摘要
利用Mn(Ⅱ)/Co(Ⅱ)/PhP(O)HOR/O2新催化体系合成了一系列新型脱碳木脂素类化合物(2a~2g),并采用MTT比色实验法,研究了所合成化合物体外抗肿瘤抑制活性.分别对人乳腺癌细胞(MCF-7),人肝癌细胞(Bel-7402),人肺癌(A549)和人子宫颈癌细胞(Hela)进行检测.结果表明:化合物2a~2g对4种癌细胞均有较强的抑制作用,尤其是对人肝癌细胞Bel-7402的抑制效果明显,其中化合物2b显示出比相同条件下紫杉醇更好地抗癌抑制活性(IC50:18.9μg/mL),说明所合成的芳基烯二聚化合物2b具有更好的应用前景。
In this study, we have synthesized a series of new norlignan compounds 2a-2g and evalua- ted their anticancer activities with MTT assay by using human hepaioma Bel-7402 cells, human breast ade- nocarcinoma MCF-7 cells, human lung carcinoma A549 cells and human cervical carcinoma HeLa cells. It has been shown that the products (2a-2g) exhibit higher cytotoxicity to cells, and especially, product 2b treated with Bel-7402 cells shows a lower cytotoxicity (IC50:18.9μg/mL) than free paclitaxel.
