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 losartan 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 losartan, 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 losartan, 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 losartan. 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 losartan, 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.

CHAPTER 1. STUDIES ON LOSARTAN Overview In this chapter, we will show you how to locate peer-reviewed references and studies on losartan.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and losartan, 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 “losartan” (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: •
Effects of Losartan on Renal and Cardiovascular Outcomes in Patients with Type 2 Diabetes and Nephropathy Source: New England Journal of Medicine. 345(12): 861-869. September 20, 2001. Summary: Diabetic nephropathy (diabetes associated kidney disease) is the leading cause of end stage renal disease (ESRD). Interruption of the renin angiotensin system slows the progression of renal (kidney) disease in patients with type 1 diabetes, but similar data are not available for patients with type 2, the most common form of diabetes. This article reports on a study that assessed the role of the angiotensin II receptor antagonist losartan in patients with type 2 diabetes and nephropathy. A total of 1,513 patients were enrolled in this randomized, double blind study comparing losartan (50 to 100 milligrams once daily) with placebo, both taken in addition to conventional antihypertensive treatment (calcium channel antagonists, diuretics, alpha blockers, beta

Losartan
blockers, and centrally acting agents) for a mean of 3.4 years. The primary outcome was the composite of a doubling of the baseline serum creatinine concentration, end stage renal disease, or death. Secondary end points included a composite of morbidity (related illness or complications) and mortality from cardiovascular causes, proteinuria, and the rate of progression of renal disease. A total of 327 patients in the losartan group reached the primary end point, as compared with 359 in the placebo group. Losartan reduced the incidence of a doubling of the serum creatinine concentration and end stage renal disease, but had no effect on the rate of death. The benefit exceeded that attributable to changes in blood pressure. The composite of morbidity and mortality from cardiovascular causes was similar in the two groups, although the rate of first hospitalization for heart failure was signficantly lower with losartan. The level of proteinuria (protein in the urine) declined by 35 percent with losartan. The authors conclude that losartan conferred significant renal benefits in patients with type 2 diabetes and nephropathy, and it was generally well tolerated. 3 figure. 3 tables. 34 references. •
Low-Sodium Diet Potentiates the Effects of Losartan in Type 2 Diabetes Source: Diabetes Care. 25(4): 663-671. April 2002. Contact: Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website: www.diabetes.org. Summary: Patients with diabetes have a high prevalence of hypertension (high blood pressure), increased total body exchangeable sodium levels, and an impaired ability to excrete a sodium load. This article reports on a study that assessed the effect of dietary sodium (salt) restriction on the efficacy of losartan in subjects with hypertension (high blood pressure), type 2 diabetes, and albumin (protein) excretion rates of 10 to 200 micrograms per minute. In the study, 20 subjects were randomized to losartan 50 milligrams per day (n = 10) or placebo (n = 10). Drug therapy was given in two 4 week phases separated by a washout period. In the last 2 weeks of each phase, patients were assigned to low or regular sodium diets, in random order. The results showed that a low-sodium diet dominates the antihypertensive and antiproteinuric effects of losartan in type 2 diabetes. The blood pressure reduction resulting from the addition of a low sodium diet to losartan was of similar magnitude to that predicted from the addition of a second antihypertensive agent. Thus, the low sodium diet optimizes the renoprotective (protective of the kidney) effects of the ANG-receptor blocker, losartan. In certain circumstances, the addition of a low-sodium diet should be considered as an appropriate alternative to additional pharmacological antihypertensive agents, including combination therapy with a diuretic. 5 figures. 4 tables. 41 references.

Losartan Reduces the Costs Associated With Diabetic End-Stage Renal Disease Source: Diabetes Care. 26(3): 683-687. March 2003. Contact: Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website: www.diabetes.org. Summary: This article reports on a study undertaken to evaluate the within-trial effect of losartan and conventional antihypertensive therapy (CT) compared with placebo and CT on the economic cost associated with end stage renal disease (ESRD). The study was a multinational double-blind randomized placebo-controlled clinical trial designed to evaluate the renal protective effects of losartan on a background of CT in patients with type 2 diabetes and nephropathy (kidney disease). The primary composite end point was doubling of serum creatinine, ESRD, or death. The results showed that losartan and

CT compared with placebo and CT reduced the number of days with ESRD by 33.6 days per patient over 3.5 years. This reduction in ESRD days resulted in a decrease in cost associated with ESRD of $5,144 per patient. After accounting for the cost of losartan, the reduction in ESRD days resulted in a net savings of $3,522 per patient over 3.5 years. The authors conclude that treatment with losartan in patients with type 2 diabetes and nephropathy not only reduced the incidence of ESRD, but also resulted in substantial cost savings. 1 figure. 4 tables. 13 references.
Federally Funded Research on Losartan The U.S. Government supports a variety of research studies relating to losartan. 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 losartan. 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 losartan. The following is typical of the type of information found when searching the CRISP database for losartan: •

Preliminary data from the Reduction in Endpoints in NIDDM with the Angiotensin II Antagonist Losartan (RENAAL) trial indicate that anemia is a modifiable risk factor for ESRD and CV morbidity and mortality in type 2 DN. I hypothesize that hemoglobin (Hb) is an independent predictor of both renal and CV disease in this population. The specific aims of this project are to determine if anemia is an independent predictor of 1) ESRD; 2) cardiovascular morbidity (non-fatal CV events defined as hospitalization for heart failure, myocardial infarction, and unstable angina, and mortality (sudden cardiac death, death due to progressive heart failure, myocardial infarction, and other cardiac causes) and 3) hospitalization for revascularization (coronary, peripheral, cerebral, or renal), amputation, and stroke. I will use the RENAAL trial database involving 1,513 Type 2 diabetic patients with nephropathy followed on average for 3.4 years. Cox proportional hazards regression models using baseline and follow-up (Hb) will be employed as the independent variable, and renal 2

Power analysis based on observed event rates in the RENAAL trial indicate 95% power to detect a 30% reduction in risk of the primary composite endpoint of doubling serum creatinine, ESRD or death for patients in the highest compared to the lowest quartile of baseline Hb. I expect these results will establish anemia as an independent risk factor for ESRD and cardiovascular morbidity and mortality in type 2 diabetics with progressing renal disease. These data could change practice and lead to new clinical trials. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Principal Investigator & Institution: Lombard, Julian H.; Medical College of Wisconsin Po Box26509 Milwaukee, Wi 532260509 Timing: Fiscal Year 2003; Project Start 01-MAR-2003; Project End 28-FEB-2008 Summary: Elevated dietary salt intake in normotensive animals leads to impaired relaxation of resistance arteries in response to a variety of vasodilator stimuli. This appears to be mediated by suppression of the renin-angiotensin system (RAS), since it can be prevented by i.v. infusion of a low dose of angiotensin II (ANGII). This project will study the response of the middle cerebral artery (MCA) to vasodilator stimuli in four novel inbred genetic rat strains: 1) Dahl salt sensitive (Dahl S; SS/Mcw) rats, a genetic model of salt sensitive hypertension that exhibits impaired relaxation to vasodilator stimuli and an impaired ability to regulate plasma ANGII levels in response to changes in dietary salt intake; 2) normotensive Brown Norway (BN/Mcw) rats; 3) SS.BN13 consomic rats, with chromosome 13 of BN rat on the Dahl S background; and 4), renin congenic rats, with the Dahl R renin gene on the Dahl S genetic background. These rat strains will be used to test two fundamental hypotheses related to the role of ANGII in maintaining normal vascular relaxation mechanisms. The first hypothesis is that ANGII, acting through its specific receptor subtypes, plays a role in the maintenance of vascular relaxation mechanisms in middle cerebral arteries under normal physiological conditions. The second hypothesis is that the impaired relaxation of the middle cerebral artery to vasodilator stimuli that occurs in Dahl S rats on a low salt diet is due to defective regulation of plasma ANGII levels in these animals. In Aim 1, we will compare the response of isolated middle cerebral arteries to a variety of vasodilator stimuli acting via different signal transduction mechanisms in inbred normotensive BN/Mcw rats, SS/Mcw rats, and SS.BN13 consomic rats on a low salt diet, in order to demonstrate that SS/Mcw rats on low salt diet exhibit impaired relaxation mechanisms that are not shared by BN/Mcw rats, SS.BN13 rats, or other normotensive rat strains e.g., Sprague-Dawley rats, that have been extensively characterized in studies by our laboratory and others. Aim 2 will utilize pharmacological tools, endothelial removal, and measurement of key biochemical mediators of vascular relaxation in order to determine the mechanisms that mediate vascular relaxation in response to vasodilator stimuli in isolated middle cerebral arteries of SS.BN13 consomic rats on a low salt diet, and to identify vascular relaxation mechanisms that are impaired in vessels of SS/Mcw rats on low salt diet. Aim 3 will utilize i.v. infusions of the ANGII receptor antagonists losartan (ATI) and PD123319 (AT2) to determine the role of specific ANGII receptor subtypes in maintaining vascular relaxation mechanisms in the middle cerebral artery under normal physiological conditions in SS.BN13 rats and in renin congenic rats, and to assess the role of specific ANGII receptor subtypes in mediating any protective effect of low dose ANGII infusion to restore normal responses of the middle cerebral artery to vasodilator stimuli in

SS/Mcw rats on a low salt diet. The demonstration that ANGII may have a permissive role in maintaining vascular relaxation mechanisms in normotensive animals is a completely new aspect of ANGII's complex physiological role that has only recently been described and is largely unexplored. In this respect, the studies proposed in this project address a conceptually innovative aspect of the physiological role of ANGII in regulating vascular function. When completed, these studies will not only enhance our understanding of the role of ANGII and its receptors in regulating vascular reactivity under normal physiological conditions, but will also provide insight into the mechanisms of the impaired reactivity of resistance vessels to vasodilator stimuli in SS/Mcw rats, a genetic model of salt sensitive hypertension that has many similarities to the salt sensitive forms of hypertension that develop in humans, particularly in AfricanAmericans.

Project Title: ANGIOTENSIN II AND DIABETIC RETINOPATHY Principal Investigator & Institution: Scicli, Alfonso G.; Senior Staff Research Investigator; Molecular Biology; Case Western Reserve Univ-Henry Ford Hsc Research Administraion Cfp-046 Detroit, Mi 48202 Timing: Fiscal Year 2003; Project Start 01-JAN-2003; Project End 30-NOV-2006 Summary: (provided by applicant): Clinical trials suggest that Angiotensin Converting Enzyme inhibitors (ACEi) slow the progression of diabetic retinopathy. However, there is little experimental evidence that Angiotensin II (Ang II) is a critical pathogenetic factor in the development of diabetic retinopathy. ACEi's act systemically decreasing blood pressure (BP) and may also act by decreasing local Ang II effects or by non-Angdependent mechanisms. Vascular Endothelial Growth Factor (VEGF) is responsible for retinal neovascularization and stimulates expression of Intercellular Adhesion Molecule-1 (ICAM-1), causing leukostasis, capillary plugging and vasopermeability. Reactive oxygen species (ROS) may mediate in part Ang II effects. We have found that Ang II is angiogenic, and that this effect is supressed by SU5416, a highly selective inhibitorof VEGF receptor (VEGF R) responses, suggesting that Ang II can act via VEGF R. In addition, intravitreal Ang II induces retinal leukostasis in vivo. We hypothesize that: a) inhibitionof Ang II ameliorates diabetic retinopathy by mechanisms independent of BP reduction and b) Ang II acts via ROS and VEGF R to increase the expression of retinal leukocyte adhesion molecules, leukostasis, capillary plugging and vasopermeability. Our specific aims are: Aim 1: To compare the effects of chronic treatment with a Ca- Channel blocker, (nifedipine), an ACEi (ramipril), and a AT1 receptor antagonist (Iosartan), on diabetic retinopathy in streptozotocin-induced diabetes (SZD), a rat model of type 1 diabetes (12 months treatment), and in a novel model of retinal neovascularization, the Koletsky rat, a hypertensive model of type 2 diabetes, (10 months treatment). All treatments may lower BP but nifedipine does not inhibit the renin angiotensin system (RAS). We expect that retinopathy is decreased by ramipril and perhaps Iosartan but not nifedipine. Aim 2: To determine whether retinal leukostasis, capillary plugging, vasopermeability and adhesion molecules: a) decrease after treatment with either an ACEi or an Ang II ATl inhibitor in SZD rats (1-2 weeks), and in normal rats 48 hrs after ivt VEGF, and b) increase after ivt Ang II, and whether anti-oxidants or SU5416 inhibit these responses. In Aim 3 we will study in retinal endothelial cells in vitro if Ang II increases adhesion molecules and leukocyte adhesion via ROS and VEGF R and the role of NF-kB. These studies will help understand the role of the RAS in diabetic retinopathy. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: ANGIOTENSIN II BLOCKADE Principal Investigator & Institution: Ibrahim, Hassan N.; Medicine; University of Minnesota Twin Cities 200 Oak Street Se Minneapolis, Mn 554552070 Timing: Fiscal Year 2002; Project Start 05-SEP-2002; Project End 30-JUN-2007 Summary: (provided by applicant): Renal transplant loss due to chronic allograft nephropathy (CAN) is widely acknowledged as a major problem that has increased in relative importance as the incidence of early graft loss from acute rejection has declined. Studies from various centers, including the University of Minnesota, suggest that, after excluding patients dying with a functioning graft, as many as 80% of patients who will return to dialysis do so because of CAN. At the present time there are no therapeutic options once the clinical manifestations of CAN have developed. Testing measures to prevent CAN have not been addressed. The overall purpose of this project is to investigate the role of the renin-angiotensin-aldosterone system (RAAS) in the development of CAN. This system plays an important role in the progression of many experimental and clinical renal diseases. Furthermore, blockade of this system with angiotensin converting enzyme inhibitors and angiotensin II receptor blockers has yielded beneficial results in retarding injury and progression in numerous intrinsic renal diseases. This study specifically investigates the long term benefit of the angiotensin II receptor blocker, Iosartan, in the prevention of cortical interstitial volume expansion (an accurate predictor of long term graft function) and graft loss from biopsy proven CAN in a 5 year, randomized, double masked, placebo controlled study of kidney transplant recipients. This clinical trial will directly test the hypothesis that blockade of the renin angiotensin aldosterone system will provide a substantial benefit through blood pressure lowering independent mechanisms, namely, interruption of tibrogenic pathways, anti-proteinuric actions, amelioration of hyperfiltration and possibly some immunomodulatory effects. The proposed studies will also characterize the interstitial ultrastructural compositional changes that occur in the renal allografts with CAN, the effects of treatment on these changes and provide a complete description of the incidence and predictors for the development of transplant glomerulopathy. These studies will also determine the impact of angiotensin II receptor blockade on the rate of decline of glomerular filtration rate, as well as the impact of glomerular size on the rate of graft loss from CAN, the incidence and the progression of post transplant proteinuria, the nature of the permselectivity defects responsible for the proteinuria and will also explore the association of proteinuna with graft loss from CAN. This trial will also help construct a profile for the RAAS in the transplant recipients and explore the relationship between two genes polymorphisms, ACE and TGF-b and CAN. These studies should help to describe the natural history, nature and pathogenesis of CAN, elucidate early markers and predictors of this important disorder and, perhaps, define a safe and useful preventative strategy.

Project Title: ANGIOTENSIN II, OXIDATIVE STRESS, AND ATHEROSCLEROSIS Principal Investigator & Institution: Cohen, Richard A.; Associate Professor; Boston Medical Center Gambro Bldg, 2Nd Fl, 660 Harrison Ave, Ste a Boston, Ma 02118 Timing: Fiscal Year 2002; Project Start 01-SEP-1997; Project End 31-AUG-2005 Summary: (Adapted from the Investigator's Abstract): Oxidative stress is thought to participate in vascular dysfunction and remodeling that accompanies angiotensin II (AII)-induced hypertension, but the source and cellular sources of oxidant species and their precise role is poorly understood. Recent studies in the laboratories of the two PI's
Studies

have elucidated a novel role for the aortic adventitia as the site of elaboration of both superoxide anion (O2-) and nitric oxide (NO) radicals, indicating that the adventitia is a major site of oxidative stress. New studies indicate that the increased elaboration of O2by AII is indicated by prominent nitrotyrosine staining of the adventitia, likely as a result of production of the reaction product of O2- and NO, peroxynitrite (OONO-). There are many sources of O2- in the vascular wall, but recent studies indicate that multiple subunits of the neutrophil NAD(P)H oxidase are present in the adventitia where O2- is greatest. Preliminary studies in which AII was infused into mice that are deficient in one NADPH oxidase subunit, gp91phox, show a blunted aortic O2-, hypertrophic, and proliferative response to AII compared with wild type mice, despite a similar hypertensive response. Proposed studies in rats and mice will elucidate the hypothesis that oxidative stress mediated by adventitial NAD(P)H oxidase-derived O2participates in the myogenic, hypertrophic, and proliferative vascular response in AIIinduced hypertension. The proposed studies will also take advantage of preliminary work on Apo E deficient mice (EKO) to determine the significance of AII-induced oxidative stress in atherosclerosis. Preliminary studies in these mice indicate that captopril and losartan reduce atherosclerosis (suggesting a role for AII), and that hypothetically under the influence of AII, there is increased production of O2- and OONO-, as indicated in preliminary studies by nitrotyrosine.

Project Title: AT2 MEDIATED ANGIOTENSIN II SIGNALING Principal Investigator & Institution: Mauch, Teri J.; Associate Professor; Pediatrics; University of Utah Salt Lake City, Ut 84102 Timing: Fiscal Year 2003; Project Start 01-JUN-2003; Project End 30-APR-2005 Summary: (provided by applicant): Fetuses deprived of the vasoactive peptide and potent growth factor Angiotensin II (Ang II) are born with renal dysplasia, and they require dialysis and transplantation for long term survival. Ang II binds at least two receptors, AT1, and AT2. AT1 mediates cell growth and division, vasoconstriction, and salt retention. Decreased AT1 activation likely mediates some of the fetotoxicity in Ang U -deprived babies. AT2, however, is the predominant Ang II receptor in the fetal kidney, and its expression declines at birth. In mediating cell death, vasodilation, and salt excretion, AT2 seems to oppose AT1 action, but its downstream signaling pathways have yet to be identified, and its role in fetal nephrogenesis has not been delineated. In preliminary studies using cultured rat metanephroi, isolated from confounding variables, we found that a) Ang II stimulated ureteric bud (UB) branching, b) AT1 blockade decreased UB branching, whereas c) AT2 antagonism increased UB branching. Normal nephrogenesis involves tightly controlled reciprocal interactions between the metanephric mesenchyme and the invading UB. Excessive UB branching results in abnormal and ectopic induction of mesenchyme, whereas insufficient UB branching causes renal hypoplasia. We hypothesize that AT2 activation inhibits UB branching, and we seek to identify changes in downstream gene expression associated with this process.Specific Aim 1: To further test the hypothesis that AT2 inhibits UB branching in cultured fetal rat kidneys. a. Using confocal microscopy and lectin staining we will examine UB branching under conditions that specifically activate or antagonize AT2.b. We will optimize culture conditions that maximally activate or suppress AT2 signaling

for subsequent subtraction cloning studies.Specific Aim 2: To identify which genes are differentially expressed following AT2 activation or suppression.a. Subtraction cloning will be performed between kidneys at 2 time points following AT2 activation or antagonismb. Hybridization analysis will be used to confirm differentially expressed clones.c. Differentially expressed cDNAs will be sequenced to identify candidate genes. NCBI BLAST searches and bioinformatics will be used to sort differentially expressed genes into structural and functional categories.d. Quantitative RT-PCR will confirm the magnitude of change of selected clones.e. The spatial expression of differentially expressed clones will be assessed using in situ hybridization.The ability of candidate genes identified by this screen to influence ureteric bud branching will be tested in future studies.

Project Title: BRAINSTEM NEURONS IN NEUROGENIC HYPERTENSION Principal Investigator & Institution: Sved, Judith C.; Neurology; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2004; Project Start 01-FEB-2004; Project End 31-JAN-2006 Summary: (provided by applicant): The overall objective of this proposal is to evaluate a central neural mechanism involved in the long term regulation of cardiovascular function that may ultimately be involved in the pathogenesis of certain forms of hypertension. Selective disruption of central nervous system function can produce acute as well as chronic elevations in arterial blood pressure (AP) and influence cardiovascular reflexes. The rostra ventral lateral medulla (RVLM) is important for the maintenance of baseline AP and its reflexive regulation and is comprised of two neurochemically distinct neuronal cell populations, the C1 cell population that contains the enzyme phenylethanolamine-N-transferase (PNMT) and those cells that do not contain PNMT. Recently a technique has been developed to selectively destroy the C1 cell population in rats that has allowed the evaluation of the role of these neurons in cardiovascular regulation. The proposed studies will examine the effect of C1 RVLM lesions in two strains of genetically hypertensive rats (spontaneously hypertensive rats, SHR and Dahl salt-sensitive rats, DS) using radio telemetry to monitor AP and heart rate in freely moving rats prior to and during an extended time course following destruction of C1 neurons. Responses to stressful stimuli and anti-hypertensive drugs will also be tested. These experiments will test the hypothesis that C1-RVLM neurons are important for the maintenance of hypertension in these two models, extending acute studies in anesthetized rats suggesting that the RVLM is important in these forms of hypertension and further our understanding of how the central nervous system is involved in the pathogenesis of hypertension.

Project Title: CARDIAC SYMPATHETIC AFFERENT RELEX IN HEART FAILURE Principal Investigator & Institution: Wang, Wei; University of Nebraska Medical Center Omaha, Ne 681987835 Timing: Fiscal Year 2002 Summary: Heart failure (HF) is characterized by an elevation in sympathetic tone. The mechanisms responsible for the sympatho-excitation of HF are not completely understood. Recent studies from this laboratory have shown that the cardiac "sympathetic afferent" reflex is enhanced in dogs with pacing-induced HF. The mechanisms by which this enhancement occurs are unclear. There is an enhancement in

afferent fiber sensitivity to bradykinin and capsaicin. Preliminary evidence from this laboratory suggests that an enhanced central gain of this reflex is, in addition, responsible for the augmentation of this reflex. Furthermore, we have shown that central angiotensin II (Ang II) is at least one mediator for this enhancement. A second mechanism which may explain the increased gain of he cardiac sympathetic afferent reflex in HF is a decrease in nitric oxide (NO) production in several central sites which regulate sympathetic outflow. We hypothesize that both an increase in central Ang II and a decrease in central NO contributes to the increase in the sensitivity of the cardiac sympathetic afferent reflex and to the tonic sympatho-excitatory state in dogs with HF. Therefore, the specific aims of this project are to: 1) determine if the central gain of the cardiac sympathetic afferent reflex in dogs with HF is related to increased levels of central Ang II or to changes in Ang II type1 receptor density or both, 2) determine if acute and chronic central administration of the Ang II receptor antagonist, losartan and L-158,809 and/or NO donors prevent or reduce the enhancement of the cardiac sympathetic afferent reflex in dogs with HF, 3) determine if bradykinin prostaglandins and NO are mediators of the enhanced sensitivity of cardiac sympathetic sensory endings in dogs with HF, and 4) determine if chronic thoracic sympathetic deafferentation alters the time course and/or magnitude of the sympatho-excitatory response during the development of pacing-induced HF. These studies integrate into the overall scope of this Program Project in that the regulation of sympathetic outflow in HF is likely to be mediated by a variety of peripheral inputs with important modulation from central substances. The cardiac sympathetic understanding of neuro-humoral regulation in this disease state should include this potentially potent reflex.

disease following obstruction of the urinary tract. The principal investigator hypothesizes that within hours of ureteral obstruction there is increased expression of the renin angiotensin system within the renal cortical proximal tubules. The increased epithelial production of angiotensin II stimulates the angiotensin II type I receptor and this increases the proximal tubule production of osteopontin. This is a potent chemoattractant for macrophages and this leads to the infiltration of macrophages and such macrophage-dependent mechanisms of inflammation and injury as is dependent on TGFbeta1. There are three specific aims: The first specific aim will investigate the critical role of increased osteopontin expression after urinary tract obstruction via its capacity to attract macrophages to increase cortical TGFbeta1 expression. This specific aim will utilize an osteopontin knockout mouse in which the effects of obstruction in this knockout model will be examined from the standpoint of evolution of interstitial disease assessed histologically, and by immunohistochemistry and by in situ hybridization. These studies would be complemented by in vitro studies in which primary cultures of proximal tubular suspensions from osteopontin knockout and wildtype mice will be studied for their ability to induce attraction of macrophages. The second specific aim is to determine proximal tubular angiotensinogen, angiotensinconverting enzyme, and angiotensin II type 1 receptor mRNA and protein, and ACE activity during the initial as well as during the sequential time points for up to 168 hours post-ligation. The third specific aim will mechanistically determine the roles for ACE and angiotensin II type 1 receptor activation in the expression and macrophage attraction, effects of osteopontin using an in vivo rat model of experimental hydronephrosis, and an osteopontin knockout mouse model. In these studies the renin angiotensin system will be manipulated with the use of an ACE inhibitor, enalapril, and an AT-1 blocker, losartan.

Project Title: DETERMINANTS OF MAXIMAL O2 TRANSPORT Principal Investigator & Institution: Wagner, Peter D.; Professor of Medicine & Bioengineering; University of California San Diego 9500 Gilman Dr, Dept. 0934 La Jolla, Ca 920930934 Timing: Fiscal Year 2002 Summary: Chronic diseases (COPD, heart failure, renal failure) are marked by reduced exercise capacity. There is increasing evidence that skeletal muscle structure and function may be intrinsically abnormal in such conditions. The present proposal continues work from the current cycle to better understand the mechanisms of exercise limitation in both health and disease, in particular the role of skeletal muscle. Physiological approaches already developed under the PPG involving muscle O2 transport analysis (large versus small muscle mass exercise, femoral blood flow, blood gas sampling, magnetic resonance spectroscopy to measure intracellular P02, morphology to assess diffusion distances and capillary surface area) will be combined with molecular-level studies focused on genes associated with muscle angiogenic responses to exercise, since the amount of capillary surface appears critical to O2 transport limitation. This integrated approach will be applied in both animal and human studies, the latter in both health and chronic disease (heart failure, chronic obstructive pulmonary disease). Animal work will use mechanistic interventions not possible in man to complement human experiments, and in both, the molecular approaches will be applied in intact physiological systems. Major goals include: 1) separating O2 transportbased exercise limitation from that due to intrinsic muscle abnormalities in chronic diseases; 2) determining if VEGF is essential to angiogenesis using Cre/loxP targeted

knockout strategy, as well as VEGF antagonists such as Suramin, Losartan and Captopril; 3) defining the mechanisms that normally increase VEGF message and protein capillarity in chronic diseases. Our ultimate objective is to identify abnormalities of muscle O2 transport in chronic disease at the level of gene regulation, in the hope of eventual gene-targeted therapy. We hypothesize that these will centrally involve the muscle angiogenic response to exercise. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: EARLY NEPHROPATHY IN NIDDM Principal Investigator & Institution: Myers, Bryan D.; Professor; Medicine; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2002; Project Start 01-SEP-1999; Project End 31-AUG-2004 Summary: We propose to use novel methods to characterize the evolution of early diabetic glomerular injury (DGI) in 70 Pima Indians with NIDDM and microalbuminuria. They will be entered into a randomized, controlled trial of losartan vs placebo lasting 60-84 months. GFR, its hemodynamic determinants and albuminuria, will be monitored annually. More elaborate physiological studies, an analysis of glomeruli obtained by biopsy and mathematical modelling of filtration properties of glomeruli will be performed after 60 months. We wish to test the following four hypotheses. The first hypothesis is that evolution from micro- to macroalbuminuria is a consequence of impairment of a size-selective filtration barrier. We propose to compute the effective radii of functional pores from sieving coefficients of polydisperse ficoll, a rigid and spherical polymer of sucrose that replicates the molecular configuration of proteins. Confocal immunomicroscopy of podocytes will seek a structural basis for protein-permeable pores. The second hypothesis is that podocyte injury and deformation lowers glomerular hydraulic permeability (k) and is the principal determinant of a decline in GFR from elevated to normal levels as DGI becomes overt (macroalbuminuria). Morphometric analysis of glomeruli will examine podocyte density and foot process, slit diaphragm, GBM, and endothelial fenestral dimensions. A novel hydrodynamic model of viscous flow will be used to compute k from these quantities, and single nephron Kf from k and filtration surface area(s). The third hypothesis is that podocyte injury is a consequence of specific changes in epithelial cellcell and cell-substrate interactions. We will accordingly use confocal immunomicroscopy to examine for alterations in the distribution of adhesion and tight junction molecules in the podocyte cell membrane and slit diaphragm. The fourth hypothesis is that blockade of the renin-angiotensin system will confer renoprotection by conserving podocyte function and structure, as judged by less impairment of barrier function and computed k in losartan than placebo-treated individuals. Because GFR remains constant for up to 5 years after detection of microalbuminuria, it is our hope that structural determinants of computed k and SNKf will provide alternative outcome measures for demonstrating effective renoprotection by angiotensin blockade early in the course of DGI.

Summary: Over 60 million Americans use herbal medicines, of whom one fourth also take prescription drugs. Physicians often are unaware of herbal use and of possible drug/herb interactions. Ginseng and ginkgo, enhancers of physical and mental performance, are two of the most widely taken herbals. We propose a double- blind, randomized, prospective study of effects of ginseng and ginkgo on 1) disposition of probe drugs, 2) cognitive function, and 3) glutathione-S-transferase (GST) and quinone reductase (NQO1), enzymes implicated in chemoprevention of cancer. Probe drugs will be administered to study effects of herbs on their disposition, not for therapeutic effect. Ideal probes must be safe, well tolerated, have minimal pharmacological effect, and share known metabolic pathways with other clinically used drugs. Medically stable drug-free non-smokers will be enrolled. During a 4-week single-blind run-in subjects will be given a 4-drug probe cocktail: caffeine to study cytochrome P4501A2 (CYP1A2), dextromethorphan for CYP2D6, buspirone (and endogenous cortisol) for CYP3A and fexofenadine for P-glycoprotein. Losartan will be given separately for CYP2C9. These enzymes metabolize over 95 percent of clinically used drugs. Enzyme activities will be determined by assaying appropriate blood and urine specimens for probe drugs and metabolites. Cognitive function will be tested and blood lymphocytes collected for measuring GST and NQO1 activities. Sixty subjects will then be randomly assigned to one of 4 double-blind treatment groups of 15 each: 1) ginseng extract (Ginsana), 2) ginkgo extract (EGb761), 3) both herbs, or 4) matching placebos. Tolerability of herbs will be determined. After 6 to 8 weeks of twice daily treatment with study agents, all effect parameters will be reevaluated: probe drug pharmacokinetics, cognitive function, and GST and NQO1 in blood lymphocytes. Interactions of chronic ginseng and ginkgo with drug-metabolizing pathways and with cognitive function will thus be determined. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: IMPROVING OUTCOMES IN DIABETIC NEPHROPATHY Principal Investigator & Institution: Toto, Robert D.; Professor of Internal Medicine; Internal Medicine; University of Texas Sw Med Ctr/Dallas Dallas, Tx 753909105 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2004 Summary: (provided by applicant): The long-range objective of this project is to prevent progression of diabetic nephropathy, the leading cause of end-stage renal disease (ESRD). In most patients diabetic nephropathy progresses inexorably to ESRD despite inhibition of the renin-angiotensin-aldosterone system with angiotensin converting enzyme inhibitors (ACEIs) or angiotensin II type 1 receptor blockers (ARBs). The specific aims of this proposal are to: 1) recruit a multi ethnic cohort of 72 young adults (ages 20-40) with type 1 (n=36) or type 2 (n=36) diabetes and overt nephropathy (defined as a urine albumin/creatinine ratio > 300 mg albumin/g creatinine) and randomize in a double blind fashion to a control group consisting of ACEI-based therapy alone (ramipril 40 mg once daily) or one of two experimental groups: a) ACEI + ARB (ramipril 40 mg once daily plus Iosartan100 mg once daily) or b) ACEI + mineralocorticoid receptor antagonist (MRA) (ramipril40 mg once daily plus spironolactone 25 mg once daily); 2) conduct a 12-month prospective study to determine if proteinuria is reduced to a greater extent when either the ARB or MRA is added to ACEi-based therapy. This study is powered to detect a 40% greater reduction in 24-hour urine albumin/creatinine ratio in either experimental group versus control (alpha= 0.05, beta=0.20, repeated measures analysis of variance). Secondary endpoints to be examined include:(a) serum potassium and creatinine to assess safety, (b) TGF-beta, as a surrogate marker for ongoing renal injury, (c) plasma renin activity, angiotensin II and aldosterone levels and (d) plasma lipids and lipoprotein composition; and 3) perform repeated ambulatory blood pressure monitoring (ABPM) to examine the renoprotective effect of the 3 different regimens at comparable 24-hour BP of < 125/75 mmHg. The deliverables include: 1) documentation of the safety of maximal dose combination therapy; 2) the feasibility of utilizing 24-hr ABPM to establish BP independent renoprotective effects of specific antihypertensive therapies; and 3) provide preliminary data for future largescale studies to test efficacy and safety of combining ACEi with MIRA therapy on renal outcomes.

Project Title: MAXIMIZE RAS BLOCKADE IN DIABETIC NEPHROPATHY Principal Investigator & Institution: Meyer, Timothy W.; Professor of Medicine; Medicine; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2004 Summary: (provided by applicant): Blockade of the renin-angiotensin system (RAS) by inhibition of angiotensin converting enzyme (ACE) reduces proteinuria and slows loss of renal function in patients with diabetic nephropathy. But the optimal manner in which ACE inhibitors should be used to limit renal injury has been remarkably little studied. In particular, further studies are needed to identify treatments which should be combined with ACE inhibition to maximize the benefit of RAS blockade. The proposed studies will assess the value of two such treatments. The first aim will be to determine whether angiotensin receptor blockade increases the antiproteinuric effect of ACE inhibition is patients with diabetic nephropathy. The putative beneficial effect of adding angiotensin receptor blockade to ACE inhibition has been widely advertised but not adequately tested. Studies conducted to date have shown only that adding an angiotensin receptor blocker (ARB) reduces proteinuria in patients maintained on relatively low doses of an ACE inhibitor. The proposed study will assess the effect of adding an ARB to higher doses of an ACE inhibitor. These studies will reveal whether ARB addition has any effect that cannot be obtained more simply and more cheaply by ACE inhibition alone. The second aim will be to determine whether diuretic use

increases the antiproteinuric effect of ACE inhibition in patients with diabetic nephropathy. Previous studies have shown that addition of a diuretic lowers proteinuria in patients with non-diabetic renal disease who are maintained on ACE inhibitors. This finding suggests that ACE inhibition reduces proteinuria most effectively when ECF volume is low. The proposed studies will establish where addition of a diuretic to an ACE inhibitor has the same beneficial effect in patients with diabetic nephropathy. Ultimately, the ability of improved RAS blocking regimens to slow the progression of diabetic nephropathy can only be established by large, long term trials. But the number of such trials which can be performed is limited. Short term trials, such as those described in this proposal, are urgently required to help identify treatment regimens which merit further, longer term study.

Project Title: MECHANISMS FOR CARDIOVASCULAR CONTROL EARLY IN DIABETES Principal Investigator & Institution: Brands, Michael W.; Professor; Physiology and Endocrinology; Medical College of Georgia 1120 15Th St Augusta, Ga 30912 Timing: Fiscal Year 2003; Project Start 01-JAN-1997; Project End 31-MAR-2007 Summary: (provided by applicant): We have shown that hyperglycemia at the onset of Type I diabetes causes significant hypertension if it is induced in rats with chronic blockade of nitric oxide synthesis. The hypertension is prevented by blocking angiotensin II, or the sympathetic nervous system; but our data suggest the two systems are linked in this response and may involve superoxide and thromboxane. Blood pressure and nitric oxide also track closely with GFR. The studies in this proposal will test the central hypothesis that nitric oxide protects against hypertension at the onset of diabetes by counteracting pressor actions of the sympathetic and renin-angiotensin systems. The Specific Aims are: 1) to test the hypothesis that nitric oxide protects against AngII-induced hypertension at the onset of diabetes by: a) chronically clamping (fixing) renin-angiotensin system activity at normal levels;b) blocking AngII action in rats with chronic intravenous and intrarenal i) ramipril and ii) iosartan; c) blocking AngII action in mice with ACE gene knockout; d) determining if gradual onset of diabetes causes the same renin secretion and blood pressure responses; e) determining whether low sodium intake increases the dependence of blood pressure on nitric oxide. 2) to test the hypothesis that the SNS contributes to the hypertensive response primarily through renal mechanisms. We will: a) determine the roles of a versus b receptors in mediating the renal, renin, and blood pressure responses:b) remove the renal nerves to test the role of the kidney in mediating the sympathetic pressor effect; c) determine if a decrease in ANG II is required for adrenergic blockade to prevent the hypertension; d) determine if the SNS effect is due to increases in SNS activity, or whether it plays a permissive role, 3) to test the hypothesis that nitric oxide counteracts AngII-dependent superoxide and thromboxane production to control blood pressure at the onset of diabetes. We will determine this by: a) "blocking" superoxide with a superoxide dismutase mimetic in rats and gene overexpression in mice; b) quantifying the degree to which AngII determines whether superoxide significantly affects blood pressure: c) determining if thromboxane receptor blockade will decrease blood pressure if superoxide is not increased: d) determining whether knockout of superoxide dismutase 1 exacerbates the hypertensive response.

FAMILIAL
HYPERTROPHIC
Principal Investigator & Institution: Marian, Ali J.; Associate Professor of Medicine; Medicine; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 31-JUL-2006 Summary: (provided by applicant): The objective is to identify modifier genes that affect hypertrophy in human familial hypertrophic cardiomyopathy (FHCM) and determine whether pharmacological inhibition of their effects can induce regression of established hypertrophy in a transgenic rabbit model of human FHCM. FHCM, an autosomal dominant disorder occurring 1 in 500, is the most common cause of sudden cardiac death (SCD) in the young. In the elderly, occurring 9 in 500, it is a major cause of mortality and morbidity. Ten genes and >100 mutations were identified with the majority due to 3 genes. Reasons to search selectively for modifier genes of hypertrophy are: hypertrophy is the main determinant of mortality and morbidity in FHCM; it is required for the diagnosis; it is an independent risk factor for SCD and failure due to FHCM and other causes; can be quantified non-invasively and hypertrophy whether due to FHCM or other causes, is known to be modified genetically. Hypertrophy due to any cause is always associated with fibrosis, a putative substrate for SCD. Genotypephenotype correlation studies indicate marked variation in age of onset and severity of hypertrophy even within the same family with the same mutation. The variation is due in large part to modifier genes and is suggested by association studies (e.g. ACE gene) but a systematic genomic search is necessary. This requires a repository of families with FHCM, a mathematical model and ideally an established genetic animal model of FHCM to confirm the predicted biological effect of modifier genes. Recent application of the Monte Carlo Markov Chain Methods (MCMC) in multiple families with Alzheimer's was shown to be highly sensitive in detecting modifier genes. Thus, utilizing 50 previously well-characterized families with FHCM from a computerized database, the genome will be screened initially with 400 DNA markers and analyzed by the MCMC methods to identify regions with modifier genes (Aim 1) followed by additional closely spaced markers in these regions to identify candidate genes (Aim 2). Independently, 350 unrelated probands with FHCM will be analyzed to determine if an association exists between hypertrophy and SNPS identified in candidate modifier genes (Aim 3). An established rabbit model with a phenotype identical to human FHCM will be utilized to determine the biological effect of identified candidate modifier genes. The ACE gene, previously implicated as a modifier of hypertrophy, is the initial candidate. It's effect will be inhibited with Losartan, a renin- angiotensin system (RAS) blocker, in the rabbit model to determine if there is regression of hypertrophy. Similarly, as other modifiers are identified they will be tested in the rabbit model. Identification of modifiers is necessary to assess prognosis and develop more comprehensive treatment. Treatment found to induce regression of hypertrophy in the rabbit with FHCM will most likely also induce regression of hypertrophy in human FHCM and hypertrophy due to other cardiac causes.

Summary: (provided by applicant): Our broad, long-term objective is to understand the structural basis of the functions of receptors for angiotensin II (Ang II). The type 1 (AT1) receptor mediates diverse intracellular responses to Ang II in the regulation of blood pressure, hydromineral balance, cardiac hypertrophy and cell proliferation. The AT1 receptor is a novel paradigm for study since it is a G protein-coupled receptor with the unique ability to directly activate, besides G proteins, tyrosine kinases. Our structurefunction analysis has identified critical interactions of the AT1 receptor with the agonist Ang II and the competitive antagonist losartan. These studies have yielded valuable mutants with loss of specific function and ligand-independent activation. Interpretation of structural consequences of these mutations by using a molecular model provides important insight into the mechanism of activation, desensitization, internalization and differential tyrosine kinase activation by the AT1 receptor. A novel class of dominantnegative (dn) AT1 receptor mutants have indicated that oligomerization of AT1 receptor may be essential for some functions. A combination of site-directed mutagenesis, sitedirected chemical modification, molecular pharmacology, cell signaling and molecular modeling studies will be used to investigate some novel aspects of AT1 receptor structure-function. The specific aims for this competing renewal are: (1) To validate the novel structural features predicted by the homology model of the AT1 receptor based on the crystal structure of rhodopsin; (2) To elucidate the structural basis of prolonged inhibition of the AT1 receptor by insurmountable antagonists which are therapeutically better than competitive antagonists; and (3) To dissect the molecular basis of dominantnegative AT1 receptor mutants. Specific Aims 1 and 2 will use the experimental strategy employed in our previous studies. In addition, we will use site-directed cystein modification studies to obtain structural information. The dnmutants will be tested for non-productive G-protein interaction and oligomerization using coimmunoprecipitation and fluorescence resonance energy transfer studies. The dnmutant effects on Ang Il-specific cellular function and proteome responses will be evaluated. Validation of the model is critical for identification of structural constraints regulating the functions of the AT1 receptor. A refined molecular model will allow future improvement of antagonists. A better understanding of the mechanism of insurmountable antagonism will provide insight into design of novel anti-hypertensive, cardio- and reno-protective drugs that harbor greater therapeutic benefits. The study of trans-dominant effects will lead to novel mechanisms of signal transduction through oligomerization. The dn-mutants may serve as important tools for discovering cross regulation of intracellular signal-transduction pathways that are relevant to pathophysiology.

Project Title: MULTICENTER TRIAL OF FOCAL GLOMERULOSCLEROSIS Principal Investigator & Institution: Gipson, Debbie S.; Medicine; University of North Carolina Chapel Hill Aob 104 Airport Drive Cb#1350 Chapel Hill, Nc 27599 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): Idiopathic focal segmental glomerulosclerosis (FSGS) is a progressive scarring disorder that causes proteinuria and kidney failure in the majority of affected individuals. There is considerable controversy regarding the best therapeutic intervention and the definition of pathological variants of FSGS that may impact therapeutic response rates. This proposal focuses on the design and conduct of a collaborative multicenter trial that will evaluate response rates of children and young adults with the nephrotic syndrome due to FSGS treated with cyclosporin A as compared to corticosteroids plus angiotensin receptor blocker therapy. It will utilize a

newly determined FSGS classification scheme as defined by the NY Pathology Consensus Group that includes one of our collaborators. In addition, since incidence of idiopathic FSGS has been increasing over the past 2 decades, a case-control study that will evaluate risk factors for FSGS is proposed to run concurrently with the trial. Our proposed southeastern clinical coordinating center will provide strength to the planned nation-wide trial through our large patient population with FSGS, the strength of the UNC nephropathology service, and the investigators' long track record of clinical trial and epidemiologic research in glomerular diseases through the UNC-Chapel Hill based Glomerular Disease Collaborative Network. In conjunction with committed collaborating sites, our group has over 400 FSGS patients who would be eligible for the proposed trial, as well as established mechanisms for including prospectively identified patients. The proposed case-control study will evaluate risk factors for the development of FSGS such as body mass, birth weight, viral illnesses and smoking in all patients screened for entry into the trial.

Project Title: NO AND THE MAGNOCELLULAR NEUROENDOCRINE SYSTEM Principal Investigator & Institution: Kadekaro-Kutyna, Massako; Professor; Surgery; University of Texas Medical Br Galveston 301 University Blvd Galveston, Tx 77555 Timing: Fiscal Year 2002; Project Start 01-APR-2000; Project End 31-MAR-2004 Summary: (Adapted from the Investigator's Abstract) The investigators have shown previously that nitric oxide (NO), a lipophilic gas synthesized by NO synthase (NOS) from L-arginine, has important functions in neuroendocrine and behavioral osmoregulation, as well as blood pressure control. The experiments proposed in this application will clarify the site and mechanisms by which NO modulates the magnocellular neuroendocrine system. Since NO is synthesized in magnocellular neurons and cells in the supraoptic nuclei (SON) project almost exclusively to the posterior lobe of the pituitary gland to regulate neuroendocrine responses to fluid and electrolyte imbalances our studies will focus on the SON. The studies are designed to test two hypotheses: 1) NO synthesized locally in the SON during osmotic stimulation activates guanylyl cyclase to increase 3',5' cyclic guanosine monophosphate (cGMP) which results in 2) inhibition of angiotensin II and prostaglandin release in the SON to attenuate peripheral secretion of oxytocin. The specific aims are to determine: 1a) whether the activities of NOS (i.e. citrulline) and guanylyl cyclase (i.e. cGMP) increase in microdialysates of the SON during osmotic stimulation; 1b) whether inhibiting the production of NO with L-Name retrodialyzed in both SON prevents the increase of cGMP in microdialysates associated with increasing plasma levels of oxytocin during osmotic stimulation; 1c) whether retrodialyzing both SON with 1H-[1,2,4) oxodiazolo [4,3-a)quinoxalin-1-one (ODQ), a specific inhibitor of soluble guanylyl cyclase, decreases intranuclear production of cGMP and reproduces the effects of L-Name on plasma secretion of oxytocin during osmotic stimulation. 2a) whether ANG II and prostaglandin levels increase locally in the SON following retrodialysis with L-NAME during osmotic stimulation; 2b1) whether this neuroendocrine response to L-NAME can be prevented by losartan, an ANG II AT1 subtype receptor antagonist, or 2b2) indomethacin, an inhibitor of cyclooxygenase, the enzyme that converts arachidonic acid to prostaglandins. This research is important because it will further our understanding of the neurobiology of body fluid regulation by NO. Since NO is required for plasticity of neural systems involved in learning and memory, as well as participates in neurotoxicity, clarifying the mechanisms of action of this novel neurotransmitter may

Principal Investigator & Institution: Dunlap, Norma K.; Chemistry; Middle Tennessee State University Murfreesboro, Tn 37132 Timing: Fiscal Year 2003; Project Start 01-JUN-2003; Project End 31-MAY-2006 Summary: (provided by applicant): Although there are currently numerous antibacterial drugs on the market, many bacteria are becoming resistant to existing drugs, and the emergence of these drug-resistant microorganisms is a significant threat to public health. Virtually all classes of antibacterials in use have been circumvented to some extent by various resistance mechanisms and as a result there is a continual need for new structural classes of antibacterials. Penicillins are bacterial cell wall synthesis inhibitors and act by inhibition of Penicillin Binding Proteins (PBP's), also know as D-Dpeptidases. The substrate for the D-D-peptidases is the cell wall peptidoglycan strand ending in D-alanine-D-alanine. However, penicillins and other drugs of that class were not designed to inhibit the D-D-peptidases. The objective of this application is to design and synthesize inhibitors of the D-D-peptidases as potential antibacterial drugs. Hydroxyethylene peptidomimetics of peptidic enzyme substrates such as the HIV protease substrate have been previously developed as drugs. A similar design concept should also apply to the D-D-peptidase substrate. The long-term objective of this project is to synthesize a series of peptidomimetics of the dipeptide D-alanine-D-alanine. These compounds will be tested for enzyme binding and for antibacterial activity. Various peptidomimetics have been designed and the syntheses of several have been initiated. Linear analogs of D-ala-D-ala containing a carboxylic acid will be synthesized, as will cyclopropyl analogs. Tetrazoles have been used successfully as bioisosteric replacements for the carboxylic acids in a number of drugs. An example is the angiotensin receptor antagonist Losartan. Along those lines, both linear and cyclopropyl analogs of D-ala-Dala containing a tetrazole as a replacement for the carboxylic acid will be synthesized and tested for enzyme binding and antibacterial activity. The proposed compounds constitute an entirely new structural class of potential antibacterials and as such should possess activity against resistant organisms. This would have a significant impact in the ability to treat bacterial infections. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: POLYCYSTIC KIDNEY DISEASE CLINICAL TRIALS NETWORK Principal Investigator & Institution: Chapman, Arlene B.; Professor of Medicine; Medicine; Emory University 1784 North Decatur Road Atlanta, Ga 30322 Timing: Fiscal Year 2002; Project Start 15-AUG-2002; Project End 31-JAN-2009 Summary: (provided by applicant): We seek to be a participating clinical center (PCC) in the RFA entitled "Polycystic Kidney Disease Clinical Trials Network." Hypertension is common, occurs early, and is associated with a faster progression to renal failure in ADPKD. We have shown activation of the systemic renin-angiotensin-aldosterone system (RAAS) in hypertension associated with ADPKD prior to loss of renal function, and that intrarenal activation of RAAS is present. We have demonstrated that angiotensin converting enzyme inhibition alone (ACEI) has beneficial effects by reducing proteinuria and regression of left ventricular hypertrophy as well as

improving effective renal plasma flow, and this may relate to filtration fraction. In contrast to other kidney diseases, ACEI has not been as successful in preventing loss of renal function. This may relate to study design issues, sample size, inclusion of low risk individuals not progressing, and less than maximal blockade of RAAS. Therefore, we propose to assess the effect of combination therapy, i.e. ACEI, angiotensin receptor blockade (ARB), and aldosterone antagonism (spironolactone) in the setting of rigorous blood pressure control (<125/75 mm Hg) on the rate of loss of renal function in ADPKD while controlling for other potential contributors to loss of renal function. ADPKD children with hypertension demonstrate a greater increase in renal volume than other ADPKD children in the setting of normal renal function. Using MRI, we have shown decreased renal blood flow in ADPKD as compared to age and gender-matched children suggesting that activation of RAAS occurs early in ADPKD children. We propose to study a special population of ADPKD subjects (children) throughout adolescence to determine the safety and efficacy of ACE/ARB combination therapy in the acute and chronic setting on renal blood flow, and the rate of renal cyst and total renal growth. Taken together, these studies will determine if maximal inhibition of RAAS prevents loss of renal function in ADPKD adults and if combination ACEI/ARB therapy maintains renal blood flow while slowing renal and cyst growth in ADPKD children. Ultimately these studies should demonstrate slowing or halting progression of ADPKD. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: PPARGAMMA AND AII IN GLOMERULOSCLEROSIS Principal Investigator & Institution: Hsueh, Willa A.; Professor of Medicine and Chief; Medicine; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2002; Project Start 01-JUL-1982; Project End 31-MAR-2004 Summary: An imbalance whereby glomerular extracellular matrix (ECM) production is increased and degradation is decreased leads to a relative and absolute increase in ECM volume in the diabetic mesangium. This crucical alteration impairs glomerular filtering capacity and results in glomerulosclerosis and end-stage renal disease. Plasminogen activator inhibitor-1 (PAI-1) is produced by mesangial cells in response to growth factor stimulation, is increased in glomeruli of diabetic animals and humans and, importantly, is a major factor preventing the degradation of mesangial ECM by inhibiting the activation of plasmin and metalloproteinases (MMP). We identified the presence of novel steroid receptors, which function as heterodimers, peroxisomal proliferatoractivated receptors, PPARgamma, and retinoic acid receptor, RXRalpha, in cultured mesangial cells and in glomerular cores. PPARgamma activation substantially decreased PAI-1 expression, which likely resulted from inhibition of the nuclear effects of the mitogen activated protein kinase (MAPK) pathway. We hypothesize that PPARgamma activation will attenuate the development and progression of diabetic glomerulopathy. Specific aims include: 1) Demonstrate that administration of PPARgamma ligands or

23
novel MAPK inhibitors will prevent glomerular structural changes in rats given streptozotocin (STZ). This aim will determine whether PPARgamma activation affects the glomerulus in vivo, which would support our preliminary data. 2) Define the role of PAI-1 in mediating glomerulosclerosis. This aim will examine changes in the PAI-1 system and MMP in cultured cells and in glomeruli of animal models treated with PPARgamma ligands. Importantly, PAI-1 knockout mice will be given STZ and the development of nephropathy will be compared with that of wild type controls. 3) Investigate the regulation and function of PPARgamma in cultured mesangial cells. This aim will assess whether growth factors or the diabetic milieu alters PPARgamma or RXRalpha expression and examines the effects of receptor activation on mesangial cell growth, apoptosis, ECM and integrin expression. The major contribution of this proposal will be to develop a readily applicable, potential therapeutic approach to inhibit or attenuate the development of diabetic nephropathy by using PPARgamma ligands and to elucidate the mechanism by which activation of these receptors impact on critical cellular signaling pathways.

Project Title: PREVENTION OF COLON CANCER BY AN AT2 RECEPTOR ANTAGONIST Principal Investigator & Institution: Tamura, Masaaki; Biochemistry; Vanderbilt University 3319 West End Ave. Nashville, Tn 372036917 Timing: Fiscal Year 2002; Project Start 01-APR-2001; Project End 31-MAR-2003 Summary: (provided by applicant): Epidemiological studies indicate that a majority of the cases of colorectal cancer are etiologically related to environmental factors. Carcinogenic xenobiotics are activated by phase I biotransformation enzymes. This biotransformation mainly occurs in the liver, but also in extrahepatic tissues. Cytochrome P4501A1, 1A2 and 2E1 (CYP1A1, lA2 and 2E1) are major catalysts in the bioactivation of a number of putative colorectal cancer procarcinogens such as polycyclic aromatic hydrocarbons, heterocyclic amines and N-nitrosoamines. Thus, control of biotransformation enzymes is a potential approach to prevent tumorigenesis in the colon. Recently, we were able to demonstrate that mice deficient in the angiotensin II (Ang II) subtype 2 (AT2) receptor gene are resistant to azoxymethane (AOM)-induced colon adenocarcinoma. AOM-stimulated CYP1A1, 1A2 and 2E1 protein induction in the liver of wild type mice is more significant than in AT2: receptordeficient (AT2-KO) mice. These preliminary studies suggest that Ang II-AT2 receptor signaling may function as a regulator of cytochrome P450 enzyme activities in the liver. Based upon our preliminary studies we hypothesize that 1) Ang II- AT2 receptormediated signaling is involved in the induction of carcinogen- metabolizing cytochrome P450s in the liver and/or colon epithelial cells, 2) attenuation of AT2 receptor function diminishes DNA adduct formation in the liver and colon epithelial cells, and thus 3) the Ang II-AT2 receptor-mediated signal is involved in the initiation of tumorigenesis in the colon. Accordingly, pharmacological attenuation of the AT2 receptor function prevents colon tumorigenesis. In this proposal we place our priority on the chemoprevention of AOM-induced colon cancer. Thus, we propose to determine the effect of blockade of the AT2 receptor function by the AT2 receptor- specific antagonist PD123319 in AOMinduced colon adenocarcinoma and to clarify the mechanism of low susceptibility to AOM in AT2-KO mice. These studies will clarify the role of the Ang II-AT2 receptor in colorectal tumorigenesis and will provide a totally new target for the chemoprevention of colon cancer.

Project Title: REGULATION OF ANGIOTENSIN PEPTIDE RECEPTORS Principal Investigator & Institution: Diz, Debra I.; Professor; Wake Forest University 2240 Reynolda Rd Winston-Salem, Nc 27106 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2003 Summary: Ang-(1-7) activates the vasodilator systems which oppose the hypertensive At1-mediated actions of Ang II. We propose three aims to investigate the potential mechanisms for the actions of Ang-(1-7). Aim 1: A novel non-At1, non-AT2 receptor [AT(1-7)] is responsible for the hemodynamic and vascular actions of Ang-(1-7). 125I[Sar/1-Thr/8]Ang II binding, in the presence of blocking concentrations of AT1 and AT2 receptor antagonists, demonstrated a novel Ang-(1-7) receptive site sit mesenteric artery and aorta of SHR treated with a combination of lisinopril/losartan. The binding site displayed a pharmacological profile with agonists and antagonists that previously characterized in endothelial cells. We will now determine whether this receptor is unique to the vasculature or exhibits a more widespread distribution (kidney, heart and brain) using receptor binding techniques. Aim 2: Ang-(1-7) actions blocked by At1 or AT2 receptor antagonists are not attributable to classical AT1 or AT2 receptors. In addition to the actions of Ang-(1- 7) at the novel non-AT1 non-AT2 AT(1-7) receptor, several actions of Ang-(1-7) are similar to Ang II or are blocked by AT1 or AT2 receptor antagonists. Ang-(1-7) generally displays low affinity for typical AT1 or AT2 receptors and is not associated with vasoconstrictor, pressor or drinking responses. Thus, we propose that isoforms of AT1 or AT2 receptors are responsible for the actions of Ang-(17) that are blocked by AT1 or AT2 receptor antagonists. We will use receptor knockout mice to show that the Ang-(1-7) actions or binding sites inhibited by AT1 or AT2 receptor antagonists do not persist in these receptor knockout animals. We will also characterize the protein forms of At1 and AT2 receptors known to exist in various tissues for differences in pharmacology toward Ang-(1-7) and [D-Ala/7]-Ang-(1-7). Aim 3: Ang-(1-7) counteracts the actions of Ang II at the AT1 receptor by desensitization and/or down-regulation of the AT1 receptor via homologous (through prostaglandins or nitric oxide) mechanisms. Acute and chronic exposure to elevated Ang-(1-7) decreases AT1 receptors and AT1 receptor-mediated responses in brain, kidney and cells in cultured. Prostaglandins causes heterologous down-regulation of other receptors and decrease in AT1 receptor mRNA with nitric oxide are reported. Alternatively, Ang(1-7) acts as a weak agonist at the AT1 receptor, in a process similar to homologous receptor regulation. Preliminary studies in CHO-AT/1A cells indicated a direct effect of Ang-(1-7) on the AT/1A receptor, consistent with agonist-induced homologous downregulation. We will use in vivo and in vitro models to determine the effects of acute and long-term treatments with Ang-(1-7) on AT1 receptor affinity and density and AT1 receptor mRNA by RT-PCR in the presence or absence of cyclooxygenase or nitric oxide synthase blockade.

Project Title: RENIN ANGIOTENSIN SYSTEM BLOCKAGE-DN (RASS) Principal Investigator & Institution: Mauer, S Michael.; Professor; Pediatrics; University of Minnesota Twin Cities 200 Oak Street Se Minneapolis, Mn 554552070 Timing: Fiscal Year 2003; Project Start 16-MAR-1997; Project End 31-MAY-2008 Summary: (provided by applicant): Diabetes nephropathy (DN) is the most important cause of kidney failure. Patients (pts) with Type 1 diabetes mellitus (DM) who develop DN have a markedly increased death rate from kidney failure, coronary artery disease and stroke. Glycemia only partly explains why some pts develop these DM complications. Further, since tight blood sugar control is extremely difficult to maintain, other efforts need to be made to reduce risks of DM complications. Renin-angiotensin system (RAS) inhibitors slow the progress of established DN. The specific aim of this study is to determine whether treatment at the early stages of DM can slow or stop DN structural changes. The long-term objective is to prevent DN from developing. Two hundred eight five pts ages 16-59 with 2-29 yrs of Type 1 DM and no renal functional abnormalities have been randomized into a parallel, double-blind, placebo-controlled study involving 3 groups (95 pts/group). Each group receives an angiotensinconverting enzyme inhibitor (ACEI) (enalapril), or an angiotensin II receptor blocker (losartan), or placebo. All pts have their usual DM management. Baseline studies included measures of glomerular filtration rate (GFR), urinary albumin excretion rate (UAE), blood pressure (BP), and a percutaneous renal biopsy. Pts are followed by quarterly measures of BP, HbA1C, UAE, and drug compliance. There are annual measures of GFR and a repeat renal biopsy after 5 yrs in the study. The main endpoint is kidney structural changes over time, especially mesangial fractional volume [Vv(Mes/glom)]. Secondary endpoints will be other DN structural measures and measures of kidney function (UAE, GFR). These studies will determine whether RAS blockage in the early stages of DN can prevent the early kidney structural changes in this important disorder. Ancillary studies will evaluate the effects of treatment group on the development and progression of diabetic retinopathy and will develop predictors of study participants' compliance.

Project Title: ROLE OF BRAIN RENIN-ANGIOTENSIN SYSTEM IN INSULININDUCED SYMPATHOEXCITATION Principal Investigator & Institution: Muntzel, Martin S.; Herbert H. Lehman College 250 Bedford Park Blvd. West Bronx, Ny 10468 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 30-JUN-2007 Summary: Obesity, syndrome X, and type 2 diabetes are increasing in prevalence and represent major causes of premature morbidity and mortality in westernized socities. The insulin resistance characterizing these diverse pathologies frequently results in a compensatory and sustained hyperinsulinemia. Chronically high insulin, apart from stimulating glucose uptake, has also been shown to be a powerfully activate sympathetic nerve activity (SNA). Importantly, elevated SNA produces several pathophysiological effects, including hypertension, atherosclerosis, ventricular hypertrophy, insulin resistance, and end-organ damage. These actions may partly explain why insulin is powerful and independent predictor of atherosclerosis and cardiovascular events. It remains unclear, however, what mechanisms mediate the excitatory effect of insulin on SNA. We and others have examined the possibility that insulin activates brain renin-angiotensin to then cause increases in sympathetic outflow. This hypothesis is based on the following evidence: 1) systemically-infused insulin increases SNA, 2) insulin penetrates into the brain to bind with insulin-specific receptors, 3) direct administration of insulin into the brain increases lumbar SNA, 4) insulin activates several components of the renin-angiotensin system, 5) insulin-induced SNA elevations are abolished by systemic or by intracerebroventricular reninangiotensin blockade, 6) insulin-activated sympathetic increases are also abolished by lesions of the anteroventral third ventricle (AV3V) region, which is a primary site for the sympathoexcitatory actions of angiotensin II, and 7) renin-angiotensin pathways from AV3V nuclei to the paraventricular nucleus (PVN) exert powerful control over sympathetic output. Altogether, these findings indicate that insulin-induced sympathoexcitation is dependent upon components of the brain renin-angiotensin system. To extend these findings, the present studies will first, determine whether angiotensin II receptor antagonism in the organum vasculosum of the lamina terminalis (OVLT), the median preoptic nucleus (MnPO), and PVN abolish increases in SNA to acute insulin, and second, will determine whether chronic SNA increases, activated by long-term insulin infusion or by high dietary fructose, are abolished by inhibition of brain renin-angiotensin using intracerebroventricular losartan. Finally, we will determine whether physiologically generated modulations of renin-angiotensin function, produced by altering dietary sodium intake, will affect acute sympathoexcitatory responses to insulin. By demonstrating the precise role of brain renin-angiotensin in eliciting SNA increases to hyperinsulinemia, the present experiments will provide fundamental new information regarding central neural regulation of autonomic output. In addition, these findings will generate new hypotheses for intervention strategies to prevent the deleterious consequences of sympathoexcitation in disease states characterized by insulin resistance and hyperinsulinemia.

Project Title: TACROLIMUS VS INTENSIVE PREDNISONE IN PEDIATRIC FSGS Principal Investigator & Institution: Kaskel, Frederick J.; Developmental Renal and Electrolyte Phys; Montefiore Medical Center (Bronx, Ny) Bronx, Ny 104672490 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): Focal Segmental Glomerulosclerosis (FSGS) is a major cause of chronic kidney disease in childhood. This glomerulopaty is more frequent in minority populations, and often recurs in the transplanted kidney. Despite advances particulary in molecular genetics, the cause and optimal treatment of this condition remains poorly defined. Uncontrolled studies in adults with FSGS support the use of prolonged prednisone therapy. Preliminary data in children suggests that the calcineurin inhibitor tacrolimus may be efficacious in patients who have been refractory to other therapies. The purpose of this multicenter study is to compare the relative efficacy of tacrolimus with that of intensive prednisone therapy in preventing the progression of primary FSGS. This represents the first controlled evaluation of these two promising therapies in children with FSGS. We are proposing a randomized, open-label clinical trial in patients with nephrotic range proteinuria who fail to respond to 4 weeks of oral prednisone and who are found to have FSGS on renal biopsy. Patients will be assigned to receive daily prednisone (60 mg/m2) for 3 months followed by either alternate day prednisone (40 mg/m2) for the ensuing 15 months or tacrolimus plus lowdose alternate day (10 mg/m2) for 18 months. In addition, patients will receive optimal doses of losartan and atorvostatin to control proteinuria, hypertension, and hypelipidemia. The primary outcome indicators will be: complete or partial remission of proteinuria, preservation of glomerular filtration rate, and prevention of renal scarring. Secondary outcome indicators will include correlation of response with a novel histopathologic classification, assessed by a centrol core pathology group. The study design will incorporate collection and storage of potentially important biological samples at the direction of the Data Coordinating Center and the Steering Committee of the NIDDK. The Eastern Regional Group for the Study of Focal Segmental Glomerulosclerosis in Children will be comprised of 41 sites under the direction of the Regional Coordinating Center at Montefiore Medical Center of the Albert Einstein College of Medicine. This project is expected to: 1) improve the outcome of children with FSGS, and, 2) create a nationwide network of clinical investigators that will facilitate future basic and clinical research in the field of pediatric nephrology, in general, and FSGS, in particular.

Summary: Glucuronide formation is a major route of xenobiotic and endobiotic metabolism in humans. UDP-glucuron-osyltransferases (UGTs), protein products of a supergene family, mediate these reactions whereby hydrophobic compounds (aglycones) are conjugated to glucuronic acid, forming metabolites which are rapidly excreted by the kidney or liver. Four areas of research are planned. First, the significance of the polymorphic isoforms of UGT2B7 in the metabolism of certain substrates (losartan and zidovudine) will be explored using HK293 cell lines stable expressing these proteins. Using hepatic microsomes from individuals homozygous for these polymorphic isoforms, studies will address the question of whether inter-individual variation in AZT glucuronidation can be predicted base don the genotype of the individual. mRNA and glucuronidation activities for UGT2B7 and UGT1A6 have been found in human brain. Studies are proposed to use immunohistochemical localization to identify the cell types that express these proteins in the brain. Since immunohistochemical localization to identify the cell types that express these proteins in the brain. Since UGT2B7 catalyzes the formation of morphine-6-glucuronide (which is 50 times more potent that morphine as an analgesic) it is important to know where in the rain morphine-6-glucuronide can be formed because its local formation may account for part of the mechanism of action of morphine. Studies determining the substrate specificities of UGTs expressed in intestine, 1A8 and 1A5, are proposed. These isoforms are not expressed in liver and, therefore, may play an important role in xenobiotic and endobiotic metabolism in the intestine. UGT1A4 is an important enzyme because it catalyzes the glucuronidation of tertiary amines (e.g., anti-histamines) and progestins, whereas UGT1A3 catalyzes the glucuronidation of estrogens and NSAIDs. Studies are proposed that will investigate how the protein structure of UGT1A3 and UGT1A4 affects the function of the expressed enzymes. Chimeric proteins and amino acid substitutions will examine the aglycone binding sites for substrates which are unique to each protein and which are common for each UGT.

Experiment also will be proposed in vitro using cultured aortic adventitial fibroblasts to determine if a molecular basis for the in vivo responses that occur can be explained at a cellular level. The in vitro studiers will focus on signaling pathways that mediate the vascular responses to ang II and catecholamines under conditions of reduced or exacerbated oxidative stress. The specific aims are: 1) To catecholamines under conditions of reduced or exacerbated oxidative stress. The specific aims are: 1) To extend our previous studies on the role of AT1 and alpha1-adrenergic receptor blockade by losartan and prazosin in slowing the development of atherosclerosis in the apoprotein E-deficient mouse. A hypothesis to be tested is that the alpha2-adrenergic response may be influential in reducing the vascular response to hypercholesterolemia that characterizes this mouse model. 2) To characterize the cardiovascular responses to chronic infusion of both ang II and catecholamines in mice, and to determine what effect

oxidative stress has on these responses. Changes in cardiac tissue will be measured using biochemical and morphometric techniques and correlated with vasoactive responses. The interrelationships between ang II and catecholamines will be emphasized, using selective antagonists to the receptors for each endocrine system, or by using receptor-deficient mice that are current available. Possible interactions between responses induced by ang II and the alpha2-adrenergic receptor will be examined with regard to cardiac damage as well as the hemodynamic changes. 3) To evaluate the role of ang II, catecholamines, and nitric oxide (NO) on the activation of mitogen activated protein kinases (MAPK) and the expression of p231 in cultured adventitial fibroblasts. The adventitial fibroblast is proposed to be an important cell type in modulating vascular responses to vasoactive agents and its response to NO may influence vascular responses to other agonists. A specific hypothesis to be tested is if interrelationships between MAPK and p21 expression is influenced by ang II, catecholamines, NO, or oxidative stress.

Project Title: VASOACTIVE HORMONES: RECEPTORS AND SIGNALING MECHANISM Principal Investigator & Institution: Hopfer, Ulrich; Professor; Medicine; Case Western Reserve University 10900 Euclid Ave Cleveland, Oh 44106 Timing: Fiscal Year 2002; Project Start 01-JUL-1989; Project End 30-APR-2005 Summary: The renin-angiotensin system regulates blood pressure and fluid homeostasis through effects mediated by specific receptors that are widely distributed. Molecular biological and pharmacological observations have confirmed the existence of two major subtypes of angiotensin II receptors: AT1 receptors that are highly sensitive to biphenylimidazoles (e.g. losartan), and AT2 receptors that are sensitive to tetrahydroimidopyridines (e.g. PD 123319). Abundant physiological and pharmacological data have been accumulated to substantiate the observation that the AT1 receptor mediates a majority of the known effects of Ang II. By contrast, much less is known about AT1 mediated effects, however, it is generally accepted that there is a "yin yang" relationship. Functional data indicate that the AT2 receptor opposes the blood pressure elevation of the AT1 receptor and other cellular actions as well. Data is now accumulating that a major mechanism whereby the AT2 receptor regulates blood pressures is through its ability to facilitate Na excretion. The overall goal of the PPG is to elucidate cellular/molecular mechanisms important for the regulation of blood pressure through effects on ion transport. The central hypothesis is that the AT2 receptor in the proximal tubule is responsible for diminished salt and fluid reabsorption that is observe in high physiological concentrations of angiotensin II. To test this hypothesis, we have assembled three projects that are directed at gaining a better understanding of structural/functional aspects of angiotensin receptors and cellular signaling pathways with influences on cytoskeleton and ion transporters in kidney epithelium. Attainment of this goal necessitates a multi- disciplinary group encompassing cell/organ physiology, molecular biology, biochemistry, pharmacology, biophysics and genetics. The program stresses a broad application to the problem of receptors, effectors, and coupling mechanisms to downstream targets employing cells and subcellular organelles and emphasizes and application of state- of-the-art techniques. Studies at a whole animal level will involve continuous infusions, assessments of blood pressure, and selective breeding of transgenic mice. Studies at a cellular level will utilize electrophysiology, fluorescent probes, pH measurement, and confocal microscopy. Studies at a molecular level involve cloning receptor subtypes, transfections of receptors

E-Journals: PubMed Central3 PubMed Central (PMC) is a digital archive of life sciences journal literature developed and managed by the National Center for Biotechnology Information (NCBI) at the U.S. National Library of Medicine (NLM).4 Access to this growing archive of e-journals is free and unrestricted.5 To search, go to http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=Pmc, and type “losartan” (or synonyms) into the search box. This search gives you access to fulltext articles. The following is a sample of items found for losartan in the PubMed Central database: •

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 losartan, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “losartan” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for losartan (hyperlinks lead to article summaries): 3 4

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. 6 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 LOSARTAN Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and losartan.
Finding Nutrition Studies on Losartan 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 “losartan” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Recent Trials on Losartan The following is a list of recent trials dedicated to losartan.8 Further information on a trial is available at the Web site indicated. •
Long Term Effects of Enalapril and Losartan on Genetic Heart Disease Condition(s): Hypertrophic Myocardial Ischemia
Cardiomyopathy;
Left
Ventricular
Hypertrophy;
Study Status: This study is completed. Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) Purpose - Excerpt: The human heart is divided into four chambers. One of the four chambers, the left ventricle, is the chamber mainly responsible for pumping blood out of the heart into circulation. Hypertrophic cardiomyopathy (HCM) is a genetically inherited disease causing an abnormal thickening of the heart muscle, especially the muscle making up the left ventricle. When the left ventricle becomes abnormally large it is called left ventricular hypertrophy (LVH). This condition can cause symptoms of chest pain, shortness of breath, fatigue, and heart beat palpitations. This study is designed to compare the ability of two drugs (enalapril and losartan) to improve symptoms and heart function of patients diagnosed with hypertrophic cardiomyopathy (HCM). Researchers have decided to compare these drugs because each one has been used to treat patients with other diseases causing thickening of the heart muscle. In these other conditions, enalapril and losartan have improved symptoms, decreased the thickness of heart muscle, improved blood flow and supply to the heart muscle, and improved the pumping action of the heart muscle. In this study researchers will compare the effectiveness of enalapril and losartan when given separately and together to patients with hypertrophic cardiomyopathy (HCM). 8

Keeping Current on Clinical Trials The U.S. National Institutes of Health, through the National Library of Medicine, has developed ClinicalTrials.gov to provide current information about clinical research across the broadest number of diseases and conditions. The site was launched in February 2000 and currently contains approximately 5,700 clinical studies in over 59,000 locations worldwide, with most studies being conducted in the United States. ClinicalTrials.gov receives about 2 million hits per month and hosts approximately 5,400 visitors daily. To access this database, simply go to the Web site at http://www.clinicaltrials.gov/ and search by “losartan” (or synonyms). While ClinicalTrials.gov is the most comprehensive listing of NIH-supported clinical trials available, not all trials are in the database. The database is updated regularly, so clinical trials are continually being added.

CHAPTER 4. PATENTS ON LOSARTAN 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.9 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 “losartan” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on losartan, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Losartan By performing a patent search focusing on losartan, 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

Losartan
will tell you how to obtain this information later in the chapter. The following is an example of the type of information that you can expect to obtain from a patent search on losartan: •
Composition of enalapril and losartan Inventor(s): Chen; Tzyy-Show H. (Lansdale, PA), Grossman; William (San Francisco, CA), Iskandarani; Bassel (Lansdowne, PA), Krammer; Kenneth A. (Green Lane, PA), Sweet; Charles S. (Doylestown, PA) Assignee(s): Merck & Co., Inc. (rahway, Nj) Patent Number: 6,087,386 Date filed: June 17, 1997 Abstract: The present invention discloses a pharmaceutical composition of enalapril and losartan and a pharmaceutically acceptable carrier. Excerpt(s): Angiotensin II (AII) is a potent vasoconstrictor. Its generation in the reninangiotensin cascade results from the enzymatic action of renin on a blood plasma.alpha.2-globulin, angiotensinogen, to produce angiotensin I (AI). AI is then converted by angiotensin converting enzyme (ACE) to the octapeptide hormone AII. AII has been implicated as a causitive agent in hypertension. Therefore, ACE inhibitiors, which inhibit the production of AII via angiotensin converting enzyme, and AII receptor antagonists, which inhibit the function of AII, no matter the pathway of biosynthesis, are useful in the treatment of hypertension. The efficacy of these compounds in the treatment of heart failure is also being studied. Pals, et al., Circulation Research, 29, 673 (1971) describe the introduction of a sarcosine residue in position 1 and alanine in position 8 of the endogenous vasoconstrictor hormone AII to yield an octapeptide that blocks the effects of AII on the blood pressure of pithed rats. This analog, [Sar.sup.1, Ala.sup.8 ] AII, initially called "P-113" and subsequently "saralasin," was found to be one of the most potent competitive antagonists of the actions of AII, although, like most of the so-called peptide-AII-antagonists, it also possesses agonistic actions of its own. Saralasin has been demonstrated to lower arterial pressure in mammals and man when the (elevated) pressure is dependent on circulating AII (Pals et al., Circulation Research, 29, 673 (1971); Streeten and Anderson, Handbook of Hypertension, Vol. 5, Clinical Pharmacology of Antihypertensive Drugs, A. E. Doyle (Editor), Elsevier Science Publishers B. V., p. 246 (1984)). However, due to its agonistic character, saralasin generally elicits pressor effects when the pressure is not sustained by AII. Being a peptide, the pharmacological effects to saralasin are relatively short-lasting and are only manifest after parenteral administration, oral doses being ineffective. Although the therapeutic uses of peptide AII-blockers, like saralasin, are severely limited due to their oral ineffectiveness and short duration of action, their major utility is as a pharmaceutical standard. Some known non-peptide antihypertensive agents act by inhibiting an enzyme, called angiotensin converting enzyme (ACE), which is responsible for conversion of angiotensin I to AII. Captopril and enalapril are commercially available ACE inhibitors (ACEI's). Based on experimental and clinical evidence, about 40% of hypertensive patients are non-responsive to treatment with ACEI's. But when a diuretic such as furosemide or hydrochlorothiazide is given together with an ACEI, the blood pressure of most hypertensive patients is effectively normalized. Diuretic treatment converts the non-renin dependent state in regulating blood pressure to a renin-dependent state. Although AII antagonist compounds act by a different mechanism, i.e., by blocking the AII receptor rather than by inhibiting the angiotensin converting enzyme, both mechanisms involve interference with the renin-
Patents 91
angiotensin cascade. A combination of the ACEI enalapril maleate and the diruetic hydrochlorothiazide is commercially available under the trademark Vaseretic.RTM. from Merck & Co. Publications which relate to the use of diuretics with ACEI's to treat hypertension, in either a diuretic-first, stepwise approach or in physical combination, include Keeton, T. K. and Campbell, W. B., Pharmacol. Rev., 31:81 (1981) and Weinberger, M. H., Medical Clinics N. America, 71:979 (1987). Diuretics have also been administered in combination with saralasin to enhance the antihypertensive effect. Web site: http://www.delphion.com/details?pn=US06087386__ •
Crystalline or crystallized acid addition salt of losartan and purification method of losartan Inventor(s): Itaya; Nobushige (Osaka, JP), Katsura; Tadashi (Osaka, JP), Shiratani; Hiroshi (Osaka, JP) Assignee(s): Sumika Fine Chemicals Co., Ltd. (osaka, Jp) Patent Number: 6,350,880 Date filed: November 16, 2000 Abstract: The present invention provides a crystalline or crystallized acid addition salt of Losartan useful for obtaining highly pure 2-n-butyl-4-chloro-1-[[2'-(1H-tetrazol-5yl)[1,1'-biphenyl]-4-yl]methyl]-1 H-imidazole-5-methanol (Losartan), and a purification method of Losartan that includes production of the crystalline or crystallized acid addition salt. Excerpt(s): The present invention relates to a novel crystalline or crystallized acid addition salt of Losartan, which has a superior antagonistic activity against angiotensin II, and to a purification method of Losartan, which comprises producing the crystalline or crystallized acid addition salt. (hereinafter to be also referred to as Losartan) is a useful antihypertensive agent having a superior antagonistic activity against angiotensin II. Losartan is generally used in the form of a potassium salt. Inasmuch as purification of a potassium salt is not feasible, it is a typical practice to purify free Losartan to a high degree first and then convert it to a potassium salt. However, purification of Losartan itself is also difficult and there are some purification methods proposed to achieve a higher purity of Losartan (WO93/10106, WO95/17396 etc.). These methods, nevertheless, are not entirely satisfactory and a feasible purification method to increase the purity of Losartan has been demanded.

In rat heart two days post-MI it has also been shown that both the left and right ventricles become more sensitive to treatment with AII resulting in reduced mechanical performance and that this negative effect can be blocked by co-administration of losartan ›See Capasso, J. M., et al., "Alterations in ANG II Responsiveness in Left and Right Myocardium after Infarction-induced Heart Failure in Rats", Am. J. Physiol., 1993, Vol. 264(33) pp. H2056-H2067!. Also in the rat, AII AT.sub.1 receptor binding density in infarcted heart was recently shown to increase significantly as early as 3 days post-MI ›See Sun, Y., et al., "Angiotensin II Receptor Binding Following Myocardial Infarction in the Rat", Cardiovascular Research, 1994; Vol. 28. pp. 1623-1628!. These recent experimental observations may have clinical implications as to the usefulness of losartan in the treatment of infarction induced heart failure. The importance of using a physiological preparation for the study of AII receptor antagonism should be emphasized because it has recently been shown that donor tissue from rat atria experiences an almost complete loss of AT.sub.2 receptors during isolation and culturing while the expression of AT.sub.1 receptors in cultured ventricular cells may be up-regulated by the culture conditions ›See Feolde, E., et al., "Angiotensin II Receptor Subtypes and Biological Responses in the Rat Heart", J. Mol. Cell. Cardiol., 1993, Vol. 25, pp. 1359-1367!. On the other hand, use of in vivo experimental models of myocardial ischemia to study the cardiac renin-angiotensin system (RAS) may give results in which it is difficult to differentiate the influence of the local cardiac RAS from circulating AII effects ›See de Graeff, P. A., et. al., "The Cardiac Renin-Angiotensin System in Different Ischemic Syndromes of the Heart. In: Lindpaintner, K. and Ganten, D., eds.

The benefits of ACE inhibitors have been attributed to blockade of angiotensin II production and/or to a decrease in the breakdown of bradykinin. (See Pitt B, Chang P, Timmermans P. Angiotensin II receptor antagonists in heart failure: Rationale and design of the Evaluation of Losartan in the Elderly (ELITE) Trial. Cardiovascular Drugs and Therapy 1995; 9: 693-700; and Gavras I. Bradykinin-mediated effects of ACE inhibition. Kidney Int 1992; 42:1020-1029.) Bradykinin has been shown to have beneficial effects associated with the release of nitric oxide and prostacyclin which may contribute to the hemodynamic effects of ACE inhibition. Bradykinin may, however, also be responsible for certain adverse effects associated with use of ACE inhibitors, such as cough, angioedema, renal dysfunction, and hypotension.

These adverse effects may account in part for the fact that ACE inhibitors are used in less than 30 percent of patients with heart failure in spite of their proven clinical benefit.

Abstract: The method of treatment moderating, blocking and/or eliminating premenstrual syndrome embodies the intermittent administering of an AT1 antagonist to a female having menstrual cycles characterized predominately by during substantially the luteal phase inclusive of at least one and frequently by two or more affective and/or autonomic and/or somatic symptoms of substantially incapacitating severity(ies) proximately substantially prior to menses of a menstrual cycle. Losartan is an example of an AT1 inhibitor and is administered either orally or parenterally continuously to a female during her menstrual cycle's luteal phase. Excerpt(s): This invention is directed to a method of treatment for obviating and/or blocking premenstrual tension syndrome on an interim basis during the luteal phase of a menstrual cycle of a patient suffering from premenstrual syndrome characterized by a concurrent plurality of symptoms inclusive of affectlye and/or autonomic and/or somatic symptoms cumulatively of substantially incapacitating severity prior to the menses. United States Patent to Blankley, C. J., et. al., U.S. Pat. No. 5,246,943 granted Sep. 21, 1993 states in sections 3 line 40 that "excessive secretion of AVP (vasopressin, also known as antidiuretic hormone) as been linked to a number of disorders including excessive water retention associated with the female reproductive disorder known as premenstrual syndrome (PMS) (Janowski, et.al., Psychosomatic Medicine 35:143-154 (1973)". The authors claim that compounds which block angiotensin II subtype 2 (AT2) receptors induced AVP secretion are therefore, useful in treating the above disorders. The abovementioned article of Janowsky does not suggest nor even specifically mention AVP as a cause of PMS. Janowski, et. al. describes an increase in the retention of sodium (Na) with a subsequent retention of water. Janowski, et. al. correlated the similarity of their findings to the physiologically known effects of aldosterone. In fact, a rise in body sodium would cause a decrease in AVP secretion. Ganong, W. F., in his textbook of physiology (1987) clearly states on Page 607, "the amount of sodium in the ECF (extracellular fluid) is the most important determinant of ECF volume. rise in ECF volume inhibits vasopressin (AVP) secretion. Volume stimuli override the osmotic regulation of vasopressin secretion." More importantly, is the fact that no correlation exists between circulating levels or changes in circulating levels of AVP aldosterone or any other hormone and the appearance of the symptoms of PMS. (Reid, R. L.: Premenstrual Syndrome: Current Problems in Obstetrics, Gynecology and Fertility, February, Vol. VIII, No. 2, 1985). Additionally when an AT2 receptor antagonist (PD123319) was administered to dogs, it had no effect on circulating vasopressin levels. (Keiser, J. A., et. al., Renal Hemodynamic and Excretory Responses to PD123319 and Losartan Nonpeptide AT1 and AT2 Subtype Specific Angiotension II ligands, J. Pharmacol. Exp. Ther., September 1992; 263(3): 1154-60. In addition, there are no differences in any of the measured hormonal changes between PMS and non-PMS patient. In addition, Blankley, et. al. in section 2, line 51 declare that their invention refers specifically to agents that block the angiotension II subtype 2 (AT2) receptors found in the central nervous system of mammals and the compounds described are supposedly effective in blocking only the binding of angiotension II (Ang II) at AT2 receptors. They claim that various disorders including neurologic, psychiatric, neuroendocrine, neurodegenerative and neuroimmunological disorders including addiction, anxiety, depression, epilepsy, hyperactivity, memory, pain, psychosis, regulation of autonomic functions and sleep are included in their patent only when regulated by AT2 receptors. A study evaluating the effects of blocking AT1 and AT2 receptors on sympathetic (autonomic) nervous system function and effects of intravenously administered norepenephrine (NE) showed that blocking the subtype 2 receptor (using PD123177) did not modify the effects of intravenous NE nor modify effects of sympathetic nervous system stimulation, thus showing that there are distinct

fibroids appear in the reproductive years and regress after the menopause. Uterine fibroids are most commonly treated by surgery, usually by full or partial hysterectomy, although removal of individual fibroids (myomectomy) is also undertaken at rather greater risk on women who have not completed child bearing. As far as medical treatment is concerned, agonist analogues of LHRH (luteinizing hormone-releasing hormone) such as Buserilin (GnRH analogue) have been employed to suppress oestrogen-progesterone as fibroids are ovarian steroid dependent. Such medical treatments, however, suffer from a variety of side effects such as predisposition to osteopetrosis and are not recommended for long term use.

Method of treatment Inventor(s): Brenner, Barry M.; (Weston, MA), Shahinfar, Shahnaz; (Newton Square, PA), Zhang, Zhongxin; (Blue Bell, PA) Correspondence: Merck And CO Inc; P O Box 2000; Rahway; NJ; 070650907 Patent Application Number: 20030073705 Date filed: May 10, 2002 Abstract: This disclosure relates to a method of preventing end stage renal disease using an angiotensin II antagonist in patients with impaired renal function. Angiotensin II antagonists such as candesartan cilexetil, eprosartan, irbesartan, losartan, tasosartan, telmisartan, valsartan, 2-butyl-4-chloro-1-[(2'-tetrazol-5-yl)biphenyl-4yl)methyl]imidazolecarbo- xylic acid and 3-(2'-(tetrazol-5-yl)-1,1'-biphen-4-yl)methyl5,7-dimethyl-- 2-ethyl-3H-imidazo[4,5-b]pyridine, or pharmaceutically acceptable salts thereof are useful. Excerpt(s): Angiotensin II (AII) is a potent vasoconstrictor. Its generation in the reninangiotensin cascade results from the enzymatic action of renin on a blood plasma, 2globulin, angiotensinogen, to produce angiotensin I (AI). AI is then converted by angiotensin converting enzyme (ACE) to the octapeptide hormone, AII. AII has been implicated as a causitive agent in hypertension. Therefore, ACE inhibitiors, which inhibit the production of AII, and AII receptor antagonists, which inhibit the function of AII, are useful in the treatment of hypertension. The efficacy of these compounds in the treatment of heart failure is also being studied. Pals, et al., Circulation Research, 29, 673 (1971) describe the introduction of a sarcosine residue in position 1 and alanine in position 8 of the endogenous vasoconstrictor hormone AII to yield an (octa)peptide that blocks the effects of AII on the blood pressure of pithed rats.

AII, initially called "P-113" and subsequently "Saralasin," was found to be one of the most potent competitive antagonists of the actions of AII, although, like most of the socalled peptide-AII-antagonists, it also possesses agonistic actions of its own. Saralasin has been demonstrated to lower arterial pressure in mammals and man when the (elevated) pressure is dependent on circulating AII (Pals et al., Circulation Research, 29, 673 (1971); Streeten and Anderson, Handbook of Hypertension, Vol. 5, Clinical Pharmacology of Antihypertensive Drugs, A. E. Doyle (Editor), Elsevier Science Publishers B. V., p. 246 (1984)). However, due to its agonistic character, saralasin generally elicits pressor effects when the pressure is not sustained by AII. Being a peptide, the pharmacological effects to saralasin are relatively short-lasting and are only manifest after parenteral administration, oral doses being ineffective. Although the therapeutic uses of peptide AII-blockers, like saralasin, are severely limited due to their oral ineffectiveness and short duration of action, their major utility is as a pharmaceutical standard. Some known non-peptide antihypertensive agents act by inhibiting an enzyme, called angiotensin converting enzyme (ACE), which is responsible for conversion of angiotensin I to AII. Captopril and enalapril are commercially available ACE inhibitors (ACEI's). Based on experimental and clinical evidence, about 40% of hypertensive patients are non-responsive to treatment with ACEI's. But when a diuretic such as furosemide or hydrochlorothiazide is given together with a CEI, the blood pressure of the majority of hypertensive patients is effectively normalized.

Methods of treatment using a gastric retained losartan dosage Inventor(s): Cumming, K. Iain; (Dublin, IE), Devane, John; (Athlone, IE), Gusler, Gloria M.; (Cupertino, CA), Hou, Sui Yuen Eddie; (Foster City, CA) Correspondence: Cooley Godward, Llp; 3000 EL Camino Real; 5 Palo Alto Square; Palo Alto; CA; 94306; US Patent Application Number: 20030158244 Date filed: October 25, 2002 Abstract: A method of treatment for hypertension and other disease states is described, which comprises the delivery of losartan in a gastric retained dosage form. Excerpt(s): The present invention relates to the use of losartan in a gastric retained dosage form. More specifically, the invention relates to the use of such dosage form to treat hypertension and other disease states. Losartan was the first orally active angiotensin II receptor antagonist (McIntyre, et al., Pharmacol. Ther. 74(2):181-194 (1997); Siegel, Journal of Hypertension 11(3):S19-S22 (1993)). At present, losartan is marketed as losartan potassium (C.sub.22H.sub.22ClKN.sub.6O), which is chemically described as 2-butyl-4-chloro-1[p-(o-1H-tetrazol-5-yl- phenyl) benzyl]imidazole-5methanol monopotassium salt. Losartan potassium is administered to treat hypertension and is commercially available in 25 mg, 50 mg and 100 mg tablet dosage forms. Dosage regimens are typically 25 mg to 100 mg either once- or twice-daily. The effects of losartan potassium are observed at 24 hours for both the 50 mg and the 100 mg dosages, but not for the 25 mg dosage (McIntyre, et al., supra). McIntyre also observes that there is an approximately 30% blockade of the diastolic pressure response to angiotensin II at 24 hours after dosing. Further, the peak:trough blood pressure ratio (5-6 hours after dosing: 24 hours after dosing) was found to be 60% for a 50 mg dosage and 72% for a 100 mg dosage.

Process for the synthesis of a known tetrazol derivative Inventor(s): Bagdy, Judit Nagyne; (Budapest, HU), Ballo, Ildiko; (Budapest, HU), Czibula, Laszlo; (Budapest, HU), Farkas, Jen?ouml;me; (Budapest, HU), Fischer, Janos; (Budapest, HU), Hegedus, Istvan; (Budapest, HU), Juhasz, Ida Deutschne; (Budapest, HU), Kreidl, Janos; (Budapest, HU), Nemes, Andras; (Budapest, HU), Petenyi, Endrene; (Budapest, HU), Werkne Papp, Eva; (Budapest, HU) Correspondence: The Firm OF Karl F Ross; 5676 Riverdale Avenue; PO Box 900; Riverdale (bronx); NY; 10471-0900; US Patent Application Number: 20030078435 Date filed: July 24, 2002 Abstract: The invention relates to a process for the synthesis of losartan potassium of formula (I), chemical name: 2-n-butyl-4-chloro-1-[(2'-(tetrazol-5-yl)-- 1,1'biphenyl-4-yl)methyl]-imidazol-5-methanol potassium, starting from 2-n-butyl-4-chloro-1-[(2'-(2triphenylmetyl-2H-tetrazol-5-yl)-1,1'-biphen- yl-4-yl)-methyl]-1H-imidazol-4-methanol of formula (III). According to the process the compound of formula (III) is reacted in an alcohol of formula (VI),--wherein the meaning of R is C.sub.1-C.sub.4 straight chain alkyl group--with 0.1-1 equivalent of potassium hydroxide. The final product of formula (I) is isolated after crystallizing out by changing the solvent to an aprotic or weakly protic solvent (I). Excerpt(s): In the examples of the above patent applications the detritylation was carried out either with aqueous hydrochloric acid or with aqueous sulfuric acid in the presence of tetrahydrofuran or acetonitrile. The total yield of losartan potassium was 72 or 80% from the acidic compound of formula (II), which was isolated after complicated operations. The disadvantages of this process are that the transformation can be carried out only in two steps, the cleavage of the trityl group proceeds by strong, corrosive mineral acid--hydrochloric acid or sulfuric acid--solution and the desired losartan potassium was isolated after addition of aqueous potassium hydroxide with complicated operations: azeotropic distillation, in low yield. It is known, that during the synthesis of other biphenyltetrazolyl compounds, for example according to U.S. Pat. No. 5,281,603, the trityl protecting group was cleaved by catalytic amount of acid in organic solvents. According to an other known procedure, for example the one described in the U.S. Pat. No. 5,281,604, the trityl group of a tetrazolyl-quinazolinone derivative is cleaved by refluxing in a mixture of methanol and tetrahydrofuran for 18 hours. The purified acidic tetrazol derivative was obtained after concentration of the reaction mixture by complicated column chromatography in low yield. From this tetrazol derivative the desired salts can be formed by known procedures. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Losartan
Processes for preparing losartan and losartan an potassium Inventor(s): Dolitzky, Ben-Zion; (Petach Tiqva, IL) Correspondence: Kenyon & Kenyon; 1500 K Street, N.W., Suite 700; Washington; DC; 20005; US Patent Application Number: 20040034077 Date filed: April 29, 2003 Abstract: Losartan is prepared by acid catalyzed cleavage of a triarylmethyl group from a triarylmethyl-substituted losartan derivative in a diluent comprising liquid ketone. The reaction mixture is basified and liquid ketone is evaporated from the mixture leaving a residue from which a triarylmethyl alcohol and losartan are each obtained in high yield and high purity. In addition, losartan potassium is prepared by a process that is more convenient that those previously known in the art in which losartan is contacted with potassium ions in substantially pure liquid alcohol and losartan potassium is precipitated from the alcohol. Excerpt(s): This application claims the benefit under 35 U.S.C.sctn.119(e) of provisional application Serial No. 60/376,322, filed Apr. 29, 2002 which is incorporated herein by reference. The present invention relates to therapeutic agents that inhibit angiotensin II binding to AT.sub.1 receptors and, more particularly, to a process for preparing the AT.sub.1 receptor antagonist losartan. Activation of AT.sub.1 receptors in the outer membrane of vascular smooth muscle cells of the heart and arteries causes those tissues to constrict. Blocking of vasoconstriction mediated by AT.sub.1 receptors has been found to be beneficial to patients with hypertension. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Use of an angiotensin II receptor antagonist for the preparation of drugs to increase the survival rate of renal transplant patients Inventor(s): Remuzzi, Giuseppe; (Bergamo, IT) Correspondence: Browdy And Neimark, P.L.L.C.; Sutie 300; 624 Ninth Street, N.W.; Washington; DC; 20001-5303; US Patent Application Number: 20020115702 Date filed: February 19, 2002 Abstract: The present invention relates to the use, for the preparation of drugs to increase the survival rate of transplant patients, including renal and heart transplant patients, of a therapeutically effective amount of an angiotension II receptor antagonist compound, such as the class of substituted imidazoles represented by formula (I) and in particular by losartan potassium, 2-butyl-4-chloro-[(2'-tetrazol-5-yl)biphenyl-4-il]methyl]-5-(hydroxymethyl)imidazole potassium salt. Excerpt(s): This invention relates to the use of an angiotensin II receptor antagonist, such as substituted imidazole compounds, for the treatment of Post-transplant hypertension. The invention also relates to use of an angiotensin II receptor antagonist, such as substituted imidazole compounds, for the preparation of drugs to increase the survival rate of transplant patients, including renal transplant patients. The invention also relates to a method of using an angiotensin II receptor antagonist, such as substituted for increasing the survival rate of transplant patients, including renal transplant patients. Substituted imidazoles of formula I are known to inhibit the action of the octapeptide
Patents 101
hormone angiotensin II (AII) and are useful therefore in alleviating angiotensin induced hypertension. The enzyme renin acts on a blood plasma.alpha.2-globulin, angiotensinogen, to produce angiotensin I, which is then converted by angiotensin converting-enzyme to AII. The latter substance is a powerful vasopressor agent which has been implicated as a causitive agent, for producing high blood pressure in various mammalian species, such as the rat, dog, and man. The compounds disclosed in this application inhibit the action of AII at its receptors on target cells and thus prevent the increase in blood pressure produced by this hormone-receptor interaction. The present application discloses a method for the improvement of insulin sensitivity by administering an angiotensin II receptor antagonist, such as a substituted imidazole of formula I, to a species of mammal with hypertension due to angiotensin II. Administration of an angiotensin II receptor antagonist, such as a substituted imidazole of formula I, with a diuretic, such as furosemide or hydrochlorothiazide; either as a stepwise combined therapy (diuretic first) or as a physical mixture, enhances the antihypertensive effect of the compound, while also improving the insulin sensitivity of the patient. wherein R1 is hydrogen, nitro or amino; R2 is phenyl, furyl or thienyl optionally substituted by halogen, lower alkyl, lower alkoxy or di-lower alkylamino; R3 is hydrogen or lower alkyl and X is halogen; and their physiologically acceptable salts. These compounds have diuretic and hypotensive actions. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

CHAPTER 6. 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 losartan. 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 losartan. 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

following drugs have been mentioned in the Pharmacopeia and other sources as being potentially applicable to losartan: Losartan •
Systemic - U.S. Brands: Cozaar http://www.nlm.nih.gov/medlineplus/druginfo/uspdi/202767.html
Losartan and Hydrochlorothiazide •
Systemic - U.S. Brands: Hyzaar http://www.nlm.nih.gov/medlineplus/druginfo/uspdi/203639.html
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.

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 losartan 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 losartan. 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 losartan. 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 “losartan”:

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 National Guideline Clearinghouse™ The National Guideline Clearinghouse™ offers hundreds of evidence-based clinical practice guidelines published in the United States and other countries. You can search this site located at http://www.guideline.gov/ by using the keyword “losartan” (or synonyms). The following was recently posted: •

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 losartan. 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: •

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 “losartan” (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 “losartan”. 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 option “Organization Resource Sheet.” Type “losartan” (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 “losartan” (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

LOSARTAN DICTIONARY The definitions below are derived from official public sources, including the National Institutes of Health [NIH] and the European Union [EU]. Abdomen: That portion of the body that lies between the thorax and the pelvis. [NIH] Abdominal: Having to do with the abdomen, which is the part of the body between the chest and the hips that contains the pancreas, stomach, intestines, liver, gallbladder, and other organs. [NIH] Abortion: 1. The premature expulsion from the uterus of the products of conception - of the embryo, or of a nonviable fetus. The four classic symptoms, usually present in each type of abortion, are uterine contractions, uterine haemorrhage, softening and dilatation of the cervix, and presentation or expulsion of all or part of the products of conception. 2. Premature stoppage of a natural or a pathological process. [EU] Acceptor: A substance which, while normally not oxidized by oxygen or reduced by hydrogen, can be oxidized or reduced in presence of a substance which is itself undergoing oxidation or reduction. [NIH] Acetylcholine: A neurotransmitter. Acetylcholine in vertebrates is the major transmitter at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system. It is generally not used as an administered drug because it is broken down very rapidly by cholinesterases, but it is useful in some ophthalmological applications. [NIH] Actin: Essential component of the cell skeleton. [NIH] Acute renal: A condition in which the kidneys suddenly stop working. In most cases, kidneys can recover from almost complete loss of function. [NIH] Adaptability: Ability to develop some form of tolerance to conditions extremely different from those under which a living organism evolved. [NIH] Adaptation: 1. The adjustment of an organism to its environment, or the process by which it enhances such fitness. 2. The normal ability of the eye to adjust itself to variations in the intensity of light; the adjustment to such variations. 3. The decline in the frequency of firing of a neuron, particularly of a receptor, under conditions of constant stimulation. 4. In dentistry, (a) the proper fitting of a denture, (b) the degree of proximity and interlocking of restorative material to a tooth preparation, (c) the exact adjustment of bands to teeth. 5. In microbiology, the adjustment of bacterial physiology to a new environment. [EU] Adduct: Complex formed when a carcinogen combines with DNA or a protein. [NIH] Adenocarcinoma: A malignant epithelial tumor with a glandular organization. [NIH] Adenosine: A nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter. [NIH] Administration, Oral: The giving of drugs, chemicals, or other substances by mouth. [NIH] Adolescence: The period of life beginning with the appearance of secondary sex characteristics and terminating with the cessation of somatic growth. The years usually referred to as adolescence lie between 13 and 18 years of age. [NIH] Adrenal Cortex: The outer layer of the adrenal gland. It secretes mineralocorticoids, androgens, and glucocorticoids. [NIH]
134
Losartan
Adrenal Glands: Paired glands situated in the retroperitoneal tissues at the superior pole of each kidney. [NIH] Adrenergic: Activated by, characteristic of, or secreting epinephrine or substances with similar activity; the term is applied to those nerve fibres that liberate norepinephrine at a synapse when a nerve impulse passes, i.e., the sympathetic fibres. [EU] Adrenergic beta-Antagonists: Drugs that bind to but do not activate beta-adrenergic receptors thereby blocking the actions of beta-adrenergic agonists. Adrenergic betaantagonists are used for treatment of hypertension, cardiac arrythmias, angina pectoris, glaucoma, migraine headaches, and anxiety. [NIH] Adverse Effect: An unwanted side effect of treatment. [NIH] Aerobic: In biochemistry, reactions that need oxygen to happen or happen when oxygen is present. [NIH] Aerosol: A solution of a drug which can be atomized into a fine mist for inhalation therapy. [EU]
Afferent: Concerned with the transmission of neural impulse toward the central part of the nervous system. [NIH] Affinity: 1. Inherent likeness or relationship. 2. A special attraction for a specific element, organ, or structure. 3. Chemical affinity; the force that binds atoms in molecules; the tendency of substances to combine by chemical reaction. 4.

[NIH] Clinical study: A research study in which patients receive treatment in a clinic or other medical facility. Reports of clinical studies can contain results for single patients (case reports) or many patients (case series or clinical trials). [NIH] Clinical trial: A research study that tests how well new medical treatments or other interventions work in people. Each study is designed to test new methods of screening, prevention, diagnosis, or treatment of a disease. [NIH] Cloning: The production of a number of genetically identical individuals; in genetic engineering, a process for the efficient replication of a great number of identical DNA molecules. [NIH] Clot Retraction: Retraction of a clot resulting from contraction of platelet pseudopods attached to fibrin strands that is dependent on the contractile protein thrombosthenin. Used as a measure of platelet function. [NIH] Coagulation: 1. The process of clot formation. 2. In colloid chemistry, the solidification of a sol into a gelatinous mass; an alteration of a disperse phase or of a dissolved solid which causes the separation of the system into a liquid phase and an insoluble mass called the clot or curd. Coagulation is usually irreversible. 3. In surgery, the disruption of tissue by physical means to form an amorphous residuum, as in electrocoagulation and photocoagulation. [EU] Codeine: An opioid analgesic related to morphine but with less potent analgesic properties and mild sedative effects. It also acts centrally to suppress cough. [NIH] Cofactor: A substance, microorganism or environmental factor that activates or enhances the action of another entity such as a disease-causing agent. [NIH] Collagen: A polypeptide substance comprising about one third of the total protein in mammalian organisms. It is the main constituent of skin, connective tissue, and the organic substance of bones and teeth. Different forms of collagen are produced in the body but all consist of three alpha-polypeptide chains arranged in a triple helix. Collagen is differentiated from other fibrous proteins, such as elastin, by the content of proline, hydroxyproline, and hydroxylysine; by the absence of tryptophan; and particularly by the high content of polar groups which are responsible for its swelling properties. [NIH] Collapse: 1. A state of extreme prostration and depression, with failure of circulation. 2. Abnormal falling in of the walls of any part of organ. [EU] Colloidal: Of the nature of a colloid. [EU] Colon: The long, coiled, tubelike organ that removes water from digested food.

Colorectal Cancer: Cancer that occurs in the colon (large intestine) or the rectum (the end of the large intestine). A number of digestive diseases may increase a person's risk of colorectal cancer, including polyposis and Zollinger-Ellison Syndrome. [NIH] Combination Therapy: Association of 3 drugs to treat AIDS (AZT + DDC or DDI + protease inhibitor). [NIH] Complement: A term originally used to refer to the heat-labile factor in serum that causes immune cytolysis, the lysis of antibody-coated cells, and now referring to the entire functionally related system comprising at least 20 distinct serum proteins that is the effector not only of immune cytolysis but also of other biologic functions. 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.

Vascular: Pertaining to blood vessels or indicative of a copious blood supply. [EU] Vasoactive: Exerting an effect upon the calibre of blood vessels. [EU] Vasoconstriction: Narrowing of the blood vessels without anatomic change, for which constriction, pathologic is used. [NIH] Vasodilation: Physiological dilation of the blood vessels without anatomic change. For dilation with anatomic change, dilatation, pathologic or aneurysm (or specific aneurysm) is used. [NIH] Vasodilator: An agent that widens blood vessels. [NIH] Vasopressor: 1. Stimulating contraction of the muscular tissue of the capillaries and arteries. 2. An agent that stimulates contraction of the muscular tissue of the capillaries and arteries. [EU]

[EU] Ventricle: One of the two pumping chambers of the heart. The right ventricle receives oxygen-poor blood from the right atrium and pumps it to the lungs through the pulmonary artery. The left ventricle receives oxygen-rich blood from the left atrium and pumps it to the body through the aorta. [NIH] Ventricular: Pertaining to a ventricle. [EU] Ventricular Dysfunction: A condition in which the ventricles of the heart exhibit a
Dictionary 189
decreased functionality. [NIH] Ventricular Function: The hemodynamic and electrophysiological action of the ventricles. [NIH]
Ventricular Remodeling: The geometric and structural changes that the ventricle undergoes, usually following myocardial infarction. It comprises expansion of the infarct and dilatation of the healthy ventricle segments. While most prevalent in the left ventricle, it can also occur in the right ventricle. [NIH] Venules: The minute vessels that collect blood from the capillary plexuses and join together to form veins. [NIH] Verapamil: A calcium channel blocker that is a class IV anti-arrhythmia agent. [NIH] Veterinary Medicine: The medical science concerned with the prevention, diagnosis, and treatment of diseases in animals. [NIH] Viral: Pertaining to, caused by, or of the nature of virus. [EU] Virulence: The degree of pathogenicity within a group or species of microorganisms or viruses as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host. [NIH] Virus: Submicroscopic organism that causes infectious disease. In cancer therapy, some viruses may be made into vaccines that help the body build an immune response to, and kill, tumor cells. [NIH] Vitreous: Glasslike or hyaline; often used alone to designate the vitreous body of the eye (corpus vitreum). [EU] Vitreous Hemorrhage: Hemorrhage into the vitreous body. [NIH] Vitro: Descriptive of an event or enzyme reaction under experimental investigation occurring outside a living organism. Parts of an organism or microorganism are used together with artificial substrates and/or conditions. [NIH] Vivo: Outside of or removed from the body of a living organism.
