| 摘 要： | 目的:研究左金丸类方中4种生物碱的转运特征并比较其差异。方法:采用LC-MS/MS法测定左金丸类方中4种生物碱在Caco-2细胞上的转运特征,研讨其转运差异的机制。结果:环孢素A和维拉帕米均可增加4种生物碱的Papp(AP-BL),降低其Papp(BL-AB);MK-571对其转运均无影响;左金丸中的4种生物碱的Papp(AP-BL)均较黄连组增大;甘露散、茱萸丸中的药根碱、黄连碱和小檗碱的Papp(BL-AP)均较黄连减小。结论:小檗碱、黄连碱、药根碱和巴马汀均为P-gp底物,而非MRP2底物;吴茱萸可能具有抑制P-gp活性的作用。

| Abstract: | To study the transport character and mechanisms of berberine,palmatine,jateorhizine and coptisine in Zuojin Wan and its similar formulae by using Caco-2 cell transport model and with ciclosporin A and verapamil as P-glycoprotein(P-gp) inhibitors and MK-571 as multidrug resistance-associated protein 2(MRP2) inhibitor.In the transport experiment,Papp(AP-BL) of the 4 alkaloids were lower than that at the Papp(BL-AB);ciclosporin A and verapamil increased Papp(AP-BL) but decreased Papp(BL-AB) of the 4 alkaloids,and decreased ERs by more than 80%;MK-571 had no influence on the transmembrane transports of all the 4 alkaloids;Papp(AP-BL) of the 4 alkaloids in Zuojin Wan were larger than that of the 4 alkaloids in coptis chinensis;Papp(BL-AP) of jateorhizine,coptisine and Berberine in Ganlusan and Zhuyuwan were larger than that of the 3 alkaloids in coptis chinensis.Berberine,palmatine,jateorhizine and coptisine were all P-gp substrates other than MRP2 substrates;and Evodiae fructus might have inhibition effects on P-gp. |
