摘 要 目的 考察复方曲肽注射液对细胞色素P450(CYP450)酶活性的体内外影响。方法 将人肝微粒体与复方曲肽注射液(体

用超高效液相色谱-串联质谱(UPLC-MS/MS)技术检测相应代谢产物的生成量,并计算半数抑制浓度(IC50 );将人原代肝细胞与复
方曲肽注射液(体积分数0.05%~10%)或CYP1A2、CYP2B6、CYP3A4阳性诱导剂共孵育48 h后,采用实时荧光定量聚合酶链式
反应法测定上述酶 mRNA 的相对表达量(即诱导倍数)。将雄性 SD 大鼠随机分为对照组(生理盐水+CYP1A2、CYP2B6、
CYP2C8、CYP2C9、CYP2C19、CYP2D6、CYP3A4 探针底物 8、2、1、1、10、10、8 mg/kg)和实验组(复方曲肽注射液 0.9 mL/kg+
CYP1A2、CYP2B6、CYP2C8、CYP2C9、CYP2C19、CYP2D6、CYP3A4 探针底物 8、2、1、1、10、10、8 mg/kg),每组 6 只,采用 Cocktail
探针药物法,以UPLC-MS/MS技术为手段,检测各探针底物的药动学参数。结果 经0.05%~10%复方曲肽注射液处理后,人肝微
粒体中 CYP2B6、CYP2C8、CYP2C19 的活性无明显变化,未能拟合出 IC50;CYP1A2、CYP2C9、CYP2D6、CYP3A4 的 IC50分别为
419.90%、97.78%、176.00%、19.42%;经0.05%~10%复方曲肽注射液处理后,人原代肝细胞(批号MHK)中CYP3A4 mRNA的平均
诱导倍数为4.88(且有2个浓度点的平均诱导倍数>2);经复方曲肽注射液干预后,CYP2C8、CYP2C9、CYP2C19底物的AUC0-t、
AUC0-∞均显著升高,CYP2C8、CYP2C19底物的CL均显著降低,CYP2C9酶底物的t1/2显著延长(P<0.05)。结论 复方曲肽注射液
对人肝微粒中CYP1A2、CYP2B6、CYP2C8、CYP2C9、CYP2C19、CYP2D6、CYP3A4活性无明显的体外抑制作用,对人原代肝细胞
中CYP3A4 mRNA的表达有体外诱导作用,对大鼠CYP2C8、CYP2C9、CYP2C19活性有体内抑制作用。

ABSTRACT OBJECTIVE To investigate the effects of Compound troxerutin and poreine cerebroside injection on the activity of
cytochrome P450 (CYP450) enzyme in vivo and in vitro. METHODS Human liver microsomes were incubated with Compound
troxerutin and poreine cerebroside injection (volume fraction 0.05%-10%) and the specific probe substrates of CYP1A2, CYP2B6,
CYP2C8, CYP2C9, CYP2C19, CYP2D6 and CYP3A4 for 30 min. The production of corresponding metabolites was detected by
ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), and the half inhibitory concentration
(IC50 ) was calculated. The relative mRNA expression (i.e. induction multiple) of CYP450 enzyme was determined by real-time
fluorescence quantitative PCR after human primary hepatocytes were incubated with Compound troxerutin and poreine cerebroside
injection (volume fraction 0.05%-10%) or 3 positive inducers of CYP1A2, CYP2B6, CYP3A4 for 48 hours. Male SD rats were
randomly divided into control group (normal saline+probe substrates of CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19,
CYP2D6, CYP3A4 8, 2, 1, 1, 10, 10, 8 mg/kg) and experimental group (Compound troxerutin and poreine cerebroside injection 0.9
