由B类金属β-内酰胺酶(MBL)引起的细菌对β-内酰胺抗生素的耐药性,特别是对于某些医院获得性革兰氏阴性病原体,对公共卫生构成重大威胁。我们报道了几种2-取代的4,5-二氢噻唑-4-羧酸类化合物作为新型MBL抑制剂。构效关系(SAR)和分子模拟研究进行了进一步的抑制剂设计的影响进行了讨论。
Bacterial resistance to β-lactam antibiotics caused by class B metallo-β-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.
