BioAssay: AID 682760

Inhibition of recombinant Pseudomonas aeruginosa MBL IMP-1 using nitrocefin as substrate after 12 hrs by UV-spectrophotometric analysis

Bacterial resistance to beta-lactam antibiotics caused by class B metallo-beta-lactamases (MBL), especially for certain hospital-acquired, Gram-negative pathogens, poses a significant threat to public health. We report several 2-substituted 4,5-dihydrothiazole-4-carboxylic acids to be novel MBL inhibitors. Structure activity relationship (SAR) and molecular modeling studies were performed and implications for further inhibitor design are discussed. ..more
