Methods Seven probe drugs were incubated with or without methyl protodioscin respectively in human microsomes. The specific substrates used in this study were caffeine (CYP1A2), dextromethorphan (CYP2D6), tolbutamide (CYP2C9),-mephenytoin (CYP2C19), chlorzoxazone (CYP2E1), coumarin (CYP2A6) and midazolam (CYP3A4). The concentrations of the substrate metabolites (paraxanthine, dextrorphan, 4-hydroxytolbutamide, 4-hydroxymephenytoin, 6-hydroxychlor-zoxazone, 7-hydroxycoumarin and 1-hydroxymidazolam) were determined by HPLC and LC-MS/MS. Results MPD 1-10 μmolL^(-1 had no significant inhibition on the activities of the seven cytochrome P450 enzymes.

将MPD和CYP450酶7种亚型的特异性探针底物咖啡因(CYP1A2)、右美沙芬(CYP2D6)、甲苯磺丁脲(CYP2C9)、s-美芬妥因(CYP2C19)、氯唑沙宗(CYP2E1)、香豆素(CYP2A6)及咪达唑仑(CYP3A4)与人肝微粒体进行孵化反应，采用HPLC和LC-MS/MS法测定对应的7种代谢产物（1，7-二甲基黄嘌呤、去甲右美沙芬、4-羟基甲苯磺丁脲、4-羟基美芬妥因、6-羟基氯唑沙宗、7-羟基香豆素和1-羟基咪达唑仑）的浓度，通过与对照组比较，确定MPD对以上7种酶活性的影响。

In the second chapter of part one, a lipophilic fluorescent dye, coumarin-6,serving as a nanoparticle probe, was incorporated in Lf-NP_ to investigate its braindrug delivery characteristics in a bEnd.3 BBB model with unconjugated nanoparticleNP_(PLGA as control.

第一部分第二章采用香豆素-6作为纳米粒的荧光探针，bEnd.3作为体外BBB模型，以未连接Lf的普通纳米粒NP_为对照，对Lf-NP_的脑内递药特性进行了体外评价。

In DMSO, the polymerization of methyl methacrylate could be carried out efficiently. However the photopolymerization was inhibited in acetonitrile. It was ascribed to the complex formed between coumarin 1 and HTIB photolyzed to unreactive species after irradiation in acetonitrile.

在一般极性溶剂中如DMSO中能有效地引发甲基丙烯酸甲酯光聚合，而在电子受体性质的极性溶剂如乙腈中，光聚合反应受阻，这归结于香豆素1与羟基苯基碘鎓盐形成络合物，使得光反应后生成不具活性的产物。
