β-lactam antibiotics have long been the mainstay for the treatment of bacterial infections. New Delhi metallo-β-lactamase 1 (NDM-1) is able to hydrolyze nearly all 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 comparison indicates the mechanisms of inhibition enhancement and provides insights for further inhibitor optimization.
β-内酰胺类抗生素一直是治疗细菌感染的主要药物。新德里金属β-内酰胺酶 1（NDM-1）能够水解几乎所有的β-内酰胺类抗生素，甚至包括临床上使用的丝氨酸β-内酰胺酶抑制剂。NDM-1 基因在致病菌中的广泛快速传播引起了广泛关注，因此迫切需要高效的 NDM-1 抑制剂。在这里，我们报告了一系列基于结构的 D-巯基脯氨酸衍生物的设计，这些衍生物可以在体外和细胞水平上抑制 NDM-1 的活性。结构比较表明了抑制增强的机制，并为进一步的抑制剂优化提供了思路。
