Phosphinic acid- and sulfoximine-based transition state analogues having a carboxyl group at the beta-carbon to the hetero atom exhibited significantly higher potency as mechanism-based inhibitors of E. coli gamma-glutamylcysteine synthetase as compared with L-buthionine-SR-sulfoximine. The enhanced inhibition potency is evidenced by both tight binding of the inhibitor and slow enzyme reactivation. Copyright (C) 1996 Elsevier Science Ltd
