compounds showed single digit micromolar or submicromolar NDM-1 inhibitory activities, which were much more potent than that of captopril. Among them, compounds 14a and 14m exhibited excellent NDM-1 inhibitory activities, with IC50 values of 0.10 and 0.12 μM, respectively. Further studies demonstrated that compound 14m displayed low cytotoxicity, good water solubility, high metabolic stability, and
表达对大多数β-内酰胺抗生素具有抗性的革兰氏阴性细菌的新德里金属-β-内酰胺酶1(NDM-1)的出现和全世界范围的流行对人类健康构成了严重威胁。但是,目前尚无NDM-1抑制剂在临床上得到批准。在此,基于先导化合物卡托普利,设计,合成了一系列化合物,并评估了其对NDM-1的抑制活性。所有设计的化合物均显示出一位数的微摩尔或亚微摩尔NDM-1抑制活性,远比卡托普利有效。其中,化合物14a和14m表现出优异的NDM-1抑制活性,IC50值分别为0.10和0.12μM。进一步的研究表明,化合物14m在小鼠中显示出低细胞毒性,良好的水溶性,高代谢稳定性和低急性毒性。
