11种香豆素类化合物对人膀胱癌细胞系E-J细胞株生长抑制活性的筛选

目的:从中草药中筛选有抗人膀胱癌活性的化合物、类药或先导化合物。方法:应用人膀胱癌细胞系E-J细胞株筛选11种香豆素类化合物对其生长的抑制活性。结果:伞形花内酯、滨蒿内酯、去甲基呋喃皮纳灵、异虎耳草素、羌活苷、二氢山芹醇当归酸酯、前胡素和甘草香豆素对人膀胱癌细胞系E-J细胞株增殖具有抑制作用,且呈浓度-效应关系;羌活苷、二氢山芹醇当归酸酯、前胡素和伞形花内酯效果更佳,其IC50分别为7.50×10-7、2.30×10-6、6.00×10-6和1.30×10-6mol/L。马栗树皮苷、花椒毒素和牛防风素在本实验条件下无效。结论:羌活苷、二氢山芹醇当归酸酯、前胡素和伞形花内酯是潜在的抗人膀胱癌化合物、类药或先导化合物。

Inhibitory effects of 11 coumarin compounds against growth of human bladder carcinoma cell line E-J in vitro

OBJECTIVE: To screen antitumor active compounds, drug-like or leading compounds from Chinese traditional and herbal drugs. METHODS: Eleven coumarin compounds isolated from the Chinese traditional and herbal drugs were studied for their antitumor activities in vitro by determining the inhibition rates against growth of human bladder carcinoma cell line E-J. RESULTS: It showed that umbelliferone, scoparone, demethylfuropinarine, isopimpinellin, forbesoside, columbianadin, decursin and glycycoumarin inhibited the growth of human bladder carcinoma cell line E-J in vitro and their activities showed a concentration-effect relationship. The inhibitory effects of forbesoside, columbianadin, decursin and umbelliferone, with IC50 values of 7.50x10(-7), 2.30x10(-6), 6.00x10(-6) and 1.30x10(-6) mol/L, respectively, were stronger than those of the other tested compounds. However, xanthotoxin, esculin and sphondin did not inhibit the growth of human bladder carcinoma cell line E-J in this assay condition. CONCLUSION: These findings indicate that forbesoside, columbianadin, esculin, decursin and umbelliferone would be effective or regarded as potent drug-like or leading compounds against human bladder carcinoma.
