Abstract

Antimicrobial resistance among bacterial strains has emerged out to be a serious threat and contributes to the loss of effectiveness of the common antibiotics. New Delhi metallo-β-lactamase-1 (blaNDM-1) is an enzyme present in several pathogenic bacteria with a high incidence in and plays a crucial role in the development of antibacterial resistance. Mur enzymes are also important alternative drug targets in addition to blaNDM-1 which are crucial for the survival of the bacteria. is an aromatic medicinaltree with proven antibacterial properties. Fifteen compounds from were evaluated for their inhibitory effects on the target proteins blaNDM-1, Mur C, Mur E and Mur F of through molecular docking using the Glide (xp) module of Schrodinger. ADME toxicity was also predicted for all the fifteen compounds in the QikProp module. The docking results revealed that the compounds agnuside, negundoside and isoorientin showed promising inhibitory effects on all four targets blaNDM-1, Mur C, Mur E and Mur F of with docking scores greater than -7 kcal/mol and reasonable hydrogen bond interactions. The findings of this study provide a lead for developing novel drugs against potent multidrug-resistant .

摘要

细菌菌株中的抗菌耐药性已成为一个严重威胁,并导致常用抗生素失效。新德里金属β-内酰胺酶-1(blaNDM-1)是几种致病细菌中存在的一种酶,在印度发病率很高,在抗菌耐药性的发展中起关键作用。除blaNDM-1外,Mur酶也是重要的替代药物靶点,对细菌的生存至关重要。楝树是一种具有抗菌特性的芳香药用树。使用薛定谔的Glide(xp)模块通过分子对接评估了来自楝树的15种化合物对肺炎克雷伯菌的靶蛋白blaNDM-1、Mur C、Mur E和Mur F的抑制作用。还在QikProp模块中预测了所有15种化合物的ADME毒性。对接结果表明,化合物agnuside、negundoside和异荭草苷对肺炎克雷伯菌的所有四个靶点blaNDM-1、Mur C、Mur E和Mur F均显示出有前景的抑制作用,对接分数大于-7 kcal/mol,且有合理的氢键相互作用。本研究结果为开发针对强效多重耐药肺炎克雷伯菌的新型药物提供了线索。
