored regularly. Accordingly, liver function tests are strongly recommended before and periodically during treatment with troglitazone. Web site: http://www.delphion.com/details?pn=US06627153__

Method for chemoprevention of prostate cancer Inventor(s): Raghow; Sharan (Collierville, TN), Steiner; Mitchell S. (Germantown, TN) Assignee(s): The University of Tennessee Research Corporation (Knoxville, TN) Patent Number: 6,632,447 Date filed: November 8, 2000 Abstract: This invention relates to the chemoprevention of prostate cancer and, more particularly, to a method of suppressing or inhibiting latent prostate cancer comprising administering to a mammalian subject a chemopreventive agent and analogs and metabolites thereof. The chemopreventive agent prevents, prevents recurrence of, suppresses or inhibit prostate carcinogenesis; and treats prostate cancer. Excerpt(s): Prostate cancer is one of the most frequently occurring cancers among men in the United States, with hundreds of thousands of new cases diagnosed each year. Unfortunately, over sixty percent of newly diagnosed cases of prostate cancer are found to be pathologically advanced, with no cure and a dismal prognosis. One approach to this problem is to find prostate cancer earlier through screening programs and thereby reduce the number of advanced prostate cancer patients. Another strategy, however, is to develop drugs to prevent prostate cancer. One third of all men over 50 years of age
Patents 177
have a latent form of prostate cancer that may be activated into the life-threatening clinical prostate cancer form. The frequency of latent prostate tumors has been shown to increase substantially with each decade of life from the 50s (5.3-14%) to the 90s (40-80%). The number of people with latent prostate cancer is the same across all cultures, ethnic groups, and races, yet the frequency of clinically aggressive cancer is markedly different. This suggests that environmental factors may play a role in activating latent prostate cancer. Thus, the development of chemoprevention strategies against prostate cancer may have the greatest overall impact both medically and economically against prostate cancer.

Method for cultivation of filamentous fungi Inventor(s): Huang; Ting-Kuo (Chang-He, TW), Wang; Pei-Ming (Kaohsiung, TW), Wu; Wen-Teng (Hsinchu, TW), Yuan; Gwo-Fang (Hsinchu, TW) Assignee(s): Food Industry Research & Development Institute (Hsinchu, TW) Patent Number: 6,746,862 Date filed: July 7, 2000 Abstract: The invention discloses a method for cultivation of filamentous fungi using a suspended nutritionally solid substrate, the method including the steps of: (a) preparing a medium comprising a nutritionally solid substrate; and (b) inoculating an inoculum into the medium comprising the nutritionally solid substrate in a bioreactor to carry out fermentation. The present invention combines the properties of solid-state culture and submerged culture. In addition, the present invention may employ an air-lift bioreactor with a net draft tube and the fed-batch process to elevate the yields of filamentous fungi and metabolites thereof. Excerpt(s): The present invention relates to a method for cultivation of filamentous fungi, and more particularly to a method for cultivation of filamentous fungi by using suspended nutritionally solid substrates. Generally, the method for fermentation of filamentous fungi can include the use of solid-state culture or submerged culture. The conventional method for the most part uses solid-state culture. One example of producing metabolites from Monascus species is directly inoculating Monascus species into solid nutritional medium such as grain medium, for example rice or wheat. Then, fermentation is carried out. The mycelia of Monascus species penetrate into the surface of the solid nutritional medium and grow during the period of fermentation. The pigments produced are absorbed so that the color of the medium turns purple. In addition, the mycelia also penetrate inside the grain particles. This phenomenon facilitates the production of pigments. In 1991, Johns and Stuar employed Carrageenan particles consisting of synthetic medium to simulate grain in culture (Johns and Stuar, (1991) J. Industrial Microbiology, 8:23-28). However, due to reasons such as structure, nutrition components, etc, the synthetic medium is not suitable for Monascus species in the production based on solid-state culture. Generally, to adequately make use of medium and maintain optimal temperature and humidity, the operation procedures of conventional solid-state culture are complex and time-consuming. Moreover, some
178

problems such as the restriction of oxygen transfer, contamination, etc., also make the scale-up difficult. Furthermore, because of the disadvantages of solid-state culture described above, the quality and quantity of the products are usually unstable. To solve this problem, many studies have developed submerged culture to carry out the fermentation. In 1982, Lin and Lizuka employed saccharide and cereal meals as a carbon source to solve the problems of scale-up and operation control (Lin and Lizuka, (1982) Appl. Environ. Microbiology, 43:671-676). However, the yield of the pigments is significantly reduced using this method. In 1984, Evans and Wang employed algin (an inert substance in which no nutrient is contained) to immobilize Monascus species and then carry out submerged culture. The result showed the phenomenon of mycelia attachment conduces the production of the pigments (Evans and Wang, (1984) Applied and Environmental Microbiology 47(6): 1323-1326). In 1990, Mak et. al. introduced roller bottle culture, which has the properties of high oxygen mass transfer and low shear stress to provide an environment for mycelia attachment, and used glucose as a carbon source to carry out the cultivation of Monascus species (Mak et. al., (1990) Enzyme Microbiol. Technol., 12:965-968). However, due to the nature of the roller bottle, the scale of the production is too small using this method. In 1995, Lee et. al. used topioca starch as a carbon source and pointed out that a high initial starch concentration in the medium is not suitable for practical use due to high viscosity of the medium (Lee et. al., (1995) J. Fermentation of Bioengineering, 79(5): 516-518). They proposed a solid-liquid state culture with gelatinized starch block provided at the bottom and a dilute soluble starch at the upper part of the reactor. The cultivation was carried out in a stirred-tank bioreactor. However, their proposed approach might have scale-up problem since the interface area to volume ratio is small for a large-scale system.

Method for detecting the presence of microbes and determining their physiological status Inventor(s): Lloyd; Christopher R. (North Logan, UT), Powers; Linda S. (Logan, UT) Assignee(s): Microbiosystems, Limited Partnership (Cheyenne, WY) Patent Number: 6,750,006 Date filed: January 22, 2002 Abstract: Method and apparatus for the detection of microbes in liquids, in air and on non-living surfaces in which samples are exposed to electromagnetic radiation of specific energies capable of exciting various metabolites, cofactors and cellular and spore components, with the microbial cells to be sampled (and more specifically the excited metabolites, cofactors and or other cellular components) contained therein emit fluorescence that can be measured. The signal from the background and scattered excitation signals is removed from the fluorescence signals of the microbial components, the relative fluorescent signals of the intrinsic microbial components are required to lie within physiological ranges, and the amplitude of the background-corrected fluorescence signals used to enumerate the microbe content in the sample. Excerpt(s): This invention relates to a method and apparatus for sensing the presence of microbes (bacteria, fungi, protozoa, rickettsiae and or other microorganisms) and spores on non-living surfaces, in air and in liquids. It is of course elementary that all microbial cells produce energy for their cellular activity through respiration. As cellular respiration occurs in living cells, pyridine nucleotides are reduced, flavins are oxidized, and other coenzymes and metabolites are produced. Alternatively, spores are found to
Patents 179
be abundant with a calcium dipicolinic acid complex (a fluorescent compound otherwise rare in nature). The oxidation state of pyridine nucleotides, flavins and other cofactors, and/or the presence of calcium dipicolinate, can be simultaneously elucidated by concurrent excitation of each component with the appropriate electromagnetic radiation followed by detection of the characteristic radiation emitted by these individual fluorophores. Simultaneous excitation of a sample with multiple energies characteristic of the excitation for fluorescent cellular and endospore components with the subsequent collection and detection of emitted and reflected/scattered light energies (both associated with and independent of the fluorophores, respectively) is fundamental for the detection of microbes in a sample or on a non-living surface by the method described herein. The detection of respiring cells in real world samples is made more reliable by the aforementioned method for two reasons. First, the simultaneous excitation of microbes by multiple excitation energies and ensuing coincident detection of numerous fluorescence signals reduces the chance of interference, as the probability of an interference source duplicating the characteristics of numerous fluorophores is extremely small. Second, the relative quantities of the intrinsic metabolites, and thus of the resulting fluorescent signals, have been found to fall within defined physiological ranges. Analysis of the signals is achieved with a method capable of two things: (1) separating the detected fluorescent signals originating from any microbes present from interferences or background signals and or scattered excitation signals, and (2) a requirement that the intensities of the signals from microbial metabolites, microbial components and spore components fall within physiological ranges. Thus, the basis for the detection of microbes in a sample is comprised of the following steps: first, excitation of a sample simultaneously with multiple excitation energies characteristic of cellular metabolites, microbial components, and spore components; second, the subsequent collection of the numerous individual fluorescence signals (associated with the maxima and minima of the emissions of these excited metabolites); and finally, analysis of the collected signals with a method capable of removing background fluorescence and comparing the relative signal magnitudes of metabolites to known physiological ranges.

Molecular constructs with a carcinoembryonic antigen (CEA) transcriptional regulatory sequence Inventor(s): Huber; Brian (Durham, NC), Richards; Cynthia A. (Durham, NC) Assignee(s): SmithKline Beecham Corporation (Philadelphia, PA) Patent Number: 6,699,690 Date filed: September 6, 2001 Abstract: Novel molecular chimaeras produced by recombinant DNA techniques are described. They comprise a target-tissue specific transcriptional regulatory sequence (TRS) linked and controlling the expression of a heterologous enzyme, for example Varicella Zoster Virus Thymidine Kinase (VZV TK) or non-mammaliam Cytosine Deaminase (CD). A molecular chimaera is packaged into a synthetic retroviral particle that is capable of infecting mammalian tissue. This, in turn, may be administered to a host, and the TRS will be selectively transcriptionally activated in the target tissue (for example cancerous cells). Administration of compounds that are selectively metabolised by the enzyme produce cytotoxic or cytostatic metabolites in situ thereby selectively killing or arresting the growth of the target cells. Excerpt(s): The present invention relates to molecular chimaeras in infective virions: methods of their construction; pharmaceutical formulations containing them; their use in therapy, particularly virus-directed enzyme prodrug therapy, particularly in the treatment of cancers, and more particularly in the treatment of hepatocellular and colorectal carcinomas; and the use of agents which can be catalysed by a heterologous enzyme to cytotoxic or cytostatic metabolites, such as purine arabinosides and substituted pyrimidines and cytosines in virus-directed enzyme prodrug therapy in a host (e.g., mammal or human). Cancer of all forms is one of the major causes of morbidity throughout the world. Research in cancer chemotherapy has produced a variety of antitumour agents with differing degrees of efficacy. Standard clinically used agents include adriamycin, actinomycin D, methotrexate, 5-fluorouracil, cisplatin, vincristine and vinblastine. However, these presently available antitumour agents are known to have various disadvantages such as toxicity to healthy cells and resistance of certain tumour types. Other forms of therapy, such as surgery, are known. However it is appreciated by those skilled in the art that novel approaches and entities for cancer therapy are still needed. Hepatocellular carcinoma (HCC) is one of the major malignant diseases in the world today; the greatest incidence being in Japan, China, other parts of Asia, and sub-Saharan Africa. Recent evidence suggests that the incidence of hepatocellular carcinoma in Europe and North America is increasing. The disease is estimated to be responsible for or involved in up to approximately 1,250,000 deaths a year, making it one of the world's major malignant diseases.

Multi-channel non-invasive tissue oximeter Inventor(s): Barrett; Bruce J. (Birmingham, MI), Gonopolsky; Oleg (West Bloomfield, MI), Scheuing; Richard S. (Rochester Hills, MI) Assignee(s): Somanetics Corporation (Troy, MI) Patent Number: 6,615,065 Date filed: July 12, 2001 Abstract: A method and apparatus for spectrophotometric in vivo monitoring of blood metabolites such as hemoglobin oxygen concentration at a plurality of different areas or regions on the same organ or test site on an ongoing basis, by applying a plurality of spectrophotometric sensors to a test subject at each of a corresponding plurality of testing sites and coupling each such sensor to a control and processing station, operating each of said sensors to spectrophotometrically irradiate a particular region within the test subject; detecting and receiving the light energy resulting from said spectrophotometric irradiation for each such region and conveying corresponding signals to said control and processing station, analyzing said conveyed signals to determine preselected blood metabolite data, and visually displaying the data so determined for each of a plurality of said areas or regions in a comparative manner. Excerpt(s): This invention relates generally to in vivo spectrophotometric examination and monitoring of selected blood metabolites or constituents in human and/or other living subjects, e.g., medical patients, and more particularly to spectrophotometric oximetry, by transmitting selected wavelengths (spectra) of light into a given area of the test subject, receiving the resulting light as it leaves the subject at predetermined locations, and analyzing the received light to determine the desired constituent data based on the spectral absorption which has occurred, from which metabolic information such as blood oxygen saturation may be computed for the particular volume of tissue through which the light spectra have passed. A considerable amount of scientific data and writings, as well as prior patents, now exist which is/are based on research and clinical studies done in the above-noted area of investigation, validating the underlying technology and describing or commenting on various attributes and proposed or actual applications of such technology. One such application and field of use is the widespread clinical usage of pulse oximeters as of the present point in time, which typically utilize sensors applied to body extremities such as fingers, toes, earlobes, etc., where arterial vasculature is in close proximity, from which arterial hemoglobin oxygenation may be determined non-invasively. A further and important extension of such technology is disclosed and discussed in U.S. Pat. No. 5,902,235, which is related to and commonly owned with the present application and directed to a non-invasive spectrophotometric cerebral oximeter, by which blood oxygen saturation in the brain may be non-invasively determined through the use of an optical sensor having light emitters and detectors that is applied to the forehead of the patient. Earlier patents commonly owned with the '235 patent and the present one pertaining to various attributes of and applications for the underlying technology include U.S. Pat. Nos. 5,139,025; 5,217,013; 5,465,714; 5,482,034; and 5,584,296. The cerebral oximeter of the aforementioned '235 patent has proved to be an effective and highly desirable clinical instrument, since it provides uniquely important medical information with respect to brain condition (hemoglobin oxygen saturation within the brain, which is directly indicative of the single most basic and important life parameter, i.e. brain vitality). This information was not previously available, despite its great importance, since there really is no detectable arterial pulse within brain tissue itself with respect to which pulse oximetry could be utilized even if it could be effectively utilized in such an interior location (which is very doubtful), and
184
Metabolites
this determination therefore requires a substantially different kind of apparatus and determination analysis. In addition, there are a number of uniquely complicating factors, including the fact that there is both arterial and venous vasculature present in the skin and underlying tissue through which the examining light spectra must pass during both entry to and exit from the brain, and this would distort and/or obscure the brain examination data if excluded in some way. Furthermore, the overall blood supply within the skull and the brain itself consists of a composite of arterial, venous, and capillary blood, as well as some pooled blood, and each of these are differently oxygenated. In addition, the absorption and scatter effects on the examination light spectra are much greater in the brain and its environment than in ordinary tissue, and this tends to result in extremely low-level electrical signal outputs from the detectors for analysis, producing difficult signal-to-noise problems.

Metabolites
Excerpt(s): The present invention is in the field of biopesticides. More particularly, this invention relates to a novel strain of Streptomyces with insecticidal activity and methods of use thereof. Natural products are substances produced by microbes, plants, and other organisms. Microbial natural products offer an abundant source of chemical diversity. There is a long history of utilizing these natural products for pharmaceutical purposes. Despite the emphasis on natural products for human therapeutics, there are only a few natural product insecticides for agricultural use. The most successful microbial natural product insecticides are the Bacillus thuringiensis toxins, avermectin and the spinosyns. Bacillus thuringiensis (Bt) bacteria produce cytoplasmic protein crystals (.delta.-endotoxins) during sporulation which are the most important factor in insect pathogenesis (see, Ellar, D. J. (1997) "The structure and function of Bacillus thuringiensis.delta.-endotoxins and prospects for biopesticide improvement," In: Microbial Insecticides: Novelty or Necessity? The British Crop Protection Council Symposium Proceedings No. 68, Coventry, UK). The.delta.-endotoxins have been used in both spray preparations as well as `systemic` biopesticides through the introduction of the endotoxin genes into transgenic plants. The growth of the market for the spray preparations of Bt is estimated to be around 10% for 1997 through 2000, which will result in a market of $100-$130 million by 2000 (see, Lisansky, S. (1997) "Microbial biopesticides" In: Microbial Insecticides: Novelty or Necessity? The British Crop Protection Council Symposium Proceedings No. 68, Coventry, UK.). The main Bt transgenic crops are maize and cotton. The transgenic Bt maize market in the U.S. has grown from only 1.4% of the planted acreage in 1996 to 19.1% in 1998. The growth in Bt cotton has not been as drastic, increasing from 14.6% of the planted acreage in 1996 to 16.8% in 1998. The entire market is currently directed against lepidopteran pests. In 1999, the market for pesticides used against caterpillars in the US exceeded 400 million dollars US. The avermectins are produced by Streptomyces avermitilis during fermentation. Abamectin, one of the naturally occurring macrocyclic lactones, shows activity against mites, pear psylla and diamond back moth. Emamectin, a semi-synthetic analog of abamectin, shows activity against lepidopteran larvae. In invertebrates the avermectins induce the opening of a pre-synaptic chloride ion channel (not GABAactivated), leading to efflux of chloride ions, depolarization of the nerve terminal, and hence, to neurotransmitter release. See, Turner, M. J. and Schaeffer, J. M. (1989) "Mode of action of Ivermectin," In: Ivermectin and Abamectin, W. C. Campbell (Ed.) SpringerVerlag, N.Y. The use of avermectins in insect control had an estimated world market value of $80-$120 million in 1998. Web site: http://www.delphion.com/details?pn=US06682925__ •

However, several investigations have proved effect just below the significance limit. Anyhow, the patients' wellbeing during treatment with N-Acetyl-L-cysteine is significant. N-Acetyl-L-cysteine is registered as a mucolytic agent for peroral administration under trade marks such as Fabrol.RTM., Inspir.RTM. and Mucomust.RTM. N-Acetyl-cysteine has a low bioavailability, only about 4-10%, when administered perorally, see Mack R. Holdiness, "Clinical Pharmacokinetics of NAcetylcysteine", Clin. Pharmacokinet., 1991;20(2):123-134. The following references confirm the low bioavailability of N-Acetyl-L-cysteine: L. Borgstrom et al., "Pharmacokinetics of N-Acetylcysteine in Man", Eur J Clin Pharmacol. 1986;31:217-222, L. Borgstrom et al., "Dose dependent pharmacokinetics of N-Acetylcysteine after oral dosing to man", Biopharmaceutics & Drug Disposition, 1990(II):131-136, B. Olsson et al., "Pharmacokinetics and Bioavailability of Reduced and Oxidized N-Acetylcysteine", Eur J Clin Pharamcol. 1988;34:77-82. Martindale, "The Extra Pharmacopoeia", London, 1993, recommends a peroral dosing of 200 mg three times daily to adults, 200 mg once daily for children up to 2 years and 200 mg twice daily for children aged 2 to 6 years. Deutsche Apotheker Zeitung; 34; 1990 indicates that the maximum plasma level is reached 2 to 3 hours after oral administration. The same reference indicates 4% bioavailability upon oral administration. Web site: http://www.delphion.com/details?pn=US06620428__ •
Use of lipoxygenase metabolite of arachidonic acid and its derivatives in capsaicinchannel agonist Inventor(s): Hwang; Sun Wook (Seoul, KR), Oh; Uhtaek (Eul-gi Apt., 615-102, Sanbon 2dong, Kunpo-si, 435-042, Kyunggi-do, KR) Assignee(s): Oh; Uhtaek (Kyunggi-do, KR) Patent Number: 6,673,840 Date filed: February 6, 2001 Abstract: Disclosed is the use of metabolites produced from arachiconic acid by the catalytic action of lipoxygenase as capsaicin-channel or- receptor agonists. The lipoxygenase metavolites of arachidonic acid and their derivatives can activate the capsaicin channel to excite pain nerves, causing serious pain. In contrast, the capsaicin channel activation of the pain nerves, so that an analgesic effects are brought about. The lipoxygenase metabolites of arachidonic acid can be used as an analgesic and in searching for and developing analgesics. Excerpt(s): This is a 371 of PCT/KR99/00421, filed Aug. 2, 1999.

action of lipoxygenase, which can be used as an analgesic which is superior in painrelieving efficacy and free of durg resistance and addition. Analgesics developed thus far are largely classified into two categories: narcotic and antiphlogistic. The former, exerting its pharmacological effects on the central nervous system, shows potent painalleviating activity with accompaniments of strong side effects including resistance and addiction. With an unclear explanation regarding their pharmaceutical mechanism, antiphlogistic analgesics are weaker in pain relief than narcotic analgesics as well as may cause gastric and liver troubles (Insel, 1996; Reisine and Pasternak, 1996).

Analogs of indole-3-carbinol metabolites as chemotherapeutic and chemopreventive agents Inventor(s): Chao, Wan-Ru; (Sunnyvale, CA), Jong, Ling; (Sunnyvale, CA) Correspondence: Reed & Eberle Llp; 800 Menlo Avenue, Suite 210; Menlo Park; CA; 94025; US Patent Application Number: 20040043965 Date filed: August 20, 2002 Abstract: Novel compounds useful as chemotherapeutic and chemopreventive agents are provided. The compounds are analogs of indole-3-carbinol metabolites wherein the structures and substituents of the compounds are selected to enhance the compounds' overall efficacy, particularly with respect to therapeutic activity, oral bioavailability, long-term safety, patient tolerability, and therapeutic window. The compounds are useful not only in treatment of cancer but also in prevention of cancer. One preferred class of the novel compounds have the structure of formula (I) 1wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9, R.sup.10, R.sup.11, and R.sup.12 are defined herein. Pharmaceutical compositions are provided as well, as are methods of synthesis and use. Excerpt(s): This invention relates generally to compounds and compositions for the treatment of cancer and other hyperproliferative diseases. More particularly, the invention pertains to novel dietary indole analogs that are useful in treating a range of cancers, including estrogen-related cancers such as breast, uterine, cervical, ovarian, and endometrial cancers, and non-estrogen-related cancers such as prostate, colon, liver and lung cancers. Cancer is the second leading cause of death in the United States, exceeded only by heart disease. Drugs that are used to treat cancer tend to be toxic at their therapeutic dose levels, commonly causing severe and even life-threatening adverse effects. Current anticancer drugs must also be administered intravenously. Consequently, nearly all cancer chemotherapy must be administered in a hospital or clinic. An additional problem with most current cancer chemotherapy is that cancers frequently develop resistance to the drugs, so that recurrence of disease is common. For patients who have been diagnosed with cancer, cytotoxic chemotherapy is considered an essential part of the management of the disease, but resistance to chemotherapeutic drugs is unfortunately a common development in cancer. Although the mechanisms of resistance to chemotherapy are not fully understood, the cellular mechanisms thus far implicated in the development of drug resistance are the same as those that protect normal tissues from toxicity. Furthermore, the efficacy of cytotoxic chemotherapeutics is ultimately limited by their narrow therapeutic index. Therefore, it is unlikely that any breakthrough in the treatment of cancer will come about as a result of a cytotoxic

approach. There is accordingly an urgent need for new noncytotoxic therapies that are safer and more effective than those currently available, and that, furthermore, will improve both survival rate and the quality of life for cancer survivors.

Analogs of thalidomide as potential angiogenesis inhibitors Inventor(s): Eger, Kurt; (Leipzig, DE), Figg, William D.; (Fairfax, VA), Guetschow, Michael; (Bonn, DE), Hauschildt, Sunna; (Leipzig, DE), Hecker, Thomas; (Erfurt, DE), Teubert, Uwe; (Hameln, DE), Weiss, Michael; (Bethesda, MD) Correspondence: Klarquist Sparkman, Llp; 121 S.W. Salmon Street, Suite #1600; One World Trade Center; Portland; OR; 97204-2988; US Patent Application Number: 20040077685 Date filed: November 14, 2003 Abstract: A number of thalidomide metabolites having superior anti-angiogenic properties have now been isolated and identified In addition, thalidomide analogs that mimic the effects of the isolated and identified active thalidomide metabolites, and variations of such thalidomide analogs, have been developed. Such thalidomide analog compounds show enhanced potency in the inhibition of undesirable angiogenesis without the undesirable effects of administration of thalidomide. Excerpt(s): The present invention concerns anti-angiogenesis compositions and methods, and particularly thalidomide analogs that actively inhibit angiogenesis in humans and animals. Angiogenesis is the formation of new blood vessels from preexisting vessels. Angiogenesis is prominent in solid tumor formation and metastasis. A tumor requires formation of a network of blood vessels to sustain the nutrient and oxygen supply for continued growth. Some tumors in which angiogenesis is important include most solid tumors and benign tumors, such as acoustic neuroma, neurofibroma, trachoma, and pyogenic granulomas. Prevention of angiogenesis could halt the growth of these tumors and the resultant damage due to the presence of the tumor. It has been shown that there is a direct correlation between tumor microvessel density and the incidence of metastasis. Tumor cells themselves can produce factors that stimulate the proliferation of endothelial cells and new capillary growth. Angiogenesis is important in two stages of tumor metastasis. The first stage where angiogenesis stimulation is important is in the vascularization of the tumor, which allows tumor cells to enter the blood stream and to circulate throughout the body. After the tumor cells have left the primary site, and have settled into the secondary, metastasis site, angiogenesis must occur before the new tumor can grow and expand. Therefore, prevention of angiogenesis could lead to the prevention of metastasis of tumors and possibly contain the neoplastic growth at the primary site. These observations have led to the investigation of anti-angiogenic agents as possible therapeutic options for various cancers. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Excerpt(s): The present invention relates to 2-amino-benzoxazole sulfonamides, their use as aspartic protease inhibitors, in particular as broadspectrum HIV protease inhibitors, processes for their preparation as well as pharmaceutical compositions and diagnostic kits comprising them. The present invention also concerns combinations of the present 2-aminobenzoxazole sulfonamides with another anti-retroviral agent. It further relates to their use in assays as reference compounds or as reagents. The virus causing the acquired immunodeficiency syndrome (AIDS) is known by different names, including T-lymphocyte virus III (HTLV-III) or lymphadenopathy-associated virus (LAV) or AIDS-related virus (ARV) or human immunodeficiency virus (HIV). Up until now, two distinct families have been identified, i.e. HIV-I and HIV-2. Hereinafter, HIV will be used to generically denote these viruses. One of the critical pathways in a retroviral life cycle is the processing of polyprotein precursors by aspartic protease. For instance with the HIV virus the gag-pol protein is processed by HIV protease. The correct processing of the precursor polyproteins by the aspartic protease is required for the assembly of infectious virions, thus making the aspartic protease an attractive target for antiviral therapy. In particular for HIV treatment, the HIV protease is an attractive target. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Compositions and methods for minimizing adverse drug experiences associated with oxybutynin therapy Inventor(s): Ebert, Charles D.; (Salt Lake City, UT), Sanders, Steven W.; (Salt Lake City, UT) Correspondence: Thorpe North & Western; P.O. Box 1219; Sandy; UT; 84091-1219; US Patent Application Number: 20040120996 Date filed: December 8, 2003 Abstract: The present invention provides compositions and methods for administering oxybutynin while minimizing the incidence and or severity of adverse drug experiences associated with oxybutynin therapy. In one aspect, these compositions and methods provide a lower plasma concentration of oxybutynin metabolites, such as Ndesethyloxybutynin, which is presumed to be contributing at least in part to some of the adverse drug experiences, while maintaining sufficient oxybutynin plasma concentration to benefit a subject with oxybutynin therapy. The invention also provides isomers of oxybutynin and its metabolites that meet these characteristics of minimized incidence and/or severity of adverse drug experiences, and maintenance of beneficial and effective therapy for overactive bladder. Excerpt(s): This patent application is a continuation of U.S. patent application Ser. No. 10/098,752, filed Mar. 15, 2002, which is a continuation of U.S. patent application Ser. No. 09/559,711, filed Apr. 26, 2000, each of which are incorporated herein by reference. The present invention relates to compositions and methods for minimizing adverse drug experiences associated with oxybutynin therapy. Accordingly, this invention covers the fields of pharmaceutical sciences, medicine and other health sciences. Oral oxybutynin is currently used for treating various forms of overactive bladder and urinary incontinence. Particularly, oxybutynin effectively treats neurogenically caused bladder disorders. Relief from such disorders is attributed to the anticholinergic and antispasmodic action which oxybutynin imparts to the parasympathetic nervous system and the urinary bladder detrusor muscle.

Compositions and methods for simultaneous detection of volatile sulfur compounds and polyamines Inventor(s): Pendergrass, James C.; (Lexington, KY) Correspondence: George David Mcclure JR.; P.O. Box 21902; Lexington; KY; 40622; US Patent Application Number: 20040076584 Date filed: October 18, 2002 Abstract: Disclosed are compositions and methods useful for the rapid and facile simultaneous detection of malodorous bacterial metabolites in samples of expired breath and other fluids. The invention enables estimation, by simple visual inspection and comparison against standards, of the concentration of polyamines and volatile sulfur compounds in the micromolar to millimolar range. Excerpt(s): The invention relates to, among other fields, the field of diagnostic tests to detect the presence of pathogenic microorganisms. In normal circumstances many microorganisms live on or in humans without causing harm to these humans. However, an increased number of certain microorganisms can be associated with a disease state.
Patents 193
Particularly problematic is an increase in the number of microorganisms that produce significant concentrations of chemicals that arc toxic to humans. Such toxins include: volatile sulfur compounds (VSCs), such as hydrogen sulfide, methyl mercaptan, dimethyl disulfide, and dimethyl sulfide; and polyamines, such as putrescine and cadaverine. Higher concentrations of volatile sulfur compounds and of polyamines are associated with certain disease states and with socially stigmatized conditions, such as halitosis, or bad breath. It would be desirable to enable facile simultaneous detection of volatile sulfur compounds and polyamines in order to facilitate detection of the presence of potentially pathogenic microorganisms and of disease states and conditions with which these microorganisms are associated. The principal VSCs produced by oral bacteria are hydrogen sulfide (H.sub.2S) and methylmercaptan (CH.sub.3SH). H.sub.2S is produced by the bacterial enzyme L-cysteine desulthydrase, which degrades the amino acid L-cysteine to produce H.sub.2S, ammonium and 2-ketopropanate. The other major VSC, CH.sub.3SH, is produced by the action of the bacterial enzyme L-methionine gamma lyase, which breaks down the amino acid L-methionine to produce CH.sub.3SH, ammonium and 2-ketobutyrate. H.sub.2S levels have been reported to occur at levels as high as 2 mM in the gingival crevice of persons with severe periodontal disease.

O. Box 1135; Chicago; IL; 60690-1135; US Patent Application Number: 20040115308 Date filed: February 2, 2004 Abstract: The present invention relates to any kinds of consumable products enriched with probiotics and a method for obtaining them. After production of probiotic biomass, the probiotics are applied to the product. Also metabolites obtained from a fermentation product may be directly applied to a consumable product. Excerpt(s): The present invention relates to a consumable product containing probiotics and to a process for obtaining it. Probiotic micro-organisms are micro-organisms which beneficially affect a host by improving its intestinal microbial balance. In general, it is believed that these bacteria inhibit or influence the growth and/or metabolism of pathogenic bacteria in the intestinal tract. It is also assumed that via probiotic microorganisms the immune function of the host is activated. For this reason, there have been many different approaches to include probiotic micro-organisms into food-stuffs. WO98/10666 (SOCIETE DES PRODUITS NESTLE S.A.) discloses a process for manufacturing a dehydrated food composition containing live probiotic acid bacteria, in which a food composition and a culture of probiotic lactic acid bacteria sensitive to oxygen are sprayed conjointly under a stream of hot air.

Dental implement and method for tooth surface inspection Inventor(s): de Josselin de Jong, Elbert; (Amsterdam, NL), van der Veen, Monique; (Amsterdam, NL), Waller, Elbert; (Amsterdam, NL) Correspondence: Woodard, Emhardt, Naughton, Moriarty And Mcnett; Bank One Center/tower; 111 Monument Circle, Suite 3700; Indianapolis; IN; 46204-5137; US Patent Application Number: 20040023184 Date filed: July 31, 2002 Abstract: Described are dental implements useful for inspecting tooth surfaces for abnormalities such as caries or plaque. Preferred implements of the invention include light emitting diodes mounted on an implement body having a mirror for insertion into a user's mouth. Such implements also have on-board batteries mounted in chambers in the implement handle, and a switch for energizing and de-energizing the LED with the battery. Also described are methods for examining tooth surfaces for abnormal conditions indicative of plaque involving illuminating surfaces with radiation at a wavelength in the range of 390-450 nm wherein the radiation is effective to cause detectable fluorescence emissions from bacterial metabolites known to be associated with plaque-containing surfaces, and detecting the emissions. Excerpt(s): The present invention relates generally to devices and methods for inspecting tooth surfaces, and in particular to such devices and methods involving the detection of differential fluorescence emissions from abnormal and healthy tooth surfaces. As further background, various devices and methods have been proposed that involve using fluorescence emissions to detect caries or other abnormal conditions. For example, U.S. Pat. No. 3,711,700 relates to a disclosing light for inspecting tooth surfaces. The disclosing light is designed for use in conjunction with a fluorescent dye such as sodium fluorescein. The disclosing light includes a light source and a dichroic reflector behind the light source to reflect blue light forward and the remainder backward. A second dichroic filter is positioned in front of the light source and transmits blue light and reflects back infrared radiation. A mirror reflects yellow light to the observer and transmits other wavelengths. U.S. Pat. No. 4,266,535 discloses a diagnostic lamp for use in conjunction with a fluorescent dye to inspect tooth surfaces. The lamp includes an incandescent bulb light source used in conjunction with a lens to supply a divergent beam of rays. A blue filter with an applied dichroic filter is used to filter the rays, which are made to impinge upon the fluorescent dye. The resulting fluorescence can be viewed in a folding, adjustable mirror. U.S. Pat. No. 5,957,687 discloses another diagnostic unit including a filtered light source and a mirror contained in a housing. Filtered light is concentrated in the blue frequency range and causes fluorescent dye to fluoresce. This can then be viewed in the mirror.

Abstract: The present invention relates to a method for producing a gene product by expressing a gene encoding said gene product in angiosperm host cells, which method comprises: a) constructing a vector expressible in angiosperm host cells, said vector comprising a promoter region derived from an amylase gene selected from SBAmyA, SBAmyB, SBAmyC genes or SBAmyD of the sugar beet and a gene encoding a desired gene product; b) transforming a compatible angiospasm host cell with said vector; c) cultivating the resulting transformant host cell to a sugar-depleted or sugar-free condition to promote the expression of said gene under the control of such promoter region; and d) recovering the product of the expressed gene. The sugar beet gene when incorporated into a dicot seed or plant has improved biological properties. The gene sequences and the products thereof are claimed. Excerpt(s): This invention relates to specific DNA sequences which are capable of expressing foreign proteins and their metabolites in dicotyledonous plants and cell culture. Specifically, the present invention concerns the incorporation into a vector and expressing of the SBAmyB or SBAmyC gene of the sugar beet and recovering the product of the expressed gene. The incorporation of the sugar beet genes SBAmyB or SBAmyC for.alpha.-amylase have not yet been reported. The synthesis of.alpha.amylase and levels of their mRNa are greatly induced under sucrose starvation. An increase of.alpha.-amylase synthesis is assumed to accelerate hydrolysis of cellular starch as an energy source when exogenous carbon source is depleted. Under normal growth condition with an adequate supply of sugars in the medium, the expression of.alpha.-amylase genes is subject to metabolite repression. It was observed that.alpha.amylases synthesized by the cultured rice cells are secreted into the culture medium and can account for about 15-20% of the total proteins present in the medium during periods of sugar depletion.

Mammalian metabolites of a tachykinin receptor antagonist Inventor(s): Chiu, Shuet-Hing Lee; (Westfield, NJ), Huskey, Su-er Wu; (Westfield, NJ) Correspondence: Merck And CO Inc; P O Box 2000; Rahway; NJ; 070650907 Patent Application Number: 20040023960 Date filed: April 24, 2003 Abstract: This invention is concerned with mammalian metabolites of the compound 2(R)-(1-(R)-(3,5-bis(trifluoromethyl)phenyl)ethoxy)-3-(S)-(4-fluoro)-phe- nyl-4-(3-(5-oxo1H,4H-1,2,4-triazolo)methylmorpholine which is a tachykinin receptor antagonist that is useful in the prevention and treatment of certain disorders, including emesis and psychiatric disorders such as depression and anxiety. Excerpt(s): Substance P is a naturally occurring undecapeptide belonging to the tachykinin family of peptides, the latter being so-named because of their prompt contractile action on extravascular smooth muscle tissue. The tachykinins are distinguished by a conserved carboxyl-terminal sequence. In addition to SP the known mammalian tachykinins include neurokinin A and neurokinin B. The current nomenclature designates the receptors for substance P, neurokinin A, and neurokinin B as neurokinin-1 (NK-1), neurokinin-2 (NK-2), and neurokinin-3 (NK-3), respectively. Evidence has been reviewed for the usefulness of tachykinin receptor antagonists in pain, headache, especially migraine, Alzheimer's disease, multiple sclerosis, attenuation of morphine withdrawal, cardiovascular changes, oedema, such as oedema caused by thermal injury, chronic inflammatory diseases such as rheumatoid arthritis, asthma/bronchial hyperreactivity and other respiratory diseases including allergic rhinitis, inflammatory diseases of the gut including ulcerative colitis and Chrohn's disease, ocular injury and ocular inflammatory diseases, proliferative vitreoretinopathy, irritable bowel syndrome and disorders of bladder function including cystitis and bladder detruser hyperreflexia. It has furthermore been suggested that tachykinin receptor antagonists have utility in the following disorders: anxiety, depression, dysthymic disorders, chronic obstructive airways disease, hypersensitivity disorders such as poison ivy, vasospastic diseases such as angina and Reynauld's disease, fibrosing and collagen diseases such as scleroderma and eosinophillic fascioliasis, reflex sympathetic dystrophy such as shoulder/hand syndrome, addiction disorders such as alcoholism, stress related somatic disorders, neuropathy, neuralgia, disorder related to immune enhancement or suppression such as systemic lupus erythmatosus, ophthalmic diseases such as conjunctivitis, vernal conjunctivitis, and the like, and cutaneous diseases such as contact dermatitis, atopic dermatitis, urticaria, and other eczematoid dermatitis.

Method and apparatus for detection of vulnerable atherosclerotic plaque Inventor(s): Casscells, S. Ward III; (Houston, TX), Guo, Bujin; (Houston, TX), Naghavi, Morteza; (Houston, TX), Willerson, James T.; (Houston, TX) Correspondence: Stradling Yocco Carlson & Rauth; Suite 1600; 660 Newport Center Drive; P.O. Box 7680; Newport Beach; CA; 92660; US Patent Application Number: 20040111016 Date filed: August 12, 2003 Abstract: Methods for the detection of inflammation associated with vulnerable atherosclerotic plaque to prevent heart attack and stroke are disclosed. The methods are also applicable to detection of infection, cancer, wounds or auto-immune disease in the body. Certain embodiments of the new methods provide a way of predicting the level of vulnerability of an atherosclerotic plaque to rupture or thrombus formation by assessing via fiber optic NIR spectrophotometry the status of two or more parameters associated with inflamed atherosclerotic plaque in a vessel of a living patient. From these measurements such conditions as low pH, hypoxia, low glucose, oxidative stress or compounds abundant in vulnerable plaque such as oxidized LDL cholesterol and oxidized metabolites of NO, significant active macrophage population, thin plaque cap, as well as senescence and/or apoptosis of smooth muscle or endothelial cells are determined with the assistance of a suitably programmed microprocessor. By considering together the status of some or all of these conditions with respect to successive sites along a vessel wall, particular plaques which are at significant risk of rupturing or thrombosing can be distinguished from "normal" vessel wall and from "intermediate" and relatively stable or "lower risk" plaques. Sites having more of the indicator conditions would be considered most in need of prompt intervention, and certain combinations of parameter levels would be suggestive of relatively stable plaque.Also disclosed is a multi-parameter catheter and analytical processing assembly for use in the methods. Excerpt(s): The present application is a continuation-in-part of U.S. patent application Ser. No. 08/717,449 filed Sep. 20, 1996. The present invention generally relates to methods of diagnosing and treating inflammation, particularly inflamed atherosclerotic plaque at risk of rupture or thrombosis. More particularly, the methods of the invention pertain to the simultaneous detection of two or more chemical parameters associated with inflammation and/or active cellular metabolism in plaque. The invention also relates to multi-parameter catheter assemblies for irradiating sites along a blood vessel wall with near-infrared and visible wavelength radiation and for receiving and analyzing the reflected radiation to qualitatively or quantitatively determine the status of each such parameter. Atherosclerotic coronary artery disease is the leading cause of death in industrialized countries. Typically, patients who have died of coronary disease may exhibit as many as several dozen atherosclerotic plaques in the arterial tree. Plaque, a thickening in the arterial vessel wall, results from the accumulation of cholesterol,

Method for diagnosing lactose intolerance and diagnostic kit for performing the method Inventor(s): Aygen, Sitke; (Koln, DE) Correspondence: Jacobson Holman Pllc; 400 Seventh Street N.W.; Suite 600; Washington; DC; 20004; US Patent Application Number: 20040087837 Date filed: March 19, 2003 Abstract: The method for diagnosing lactose intolerance in patients by the oral administration of defined amounts of lactose, followed by assaying metabolites of lactose, is performed in a way where the lactose administered contains 99%.sup.13Clabeled lactose, preferably from 5 to 30 mg, and after the administration of the lactose, the, content of.sup.13C-labeled lactose is determined in a serum sample taken at a defined time after the administration. A diagnostic kit for performing the method consists of a capsule with from 5 to 30 mg of 99%.sup.13C-labeled lactose, a patient instruction manual, a blood sampling device, sample containers for collecting the blood sample, and optionally a spatula and sample container for a stool specimen. Excerpt(s): The present invention relates to a method for diagnosing lactose intolerance in patients by the oral administration of defined amounts of lactose, followed by assaying metabolites of lactose, and a diagnostic kit for performing the method. Lactose intolerance is a universally very frequent phenomenon and results in a more or less severe digestive disorder from milk and dairy products in the afflicted persons. Lactose intolerance is generally based on the absence of the enzyme lactase for whose formation a gene on chromosome 2 is responsible. This gene determines the time from which humans no longer produce lactase. Depending on the ethnic origin, this can be the case sooner or later. In earlier times of evolution, humans, like many other mammals, lost the enzyme always when they were no longer fed with breast milk (cf. Pharm. Ztg. No. 9, 145th annual volume, Mar. 2, 2000). Today, the H.sub.2 breath test is employed most frequently for diagnosing lactose intolerance since it is simple and telling. Thus, the patient drinks a solution of 50 g lactose in water. The hydrogen subsequently exhaled is then measured repeatedly by gas chromatography over 4 hours. Thus, not only qualitative, but also quantitative information about the lactase deficiency is obtained. Lactose intolerance is now considered a disease which can be treated only symptomatically to date. However, in the meantime, there has been found a possibility of ingesting the enzyme lactase in the form of capsules, tablets or solution and thus compensating the lactase deficiency.

Methods and agents for treating cardiovascular diseases Inventor(s): Borlak, Jurgen; (Lehrte, DE), Thum, Thomas; (Hannover, DE) Correspondence: Kurt Briscoe; Norris, Mclaughlin & Marcus, P.A.; 220 East 42nd Street, 30th Floor; New York; NY; 10017; US Patent Application Number: 20040110733 Date filed: December 4, 2002 Abstract: This invention relates to a method and an agent for treating cardiovascular diseases, especially cardiac hypertrophy, wherein said method and agent consist in increasing testosterone concentration in pathological tissues to normal levels or inhibiting and/or eliminating metabolites from testosterone metabolism.The testosterone concentration in pathological tissues can be increased to normal levels by administering at least one substance from the following groups:testosterone;substances with effects similar to those of testosterone;testosterone mimetics;substances that enhance testosterone synthesis;substances that inhibit testosterone metabolism.Metabolites from testosterone metabolism can be inhibited and/or eliminated by administering at least one substance from the following groups:substances that bind to the androgen receptor, causing the receptor levels to be regulated and thus normalized;substances that bind to the androgen receptor, regulating the androgen receptor-mediated gene expression by inhibiting it, as is observed in cardiac hypertrophy.Areas of application are medicine and pharmaceuticals industry. Excerpt(s): This invention relates to methods and agents for treating cardiovascular diseases, especially cardiac hypertrophy. Areas of application are medicine and pharmaceuticals industry. Both spermatogenesis and androgen secretion are controlled by hormones of the anterior lobe of the pituitary gland; together with androgens folliclestimulating hormones (FSHs) promote spermatogenesis by supporting the function of Sertoli cells. Luteinizing hormones (LHs) affect the Leydig cells and stimulates androgen release. These secreted androgens have an inhibiting effect both on the release of FSHs and on that of LHs. The relatively slight inhibiting effect of these androgens is supported by estradiol, which is synthesized in the testis and converted from testosterone in the peripheral tissues. Injections of testosterone into the hypothalamus cause testicular atrophy and a decrease in secretion of a joint releasing hormone for FSH and LH. Androgen release is strongly inhibited by estrogens and, to a lesser extent, by progestogens. Via a feedback mechanism, they inhibit the release of gonadotropic hormones. Lack of FSHs thus leads to an interruption of spermatogenesis, and deficiency of LHs stops androgens secretion. In other words, administration of estrogens to men has an effect similar to that of surgical castration, only that it is caused by hormones. In order to avoid the effects of androgens, chemically synthesized antiandrogens are used as receptor blocker. Due to their structure, which is similar to that of testosterone, they can bind to the androgen receptor, inhibiting the signal transduction mediated by the androgen receptor. Known blockers are cyproteron and cyproteron acetate. Under the influence of antiandrogens, development of the seminal duct and its accessory glands as well as the penis is inhibited. In addition, differentiation of the normal phenotype into the male phenotype in the hypothalamus is blocked. In adult animals, antiandrogens inhibit spermatogenesis as well as seminal vesicle and cause prostate and oil gland atrophy. Furthermore, antiandrogens increase secretion of FSH- and LH-releasing hormones and thus also release of FSHs and LHs. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Methods of optimizing drug therapeutic efficacy for treatment of immune-mediated gastrointestinal disorders Inventor(s): Seidman, Ernest G.; (Luc, CA), Theoret, Yves; (Montreal, CA) Correspondence: Cathryn Campbell; Mcdermott, Will & Emery; 7th Floor; 4370 LA Jolla Village Drive; San Diego; CA; 92122; US Patent Application Number: 20040097527 Date filed: November 6, 2003 Abstract: The present invention provides a method of optimizing therapeutic efficacy and reducing toxicity associated with 6-mercaptopurine drug treatment of an immunemediated gastrointestinal disorder such as inflammatory bowel disease. The method of the invention includes the step of determining the level of one or more 6mercaptopurine metabolites in the patient having an immune-mediated gastrointestinal disorder. Excerpt(s): This application claims the benefit of priority of provisional application serial No. 60/101,714, filed Sep. 24, 1998, which is incorporated herein by reference. The present invention relates generally to autoimmunity and immune-mediated gastrointestinal disorders such as inflammatory bowel disease and more specifically to methods for optimizing treatment of immune-mediated gastrointestinal disorders. Immune-mediated gastrointestinal disorders encompass a wide range of debilitating gastrointestinal diseases of various etiologies. One such immune-mediated gastrointestinal disorder, inflammatory bowel disease (IBD), is the collective term used to describe two gastrointestinal disorders of unknown etiology: Crohn's disease (CD) and ulcerative colitis (UC). The course and prognosis of IBD, which occurs world-wide and is reported to afflict as many as two million people, varies widely. Onset of IBD is predominantly in young adulthood with diarrhea, abdominal pain, and fever the three most common presenting symptoms. The diarrhea may range from mild to severe and in ulcerative colitis often is accompanied by bleeding. Anemia and weight loss are additional common signs of IBD. Ten percent to fifteen percent of all patients wits IBD will require surgery over a ten year period. In addition, patients with IBD are at increased risk for the development of intestinal cancer. Reports of an increasing occurrence of psychological problems, including anxiety and depression, are perhaps not surprising symptoms of what is often a debilitating disease that strikes people in the prime of life.

Another objective of the present invention is an application of monoterpenes in inhibition of cell growth and metastasis control of primary tumors being applied in vitro and in vivo gliomas cell lines C6 and U 87 and A172. Further another objective of the present invention refers to a specific methods for applying the composition with chemopreventive and chemotherapeutic effects in humans and animals showing malignant neoplasias by inhalation and nebulization treatment, oral and intratumoral, followed or not by radiotherapy with dilutions from 0,03% to 30% of the monoterpene perillyl or its derived metabolites diluted in the solvents specified by the usual techniques. Excerpt(s): The present invention relates to treatment for mammalian nervous system cell tumors. In particular, the present invention relates to using of monoterpene perillyl alcohol to inhibit tumor formation and to cause tumor regression. The progress in treating most common solid malignancies has slowed due at least in part to the lack of new effective agents. This has led to a new emphasis on cancer prevention and on developing therapeutic agents with novel mechanisms. Recent data suggest that monoterpenes, a class of non-toxic compounds that act through novel mechanism, may be useful for both chemoprevention and treatment of cancer. These compounds have been shown to exert chemopreventive and chemotherapeutic activities in several tumor models and represent a new class of cancer therapeutic agents.

The compounds are N-aryl
Patents 205
diazaspirocyclic compounds, bridged analogs of N-heteroaryl diazaspirocyclic compounds, or prodrugs or metabolites of these compounds. The aryl group can be a five- or six-membered heterocyclic ring (heteroaryl). The compounds and compositions can be used to treat and/or prevent a wide variety of conditions or disorders, particularly those disorders characterized by dysfunction of nicotinic cholinergic neurotransmission, including disorders involving neuromodulation of neurotransmitter release, such as dopamine release. CNS disorders, which are characterized by an alteration in normal neurotransmitter release, are another example of disorders that can be treated and/or prevented. The compounds and compositions can also be used to alleviate pain. The compounds can: (i) alter the number of nicotinic cholinergic receptors of the brain of the patient, (ii) exhibit neuroprotective effects and (iii) when employed in effective amounts, not result in appreciable adverse side effects (e.g., side effects such as significant increases in blood pressure and heart rate, significant negative effects upon the gastro-intestinal tract, and significant effects upon skeletal muscle). Excerpt(s): This document claims priority to and the benefit of the filing date of copending provisional application entitled "N-Aryl Diazaspiracyclic Compounds and Methods of Preparation and Use Thereof" assigned serial No. 60/394,337, and filed Jul. 5, 2002, which is hereby incorporated by reference. The present invention relates to pharmaceutical compositions incorporating compounds capable of affecting nicotinic cholinergic receptors, for example, as modulators of specific nicotinic receptor subtypes. The present invention also relates to methods for treating a wide variety of conditions and disorders, particularly those associated with dysfunction of the central and autonomic nervous systems. Nicotine exhibits a variety of pharmacological effects (Pullan et al., N. Engl. J. Med. 330:811-815 (1994)), some of which are due to neurotransmitter release (See, for example, Sjak-shie et al., Brain Res. 624:295 (1993), where neuroprotective effects of nicotine are proposed). For example, acetylcholine, dopamine, norepinephrine, serotonin and glutamate are released by neurons upon administration of nicotine (Rowell et al., J. Neurochem. 43:1593 (1984); Rapier et al., J. Neurochem. 50:1123 (1988); Sandor et al., Brain Res. 567:313 (1991) and Vizi, Br. J. Pharmacol. 47:765 (1973), (Hall et al., Biochem. Pharmacol. 21:1829 (1972), (Hery et al., Arch. Int. Pharmacodyn. Ther. 296:91 (1977)), and Toth et al., Neurochem Res. 17:265 (1992)). Confirmatory reports and additional recent studies show that nicotine administration modulates glutamate, nitric oxide, GABA, takykinins, cytokines and peptides in the central nervous system (CNS) (reviewed in Brioni et al., Adv. Pharmacol. 37:153 (1997)). Nicotine also reportedly potentiates the pharmacological behavior of certain pharmaceutical compositions used to treat certain disorders. See, for example, Sanberg et al., Pharmacol. Biochem. & Behavior 46:303 (1993); Harsing et al., J. Neurochem. 59:48 (1993) and Hughes, Proceedings from Intl. Symp. Nic. S40 (1994). Various additional beneficial pharmacological effects of nicotine have been proposed. See, for example, Decina et al., Biol. Psychiatry 28:502 (1990); Wagner et al., Pharmacopsychiatry 21:301 (1988); Pomerleau et al., Addictive Behaviors 9:265 (1984); Onaivi et al., Life Sci. 54(3):193 (1994); Tripathi et al., J.

invention further relates to the novel cytochrome P450 as well as to vectors, host cells and antibodies to the polypeptide and the recombinant methods for producing the same. Uses and methods relating to any of the foregoing are also included within the scope of the invention. The cytochromes P450 comprise a large gene superfamily that encodes over 500 distinct heme-thiolate proteins that catalyze the oxidation of drugs and numerous other compounds in the body [Nelson et al., (1996); Guengerich (1991)]. Since there are at least 500 different cytochrome P450 enzymes, it is of considerable interest in the pharmaceutical and other fields to identify which of these enzymes are most important in the metabolism of individual compounds. There are now numerous examples of adverse drug-drug interactions and side effects that can now be understood in terms of the cytochrome P450 enzymes.

Polyamine-mediated transfection Inventor(s): Bennett, Michael; (El Sobrante, CA), Lizarzaburu, Mike E.; (San Mateo, CA), Nantz, Michael H.; (Davis, CA), Niedzinski, Edmund J.; (Vacaville, CA) Correspondence: Townsend And Townsend And Crew, Llp; Two Embarcadero Center; Eighth Floor; San Francisco; CA; 94111-3834; US Patent Application Number: 20040077888 Date filed: May 30, 2003 Abstract: The present invention provides cationic lipids and methods that facilitate nucleic acid delivery and which also yield biologically benign metabolites following transfection. The compounds are lipidic polyamines that use a pentaerythritol scaffold to link different hydrophobic and DNA-binding domains. Excerpt(s): This application claims priority to U.S. Provisional Patent Application Nos. 60/385,234 and 60/384,514, both filed on May 31, 2002, the disclosures of which are hereby incorporated by reference in their entireties for all purposes. The development of new cationic lipids as vehicles for the intracellular delivery of gene pharmaceuticals continues to be a promising field of research (see, Miller, A. D., Angew. Chem. Int. Ed., 37:1768-1785 (1998)). Since Felgner's first report (see, Feigner et al., Proc. Natl. Acad. Sci. USA., 84:7413-7417 (1987)) of cationic lipid-mediated DNA delivery, dramatic improvements in lipid-based gene delivery systems have led to numerous clinical applications (see, Martin, P., J. Gene Med., 3:91-92 (2001)). Despite recent successes in non-viral gene therapy, cytotoxicity and low transfection activity continue to plague most lipid-based gene delivery systems (see, Byk et al., European Opin. Ther. Patents, 8:1125-1141 (1998)). Overcoming these obstacles is crucial for successful application of this technology, particularly in cases that involve repeat dosing. One particular approach to ameliorate the effects of lipid-associated cytotoxicity is the design and synthesis of degradable cationic lipids. Lipids may be engineered to degrade in response to a number of physiological conditions, such as changes in pH (see, Zhu et al, J. Am. Chem. Soc., 122:2645-2646 (2000); Gerasimov et al., Biochim. Biophys. Acta., 1324:200214 (1997)) or enzymatic activity (see, Litzinger et al., Biochim. Biophys. Acta., 1113:201227 (1992)). A cationic lipid that slowly degrades to non-toxic metabolites after facilitating the cellular incorporation of DNA would avoid the potential side effects that might result from the cumulative concentration of intracellular cationic lipids. The development of cationic lipids that both facilitate DNA delivery and also yield biologically benign metabolites following DNA transfection would thus be advantageous (see, Byk et al., J. Med. Chem., 43:4377-4387 (2000); Tang et al., Biochem.
Patents 209
Biophys. Res. Commun., 242:141-145, (1998)). Previous research has explored the relationship between the chemical structure of cationic lipids and the influences on nonviral gene transfection (see, Wu et al., Bioconjugate Chem., 12:251-257 (2001); Bennett et al., J. Med. Chem., 40:4069-4078 (1997)). In one such study, pentaerythritol derivatives containing.alpha.-ammonium ester headgroups exhibited low cytotoxicity in transfection experiments (see, Aberle et al., Biochemistry, 37:6533-6540). As postulated, the metabolism of these compounds was accelerated by facile hydrolysis of the.alpha.ammonium esters, giving rise to non-toxic metabolites.

Polyhydroxyalkanoate production from polyols Inventor(s): Peoples, Oliver P.; (Arlington, MA), Skraly, Frank A.; (Somerville, MA) Correspondence: Patrea L. Pabst; Holland & Knight Llp; Suite 2000, One Atlantic Center; 1201 West Peachtree Street, N.E.; Atlanta; GA; 30309-3400; US Patent Application Number: 20040023347 Date filed: May 21, 2003 Abstract: Organisms are provided which express enzymes such as glycerol dehydratase, diol dehydratase, acyl-CoA transferase, acyl-CoA synthetase.beta.-ketothiolase, acetoacetyl-CoA reductase, PHA synthase, glycerol-3-phosphate dehydrogenase and glycerol-3-phosphatase, which are useful for the production of PHAs. In some cases one or more of these genes are native to the host organism and the remainder are provided from transgenes. These organisms produce poly (3-hydroxyalkanoate) homopolymers or co-polymers incorporating 3-hydroxypropionate or 3-hydroxyvalerate monomers wherein the 3-hydroxypropionate and 3-hydroxyvalreate units are derived from the enzyme catalysed conversion of diols. Suitable diols that can be used include 1,2propanediol, 1,3 propanediol and glycerol. Biochemical pathways for obtaining the glycerol from normal cellular metabolites are also described. The PHA polymers are readily recovered and industrially useful as polymers or as starting materials for a range of chemical intermediates including 1,3-propanediol, 3-hydroxypropionaldehyde, acrylics, malonic acid, esters and amines. Excerpt(s): Priority is claimed to U.S. provisional application Serial No. 60/095,329 filed Aug. 4, 1998. This is generally in the field of production of polyhydroxyalkanoates by genetic engineering of bacterial enzymes. Numerous microorganisms have the ability to accumulate intracellular reserves of poly [(R)-3-hydroxyalkanoate] (PHA) polymers. PHAs are biodegradable and biocompatible thermoplastic materials with a broad range of industrial and biomedical applications (Williams and Peoples, 1996, CHEMTECH 26: 38-44). PHAs can be produced using a number of different fermentation process and recovered using a range of extraction techniques (reviewed by Braunegg et al. 1998, J. Biotechnol. 65: 127-161; Choi and Lee, 1999). Plant crops are also being genetically engineered to produce these polymers offering a cost structure in line with the vegetable oils and direct price competitiveness with petroleum-based polymers (Williams and Peoples 1996, CHEMTECH 26:38-44; Poirier, Y. 1999, Plant Biotechnology pp. 181-185). PHAs are formed by the action of a PHA synthase enzyme. As the polymer chains grow, they form insoluble granules. The PHAs can then be recovered and then converted into chemicals or converted into chemicals during the recovery process (Martin et al. PCT WO 97/15681). Therefore, in addition to their utility as polymers, the PHAs represent a unique mechanism for storing new chemistries in both microbial and plant crop systems.

Metabolites
Abstract: The present invention provides a system and method for testing the neuronal effects of a compound and its metabolites. The system (100) includes a microelectrode array (102), a data capture unit (108) communicably coupled to the microelectrode array (104), a processor (110) communicably coupled to the data capture unit (108) and one or more input/output devices (112) communicably coupled to the processor (110). The microelectrode array (102) is capable of supporting genetically modified neuronal cells (104) and measuring neuronal activity. The testing medium containing the compound and the metabolites is extracted from hepatocyte cells (106). The method (400) determines the effects of the metabolites of a sample compound on neuronal cells by exposing a sample compound to hepatocyte cells (406), extracting medium from the exposed cells (408) and exposing the extracted medium to neuronal cells on a microelectrode array (410). The effects of a sample compound and its metabolites versus the effects of a sample compound alone can be determined from a comparison of the data (406). Excerpt(s): The present invention relates in general to the field of action potential analysis, and more particularly, to the use of advanced neuronal networks detection techniques for the detailed analysis of neuronal signal transduction pathways and their use for large-scale reproducible analysis. This application claims priority to U.S. Provisional Patent Application Serial No. 60/430,409, filed Dec. 2, 2002. Without limiting the scope of the invention, the background of the invention is described in connection with the recording and analysis of neuronal action potentials using substrate integrated, thin film electrodes, as an example. The first recordings of neuronal action potentials using substrate integrated, thin film electrodes were made as early as 1977 (Gross, et al. 1977). Subsequent research has led to multi-channel investigations of network dynamics and their applications. Indium-tin oxide was introduced later as a viable microelectrode material and was designed and tested for recording in life support chambers (Gross and Schwalm, 1995). These networks were used to explore stimulation of networks through the recording electrodes (Gross et al., 1994). Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

develops from changes in the DNA, or genetic material, of the body's cells, causing them to develop into precancerous lesions. Such lesions exhibit a strong tendency to develop into malignant tumours, or cancer. Such lesions include lesions of the breast (that can develop into breast cancer), lesions of the skin (that can develop into malignant melanoma or basal cell carcinoma), colonic adenomatous polyps (that can develop into colon cancer), and other such neoplasms. Cancer may take years to develop. The process typically begins with some disruption to the DNA of a cell, the genetic code that directs the life of the cell. Many things, such as diet, tobacco, sun exposure or certain chemicals can cause such disruptions. Some cells will enter a precancerous phase, known as dysplasia. Some cells will also enter the state of carcinoma in situ, in which the cancer cells are restricted to a microscopic site and do not pose a great threat. Eventually, unless the body's own immune system takes care of the wayward cells either on its own or by being enhanced by specific chemicals, a tumour will develop. It may take as long as 30 years for a tumour to go through the entire process and become large enough to produce clinical symptoms. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

The principal use of a sedative-hypnotic drug is to produce drowsiness and to promote sleep. Since sedative-hypnotic drugs usually have the capacity of producing widespread depression of the CNS, these drugs are employed for various reasons, including as antiepileptic, muscle relaxants, antianxiety drugs, and even to produce amnesia or general anesthesia. Throughout the world, more prescriptions are written for sedativehypnotic-antianxiety drugs than for any other class of drugs. Barbiturates have enjoyed a long period of extensive use as sedative-hypnotic drugs. However, except for a few specialized uses, they have been largely replaced by the somewhat safer benzodiazepines.

Use of genes encoding membrane transporter pumps to stimulate the production of secondary metabolites in biological cells Inventor(s): Goossens, Alain; (Lokeren, BE), Inze, Dirk Gustaaf; (Moorsel-Aalst, BE) Correspondence: Trask Britt; P.O. Box 2550; Salt Lake City; UT; 84110; US Patent Application Number: 20040064849 Date filed: September 18, 2003 Abstract: The invention relates to the field of secondary metabolite production in plants and plant cell cultures. More specifically, the invention relates to the use of transporters and more particularly ABC-transporters to enhance the production and/or secretion of secondary metabolites in plants and plant cell cultures. Excerpt(s): This application is a continuation of PCT International Patent Application No. PCT/EP/02/04322, filed on Apr. 18, 2002, designating the United States of America, and published, in English, as PCT International Publication No. WO 02/083888 A2 on Oct. 24, 2002, the contents of the entirety of which is incorporated by this reference. The invention relates generally to biotechnology, and more specifically to the field of secondary metabolite production in plants and plant cell cultures. Particularly, the invention relates to the use of transporters and more particularly ABCtransporters to enhance the production and/or secretion of secondary metabolites in plants and plant cell cultures. Higher plants are able to produce a large number of small-molecularweight compounds with very complex structures. These compounds, called "secondary metabolites", can play a role in the resistance against pests and diseases, attraction of pollinators and interaction with symbiotic microorganisms. Besides the importance for the plant itself, secondary metabolites are of great commercial interest because they determine the quality of food (color, taste, and aroma) and ornamental plants (flower color, smell). A number of secondary metabolites isolated from plants are commercially available as fine chemicals, for example, drugs, dyes, flavours, fragrances and even pesticides. In addition, various health improving effects and disease preventing activities of secondary metabolites have been discovered, such as anti-oxidative and antimetastatic-lowering properties (e.g., vinblastine, taxol).

[email protected] Website: www.elsevierhealth.com. PRICE: $199.00. ISBN: 723432589. Summary: Diet and nutrition play an integral role in the management of individuals with renal (kidney) disease. Abnormalities associated with chronic renal disease include retention of nitrogenous metabolites, a decreased ability to regulate levels of electrolytes and water, and certain vitamin deficiencies. Dietary intake can play a crucial role in managing these abnormalities. Interest in the nutritional status of patients with renal failure has increased with the understanding that poor nutrition predicts a poor outcome. This chapter on nutrition in chronic renal (kidney) failure (CRF) is from a comprehensive textbook that covers every clinical condition encountered in nephrology (the study of kidney disease). The author of this chapter discusses malnutrition, assessment of nutritional status, nutritional guidelines, monitoring and treatment, including the use of oral supplementation, tube feeding, supplementation of dialysate fluids, and appetite stimulants and growth factors. The author concludes that indices of malnutrition are powerful predictors of mortality in end stage renal disease (ESRD). The high prevalence of protein-energy malnutrition in this group is clearly related to multiple factors encountered both before and after renal replacement therapy (dialysis) has commenced. The chapter is clinically focused and extensively illustrated in full color. 8 figures. 4 tables. 28 references.

Summary: The absorption of drugs into the body most often involves passive diffusion through lipid membranes, usually via the digestive tract but occasionally through the skin or lungs. Most drugs that gain entry into the body would remain there for a very long time if it were not for the body's ability to convert (metabolize) drugs into more water-soluble and hence more readily excreted, metabolites. The liver is the major organ involved in drug metabolism. For some xenobiotics, the small intestine also plays a major role. This chapter on drug metabolism in the liver and intestines is from a lengthy, two-volume textbook that integrates the various demands of science, technology, expanding information, good judgment, and common sense into the diagnosis and management of gastrointestinal patients. Topics include general principles, the discovery of drug-metabolizing enzymes, P450s and drug metabolism, phase 2 enzymes, and the role of transporters. 4 figures. 3 tables. 139 references.

Summary: This chapter on the nutritional management of nondialyzed patients with chronic renal failure (CRF) is from a medical textbook on nutrition and metabolism of individuals with renal disease or renal failure. The author stresses that the patient with CRF has alterations in both the dietary requirements and tolerance for most nutrients. Causes of these disorders include decreased (or occasionally increased) urinary, intestinal, and dermal excretion and intestinal absorption. Causes may also include altered metabolism of individual nutrients or their metabolites or products. The author also notes that the nutritional status of the patient undergoing maintenance hemodialysis or peritoneal dialysis is a strong predictor of morbidity and mortality. Other topics include training and monitoring the patient undergoing dietary therapy; dietary therapy for patients who are not yet receiving dialysis therapy, including recommended nutrient intakes; management of the patient with diabetic nephropathy; nutritional management during catabolic stress; and the use of growth factors. Detailed guidelines are provided for patient care management. 4 figures. 3 tables. 270 references. (AA-M).

Metabolites
Summary: This chapter on uremic toxicity is from a medical textbook on nutrition and metabolism of individuals with renal disease or renal failure. The author defines uremia as a toxic syndrome caused by severe glomerular insufficiency, associated with disturbances in tubular and endocrine functions of the kidney. It is characterized by retention of toxic metabolites associated with changes in volume and electrolyte composition of the body fluids and excess or deficiency of various hormones. The longterm survival of patients with end-stage renal disease (ESRD) on maintenance hemodialysis is strong evidence that some of the most important uremic toxins are dialyzable. The author notes that in acute as well as in chronic renal failure, severe glomerular insufficiency is always associated with secondary disturbances in tubular functions, which may explain such aspects of uremia as hyperkalemia and metabolic acidosis. The author outlines the symptoms and signs of uremia, the toxic effects of uremic plasma or serum, factors that influence uremic toxicity, and the toxicity of specific substances in uremia. 1 table. 860 references.

Summary: This chapter, from an extensive desk reference book about the clinical evaluation and diagnosis of renal disease in children, discusses the role of the chemistry laboratory in the clinical study of renal disease. Eight sections cover: recent changes in laboratory technology; reference intervals; pediatric specimens; electrolytes, fluid, and acid-base balance; other inorganic analytes; glucose and metabolites; nitrogenous compounds; and proteins. The author notes that the improved accuracy of micromethods, such as the widespread use of enzymes as diagnostic reagents for more specific measurements of substrates like glucose and uric acid, has greatly reduced potential interferences from both drugs and endogenous metabolites. Current automation allows any laboratory, whether in a children's hospital or in a facility serving both adult and pediatric patients, to perform rapid, precise microchemical determinations. 22 references.

PRICE: $59.95 for members, $70.00 for nonmembers. ISBN: 0880911530. Summary: This section outlining guidelines for nutritional support in renal failure is from a manual that serves as a nutrition care guide for dietetics professionals, physicians, nurses, and other health professionals. The manual integrates current knowledge of nutrition, medical science, and food to set forth recommendations for healthy individuals and those for whom medical nutrition therapy (MNT) is indicated. The goal of nutrition support in renal failure is to achieve or maintain optimal nutritional status and preserve remaining kidney function through alterations in fluid, protein, and electrolyte intake. Nutrition support is used for patients with acute or chronic renal failure who are unable to meet nutrient requirements by oral intake. Impaired kidney function results in altered filtration, reabsorption, and excretion of metabolites and diminished urinary output. Hormonal function is also affected and

may cause impaired vitamin D activation, impaired red blood cell synthesis, and glucose intolerance. The alterations differ with the cause of renal impairment; therefore, sodium, potassium, blood urea nitrogen (BUN), phosphate, urinary output, and the presence of acidosis must be monitored. The text notes the purpose, use, modifications, and adequacy of the diet. A separate section discusses enteral and parenteral nutrition, continuous arteriovenous hemofiltration, and the use of modified formulas (essential amino acids). 3 tables. 57 references. (AA-M). •

Summary: To avoid toxicity from either parent drugs or active metabolites, the doses of many drugs must be adjusted downward in patients with decreased renal insufficiency. This chapter, from a medical text on the therapy of renal disease and related disorders, discusses the principles of drug dosing as a framework for dosing regimen adjustments in patients with renal insufficiency. The authors offer dosing guidelines for patients with various degrees of renal dysfunction, including dialysis. 2 figures. 4 tables. 23 references.

CHAPTER 8. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for metabolites. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a nonprofit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI Advice for the Patient can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with metabolites. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.). The

Commercial Databases In addition to the medications listed in the USP above, a number of commercial sites are available by subscription to physicians and their institutions. Or, you may be able to access these sources from your local medical library.
Mosby’s Drug Consult Mosby’s Drug Consult database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/.
PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee. If you have any questions about a medical treatment, the FDA may have an office near you. Look for their number in the blue pages of the phone book. You can also contact the FDA through its toll-free number, 1-888-INFO-FDA (1-888-463-6332), or on the World Wide Web at www.fda.gov.

Coffee Break: Tutorials for Biologists19 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.20 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.21 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
19 Adapted 20
from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 21 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.
241
APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on metabolites can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to metabolites. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to metabolites. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “metabolites”:
242
Metabolites
Dietary Supplements http://www.nlm.nih.gov/medlineplus/dietarysupplements.html Environmental Health http://www.nlm.nih.gov/medlineplus/environmentalhealth.html Genetic Brain Disorders http://www.nlm.nih.gov/medlineplus/geneticbraindisorders.html Heart Failure http://www.nlm.nih.gov/medlineplus/heartfailure.html Leukodystrophies http://www.nlm.nih.gov/medlineplus/leukodystrophies.html Medicines http://www.nlm.nih.gov/medlineplus/medicines.html Metabolic Disorders http://www.nlm.nih.gov/medlineplus/metabolicdisorders.html You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The NIH Search Utility The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to metabolites. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information. The following is a representative sample: •

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to metabolites. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with metabolites. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about metabolites. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “metabolites” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “metabolites”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format
244
Metabolites
option “Organization Resource Sheet.” Type “metabolites” (or synonyms) into the “For these words:” box. You should check back periodically with this database since it is updated every three months. The National Organization for Rare Disorders, Inc. The National Organization for Rare Disorders, Inc. has prepared a Web site that provides, at no charge, lists of associations organized by health topic. You can access this database at the following Web site: http://www.rarediseases.org/search/orgsearch.html. Type “metabolites” (or a synonym) into the search box, and click “Submit Query.”

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.22
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.
