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. (C) 2012 Elsevier Ltd. All rights reserved.
