Biodegradable Self-Assembled Micelles Based on MPEG-PTMC Copolymers: An Ideal Drug Delivery System for Vincristine
Abstract:
Despite advantageous properties, micelles using methoxy poly(ethylene glycol)-poly(trimethylene carbonate) (MPEGPTMC) have not been widely studied. In this work, we aim to develop a novel vehicle for vincristine (VCR) based on a MPEG-PTMC micelle system. MPEG-PTMC with a series of molecular weights were synthesized and screened for the appropriate range for forming stable VCR micelles. The prepared micelles were then characterized in vitro and in vivo . VCR micelles presented high stability and ideal sustained release profile. The passive targeting effect was also enhanced compared with liposomal VCR. These results provide critical data to give the first clues regarding novel VCR micelles which exhibit potential for clinical application.
