for developing antitubercular drugs. Based on the X-ray crystal structure of MmpL3 inhibitor complexes, a series of novel 1,2,4-triazole derivatives were designed, synthesized and evaluated antitubercular activity against Mtb strain H37Rv. Comprehensive structure–activity relationship exploration resulted in the identification of compounds 21 and 28, which possess potent antitubercular activity against
抑制分枝杆菌膜蛋白大3(MmpL3)从而影响分枝菌酸生物合成途径已被证明是开发抗结核药物的有效策略。基于MmpL3抑制剂复合物的X射线晶体结构,设计、合成了一系列新型1,2,4-三唑衍生物,并评估了其对Mtb菌株H37Rv的抗结核活性。全面的构效关系探索鉴定出化合物21和28,它们对Mtb菌株 H37Rv [最低抑菌浓度 (MIC) = 0.03–0.13 μg/mL] 和多重耐药 (MDR) 临床分离株具有有效的抗结核活性和广泛耐药 (XDR) 结核病 (MIC = 0.06–1.0 μg/mL)。此外,根据计算机吸收、分布、代谢和排泄 (ADME) 预测,化合物21和28对哺乳动物 Vero 细胞显示出可忽略的细胞毒性 (IC 50 ≥ 32 μg/mL) 和良好的理化和药代动力学特性。最后,使用微量热泳 (MST) 测定将代表性 1,2,4-三唑28的潜在靶标确定为 MmpL3。
