In this paper, it is described the synthesis and the evaluation of the leishmanicidal activity of twenty-six eugenol derivatives bearing 1,2,3-triazole functionalities. The evaluation of the compounds on promastigotes of Leishmania amazonensis (WHOM/BR/75/Josefa) showed that eugenol derivatives present leishmanicidal activities with varying degrees of effectiveness. The most active compound, namely
在本文中,描述了具有1,2,3-三唑功能的26种丁香酚衍生物的合成和利什曼杀菌活性的评估。化合物对亚马逊利什曼原虫前鞭毛体的评估(WHOM / BR / 75 / Josefa)表明丁子香酚衍生物具有不同程度的杀菌作用。最具活性的化合物,即4-(3-(4-烯丙基-2-甲氧基苯氧基)丙基)-1-(4-甲基苄基)-1H-1,2,3-三唑(7k)(IC50 = 7.4±0.8μmol L-1),也靶向腹膜巨噬细胞内的利什曼原虫寄生虫(IC50 = 1.6μmolL-1),而不会干扰细胞生存力。7k对巨噬细胞的细胞毒性显示IC50为211.9μmolL-1,选择指数等于132.5。在相似的条件下,化合物7k比葡聚糖和喷他idine更有效,目前在诊所有两种药物。另外,理论计算表明,该化合物还具有口服药物预期范围内的大多数物理化学和药代动力学性质。相信具有1,2,3-三唑功能的丁香酚可能代表了一种支架,将被开发用于治疗利什曼病的新药物。
