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

N-dimethylformamide dimethyl acetal (DMF-DMA) for the selective cleavage of ethers via neighboring group participation. Various acid-labile functional groups, including carboxylate, allyl, tert-butyldimethylsilyl (TBS), and tert-butoxycarbonyl (Boc), suffer the conditions intact. The method offers an efficient approach to cleaving catechol monoalkyl ethers and to uncovering phenols from acetal-type protecting

intracellular T. cruzi, whereas they showed potent action against tachyzoites of T. gondii (ED50 values of 1.6 and 1.9 μM against T. gondii). In addition, analogues of WC‐9 in which the terminal aryl group is in the meta position with respect to the alkyl chain bearing the thiocyanate group showed potent inhibitory action against both T. cruzi and T. gondii at the very low micromolar range, which suggests
作为我们旨在寻找针对寄生虫病的新型安全化疗药物的项目的一部分,设计、合成了几种结构上与抗寄生虫药物 WC-9(4-苯氧基苯氧基乙基硫氰酸酯)相关的化合物,这些化合物在末端苯环上进行了修饰,并被评估为针对克氏锥虫(恰加斯病的病原体)和弓形虫(引起弓形体病的寄生虫)的生长抑制剂。大多数合成类似物表现出相似的抗寄生虫活性,并且比我们的先导 WC-9 稍强一些。例如,两种三氟甲基化衍生物针对细胞内克氏弓形虫表现出 10.0 和 9.2 μM的 ED 50值,而针对弓形虫速殖子表现出有效的作用(针对弓形虫的 ED 50值为 1.6 和 1.9 μM )。此外,末端芳基位于带有硫氰酸酯基团的烷基链间位的 WC-9 类似物在非常低的微摩尔范围内对克氏弓形虫和刚地弓形虫均表现出有效的抑制作用。表明对苯基取代模式对于生物活性来说不是必需的。
