| 摘 要： | 以奥美拉唑、 苯妥英、 卡马西平和非那西丁为检测肝药酶细胞色素P450酶(CYP450)亚型的专属探针药物, 通过原型药物减少量测定法考察药物体外代谢的变化, 评价人参皂苷Rb1对CYP450不同亚型酶的作用. 结果表明, P2C9, P2C19和P3A4实验组与对照组差异不显著, P1A2实验组与对照组差异显著, 表明人参皂苷Rb1能诱导P1A2亚型酶的活性, 促进底物与酶反应, 加快底物的代谢, 而对P2C9, P2C19和P3A4三个亚型酶有弱的诱导或无诱导作用. 根据快速分离液相色谱-质谱联用(RRLC-MS/MS)检测结果推断, 人参皂苷Rb1在CYP450酶中的代谢产物可转化为人参皂苷Rb1氧化产物(Rb1+O)及人参皂苷Rd和F2.

| Abstract: | The effect and metabolisms of ginsenoside Rb1 were studied on cytochrome P450s(CYP450). The induction or inhibition effects of CYP450 enzymes were evaluated by investigating the changes of probe drug in concentration. The metabolites of ginsenoside Rb1 including ginsenoside Rd, ginsenoside F2 and the oxidation of ginsenoside Rb, were found and identified in CYP450 enzyme with RRLC-MS/MS. The difference between the experimental group and control group was not significant except CYP1A2 group, indicating that ginsenoside Rb1 has more induced effect to the CYP1A2 group than the others. Ginsenoside Rb1 promoted reaction and speed up the metabolism of probe drug. The method can effectively and easily analyze the impact on the enzyme and possible metabolites. |
