Patent ID: 7893226

Claim:
A process for the preparation of a compound represented by the structure of the general formula (A): wherein L is a lipid or a phospholipid; Z is either nothing, ethanolamine, serine, inositol, choline, or glycerol; Y is either nothing or a spacer group ranging in length from 2 to 30 atoms; X is a physiologically acceptable monomer, dimer, oligomer, or polymer, wherein X is a glycosaminoglycan; and n is a number from 1 to 1000; wherein any bond between L, Z, Y and X is either an amide or an esteric bond, comprising the steps of: conjugating L to Z; conjugating Z to Y; conjugating Y to X; wherein if Z is nothing, L is conjugated directly to Y, if Y is nothing, Z is conjugated directly to X, and if Y and Z are nothing, L is conjugated directly to X, thereby preparing a compound represented by the structure of the general formula (A).
