Abstract

Three types of amphiphilic dextran derivatives were synthesized via the connection of different diamine compounds between the carboxyl group of stearic acid (SA) and aldehyde group of oxidized dextran. These three amphiphilic dextran derivatives self-assemble to form polymer micelles in aqueous medium. The critical micelle concentration depended on the graft ratio of SA, which ranged from 0.0700 to 0.158 mg mL−1. These three amphiphilic dextran micelles can form typical core–shell structures of various sizes. Curcumin (Cur) was used as a model drug, and all amphiphilic micelle dextran derivatives had excellent drug loading capacity and drug encapsulation efficiency. The in vitro drug release from amphiphilic dextran derivatives/Cur micelles could be prolonged by adjusting the type of diamine compounds and composition of Cur content. These results show the superior properties of polymer micelles and suggest that these micelles are promising carriers for drug delivery systems.
