  摘要：

  我们小组之前曾报道过几种表现出强效抗结核活性的吲哚甲酰胺。在这里，我们基于我们之前报道的同源模型和最近发表的分枝杆菌膜蛋白大 3 (MmpL3) 的晶体结构合理地设计了几种芳基甲酰胺。许多类似物对药物敏感 (DS)结核分枝杆菌( M. tb ) 菌株表现出相当大的抗结核活性。萘酰胺衍生物13c和13d是我们研究中最活跃的化合物（MIC：分别为 6.55、7.11 μM），显示出与一线抗结核（抗 TB）药物乙胺丁醇（MIC：4.89 μM）相当的效力。除了萘酰胺衍生物外，我们还确定了喹诺酮-2-甲酰胺和 4-芳基噻唑-2-甲酰胺作为潜在的 MmpL3 抑制剂，其中化合物8i和18b的 MIC 值分别为 9.97 和 9.82 μM。所有四种化合物都保留了对多重耐药 (MDR) 和广泛耐药 (XDR)结核分枝杆菌菌株的高活性。值得注意的是，两种活性最高的化合物13c和13d对 DS、MDR 和

It is worth noting that the two most active compounds 13c and 13d also exhibited the highest selective activity towards DS, MDR and XDR M. tb strains over mammalian cells [IC50 (Vero cells) ≥ 227 μM], indicating their potential lack of cytotoxicity.
