identified mycolic acid methyl transferase (MmaA1) enzyme inhibitors as potential antitubercular agents using in silico modelling techniques. In continuation of that study, we synthesised a series of novel 3- (N-substituted glycinamido) benzoic acid derivatives with an aim to optimise the lead molecule. The newly synthesised compounds were evaluated for their in vitro antimycobacterial activity against M.
我们最近使用计算机模拟技术将霉菌酸甲基转移酶(MmaA1)酶抑制剂确定为潜在的抗结核药。在继续这项研究的过程中,我们合成了一系列新颖的3-(N-取代的甘氨酸酰胺基)苯甲酸衍生物,旨在优化铅分子。评价新合成的化合物对结核分枝杆菌H 37的体外抗分枝杆菌活性。收视率 其中,5种化合物A3,A4,A5,A6和A10表现出最强的活性,MIC值为1.6μg/ ml。进行了进一步的分子对接研究以研究配体与MmaA1蛋白的结合模式。对接研究显示,配体与MmaA1蛋白的催化位点残基TRP30,TYR 32,GLY 71,TRP 74,GLY 76,ALA 77和GLU 136产生强相互作用。还使用计算工具研究了化合物的药物似性和前导性性质。结果,在硅片和体外研究表明,这些新型化合物可用于治疗肺结核有利于引线。
