The development of hybrid compounds containing limonene- and recognized anti-T. cruzi-heterocycleframeworks is described. The six new compounds displayed broad antitrypanosomal activities having 5-nitrofuran and 5- nitroindazole derivatives, the best profiles. In addition, a 5-nitroindazole derivative evaluated against a panel of fungi exhibited relevant activities. Knowing that free-radical-production operates as one of the mechanisms of action on these heterocycles, we studied a potential extra-mechanism, membrane-sterols changes. Non-relevant T. cruzi squalene accumulation was observed for any of the tested hybrid-limonene derivatives.
含有柠檬烯和公认的抗 T 的杂化化合物的开发。描述了 cruzi-heterocycleframeworks。这六种新化合物表现出广泛的抗锥虫活性,其中 5-硝基呋喃和 5-硝基吲唑衍生物表现最好。此外,对一组真菌进行评估的 5-硝基吲唑衍生物表现出相关活性。知道自由基产生是这些杂环化合物的作用机制之一,我们研究了一种潜在的额外机制,即膜甾醇的变化。对于任何测试的混合柠檬烯衍生物都观察到非相关的克氏锥虫角鲨烯积累。

The synthesis and in vitro activity of R(+)-Limonene derivatives against Leishmania and Trypanosoma cruzi strains are reported. Seven compounds have shown better in vitro activity against Leishmania (V.)braziliensis than the standard drug pentamidine. Additionally, we have identified two promising new anti-T. cruzi limonenederivatives.
