| Abstract: | Objective To investigate the absorption characteristics of harmine derivative DH-004 in rat intestine and its possible absorption mechanism.Methods The concentration of DH-004 in perfusion solution was determined by UPLC,and in situ rats single pass perfusion model was used to investigate the absorption characteristics of different concentrations of DH-004 in different intestinal segments.Results DH-004 can be absorbed in all intestinal segments of rats.The absorption rate constants(Ka)of DH-00420.0μg·mL-1 in duodenum,jejunum,ileum and colon were(11.66±3.84)×10-2,(10.85±2.65)×10-2,(7.48±1.70)×10-2 and(4.75±1.14)×10-2 min,separately.The apparent permeability coefficients(Papp)were(1.47±0.33)×10-2,(1.55±0.20)×10-2,(1.25±0.10)×10-2 and(0.98±0.22)×10-2 cm·min-1,separately.Ka of DH-004 in duodenum and jejunum were significantly higher than those in ileum and colon(all P<0.05)Conclusion DH-004 can be absorbed in all segments of the rat intestine with different degrees.The main absorption segments for DH-004 may be the duodenum and jejunum. |
