The angiotensin converting enzyme inhibitor captopril prevents myosin-induced experimental autoimmune myocarditis. Captopril inhibits production of angiotensin II and increases bradykinin signaling, among other actions. To test whether captopril inhibits disease through blockade of angiotensin signaling, we tested the ability of losartan, an angiotensin II receptor blocker, to prevent myosin-in...
There is substantial evidence suggesting that angiotensin II plays an important role in elevating blood pressure of spontaneously hypertensive rats, despite normal plasma renin activity, and that converting enzyme inhibitors (captopril) can effectively normalize blood pressure in the spontaneously hypertensive rats. One mechanism by which angiotensin II induces hypertension is via oxidative str...
Low density lipoprotein (LDL) was incubated with 20 microM of the angiotensin converting enzyme (ACE) inhibitors captopril, fosinopril and quinapril or ethanol. Oxidation of LDL was initiated by addition of CuSO4 and monitored for production of conjugated dienes, thiobarbituric acid reactive substances (TBARS) and lipid peroxides. The inhibition of production of conjugated dienes was expressed ...
Treatment with captopril has proved effective in some patients with resistant heart failure. Since cardiac output responses to captopril treatment are generally small, we infused the positive inotropic agent dobutamine in six patients already receiving captopril to determine whether cardiac output could be augmented without concomitantly increasing myocardial oxygen demands. At low infusion rat...
Hypertension is one of the most common chronic diseases affecting millions people worldwide. The structure-based drug design targeting domains ACE important in treatment hypertension. domain specificity inhibition somatic and testicular by tripeptide GVR binding to specified active site has not been previously described. From this study, it was shown that significantly bound C-domain as compare...
a new series of alkylthio imidazole analogues of captopril, an ace inhibitor used in the treatment of hypertension, was designed and synthesized in order to obtain agents more active than captopril with less side effects. all the compounds thus prepared were purified and characterized by ir, nmr and mass analytical instruments.
We investigated the role of circulating ANG II in sodium appetite after adrenalectomy. Adrenalectomized rats deprived of their main access to sodium (0.3 M NaCl) for 9 h drank 14.1 +/- 1.5 ml of the concentrated saline solution in 2 h of access. Intravenous infusion of captopril (2.5 mg/h) during the last 5 h of sodium restriction reduced sodium intake by 77 +/- 12% (n = 5) without affecting th...
To THE EDITOR: Since captopril, the first orally active angiotensin converting enzyme inhibitor, was introduced into clinical medicine, this new approach to blocking the formation of angiotensin II and lowering the blood pressure, appears to be tolerated well in most hypertensive patients. However, during a randomized trial comparing the antihypertensive efficacy of captopril, 25 mg b.i.d., wit...
Rats rendered hypothyroid by treatment with methimazole develop an exaggerated sodium appetite. We investigated here the capacity of hypothyroid rats (N = 12 for each group) to respond to a low dose of captopril added to the ration, a paradigm which induces an increase in angiotensin II synthesis in cerebral areas that regulate sodium appetite by increasing the availability of circulating angio...
1. The role of endogenous prostaglandins in the antihypertensive mechanism of the angiotensin converting enzyme inhibitor, captopril, was investigated. 2. An unequivocal reduction in blood pressure and significant increase in plasma renin activity and urinary prostaglandin E excretion were found after the captopril administration. 3. The changes in blood pressure, plasma renin activity and urin...
