caused by mycobacterium tuberculosis (Mtb), responsible for the utmost number of deaths annually across the world. Herein, twenty-one new substituted 1,2,4-oxadiazol-3-ylmethyl-piperazin-1-yl-quinoline derivatives were designed and synthesized through multistep synthesis followed by in vitro evaluation of their antitubercular potential against Mtb WT H37Rv. The compound QD-18 was found to be promising
结核病是由结核分枝杆菌(Mtb)引起的传染病,它是全世界每年死亡人数最多的原因。在此,设计和合成了二十一种新的取代的1,2,4-恶二唑-3-基甲基-哌嗪-1-基-喹啉衍生物,并通过多步合成,然后对其抗Mtb WT H37Rv的抗结核潜力进行了体外评估。发现化合物QD-18的MIC值为0.5 µg / ml很有前景,而QD-19至QD-21的MIC值为0.25 µg / ml也很引人注目。此外,我们进行了实验,以确认这些化合物的代谢稳定性,细胞毒性和药代动力学,以及对它们的杀灭动力学。QD-18。发现这些化合物是口服生物利用的并且是高度有效的。总而言之,这些结果表明QD-18,QD-19,QD-20和QD-21是用于开发新型化学类抗结核药物的有前途的先导化合物。
