title: beta-Lactam derivatives as enzyme inhibitors: N-substituted derivatives of (S)-4-oxoazetidine-2-carboxylate as inhibitors of elastase and papain.
abstract: N-Alkyl and N-acyl substituted 4-oxoazetidine-2-carboxylates are synthesized and evaluated as inhibitors of the proteases porcine pancreatic elastase (PPE) and papain. The compounds are obtained by alkylation or acylation at the nitrogen of benzyl (S)-4-oxoazetidine-2-carboxylate, which is synthesized by a modified literature procedure. The enzymatic assays prove some derivatives to be effective inhibitors of PPE and/or papain. The N-BOC protected amino acid derivatives 10 and 13 inhibit PPE reversibly with KI-values in the micromolar range. On the other hand, papain is inactivated irreversibly by benzyl (S)-2-(benzyloxycarbonyl)azetidin-1-acetate (6).
