A series of quinoxaline 1,4-di-N-oxide derivatives variously substituted at C-2 position were synthesized and evaluated for in vitro antimycobacterial activity. Seventeen compounds exhibited potential activity (MIC 6.25mug/mL) against Mycobacterium tuberculosis (H37Rv), in particular the compounds 3d and 3j having an MIC value of 0.39mug/mL. None of the compounds exhibited cytotoxicity when using an
合成了一系列在C-2位置被不同取代的喹喔啉1,4-二-N-氧化物衍生物,并对其体外抗分枝杆菌活性进行了评估。十七种化合物对结核分枝杆菌(H37Rv)表现出潜在的活性(MIC 6.25mug / mL),特别是化合物3d和3j的MIC值为0.39mug / mL。在VERO细胞中使用MTT分析时,这些化合物均未显示出细胞毒性。为了进一步研究结构-活性关系,在抗分枝杆菌活性数据的基础上进行了CoMFA(q2 = 0.507,r2 = 0.923)和CoMSIA(q2 = 0.665,r2 = 0.977)模型。这些化合物的3D-QSAR研究可为进一步合理设计用于治疗结核病的新型喹喔啉1,4-二-N-氧化物提供有用的信息。
