Effect of different inhibitors on the transport of TSG across Caco-2 cell monolayer. The data are presented as the apparent permeability (Papp, cm/s). Effect of P-glycoprotein (P-gp) inhibitor (verapamil hydrochloride and probenecid) and multidrug resistance-associated protein 2 (MRP2) inhibitor (probenecid) on Caco-2 cell monolayer for TSG. AP-BL side (a); BL-AP side (b). p < 0.05 (*), p < 0.01 (**), comparison with control. All results are expressed as mean ± SD (n = 3)
