ABSTRACT
Objective:
To study the mechanisms of absorption and transport of 3-acetyl-11-keto-β-boswellic acid (AKBA) from Boswellia carterif in Caco-2 cell, MDCK-MDR1, and MDCK-Wild cell models.Methods:
The Caco-2, MDCK-MDR1, and MDCK-Wild cell monolayer models were used to study the bi-directional transport of AKBA in apical (AP)→basal (BL) or BL→AP; The concentration of AKBA was measured by LC-MS/MS and apparent permeability coefficient (Papp) was calculated.Results:
Papp (AP→BL) and Papp (BL→AP) values of AKBA (50 μmol/L) in Caco-2 cell model were 7.9 × 10-7 and 1.5 × 10-7 cm/s, respectively; Papp (AP→BL) and Papp (BL→AP) values of AKBA (50 μmol/L) in MDCK-MDR1 cell model were 2.6 × 10-7 and 0.8 × 10-7 cm/s, respectively; Papp (AP→BL) and Papp (BL→AP) of AKBA (50 μmol/L) in MDCK-Wild cell model was 2.4 × 10-7 and 0.6 × 10-7 cm/s, respectively; The rates of efflux (RE) for AKBA in Caco-2 and MDCK-MDR1 cell monolayers were both smaller than 2.Conclusion:
AKBA is not the substrate of P-gp and its absorption rate is low. AKBA is absorbed through the intestinal epithelial cells by active transport absorption and passive diffusion possibly.
