of β-lactam antibiotics with an inhibitor. So far, no clinically available inhibitors of metallo β-lactamases (MBLs) reported and the clinically inhibitors of serine β-lactamase are useless for MBLs. Accordingly, finding a potent inhibitor of the MBLs being very important. In this study, imidazole derivatives primarily were synthesized and their inhibitory activity were measured.

由于过度使用或滥用β-内酰胺类抗生素,细菌中的突变会导致抗生素耐药性。细菌可以对抗生素产生耐药性的一种策略是分泌金属β-内酰胺酶,该酶可以打开β-内酰胺抗生素的内酰胺环并使它们失活。这个问题对人类健康构成威胁,克服这种情况的一种策略是将β-内酰胺类抗生素与抑制剂并用。迄今为止,尚无关于金属β-内酰胺酶(MBL)的临床可用抑制剂的报道,而丝氨酸β-内酰胺酶的临床抑制剂对MBL毫无用处。因此,找到一种有效的MBL抑制剂非常重要。在这项研究中,主要合成了咪唑衍生物,并测定了它们的抑制活性。后来,计算机结合模型用于预测配体进入酶活性位点的构型和构象。用IC演示了两个分子针对MBL(IMP-1)的39 µM中的50和46 µM中的50。
