alpha -Ketohydroxamates were synthesized as bioisosteres of alpha -ketoamides. The alpha -ketohydroxamates were generally more potent than the corresponding alpha -ketoamides. The potency of the compounds suggests that hydrogen bonding and steric bulk of substituents on the nitrogen atom of the ketoamide moiety influence calpain inhibition. (C) 2001 Elsevier Science Ltd.
