As a part of our project pointed at the search of new safe chemotherapeutic and chemoprophylactic agents against parasitic diseases, several compounds structurally related to 4-phenoxyphenoxyethyl thiocyanate (WC-9), which were modified at the terminal aromatic ring, were designed, synthesized and evaluated as antiproliferative agents against Trypanosoma cruzi, the parasite responsible of American
作为我们项目的一部分,旨在寻找针对寄生虫病的新型安全化学治疗剂和化学预防剂,我们设计、合成了几种与 4-苯氧基苯氧基乙基硫氰酸酯 ( WC - 9 )结构相关的化合物,这些化合物在末端芳环上进行了修饰。被评估为抗克氏锥虫的抗增殖剂,克氏锥虫是导致美洲锥虫病(南美锥虫病)和弓形虫,弓形虫病的病原体的寄生虫。大多数合成类似物表现出类似的抗寄生虫活性,比参考化合物WC - 9更有效。例如,硝基衍生物13显示5.2 μM的 ED 50值。有趣的是,WC - 9的区域异构体化合物36显示出与WC - 9相似的抑制作用,表明对苯基取代模式不一定是生物活性所必需的。针对弓形虫的生物学评价也非常有希望。该ED 50个对应于值13,36和37是在对的速殖子的非常低的微摩尔水平弓形虫。
