In vitro and in vivo evaluation of docetaxel loaded biodegradable polymersomes.
Formulation of docetaxel (DOC), a hydrophobic anticancer drug, was successfully achieved in poly(gamma-benzyl L-glutamate)-block-hyaluronan polymersomes using a simple and reproducible nanoprecipitation method. The prepared DOC loaded polymersomes (PolyDOC) was stable either in solution or in a lyophilized form, and showed controlled release behaviour over several days. PolyDOC showed high in vitro toxicity after 24 h in MCF-7 and U87 cells compared to free DOC. Biodistribution data demonstrated that (99m)Tc labelled PolyDOC t(1/2) and MRT significantly increased compared to a DOC solution (DS). In addition, PolyDOC uptake in Ehrlich Ascites Tumor (EAT) tumor bearing mice was larger at each time point compared to DS, making such a polymer vesicle formulation an efficient drug nanocarrier for improved DOC cancer therapy.
