for having great structural diversity and bioactivities. In this study, two series of triazoles were synthesized. One was obtained by the 1,3-dipolar cycloaddition reaction between ethyl cyanoacetate and several phenyl azides forming 1H-1,2,3-triazoles and the other by rearrangement of Dimroth forming and 2H-1,2,3-triazoles. Both series were shown to be active against the epimastigote form of Trypanosoma
1,2,3-三唑杂环因其结构多样性和
生物活性而在药物
化学中脱颖而出。本研究合成了两个系列的三唑类化合物。一种是通过
氰基
乙酸乙酯和几种苯基
叠氮化物之间的 1,3-偶极环加成反应形成 1 H -
1,2,3-三唑,另一种是通过 Dimroth 形成和 2 H -
1,2,3-三唑的重排获得。两个系列均显示对克氏锥虫的上鞭毛体形式有活性。
1,2,3-三唑16d(SI 介于 100 和 200 之间)、17d和16f(SI > 200) 是活性最强的化合物,能够破坏作用于 CYP51 的锥鞭毛体的质膜并抑制
麦角甾醇的合成。候选16d在与 CYP51 相互作用时表现出最佳和最有利的特征。
