A series of dibenzyl-γ-butyrolactones bearing a hydroxyl group at the benzylic position of 3-benzyl group were synthesized as hydrated analogue of isochaihulactone and evaluated against breast cancer human cell lines (MDA-M231, MCF-7 and T47D). The target compounds were synthesized in 7 steps from known lactone; (S)-(+)-γ-benzyloxymethyl-γ-butyrolactone. The key step was the aldol condensation between
合成了一系列在3-苄基的苄基位置带有羟基的二苄基-γ-丁内酯作为异二十烷酸内酯的水合类似物,并针对乳腺癌人细胞系(MDA-M231,MCF-7和T47D)进行了评估。从已知的内酯分7步合成目标化合物。(S)-(+)-γ-苄氧基甲基-γ-丁内酯。关键步骤是(+)-(R)-β-(苯并[ d]] [1,3]二氧杂-5-基甲基)-γ-丁内酯和取代的苯甲醛,得到相应的α-羟基苄基丁内酯类似物。合成化合物对乳腺癌人细胞系的细胞毒性研究表明,当浓度低于50μg/ mL时,其中一些化合物可抑制乳腺癌人细胞的增殖,其抑制百分率超过50%。
