for their potency against Mtb H37Rv. Designed molecules were synthesized by one-pot cycloaddition reaction in good to excellent yields. Anti-Tubercular evaluation of all synthesized derivatives identified 6k to be highly potent (MIC 1 μg/mL) against Mtb and drug-resistant strains. All potent derivatives were found to be non-toxic when tested against Vero cells. Also, in silico studies were employed to
摘要 设计、合成了一系列新的 3-苯基-4,5-二氢异恶唑-5-甲酰胺,并评估了它们对 Mtb H37Rv 的效力。设计的分子是通过一锅环加成反应合成的,产率很好。所有合成衍生物的抗结核评估确定 6k 对 Mtb 和耐药菌株具有高效(MIC 1 μg/mL)。当针对 Vero 细胞进行测试时,发现所有有效的衍生物都是无毒的。此外,还采用计算机模拟研究来探索设计化合物靶向分枝杆菌膜蛋白 Large-3 的结合模式。所有衍生物都表现出与受体的极好结合模式。优异的硅胶吸收、分布、代谢、
