(PZA) and ciprofloxacin (CPF) derivatives were conveniently synthesized and evaluated in vitro against H37Rv Mycobacterium tuberculosis (M. tb) strain. CPF derivative 16 displayed a modest activity (MIC = 16 µg/ml) and was docked into the M. tb DNA gyrase. Isoniazid‐pyrazinoic acid (INH‐POA) hybrid 21a showed the highest potency in our study (MIC = 2 µg/ml). It also retained its high activity against
方便地合成了几种合理设计的异烟肼(INH),吡嗪酰胺(PZA)和环丙沙星(CPF)衍生物,并在体外针对H37Rv结核分枝杆菌(M. tb)菌株进行了评估。CPF衍生物16表现出适度的活性(MIC = 16 µg / ml),并与M. tb DNA促旋酶对接。异烟肼-吡嗪酸(INH-POA)杂种21a在我们的研究中显示出最高的效价(MIC = 2 µg / ml)。它也保持其高活性对其他测试的结核分枝杆菌的药物敏感菌株(DS)V4207(MIC = 4微克/毫升)和对Vero细胞表现出可以忽略不计的细胞毒性(IC 50 ≥64微克/毫升)。四个经过测试的抗药性(DR)结核分枝杆菌与INH相似,这些菌株对21a难治,但对CPF敏感。化合物21A也是无活性的针对两个非结核性分枝杆菌(NTM)的菌株,表明其对选择性活性的结核分枝杆菌。21a对DS菌株的显着活性及其低细胞毒性突出了其治疗DS M.
