The present invention provides an amphiphilic block copolymer for drug delivery and a controlled release system comprising the same copolymer. The copolymer comprises at least one hydrophilic block and at least one hydrophobic block, wherein the hydrophobic block is selected from the group consisting of acrylates, methacrylates, acrylamides, methacrylamides, vinylethers and their aromatic derivatives, wherein at least one hydrophobic block contains an aryl group, which is bound to the hydrophobic block with a degradable linker. The controlled release system of the invention shows high stability and high drug retention when administered in vivo enabling accumulation and drug release at the site of action.
本发明提供了一种用于给药的两亲嵌段共聚物以及由该共聚物组成的控释系统。该共聚物包括至少一个亲水嵌段和至少一个疏水嵌段,其中疏水嵌段选自丙烯酸酯、甲基丙烯酸酯、丙烯酰胺、甲基丙烯酰胺、乙烯基醚及其芳香衍生物组成的组,其中至少一个疏水嵌段含有一个芳基,该芳基用可降解连接剂与疏水嵌段结合。本发明的控释系统在体内给药时具有高稳定性和高药物保留率,可在作用部位蓄积和释放药物。
