제목 Interface-Cross-linked Micelles of Poly(D,L-lactide)-b-poly(furfuryl methacrylate)-b-poly(N-acryloylmorpholine) for Near-infrared-triggered Drug Delivery Application
초록 We report a NIR-responsive interface cross-linked (ICL) micelles prepared by usingthe Diels-alder click creaction between poly(D,L-lactide)-b-poly(furfurylmethacrylate)-b-poly(N-acryloylmorpholine) (PLA-b-PFMA-b-PNAM) triblockcopolymers and a diselenide cross-linker, bis(maleimidoethyl)3,3’-diselanediyldipropionoate (BMEDSeDP). PLA-b-PFMA-b-PNAM was synthesized bythe sequential RAFT polymerization of FMA and NAM using PLA-macro‐chaintransfer agent (PLA-CTA) as a macro-initiator. The release of DOX from the ICLmicelles was suppressed (ca. 11% in 60 h) under physiological conditions (pH7.4), indicating that the interfacial cross-linking protected the drug release from the micelles. The in vitro analysis indicated that the ICL was not cytotoxic against normal HFF-1 cells (non-cancerous), while higher antitumoractivity towards HeLa cells were exhibited by DOX-loaded ICL micelles. The developed ICL micelles would provide a promising robust anticancer drug delivery system.
