PURPOSE Antitumor potential of angiotensin-converting enzyme inhibitors has been shown in different preclinical settings, which always involved immunocompromised organisms or nonimmunogenic tumor models. In our study, we wanted to evaluate the effect of captopril on growth of immunogenic tumors in immunocompetent animals. EXPERIMENTAL DESIGN We used different murine tumor models to evaluate t...

The effects of the orally active converting enzyme inhibitor, captopril (SQ 14225), on blood pressures and intakes and urine outputs of water and electrolytes were studied in rats with hereditary hypothalamic diabetes insipidus (Brattleboro strain) and in Long Evans rats (parent strain). Captopril given in the drinking water (30 mg day-1 kg-1) caused an increase in fluid intake and urine output...

Apresentamos um procedimento altamente seletivo e sensível para a determinação simultânea de captopril e de tioguanina baseado em processo de redissolução catódica adsortiva dos complexos de Cu(I)-captopril e de Cu(I)-tioguanina em um eletrodo gotejante de mercúrio. Captopril e tioguanina foram pré-concentrados na superfície da gota do eletrodo de mercúrio usando Cu(II) como sensor e tempo de a...

Rheumatoid arthritis (RA) is an inflammatory disease with autoimmune origin that affect joints firstly and then progress to be a systemic disease. Toll like receptor (TLR) play important role in the evolution progression of this Captopril angiotensin
 enzyme inhibitor (ACEI) widely used control elevation blood pressure. This drug has anti-inflammatory activities, for reason we try investig...

It has been reported that matrix metalloproteinase 9 (MMP-9) disrupts basement membrane and increases vascular permeability. MMP-9 therefore might participate in the pathogenesis of severe acute pancreatitis (SAP). Captopril, an angiotensin-converting enzyme inhibitor, could reduce MMP-9 expression. However, the effect of captopril on the outcome of SAP is not ascertained. The aim of this study...

The effect of enalapril and captopril on total glutathione content (GSSG + GSH) and selenium-dependent glutathione peroxidase (Se-GPx) and glutathione reductase (GSSG-Rd) activities was investigated in mouse tissues. CF-1 mice (4-mo-old females) received water containing enalapril (20 mg/l) or captopril (50 mg/l) for 11 wk. Enalapril increased GSSG + GSH content (P < 0.05) in erythrocytes (147%...

The effect of acute administration of captopril, an angiotensin converting enzyme inhibitor, on vascular responses of rings of rat aortic smooth muscle was tested in vitro. Dose-response curves for various vasoactive agents were obtained before and after exposure to captopril (2 x 10(-4) M) for 30 minutes. In the presence of captopril, contractile responses to angiotensin I (5 x 10(-10) to 5 x ...

The acute effect of the orally-active converting enzyme inhibitor, captopril, was compared to that of saralasin in 13 patients with various forms of hypertension on ad libitum sodium intake. A significant difference between the effects of the two drugs on mean arterial pressure (MAP) was found (-11 +/- 3 mm Hg with saralasin, -24 +/- 4.5 mm Hg after captopril). This difference was not correlate...

Captopril infused into the lateral ventricle (ICV) of adult spontaneously hypertensive rats (SHR) decreases blood pressure. The current study was designed to explore the effects of brain converting-enzyme inhibition in young animals before the development of established hypertension and to characterize changes induced by captopril in a variety of pressor systems that might be responsible for th...

A patient with a phaeochromocytoma and severe left ventricular heart failure caused by a catecholamine-induced cardiomyopathy is described. The clinical signs of congestive heart failure resolved rapidly on treatment with captopril and myocardial performance became normal within two weeks of medical treatment with captopril for one week and with captopril in combination with phenoxybenzamine fo...
