摘要
以藤黄酸为原料,与相应的二溴烷烃反应得到藤黄酸溴代烷基酯,再将其与不同的胺反应得到20个藤黄酸胺基醇酯衍生物(3a^3t),其结构经IR、MS、1H NMR确证。采用MTT法测试目标化合物对肝癌细胞Bel-7402、SMMC-7721、Bel-7404、QGY-7701和HepG2的体外抗肿瘤活性。结果显示,大多数化合物表现出较强的抗肿瘤活性,其中化合物3c,3g,3h,3p和3t活性强于藤黄酸,3g和3h的抗肿瘤活性强于紫杉醇。
Gambogic acid（GA）was treated with corresponding dibromoalkanes to form brominated compounds, which were coupled with various amines to generate the target compounds 3a-3t. Their structures were characterized by IR, MS and 1H NMR. The effects of the target compounds on the proliferation of human HCC Bel-7402, SMMC-7721, Bel-7404, QGY-7701 and HepG2 cells were evaluated in vitro by MTT assay using GA and taxol as positive controls. Most of the GA derivatives（3c, 3g, 3h, 3p, 3t）displayed more potent activity against liver cancer cells than GA, and the activities of 3g and 3h were even more potent than that of taxol.
