essential for the viability of M. tuberculosis and has been a promising therapeutic target for new anti-TB agents. Herein, we report the discovery of pyridine-2-methylamine antitubercular compounds using a structure-based drug design strategy. Compound 62 stands out as the most potent compound with high activity against M. tb strain H37Rv (MIC = 0.016 μg/mL) as well as the clinically isolated strains
分枝杆菌膜蛋白大 3 (MmpL3) 是一种内膜蛋白,在分枝杆菌酸的运输中发挥着至关重要的作用,而分枝杆菌酸对于结核分枝杆菌的生存至关重要,并且一直是新型抗结核药物的有前景的治疗靶点。在此,我们报告使用基于结构的药物设计策略发现了吡啶-2-甲胺抗结核化合物。化合物62是最有效的化合物,对支原体具有高活性。 tb 菌株 H37Rv (MIC = 0.016 μg/mL) 以及临床分离的 MDR/XDR-TB 菌株 (MIC = 0.0039–0.0625 μg/mL),Vero 细胞毒性低 (IC 50 ≥ 16 μg /mL),中等肝微粒体稳定性(CL int = 28 μL/min/mg)。此外,由于mmpL3中的单核苷酸多态性,S288T的抗性突变体对吡啶-2-甲胺62具有抗性,这表明化合物62可能是MmpL3的靶标。
