A novel hydrophilic conjugate of arginine-glycine-aspartic acid (RGD) and polyethylene glycol (PEG), i.e., RGD-PEG Mw (M W = 300, 600, 1000 or 4000), was synthesized and employed in epirubicin (EPI) loaded poly L-lactic acid (PLLA) nanoparticles (NPs) to improve its tumor targeting effect. In vitro studies were performed to assess EPI release from NPs in tumor-mimic acidic medium, cytotoxicity and cell cycle assay in HepG2 cells, and cellular uptake kinetics in four types of tumor cells… CONTINUE READING
