New anti-tubercular agents, imidazo[1,2-a]pyridine-2-carboxamide derivatives (5a–q) have been designed and synthesized. The structural considerations of the designed molecules were further supported by the docking study with a long-chain enoyl-acyl carrier protein reductase (InhA). The chemical structures of the new compounds were characterized by IR, 1H NMR, 13C NMR, HRMS and elemental analysis. In
已经设计并合成了新的抗结核药,咪唑并[1,2-a]吡啶-2-羧酰胺衍生物(5a – q)。设计分子的结构考虑因素进一步得到了与长链烯酰基-酰基载体蛋白还原酶(InhA)的对接研究的支持。通过IR,1 H NMR,13 C NMR,HRMS和元素分析对新化合物的化学结构进行了表征。另外,还已经记录了化合物5f的单晶X射线衍射。在体外评估了化合物对结核分枝杆菌H37Rv的抵抗力以及对HEK-293T细胞系的细胞毒性。在测试的化合物中5j,5l和5q成为具有低细胞毒性的良好抗结核药。通过分子对接解释了这些衍生物的结构与抗结核活性的关系。
