Process for preparing sustained release micelle employing conjugate of anticancer drug and biodegradable polymer

Abstract

The present invention relates to a process of preparing a sustained release micelle by copolymerizing a biodegradable polyester hydrophobic polymer and a hydrophilic polyethylene glycol (PEG) to obtain a block copolymer, reacting the block copolymer with a linker to the hydroxyl group of the block copolymer and conjugating the linker-bound block copolymer to a drug to obtain a micelle monomer, and dispersing the micelle monomer an aqueous solution. The drug-micelle conjugate of the present invention has practical application in anticancer therapy.
