Absorption mechanism of oxysophocarpine across Caco-2 cell monolayer mode].

To investigate the absorption mechanism of oxysophocarpine across Caco-2 cell monolayer model. The safety concentration of oxysophocarpine in Caco-2 cell was first selected by using MTT method. Then the Caco-2 cell monolayers drug transport model was assigned to study the bi-direction transport mechanism of oxysophocarpine by evaluating the influent factors such as time, concentration, pH, P-gp inhibitor of verapamil, on its absorption characterization. In the Caco-2 cell monolayer model, the transport volume was correlated positively with the time and concentration of oxysophocarpine, and affected by pH value. Verapamil had no influence on its transport since the transport of oxysophocarpine from apical (AP) to basolateral (BL) was similar to the transport from basolateral to apical. The intestinal absorption mechanism of oxysophocarpine was deduced as passive transference by Caco-2 cell monolayer model.
