azides, thiocyanates, isothiouronium salts, and N,N′-diacetylisothioureas that were evaluated for their in vitro activity against replicating and non-replicating Mycobacterium tuberculosis (Mtb) H37Rv and toxicity to VERO cells. We found a selective group of new and promising compounds having good (micromolar) to excellent (sub-micromolar) potency against replicating Mtb H37Rv. Allylic thiocyanates bearing
结核病是全球急需新药的突发公共卫生事件。在此,我们报告了41种芳基烯丙基烯丙基叠氮化物,硫氰酸盐,异硫脲盐和N,N'-二乙酰基异硫脲的各种化合物的合成,这些化合物的抗复制和非复制性结核分枝杆菌(Mtb)H 37 Rv具有体外活性对VERO细胞有毒性。我们发现了一组新的有前途的化合物,它们具有良好的(微摩尔)至优异的(亚微摩尔)效力,可对抗复制的Mtb H 37收视率 带有卤代苯基(卤代= 2-Br,4-Br,4-Cl,4-F),4-甲基苯基和2-萘基的烯丙基硫氰酸酯是最有效的抗结核剂。特别地, 在VERO细胞毒性试验中,2-溴苯基取代的硫氰酸盐对复制的Mtb的MIC = 0.25μM,对非复制的Mtb的MIC = 8.0μM,IC 50 = 32μM。
