A doxorubicin conjugated prodrug incorporated acid-sensitive linkage between drug and Pluronic F127-chitosan (F127-CS) polymer was successfully synthesized. Subsequently a pH-sensitive polymeric micelle system was designed based on the conjugated prodrugs (F127-CS-DOX) to co-deliver doxorubicin and paclitaxel. Paclitaxel (PTX) was physically entrapped in the hydrophobic inner core of the micelles simultaneously. The structures of conjugates were analyzed by means of 1H NMR and UV-vis spectrum. Size distribution and morphology of the micelles were observed by dynamic light scattering (DLS) and transmission electron microscopy (TEM). The results indicated that obtained micelles had good dispersity and the diameter was between 56.3 and 403.4 nm. The loading of PTX into the micelle increased with higher DOX content. DOX and PTX release from polymeric micelles followed an acid-triggered manner. Furthermore, in vivo pharmacokinetic study also showed that the area under the plasma concentration time curve (AUC0-) values of PTX and DOX for PTX-loaded F127-CS-DOX micelles in rats were 3.97 and 4.38-fold higher than those for PTX plus DOX solution. These results suggested the PTX-loaded F127-CS-DOX micelles would be a promising carrier for co-delivering DOX and PTX.
