    摘要: Disclosed are a polymer micelle composition for treatment of resistant cancer cells that contains an amphiphilic double block copolymer and taxane and a P-glycoprotein inhibitor of cyclosporin as its active ingredients, and a method of preparing the same. Said polymer micelle composition for treatment of cancer resistant cells is accumulated in cancer tissue at high concentrations, and has the advantages that it exhibits superior anti-cancer effects for the cancer cells that have exhibited resistance due to over-expression of P-glycoprotein by the taxane anticancer agent in said cancer tissue, and does not cause hypersensitive reactions due to the use of a solubilizer.

    摘要: The present invention relates to an amphiphilic block copolymer of a hydrophilic block and a hydrophobic block with a terminal hydroxyl group wherein the terminal hydroxyl group of the hydrophobic bock is substituted with a tocopherol or cholesterol group. It also relates to polymeric compositions capable of forming stable micelles in an aqueous solution, comprising the amphiphilic block copolymer and a polylactic acid derivative wherein one or more ends of the polylactic acid are covalently bound to at least one carboxyl group.
