series of novel heteronuclear 5‐fluoroisatin dimers 4a–j tethered through ethylene were designed, synthesized, and examined for their in vitro anti‐mycobacterial activities against Mycobacterium tuberculosis H37Rv and multi‐drug resistant tuberculosis (MDR‐TB). All hybrids exhibited potential anti‐mycobacterial activities against the tested two strains with minimum inhibitory concentration (MIC) in a range

乙烯束缚了一系列新型的异核5-
氟异丁二聚体4a-j,并检查了它们对结核分枝杆菌H37Rv和耐多药结核病(MDR-TB)的体外抗分枝杆菌活性。所有杂种均表现出对测试的两个菌株的潜在抗分枝杆菌活性,最小抑菌浓度(MIC)在25至256μg/ mL的范围内。特别是,异核5-
氟异丁二聚体4a(MIC:25和32μg/ mL)对结核分枝杆菌的活性最高。 H37Rv和MDR-TB菌株对利于MDR-TB的效价分别比
利福平(MIC:64μg/ mL)和异烟
肼(MIC:> 128μg/ mL)高出三倍和四倍以上,值得进一步优化。
