ABSTRACT
The preparation and characterization of a series of thiophenyl oxime phosphonate beta-lactamase inhibitors is described. A number of these analogs were potent and selective inhibitors of class C beta-lactamases from Pseudomonas aeruginosa and Enterobacter cloacae. Compounds 3b and 7 reduced the MIC of imipenem against an AmpC expressing strain of imipenem-resistant P. aeruginosa. A number of the title compounds retained micromolar potency against the class D OXA-40 beta-lactamase from Acinetobacter baumannii and at high concentrations compound 3b was shown to reduce the MIC of imipenem against a highly imipenem-resistant strain of A. baumanii expressing the OXA-40 beta-lactamase. In mice compound 3b exhibited phamacokinetics similar to imipenem.
