Active-targeting-type polymer derivative, composition containing said polymer derivative, and uses of said polymer derivative and said composition |
abstract |
Provided is a polymeric micelle type DDS preparation that may efficiently exhibit pharmacological activity effects by enhancing migration characteristics, penetrability, and retention characteristics toward a diseased target tissue such as a tumor tissue or an inflammation-affected tissue, and thereby enhancing the action of a pharmacologically active substance. Disclosed is a block copolymer (A) having a hydrophilic polymer segment linked to a hydrophobic polymer segment, the hydrophilic polymer segment containing a polyethylene glycol chain, and the hydrophobic polymer segment containing a polyamino acid chain having a hydrophobic substituent in a side chain, wherein the hydrophilic polymer segment has a target binding site bonded thereto, and the main chain polymer combining the polyethylene glycol chain and the polyamino acid chain has a molecular weight of not less than 2 kilodaltons and not more than 10 kilodaltons. |
