N-Mercaptoalkanoyl derivatives of sulfur-containing amino acids were synthesized as candidate angiotensin I converting enzyme (ACE) inhibitors. Among them, N-[3-mercapto-2- (4-methoxybenzyl) propanoyl] -S-ethyl-L-cysteine (5d) was found to be the most potent inhibitor of ACE, with an IC50 value of 0.045μM. The maximum hypotensive effect of this compound was almost equal to that of captopril in anesthetized rats.
