With the aim to identify a potential drug candidate to treat cutaneous leishmaniasis, a series of 1-phthalazinyl hydrazones were synthesized and tested against Leishmania braziliensis parasite, one of the main responsible of this disease in the world. A structure-activity relationship permitted to identify two phthalazines containing nitroheterocyclic moiety 3l and 3m as promising new lead compounds
为了确定治疗皮肤利什曼病的潜在候选药物,合成了一系列1-酞嗪基并针对巴西利什曼原虫的寄生虫进行了测试,该寄生虫是世界上导致该病的主要病因之一。构效关系可以确定两种含氮杂环部分3l和3m的酞嗪为有前途的新型先导化合物。这些化合物显示出对前鞭毛体的形式的显著antileishmanial活性L. braziliensis,用EC 50倍在亚微摩尔和纳摩尔范围内的值。酞嗪3l还显示针对临床相关的胞内无鞭毛体形式的选择性和优良的活性,具有EC 50在亚微摩尔范围的值(0.59 μ M),在不影响宿主细胞的生存能力。氧化应激被确定为最具活性的酞嗪的可能作用方式。考虑到它们具有显着的抗菌活性和易于合成的特性,因此,对于硝基苯的合理设计,含有硝基杂环的酞嗪代表了一种有希望的抗巴西利什曼原虫的试剂。
