| 摘 要： | 目的：体外研究大鼠肝微粒体中CH330331代谢的酶促动力学,并利用＂Cocktail＂探针药物模型,研究CH330331对主要CYP450亚型的体外抑制作用。方法：优化CH330331在大鼠肝微粒体中孵育的条件,并进行酶促动力学研究;探讨体外＂Cocktail＂探针药物模型的组成,并研究CH330331对CYP450亚型的体外抑制作用。结果：CH330331代谢的酶促动力学参数：最大反应速率（Vmax）为2.08μmol/（min.mgpro-tein）,米氏常数（Km）为18.96μmol/L。CH330331对大鼠CYP1A2、CYP2C9和CYP2D6有弱抑制作用,对大鼠CYP2C19、CYP2E1和CYP3A4没有抑制作用。结论：临床使用中CH330331可以增加主要通过CYPCYP1A2,CYP2C9和CYP2D6代谢的药物浓度。 |

| Abstract: | AIM：To study the metabolic kinetics of CH330331 in rat liver microsome,and its inhibition on CYP450 subtypes in the ＂cocktail＂ models.METHODS：The incubation parameters in rat liver microsome were optimized and were the Michaelis-Menten parameters Km and Vmax estimated the component of probe inhibitors in ＂cocktail＂ models were also confirmed and the effect of CH330331 on main subtypes of cytochrome P450 studied.RESULTS：The Km and Vmax of CH330331 were 18.96 μmol/L and 2.08 μmol/（min·mg protein）,respectively.CH330331 had a weakly inhibition to the activity of CYP1A2,CYP2D6 and CYP2C9 but had no effect on CYP2C19,CYP2E1,and CYP3A4.CONCLUSION：CH330331 can increase the blood concentration of those drugs that are metabolized mainly by CYP1A2,CYP2D6 and CYP2C9. |
