β-lactam antibiotics and even clinically used serine-β-lactamase inhibitors. The wide and rapid spreading of NDM-1 gene among pathogenic bacteria has attracted extensive attention, therefore high potency NDM-1 inhibitors are urgently needed. Here we report a series of structure-guided design of D-captopril derivatives that can inhibit the activity of NDM-1 in vitro and at cellular levels. Structural
长期以来,β-内酰胺类抗生素一直是治疗细菌感染的主要手段。新德里金属β-内酰胺酶1(NDM-1)能够水解几乎所有β-内酰胺抗生素,甚至可以水解临床上使用的丝氨酸-β-内酰胺酶抑制剂。NDM-1基因在致病细菌中的广泛和快速传播引起了广泛的关注,因此迫切需要高效的NDM-1抑制剂。在这里我们报告一系列的D-卡托普利衍生物的结构指导设计,可以在体外和细胞水平抑制NDM-1的活性。结构比较表明了抑制作用增强的机制,并为进一步的抑制剂优化提供了见识。
