摘要 本文考察了芫菁体内结合斑蝥素和人工合成的斑蝥素盐类衍生物斑蝥素酸镁的体外抗肿瘤活性。采用WST-1法检测两者在体外对人胃腺癌SGC-7901细胞增殖的抑制作用。实验结果显示两者对SGC-7901细胞均表现出明显的抑制效果,且随药物浓度升高其抑制作用增强,呈剂量效应关系;其半数抑制浓度(IC50)分别为10.86和8.65μmol/L。此外,通过流式细胞术检测表明,结合斑蝥素能引起SGC-7901细胞G0~G1期阻滞;斑蝥素酸镁则引起SGC-7901细胞S期阻滞,两者均能通过干预SGC-7901细胞的周期来抑制其增殖。 The study inversitigated the anti-tumor activity of bound cantharidin extacted from meloids Mylabris cichorii and magnesium cantharidate obtained by chemosynthesis in vitro. WST-1 colorimetry was used to evaluate the inhibitory effect of bound cantharidin and magnesium cantharidate on human gastric cancer cell line SGC-7901. The results showed they displayed obvious inhibitory effect on the growth of SGC-7901 cells in a dose-dependent manner, and the IC50 value were 10.86 and 8.65 μmol/L,respectively. Moreover,the results of flow cytometer showed that the G0-G1 phase was ar- rested by bound cantharidin,while S phase was arrested by magnesium cantharidate. They could inhibit proliferation on SGC-7901 cells by cell cycle disturbing.
