氧化苦参碱黄芩苷组合物对HepG2.2.2.15细胞乙肝病毒抗原表达的抑制作用

目的研究氧化苦参碱黄芩苷组合物对HepG2.2.2.15细胞乙型肝炎病毒抗原表达的影响。方法培养HepG 2.2.2.15细胞并在使用药物处理细胞之后,采用四甲基偶氮唑蓝(MTT)比色分析法检测药物对细胞的毒性作用,采用酶联免疫吸附试验(ELISA)检测药物对细胞向培养上清液中分泌HBsAg、HBeAg的抑制作用。结果氧化苦参碱在0.125~1 g.L-1浓度范围内,对HepG 2.2.2.15细胞毒性较小,而2 g.L-1和4 g.L-1的剂量对细胞毒性较大;氧化苦参碱对HBsAg和HBeAg的抑制作用,在0.125~1 g.L-1剂量范围内逐渐增加。黄芩苷在0.625~2 g.L-1浓度范围内,对细胞的毒性作用逐渐增加;黄芩苷对HBsAg和HBeAg的抑制作用,在0.625~1 g.L-1剂量范围内逐渐增加,但是抑制效果明显弱于氧化苦参碱。氧化苦参碱黄芩苷组合物(A~F组)对HepG2.2.2.15细胞株分泌乙肝病毒抗原具有良好的抑制作用,而且对HBeAg的抑制效果优于HBsAg。其中C组氧化苦参碱黄芩苷组合物对乙肝病毒抗原分泌抑制作用优于单独使用氧化苦参碱(HBsAg:P=0.043;HBeAg:P=0.026)。结论氧化苦参碱黄芩苷组合物对HepG 2.2.2.15细胞株分泌乙肝病毒抗原有良好的协同抑制作用。

The inhibitory effect of oxymatrine-baicailin compound on hepatitis B viral antigens secretion in HepG2.2.2.15 cells

Aim To study the inhibitory effect of Oxymatrine-Baicailin compound on the secretion of hepatitis B viral antigens in HepG 2.2.2.15 cells.Methods HepG2.2.2.15 cells were cultured and treated with a series of Oxymatrine,Baicailin,or Oxymatrine-Baicailin compound respectively.The toxicity effect was determined by MTT colorimetry.Con-tents of the hepatitis surface antigen(HBsAg) and hepatitis e antigen(HBeAg) in the culture supernatants were determined by Enzyme linked immunosorbent assay.Results Oxymatrine at concentrations between 0.125 and 1 g·L~(-1) had little toxicity effect on cells,but Oxymatrine at 2 g·L~(-1) and 4 g·L~(-1) had much more toxicity effect on cells.The inhibitory effect of Oxymatrine on HBsAg and HBeAg increased in a dose-dependent manner from 0.125 to 1 g·L~(-1).The toxicity of Baicailin on cells increased from 0.625 to 2 g·L~(-1),especially when the dose surpassed 1 g·L~(-1).The inhibitory effect of Baicailin on HBsAg and HBeAg increased in a dose-dependent manner from 0.125 to 1 g·L~(-1),but its efficacy was inferior to Oxymatrine's efficacy.Oxymatrine-Baicailin compound had good inhibitory effect on hepatitis B viral antigens secretion,and the inhibition effect of the compound on HBeAg was superior to the effect on HBsAg.The Group C Oxymatrine-Baicailin compound had good synergism inhibition effect on hepatitis B viral antigens secretion and the inhibition rate of the specific group compound was significantly superior to that of Oxymatrine treatment alone(HBsAg:P=0.043;HBeAg: P=0.026).Conclusion Oxymatrine-Baicailin compound has good synergism effect on hepatitis B viral antigens secretion in HepG2.2.2.15 cells.
