Several N-thiophosphonyl-glutamates were found to be potent competitive inhibitors of a zinc-dependent glutamyl hydrolase, carboxypeptidase G (CPG). Weak inhibition exhibited by an analogous N-phosphonyl-glutamate suggests that the enhanced potency of the phosphonamidothioates is due to the presence of their sulfur ligand and its favorable interactions with active site features, presumably zinc(II).
