Biodegradable Copolymers Linked To Segment With A Plurality Of Functional Groups
View pageUS Patent:
20030027940, Feb 6, 2003
Filed:
Mar 20, 2002
Appl. No.:
10/101408
Inventors:
Meidong Lang - Ann Arbor MI, US
Chih-Chang Chu - Ithaca NY, US
Chih-Chang Chu - Ithaca NY, US
International Classification:
C08F002/00
US Classification:
525/450000
Abstract:
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.
