目的:探究齐墩果酸对细胞色素P450-亚酶CYP1A2酶活性的影响。方法:受试者服用一周齐墩果酸后,再服用探针药物咖啡因,采用RP-HPLC测定探药的浓度以及相应代谢产物的浓度。结果:咖啡因的代谢受到了明显的抑制,其达峰的时间和消除的半衰期均显著的增加。结论:服用齐墩果酸对CYP1A2酶活性具有显著的抑制作用。
Objective: To investigate the effect of oleanolic acid on the activity of CYP1A2 cytochrome P450-enzyme. METHODS: After taking oleanolic acid for one week, the subjects took caffeine as the probe drug. The drug concentration and the concentration of the corresponding metabolites were determined by RP-HPLC. Results: The metabolism of caffeine was significantly inhibited, and its peak time and elimination half-life were significantly increased. Conclusion: Oleanolic acid has a significant inhibitory effect on CYP1A2 activity.
