Abstract As part of the search for anti-trypanosomal agents, this work presents the production of sixteen derivatives. All of them were obtained from two natural diterpenes, one with kaurane skeleton (ent-kaurenoic acid) and other with a pimarane skeleton (ent-pimaradienoic acid). Then, the eighteen compounds were assayed against epimastigote form of Trypanosoma cruzi, with the derivatives showing increase
摘要 作为寻找抗锥虫剂的一部分,这项工作介绍了十六种衍生物的生产。它们都是从两种天然二萜中获得的,一种具有贝壳杉骨架(ent -kaurenoic acid),另一种具有海松骨架(ent -pimaradienoic acid)。然后,对 18 种化合物针对克氏锥虫的上鞭毛体形式进行了分析,其衍生物显示出与其前体相关的活性增加。此外,最活跃的衍生物的 IC 50 <12.5 µM(估计为 0.8 µM),低于用作对照的苯硝唑 (IC 50 = 9.8 µM)。酸二萜的酯化被证明是寻找抗锥虫剂的有趣方式。
