PEPTIDE BIFONCTIONNEL

摘要

The bifunctional peptide is capable of activating collagen synthesis and inhibiting the production of matrix metallo-proteinases. The peptide has a sequence including three peptide parts A, B and C. The first peptide part A corresponds to a hexapeptide repeated at least three times, the part A being capable of bonding to a receptor elastin-binding protein in order to stimulate collagen synthesis. The second peptide part B corresponds to a tetrapeptide capable of acting as a competitive inhibitor of urokinase protease and of being cleaved by said protease. The third peptide part C corresponds to a tripeptide occupying at least one active site of the matrix metallo-proteinases in order to enable inhibition of the proteinases. The present invention further concerns a cosmetic and/or pharmaceutical composition incorporating the bifunctional peptide.
