In order to develop a lead antimycobacterium tuberculosis compound, a series of 52, novel pyrrole hydrazine derivatives have been synthesized and screened which target the essential enoyl-ACP reductase. The binding mode of the compounds at the active site of enoyl-ACP reductase was explored using surflex-docking method. The binding model suggests one or two hydrogen bonding interactions between pyrrole
为了开发抗结核分枝杆菌的先导化合物,已合成和筛选了一系列针对必需的烯酰-ACP还原酶的52种新颖的
吡咯肼衍
生物。采用表面对接法研究了化合物在烯酰-ACP还原酶活性位点的结合方式。结合模型表明
吡咯和InhA酶之间有一个或两个氢键相互作用。高活性化合物5r(MIC 0.2μg/ mL)显示与Tyr158和
NAD +的氢键相互作用以与
配体PT70和
三氯生相同的方式。就整体统计而言,通过数据库对齐生成的CoMFA和CoMSIA模型是最好的。CoMFA和CoMSIA模型的预测能力是使用13种化合物的测试集确定的,其预测相关系数(r pred 2)分别为0.896和0.930。
