以藤黄酸为原料, 经过C-32位选择性环氧化、高碘酸氧化、甲基化、Jones氧化、不同条件的酯化、酰胺化等反应步骤, 合成了17个藤黄酸衍生物. 所有目标化合物的结构均通过核磁共振谱、红外光谱和质谱证实, 并采用MTT比色法对所合成的目标化合物进行了体外抗肿瘤细胞生物活性测试. 结果表明, 化合物5, 7, 8, 13对人肝癌细胞(HepG2)、人结肠癌细胞(HCT-116)的增殖抑制活性显著强于藤黄酸.

Seventeen new compounds were synthesized from gambogic acid (GA) with the structural modification of C-32. The reaction steps included selective epoxidation, periodate oxidation, methylation, Jones oxidation, different conditions of esterification, amidation, etc. The structures of target compounds were confirmed by NMR, IR and MS/ESI techniques. Their antitumor activities were evaluated in vitro by MTT assay. The results showed that compounds 5, 7, 8 and 13 were more potent than GA to human hepatoma cells (HepG2) and colon carcinoma cells (HCT-116).

Key words: gambogic acid, derivative, synthesis, antitumor, biological activity
