The cryptolactones A1, A2, B1, and B2 isolated from a Cryptomyzus sp. aphid were synthesized via the Mukaiyama aldol reaction and olefin metathesis. Their antipodes and derivatives were also synthesized by the same strategy to investigate structure–activity relationships. These compounds exhibited cytotoxic activity against human promyelocytic leukemia HL-60 cells with IC50 values of 2.1–42 µM.
通过 Mukaiyama 醛醇反应和烯烃复分解反应合成了从隐翅虫蚜虫中分离出来的隐内酯 A1、A2、B1 和 B2。为了研究结构-活性关系,我们还采用相同的策略合成了它们的对位化合物和衍
生物。这些化合物对人类早幼粒细胞白血病 HL-60 细胞具有细胞毒性活性,IC50 值为 2.1-42 µM。
