  Substituted aryl malonamates as new serine β-lactamase substrates: Structure–activity studies

  摘要：

  A series of substituted aryl malonamates have been prepared. These compounds are analogues of aryl phenaceturates where the amido side chain has been replaced by a retro-amide. Like the phenaceturates, these compounds are substrates of typical class A and class C beta-lactamases, particularly of the latter, and of soluble DD-peptidases. The effect of substituents alpha to the ester carbonyl group on turnover by these enzymes is similar to that in the phenaceturates. On the other hand, N-alkylation of the side chain amide of malonamates, but not of phenaceturates, retains the susceptibility of the compounds to hydrolysis by beta-lactamases. This reactivity is not enhanced, however, by bridging the amide nitrogen and C alpha atoms. A phosphonate analogue of the malonamates was found to be an irreversible inhibitor of the beta-lactamases. These results, therefore, provide further evidence for the covalent access of compounds bearing retroamide side chains to the active sites of beta-lactam-recognizing enzymes. (C) 2009 Elsevier Ltd.
