ABSTRACT:
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.
