The emergence and spread of antibiotic‐resistant pathogens is a global public health problem. Metallo‐β‐lactamases (MβLs) such as New Delhi MβL‐1 (NDM‐1) are principle contributors to the emergence of resistance because of their ability to hydrolyze almost all known β‐lactam antibiotics including penicillins, cephalosporins, and carbapenems. A clinical inhibitor of MBLs has not yet been found. In this
抗生素抗性病原体的出现和传播是全球性的公共卫生问题。金属β-内酰胺酶(MβLs)(例如新德里MβL-1(NDM-1))是产生抗药性的主要因素,因为它们能够水解几乎所有已知的β-内酰胺抗生素,包括青霉素,头孢菌素和碳青霉烯。尚未发现MBL的临床抑制剂。在这项研究中,我们开发18新的二芳基取代的azolylthioacetamides,发现它们全部是从MβLL1的抑制剂嗜麦芽(ķ我<2μ中号),13为NDM-1(混合抑制剂ķ我<7μ中号),以及四个为从测试MβLs资料库的所有四个的广谱抑制剂脆弱拟杆菌,NDM-1和管理系统从气单胞菌维罗纳,和L1(ķ我<52μ中号),它们是代表菌素B1a,B1b矮秆基因,B2的,和B3子类。对接研究表明,具有最强抑制活性的偶氮基硫代乙酰胺优先通过三唑部分与Zn II离子配位,而其他部分则主要与保守的活性位点残基Lys224(CcrA,NDM-1和ImiS)相互作用。
