Biodegradable copolymers linked to segment with a plurality of functional groups |
摘要 |
Biocompatible biodegradable polymer or copolymer is capped at one end and has free hydroxyl at the other end. The free hydroxyl can be reacted to link a plurality of functional groups some or each of which can be reacted to attach directly or via a spacer molecule a moiety containing an aminoxyl-containing radical or to a moiety comprising other drug molecule residue or a moiety comprising other biologically active agent residue.
