제목 Reduction-responsive, Diselenide Core-Cross-Linked Polymeric Micelles for Doxorubicin Delivery for application in Cancer Therapy
초록 The design and fabrication of smart delivery systems that can efficiently deliver a payload to a targeted site in a controlled manner are immensely desirable in chemotherapy. We report the reduction-responsive drug delivery property of core-cross-linked (CCL) micelles of poly (ethylene oxide) 5k-b-poly (furfuryl methacrylate) 2k (PEO5k-b-PFMA2k) block copolymers produced using Diels-Alder reaction. Doxorubicin (DOX) was loaded into hydrophobic PFMA cores of the polymeric micelles, which were subsequently cross-linked with diselenide-containing cross-linker. DOX-loaded CCL micelles were stable at pH 7.4, while a significant DOX release was observed at pH 5.0 due to the protonation of DOX. The non-CCL and CCL micelles were found non-toxic to HFF-1 normal cells. However, DOX encapsulated CCL micelles showed significant cytotoxicity in HeLa cells. The confocal images showed that the DOX-loaded CCL micelles can quickly be internalized and efficiently deliver DOX into the HeLa cells.
