摘要
目的 :建立稳定高效的原代大鼠肝细胞和冻存人肝细胞诱导实验模型,研究SPH0396对CYP1A2和CYP3A4的诱导。方法 :利用探针底物代谢物生成量对CYP3A4和CYP1A2的酶活性进行评价。结果 :SPH0396在0.1mmol/L和1 mmol/L对CYP酶(1A2和3A4)无诱导作用,3 mmol/L时对CYP 3A4无诱导,而对CYP1A2的诱导倍数均大于2,初步认为其诱导CYP1A2,且诱导作用在原代大鼠与冻存人肝细胞中无种属差异。结论 :SPH0396能诱导CYP1A2,需关注SPH0396因诱导CYP1A2而导致临床上发生药物-药物相互作用的可能性。
Objective: To establish a stable and efficient experimental model using primary rat hepatocyte and cyropreserved human hepatocyte so as to study the induction of small molecule compound SPH0396 to CYP1A2 and CYP3A4.Methods: The enzyme activity was evaluated using probe substrates metabolite. Results: SPH0396 had no effect on CYP3A4 at the concentrations of 0.1 ~ 3 mmol/L, suggesting that SPH0396 is not an inducer of CYP3A4. However, significant induction of CYP1A2 was observed at 3 mmol/L of SPH0396 and the induction reached more than two times. There is no difference between rat and human hepatocytes. Conclusion: SPH0396 may cause drug-drug interaction via induction of CYP1A2 and attention should be paid in clinic to the potential of drug-drug interaction resulting from its induction to CYP1A2.
