Polymer derivatives of camptothecins |
abstract |
To provide a water-soluble derivative of camptothecins having high therapeutic effect and suitable for cancer chemotherapy. A water-soluble polymer derivative of camptothecins excellent in sustained release property by esterifying a carboxylic acid group of a polymer of polyethylene glycols and polycarboxylic acid with a phenolic hydroxyl group of phenolic camptothecins. |
