摘要 目的研究花色苷矢车菊素-3-葡萄糖苷(Cy-3-G)在Caco-2细胞模型的吸收机制。方法建立Caco-2单层细胞模型,观察Cy-3-G的转运情况。加入不同浓度的维拉帕米(P—gp抑制剂)、MK571(MRP2抑制剂)、根皮苷(SGLT1抑制剂)及根皮素(GLUT2抑制剂),观察P—gp、MRP2、SGLT1及GLUT2等转运蛋白在Cy-3-G肠道吸收中的作用。结果Cy-3-G在Caco-2细胞模型的吸收率随着时间延长逐渐升高,2h时吸收率在0.76%-2.41%之间,但随着花色苷浓度的升高而降低。维拉帕米和MK571对Cy-3-G在Caco-2细胞模型的吸收无影响(P〉0.05),根皮苷和根皮素可显著抑制Cy-3-G的吸收(P〈0.05)。结论P—gp和MRP2对Cy-3-G在肠道的吸收无影响,SGLT1和GLUT2均参与了Cy-3-G在小肠的吸收。 Objective To investigate the absorption mechanism of cyanidin-3-glucoside (Cy-3-G) in small intestine. Methods Caco-2 cell model was established and the transport and absorption mechanism of Cy-3-G in Caco-2 cells was investigated. In order to study the effects of P-glycoprotein (P-gp), multidrug resistance-associated protein 2 (MRP2), sodium-dependent glucose transporter 1 (SGLT1) and glucose transporter 2 (GLUT2) on the intestinal absorption of Cy-3-G, the different concentrations of vcrapamil (P-gp inhibitor), MK571 (MRP2 inhibitor), phlorizin (SGLT1 inhibitor) and phloretin (GLUT2 inhibitor) were added and the absorption of Cy-3-G in Caco-2 cell model was observed. Results The transport rate of Cy-3-G in Caco-2 cell model was 0.76%-2.41% at 2 h. Verapamil and MK571 had no effect on the absorption of Cy-3-G (P〉0.05), but phloridzin and phloretin significantly inhibited Cy-3-G absorption (P〈0.05). Conclusion Cy-3-G was transported by SGLT1 and GLUT2 but not by P-gp and MRP2 in the small intestine.
