A set of novel gatifloxacin-1H-1,2,3-triazole-isatin hybrids 6a-l was designed, synthesized and evaluated for their in vitro anti-mycobacterial activities against M. tuberculosis (MTB) H37Rv and MDR-TB as well as cytotoxicity. The results showed that all the targets (MIC: 0.025–3.12 μg/mL) exhibited excellent inhibitory activity against MTB H37Rv and MDR-TB, but were much more toxic (CC50: 7.8–62.5 μg/mL)
设计,合成和评估了一组新型加替沙星-1H-1,1,2,3-三唑-伊萨汀杂合体6a-1,它们对结核分枝杆菌(MTB)H 37 Rv和MDR-TB的体外抗分枝杆菌活性为:以及细胞毒性。结果表明,所有靶标(MIC:0.025–3.12μg/ mL)均对MTB H 37 Rv和MDR-TB表现出优异的抑制活性,但毒性比母体高(CC 50:7.8–62.5μg/ mL)。加替沙星(GTFX)(CC 50:125μg/ mL)。其中61种(MIC:0.025μg/ mL)在体外的效力是参考INH的2–32倍(MIC:0.05μg/ mL),GTFX(MIC:0.78μg / mL)和RIF(MIC:0.39μg / mL)对MTB H 37 Rv。活性最高的结合物6 k(MIC:0.06μg/ mL)对MDR-TB的效力是三个参考文献(MIC:1.0–> 128μg/ mL)的16-> 2048倍。两种混合动力汽车都需要进一步调查。
