Definitions

  • the present invention relates to a new topical use, cosmetic or therapeutical, of a peptidic mixture comprising a GHK type tripeptide (hereafter symbolised A-GHK-B) and a GQPR type tetrapeptide (hereafter symbolised A-GQPR-B, SEQ ID NO: 1), for the treatment of skin (including scalp skin) of human or animal mammals.
  • the invention aims for the cosmetic, hygiene and personal care, and dermopharmacy industries.
  • the GQPR Glycine-Glutamine-Proline-Arginine, SEQ ID NO: 2
  • GHK Glycine-Histidine- Lysine sequences belong to Matrikines, known to participate in the reconstruction of the extracellular matrix of the connective tissue.
  • a composition comprising a mixture of Pal-GHK tripeptide and Pal-GQPR tetrapeptide (SEQ ID NO: 3) in a physiologically acceptable excipient is marketed as anti- wrinkle active by the Applicant Sederma under the trade name MatrixylTM3000 (WO 2005/048968).
  • Dermis is composed of a part called deep reticular dermis and an upper part called papillary dermis which is in contact with the epidermis via the dermal-epidermal junction (DEJ).
  • DEJ dermal-epidermal junction
  • the fibre network of the papillary dermis is different, more fragile.
  • the proportions of collagen I and III are different and the network contains more glycoproteoglycans and glycosaminoglycans.
  • This area also contains fibroblasts that have a very important role in the formation of the epidermis.
  • the papillary dermis forms thus an important area of the skin, but fragile, especially very sensitive to UV radiations.
  • the upper part of the papillary dermis is slightly echogenic and can thus be visualized by ultrasound imaging (dermal fibers less dense returning less echos). This part is thus also called the SLEB “Sub- epidermal Low Echogenic Band” (or also called SENEB, "sub-epidermal non-echogenic band”). It has been shown that the thickness of the papillary dermis SLEB increases with time and exposure to solar radiations.
  • the present invention aims to provide a composition adapted to act specifically and efficiently on the papillary dermis, especially for the treatment of skin affected by a photo-induced and/or chronological aging.
  • B OH, OR 1; NH 2 , NHRi, NRiR 2 , Ri and R 2 being, independently of one another, selected from an alkyl, aryl, aralkyl, alkylaryl, alkoxy and aryloxy group, which may be linear, branched, cyclic, polycyclic, unsaturated, hydroxylated, carbonylated, phosphorylated and/or sulfured, said group which may have a heteroatom in its skeleton including O, S and/or N.
  • A is at the peptide N terminal end (conventionally at left).
  • papillary dermis can be reconstructed (by reducing the SLEB papillary dermis thickness and improving its density). Thanks to the invention, the papillary dermis can be rejuvenated.
  • a mixture of A-GHK-B and A-GQPR-B (SEQ ID NO: 1) peptides, or of their derivatives or analogs, can be used for preventing and/or treating aging of the papillary dermis, especially for the treatment of a skin overexposed to solar radiations (photo-induced aging).
  • the application areas are multiple, wherever necessary, damaged areas and/or areas where the dermis is particularly sensitive, for example the lips.
  • the eye contour and the neckline may be areas as well covered by the present invention uses. Uses can also be performed as a preventive measure.
  • the topical use of the invention may be either of cosmetic or therapeutical type (dermopharmacy).
  • the present invention proposes a composition comprising a mixture of A- GHK-B tripeptide and A-GQPR-B tetrapeptide (SEQ ID NO: 1), or their derivatives or analogs, for the therapeutic treatment of the papillary dermis.

  • the mixture of the invention will have a healing effect thanks to a papillary dermis reconstruction.
  • the peptides according to the invention may be optically pure, or consist of L or D isomers or a mixture thereof.
  • the L isomers which are those present in nature may be preferred because less expensive.
  • invention peptides may be fragments of a larger peptide, containing more amino acids than the tripeptide and tetrapeptide active "core".
  • the present invention also encompasses derivatives (with modifications and/or addition of a chemical function but no change in the carbon skeleton) and analogs (with modifications and/or addition of a chemical function but in addition a change in the skeleton carbon), complex with other species such as a metal ion (eg copper, zinc, manganese, magnesium, and others).
  • a metal ion eg copper, zinc, manganese, magnesium, and others.
