Chagas disease. Especially, inhibitors of the enzymatic activity of squalene synthase were shown to be effective compounds on T. cruzi proliferation in in vitro assays. In the present study we designed, synthesized and evaluated the effect of a number of isosteric analogues of WC-9 (4-phenoxyphenoxyethyl thiocyanate), a known squalene synthase inhibitor, on T. cruzi growth in tissue culture cells.

独占的细胞内寄生虫克氏锥虫是南美锥虫病或美洲锥虫病的病原体,锥虫病是美洲最流行的寄生虫病。目前控制这种疾病的化学疗法仍然是不足的,特别是在该疾病的慢性阶段。麦角固醇的生物合成途径作为查加斯病新药开发的分子靶标受到了广泛关注。特别是,在体外试验中,角鲨烯合酶的酶活性抑制剂被证明是有效的克氏锥虫增殖化合物。在本研究中,我们设计,合成和评估了WC-9的许多等规类似物的作用(4-苯氧基苯氧基乙基硫氰酸盐),一种已知的角鲨烯合酶抑制剂,对组织培养细胞中的克鲁氏锥虫生长。事实证明,含硒衍生物是克鲁维酵母生长的极强抑制剂。当然,出现了3-苯氧基苯氧基乙基,4-苯氧基苯氧基乙基,4-(3-氟苯氧基)苯氧基乙基,3-(3-氟苯氧基)苯氧基乙基硒氰酸酯和(±)-5-苯氧基-2-(硒代氰基甲基)-2,3-二氢苯并呋喃。该化合物家族的相关成员,表现出有效的ED 50值分别为0.084 µM,0.11 µM,0.083,µM,0
