A conjugate of a synthetic polypeptide containing RGD or (dR) GD and a biodegradable polymer, such as hyaluronic acid or chondroitin sulfate is disclosed. Methods of making the conjugate and using it to aid wound healing by providing a temporary matrix are disclosed.

Polypeptide-polymer conjugates active in wound healing

The present invention provides methods for reducing or inhibiting wound contraction in a subject having a wound comprising administering to the subject a pharmaceutical composition comprising a peptide or a polypeptide. The invention provides, for example, a method of reducing or inhibiting wound contraction comprising the administration of a pharmaceutical composition comprising a peptide having more than three consecutive basic amino acids. The invention also provides a method of reducing or inhibiting wound contraction comprising the administration of a pharmaceutical composition comprising a peptide containing the sequence arginine-glycine-aspartic acid and a basic amino acid sequence or a pharmaceutical composition comprising a peptide containing therein a sequence of six consecutive amino acid residues of which at least about four of the six amino acid residues are basic amino acid residues. The invention also provides a method of reducing or inhibiting wound contraction comprising the administration of a pharmaceutical composition comprising decorin.

Compositions that inhibit wound contraction and methods of using same

The present invention provides novel conjugates of a synthetic polypeptide containing RGD or (dR)GD and a biodegradable polymer, hyaluronate. The conjugates are prepared by any one of three different methods provided by the present invention: (1) an epoxide method (2) a sodium periodate method, and (3) a tresyl chloride method. The conjugates prepared by these methods are useful to aid in wound healing and tissue regeneration by providing a temporary matrix for tissue repair. The invention also provides novel RGD-peptides.

Immobilization of peptides to hyaluronate

The present invention provides methods for reducing or inhibiting wound contraction in a subject having a wound comprising administering to the subject a pharmaceutical composition comprising a peptide or a polypeptide. The invention provides, for example, a method of reducing or inhibiting wound contraction comprising the administration of a pharmaceutical composition comprising a peptide having more than three consecutive basic amino acids. The invention also provides a method of reducing or inhibiting wound contraction comprising the administration of a pharmaceutical composition comprising decorin.
