Several aliphatic and aromatic lactones and two dimers were synthesized using the sequence: allylation - esterification - metathesis. These compounds were active in vitro against intracellular amastigotes of Leishmania panamensis. The structure-activity relationship showed the importance of the aliphatic side chain to enhance the biological activity and to obtain lower cytotoxicity. It was also observed that a decrease in the size of the lactone ring increases the selectivity index.
通过以下步骤合成了几种脂肪族和芳香族内酯及两个二聚体:烯丙基化 - 酯化 - 互变异构反应。这些化合物在体外对阔叶型利什曼原虫的细胞内阿马斯提戈特表现出活性。结构-活性关系显示脂肪族侧链对于增强
生物活性和降低细胞毒性的重要性。还观察到,内酯环尺寸的减少会提高选择性指数。
