| abstract |
This invention is a water-soluble high molecular polymerized drug comprising a water-soluble block copolymer consisting of a hydrophilic segment and a hydrophobic pharmacological-functioning segment to side chain of which a drug is bonded. The hydrophilic first segment of the present invention include polyethylene glycol, polysaccharides, polyacrylamide, and so on. The hydrophobic segment being attached to a drug include polyaspartic acid, polyglutamic acid, polylysine, or derivatives thereof. Drugs to be attached to the hydrophobic segment include anti-cancer drugs, drugs for central nerve, drugs for peripheral nerve, drugs for circulatory organs, and so on. |
