screened for in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv, compound 3u (MIC: 4.20μM) was found to be most active and are superior over existing standard drugs ciprofloxacin and ethambutol. Compounds 3c and 3x were found to equally potent as ethambutol. Among most potent compounds in the series, four compounds (3n, 3o, 3p and 3u) showed lower cytotoxicity which could be promising
已经开发了一种简便易行的方法,用于在无催化剂条件下使用容易获得的起始原料通过固态熔融反应合成官能化的吲唑。该转变涉及经由在热条件下获得的共轭腈中间体进行电环化。在针对结核分枝杆菌H37Rv的体外分枝杆菌活性筛选的化合物3a-3x中,对分子进行了进一步的抗结核活性筛选,发现化合物3u(MIC:4.20μM)活性最高,并且优于现有的标准药物环丙沙星和乙胺丁醇。发现化合物3c和3x与乙胺丁醇同样有效。在该系列中最有效的化合物中,有四个化合物(3n,3o,
