disease. METHODS Herein, the synthesis, antitrypanosomal and antimycobacterial activities of seventeen coumarinic N-acylhydrazonic derivatives have been reported. RESULTS These compounds were synthesized using methodology with reactions global yields ranging from 46%-70%. T. cruzi in vitro effects were evaluated against trypomastigote and amastigote, forming M. tuberculosis activity towards H37Rv sensitive
背景世界上近5-7百万人感染了克氏锥虫,每年约有10,000人死于与这种疾病相关的问题。方法本文报道了十七种香豆素N-酰基腙衍生物的合成、抗锥虫和抗分枝杆菌活性。结果这些化合物是使用方法合成的,反应的总产率为46%-70%。针对锥鞭毛体和无鞭毛体评估了 T. cruzi 体外效果,形成了对 H37Rv 敏感菌株和抗性菌株的结核分枝杆菌活性。针对 T. cruzi 的讨论,对于锥鞭毛体和无鞭毛体细胞内形式,活性更强的化合物仅显示中等活性 IC50/96h~20 μM。(E)-2-oxo-N'- (3,4, 5-三甲氧基苯亚甲基)-2H-chromene-3-carbohydrazide 在 INH 抗性/RIP 抗性菌株中显示出有意义的活性。结论这些作为多靶点的化合物可能是开发新的杀锥虫剂和杀菌剂的良好先导。
