Synthesis and kinetic testing of new inhibitors for a metallo-β-lactamase from Klebsiella pneumonia and Pseudomonas aeruginosa
摘要:
There are currently no clinically useful inhibitors against metallo-beta-lactamases (MBLs), enzymes that confer resistance against a broad spectrum of commonly used antibiotics and that are produced by an increasing number of bacterial pathogens. New pyrrole derivatives were synthesized and assayed for their inhibitory effect on the catalytic activity of the IMP-1 MBL from Pseudomonas aeruginosa and Klebsiella pneumoniae. Six compounds tested (3a-3c, 5, 7 and 8) show micromolar inhibition constants (K-i values range from similar to 10 to 30 mu M). In silico docking was employed to investigate the binding mode of the strongest inhibitor, 3b, in the active site of IMP-1. Implications for further improvements of binding efficiency and specificity are discussed. (C) 2011 Elsevier Masson SAS. All rights reserved.
