The present study takes the advantages of nanocarriers combined with a ligand (galactose) anchoring to orally deliver RES in an attempt to improve its bioavailability and pharmacological activity. Methods: RES-loaded galactosylated nanoparticles (RES-GNPs) were prepared by solvent diffusion technique using poly(lactic-co-glycolic acid), synthesized N-oleoyl-d-galactosamine and Tween 80. RES-GNPs were characterized by particle size, morphology, entrapment efficiency (EE) and in vitro release. Oral bioavailability and in vitro anti-inflammatory activity were investigated in rats and lipopolysaccharides-induced RAW 264.7 cells, respectively. Results: The resulting RES-GNPs were 108.4 nm around in particle size with a polydispersity index of 0.217. Furthermore, RES-GNPs possessed a high EE and a slow drug release in water. After oral administration, RES-GNPs significantly enhanced the oral bioavailability of RES, up to 335.7% relative to RES suspensions. In situ single-pass intestinal perfusion and cellular uptake experiments showed that GNPs could improve the intestinal permeability and transcellular transport of RES. Moreover, the anti-inflammatory efficacy of RES-GNPs in RAW 264.7 cells model was superior to free RES and RES-GNPs. Conclusion: The results indicate that RES-GNPs can effectively promote the intestinal absorption of RES and strengthen its bioactivity, which may be a promising system for the treatment of inflammatory diseases.
