Background: Some compounds derived from Chinese medicine have demonstrated prospective roles in sensitization to chemotherapy. Aim: This study aimed to investigate Scutellaria barbata D.Don ethanol extract (SBEE) and its components on antitumor effects of low dose 5-fluorouracil against hepatocellular carcinoma cells. Methods: The antitumor effects of SBEE and its components, and their combinations with 5-FU were detected by 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium/phenazine methosulfate assay, and the effects of drug combinations were evaluated using Jin's formula. Results:SBEE and luteolin could inhibit tumor growth in time and dose dependent manners. Drug combination study showed that SBEE and luteolin could synergize the antitumor effects of 5-fluorouracil at different dose ratios against HepG2 and Bel-7402 cells.Conclusion: SBEE and luteolin showed synergistic antitumor effects when combined with low dose 5-FU, and the mechanism of the synergistic effect remains to be to be studied.
Keywords:5-Fluorouracil; luteolin;apoptosis
