  Synthesis and biological evaluation of 6-bromo-6-substituted penicillanic acid derivatives as β-lactamase inhibitors

  摘要：

  The synthesis of a selected set of 6-bromopenicillanic acid derivatives with an additional C6 substituent is reported. All these substances were tested as inhibitors of class A and C beta-lactamase enzymes derived from Escherichia coli (TEM-1) and E. cloacae (P99). As 6-(1-hydroxyethyl) derivatives 4c and 6c were found to be weak beta-lactamase inhibitors, they were further investigated in combination with amoxicillin against a series of beta-lactamase-producing bacterial strains. Some structure-activity relationships are discussed. (C) 2002 Editions scientifiques et medicales Elsevier SAS. All rights reserved.
