2-Ethyl-2-methyl-3-mercaptopropanoic acid (6) and 2-benzyl-2-methyl-3-mercaptopropanoic acid (7) were synthesized and evaluated as inhibitors for carboxypeptidase A (CPA), a prototypical zinc protease with the expectation that the binding affinities of these inhibitors would be augmented over those of 2-ethyl-3-methylsuccinic acid (2) and 2-benzyl-3-methylsuccinic acid (3), respectively, in light of the fact that the sulfhydryl group is a better zinc coordinating moiety than the carboxylate group. Contrary to the expectation, however, the inhibitory potency of 6 was not improved and that of 7 was rather attenuated by the replacement. A probable explanation for the unexpected results is offered.
