目的:阐述中草药代谢与细胞色素P450酶(CYP450)的关系。方法:查阅近年来国内外相关文献100余篇,从CYP450概述、CYP450研究方法、代谢性相互作用以及中草药-药物相互作用与CYP450之间关系等方面进行文献归纳。结果:CYP450研究方法主要包括体外细胞、亚细胞水平研究及体内研究,CYP450酶活性改变是代谢性相互作用的主要原因,中草药复杂成分对CYP450酶活性影响较大。结论:CYP450在药物代谢中起重要作用,由中草药引起药物相互作用屡的原因大多缘于中草药影响了机体CYP450活性或机体CYP450蛋白表达,导致由CYP450参与代谢的其它药物在机体内代谢特征的改变,引发不良药物反应。
Objective:To outlines the interaction between herbs metabolism and CYP450.Methods:Refer to more than 100 piece of literatures about CYP450 and sum up the article from conception of CYP450,study methods of CYP450,metabolism interaction and herbs metabolism.Results:study methods of CYP450 include methods in vitro and in vivo,and alteration in enzymic activity of CYP450 is reason of metabolism interaction.Conclusions:CYP450 plays an important role in drug metabolism;herbs have complicated ingredients and are reported to revoke some drug interaction often.The reason why drug interaction are caused by herbs is because these herbs affect activity or protein expression of CYP450 in organism and result in alteration of metabolism involved CYP450 of drugs thus to cause adverse drug reaction.
