All possible diastereoisomers of the dicarboxylic acid (10a), the biologically active form of imidapril (1), were synthesized, and their inhibitory activity against angiotensin converting enzyme (ACE) was examined. The in vitro ACE inhibitory activity of these compounds greatly depended on the configurations of the three asymmetric carbons in each molecule. The (S,S,S) isomer (10a) showed much more potent activity than the others.

(4S)-1-Alkyl-3-acyl>-2-oxoimidazolidine-4-carboxylic acid derivatives (3) were prepared by two methods.Their angiotensin converting enzyme (ACE) inhibitory activities and antihypertensive effects were evaluated, and the structure-activity relationships were discussed.The dicarboxylic acids 3a-n possessing S,S,S configuration showed potent in vitro ACE inhibitory activities with IC 50 values of 1.1x10-8-1.5x10-9 M.The most potent compound in this series, monoester 3p, had an ID 50 value of 0.24 mg/kg, po for inhibition of angiotensin I induced pressor response in normotensive rats and produced a dose-dependent decrease in systolic blood pressure of spontaneously hypertensive rats (SHRs) at doses of 1-10 mg/kg, po.
