第一节 概 述 第二节 药物代谢的酶( E n z y m e s f o r D r u g M e t a bo lism) 第三节 第Ⅰ相的生物转化(PhaseⅠ B iotransformation)

第1相生物转化是官能团化反应,是在体内多种酶系 的催化下,对药物分子引入新的官能团或改变原有的官能团 的过程。参与药物体内生物转化的酶类主要是氧化—还原酶和 水解酶。本节主要介绍细胞色素P—450酶系、还原酶系、过氧 化物酶和其它单加氧酶、水解酶

第Ⅱ相生物转化又称轭合反应( Conjugation),是 在酶的催化下将内源性的极性小分子如葡萄糖醛 酸、硫酸、氨基酸、谷胱甘肽等结合到药物分子 中或第I相的药物代谢产物中。通过结合使药物 去活化以及产生水溶性的代谢物,有利于从尿和 胆汁中排泄
