Abstract

The synthesis of N-(3-mercaptopropionyl)-N-arylglycines (14a-x),- N-arylalanines (15a,b),-N-cycloalkylglycines (16a-k), and -1,2,3,4-tetrahydroisoquinoline-3-carboxylic acids (17a-d), -1,2,3,4-tetrahydroquinoline-2-carboxylic acids (18a-f), and -indoline-2-carboxylic acids (19a-k) is described. In vitro inhibition of angiotensin converting enzyme (ACE) is reported for each compound, and the structure--activity relationship for each series is discussed. The in vivo inhibition of ACE and antihypertensive effects of representative compounds from each series are discussed. The most potent compound, 19d, had an in vitro ACE IC50 of 2.6 X 10(-9) M and lowered blood pressure in spontaneous hypertensive rats 85 mm at a dose of 10 mg/kg po.
