3-triazoles demonstrated significant trypanocidal activity against T. cruzi. In this paper, we synthesized a new series of 92 examples of 1,2,3-triazoles. Six compounds exhibited antiparasitic activity, 14, 25, 27, 31 and 40, 43 and were effective against epimastigotes of two strains of T. cruzi (Y and Dm28-C) and 25, 27 and 31 exhibited trypanocidal activity similar to benzonidazole. Notably, the compound
南美锥虫病是鞭毛原生动物克氏锥虫引起的拉丁美洲最相关的地方病之一。硝呋替莫和苯甲唑是用于治疗该疾病的药物,但它们通常具有毒性,并具有严重的副作用。没有附带影响的新的有效分子,促进了研究的发展,以开发新的先导化合物,并将其推进临床试验。以前,基于3-硝基-1H-1,2,4-三唑的胺和1,2,3-三唑显示出了对克鲁氏锥虫的显着的锥虫杀灭活性。在本文中,我们合成了92个1,2,3-三唑的新系列。六种化合物分别显示出14、25、27、31和40、43的抗寄生虫活性,并且对两种克氏锥虫(Y和Dm28-C)和25,图27和31显示出与苯甲唑类似的锥虫杀灭活性。值得注意的是,与苯甲唑相比,化合物25增加了对克鲁维氏锥虫的毒性,而对小鼠巨噬细胞或原代小鼠腹膜巨噬细胞的细胞系没有明显的毒性。结果,我们计算了两个克鲁氏梭菌菌株的选择性指数,最高分别为2000至25和31。衍生物14引起锥虫作用,因为它没有破坏
