The preparation, characterization, release, and in vitro cytotoxicity of a biodegradable polymeric micellar formu- lation of paclictaxel (PTX) were investigated. The micelles based on thermosensitive and degradable amphiphilic polyas- partamide derivatives containing pendant aromatic structures (phe-g-PHPA-g-mPEG) were prepared by a quick heating method without using toxic organic solvent. Dynamic light- scattering results show that the micelles are stable upon dilu- tion under physiological conditions and the destabilization of the micelles is pH-dependent and the phe-g-PHPA-g-mPEG polymers are biodegradable. PTX was loaded into the phe-g- PHPAs-g-mPEG micelles with encapsulation efficiency of >90%, resulting in a high drug loading content (up to 29%). PTX-loaded micelles had a mean size around 70 nm with narrow size distribution (polydispersity index, <0.1). The PTX- loaded micelles showed sustained drug release and obvious anticancer activity similar to Taxol against HepG2 cells, whereas blank micelles were nontoxic. The present results sug- gest that the thermosensitive and biodegradable phe-g-PHPA- g-mPEG micelles are a promising delivery system for the hydrophobic drugs. V C 2013 Wiley Periodicals, Inc. J.
