Fabrication of TPGS-Stabilized Liposome-PLGA Hybrid Nanoparticle Via a New Modified Nanoprecipitation Approach: In Vitro and In Vivo Evaluation.

abstract：PURPOSE:Three types of acyl tetragastrin (TG), acetyl-TG (C2-TG), butyryl-TG (C4-TG) and caproyl-TG (C6-TG) were synthesized and their in vitro intestinal permeability characteristics were examined using Caco-2 monolayers. METHODS:The disappearance of acyl-TGs from the apical side of Caco-2 monolayers was estimated by...
