the synthesis of new 2H-chromene or coumarin based acylhydrazones, which were evaluated for their in vitro antimycobacterial activity against reference strain Mycobacterium tuberculosis H37Rv and compared to the first-line antituberculosis drugs, isoniazid (INH) and ethambutol (EMB). The most active compounds 7m (MIC 0.13 μM), 7o (MIC 0.15 μM) and 7k (MIC 0.17 μM) demonstrated antimycobacterial activity
这项研究报告了新的基于2 H-色烯或香豆素的酰基hydr的合成,评估了它们对参考菌株结核分枝杆菌H37Rv的体外抗分枝杆菌活性,并与一线抗结核药物异烟肼(INH)和乙胺丁醇(EMB)进行了比较。活性最高的化合物7m(MIC 0.13μM),7o(MIC 0.15μM)和7k(MIC 0.17μM)在亚微摩尔浓度水平下表现出抗分枝杆菌活性,并且在人类胚胎肾细胞系HEK-293T中具有显着的相关细胞毒性。已经建立了这类化合物的构效关系。
