Abstract: A hydrophobic grafted collagen, a method for preparing same and use thereof, in particular in therapy, are provided. Hydrophobic substances or molecules are grafted by covalent bonds on reactive amino acid residues of collagen molecules. The chemical linkages serve to modify the physico-chemical and biological properties of collagen and/or its derivatives. In particular, the introduction of hydrophobic residues enable the hydrophilic character of collagen to be modulated and its chemotactic properties involved in cell adhesion and growth to be modified.

Abstract: The present invention relates to a modified collagen which is soluble in water and/or in aprotic polar organic solvents and which comprises free or substituted thiol functional groups carried by residues of cysteine or its derivatives, the residues being, at least partially, residues which are directly grafted onto the collagen chain, characterized in that it possesses a level of free or substituted thiol functional groups greater than 0.3, preferably 0.5 mM/g of collagen. The invention also relates to the production of these new collagen derivatives and to their application in the preparation of biomaterials, it being possible for the latter to be used especially in the manufacture of implants, prostheses or the like.

Abstract: The present invention relates to a crosslinkable modified collagen which is soluble in water and/or in aprotic polar organic solvents and which contains free or substituted thiol groups carried by residues of cysteine or derivatives thereof, at least some of the residues being fixed to the collagen via spacer compounds.
