Non-peptide polyamino acid bioerodible polymers

摘要

A novel bioerodible polymeric composition is provided comprising a plurality of monomer units of two or three amino acids which are polymerized via hydrolytically labile bonds at their respective side chains rather than at the amino or carboxylic acid terminals by amide bonds. Such polymers are useful for controlled release applications in vivo and in vitro for delivery of a wide variety of biologically and pharmacologically active ligands.
