          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+

          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
