Patent ID: 7034006

Claim:
A phosphatidylethanolamine conjugate according to the formula wherein R 1 is a linear, saturated, mono-unsaturated, or poly-unsaturated, alkyl chain ranging in length from 2 to 30 carbon atoms; R 2 is a linear, saturated, mono-unsaturated, or poly-unsaturated, alkyl chain ranging in length from 2 to 30 carbon atoms; Y is either nothing or a spacer group ranging in length from 2 to 30 atoms, wherein said spacer comprises —CO-alkylene-NH—, —CO-alkylene-CO— or a combination thereof; and X is either a physiologically acceptable monomer, dimer, or oligomer, wherein n is unity, or a physiologically acceptable polymer, wherein n is a number from 1 to 1,000, wherein x is a glycosaminoglycan; wherein if Y is nothing the phosphatidylethanolamine is directly linked to X via a carboxylic group.
