Abstrakt: Nanostructured lipid carriers (NLC) have been considered as promising vehicles for oral delivery of taxanes, such as docetaxel (DTX). However, the low drug loading capability (∼5%, w/w) has greatly limited their clinical application. In response to this challenge, a novel lipophilic oleate prodrug of DTX (DTX-OA) was synthesized and efficiently encapsulated in NLC using core-match technology, in which liquid lipid (OA) was used as core matrix to enhance compatibility with DTX-OA. DTX-OA-NLC showed uniform particle size of about 100nm with markedly high drug loading capability (∼23% of DTX, w/w) compared with DTX-NLC (∼5%, w/w). Besides, DTX-OA-NLC showed better colloidal stability and slower drug release property compared with DTX-NLC. The prepared NLC could be accumulated more easily in MDCK cells than drug solution, and clathrin-mediated endocytosis was the main endocytosis pathway. In situ single-pass intestinal perfusion (SPIP) and intestinal biodistribution studies demonstrated the improved membrane permeability and intestinal wall bioadhesion of NLCs. The bioavailability of DTX-OA-NLC showed 4.04-fold and 2.06-fold higher than DTX solution and DTX-NLC, respectively. These results suggest that the core-matched prodrug-NLC is a promising platform to facilitate the oral delivery of DTX.
