a series of mercaptoacyl amino acids and related compounds was synthesized and evaluated for inhibition of angiotensin-converting enzyme ( ace ) in order to determine the nature and importance of the putative interaction between ace and the amide moiety of inhibitors such as captopril ( 3-mercapto-2-methylpropanoyl-l-proline ) .
