In this study we demonstrate that carboxypeptidase A (CPA)-like enzyme is expressed in rat kidney. The major metabolites of angiotensin (Ang) I by the rat renal mesangial cell extract at 37 degrees C, pH 7.4, were Ang 1-9 and Ang II. Quinaprilat did not influence the formation of Ang 1-9, but it inhibited formation of Ang II. The formation of Ang 1-9 was(More)
Formation of metabolites from angiotensin I that passed the coronary vessels in the isolated working rat hearts of normal and streptozotocin-induced diabetes was evaluated. HPLC analysis showed that the levels of angiotensin II and angiotensin 1-7 were unaltered in the diabetic hearts, but the perfusates of the diabetic hearts contained smaller amounts of(More)
Angiotensin I-converting enzyme (ACE/kininase II) inhibitors potentiated guinea pig ileum's isotonic contractions to bradykinin (BK) and its analogues, shifting the BK dose-response curve to the left. ACE inhibitors added at the peak of the contraction immediately enhanced it further (343 +/- 40%), although the ileum inactivated BK slowly (t(1/2) = 12-16(More)
