Summary for Patent: 9,387,235

Title:	Cosmetic preparations containing PTH fragments
Abstract:	A cosmetic or pharmaceutical composition includes a peptide parathyroid hormone fragment, derivatives thereof, salts thereof, and combinations thereof, where the peptide fragment conforms to the structure R1-NH-AA-R2 where R1 is selected from the group consisting of --H, a linear or branched, saturated or unsaturated acyl group having from 1 to 24 carbon atoms optionally functionalized with an --OH, --SH, --COOH or --CONH2 group, or a sterol group which is bonded by a functional group with the peptide; where R2 is --OH, --OH functionalized by a linear or branched, saturated or unsaturated alkyl group having from 1 to 24 carbon atoms, or a sterol group; and where AA corresponds completely or partially to the sequence of amino acids according to SEQ ID No. 1 corresponding to the PTH (28 to 34) region.

Application Number:	11/570,614
Patent Claims:	1. A cosmetic composition for topical application, comprising: a peptide parathyroid hormone fragment, salts thereof, and combinations thereof, wherein the peptide fragment conforms to the structure R1-NH-AA-R2 wherein R1 is an acetyl group; wherein R2 is --OH; wherein AA corresponds to acids 2-5 of SEQ ID NO:1; and wherein the peptide fragment is present in the composition in an amount effective to cosmetically treat intrinsic or extrinsic deterioration of skin or hair when the composition is topically applied. 2. The composition according to claim 1, wherein AA comprises pGlu-Asp-Val-His (SEQ ID NO:2). 3. The composition according to claim 1, wherein His is replaced by an amino acid selected from the group consisting of Leu, Ile, Nle (Norleucine), Met, Val, Ala, Trp, and Phe. 4. The composition according to claim 1, wherein the peptide fragments are obtained by chemical synthesis, enzymatic synthesis, and controlled hydrolysis of natural proteins of micro-organisms, plants or animals which contain the sequence. 5. The composition according to claim 1, wherein the peptide fragment is present in the composition in an amount effective to combat the formation of wrinkles, reduce the impressions left by wrinkles, strengthen the dermis and/or the dermis/epidermis junction (DEJ), reduce the phenomenon of cellulite of the subcutaneous tissues, promote healing, combat the reduction in the number of cells brought about by deterioration (by ageing or extrinsic factors) of human skin, stimulate and/or regenerate capillary re-growth, and/or combat the loss of hair. 6. The composition according to claim 1, wherein the peptide fragment is present in the composition in an amount effective to stimulate production of the protein TGF131 (growth transformation factor), the receptors present at the surface of cells which trigger the biological response to TGFI31, mRNA, maternal proteins, proteins involved in the synthesis of dermo-epidermal junction, and combinations thereof. 7. The composition according to claim 1, wherein the peptide fragment is present in the composition in an amount effective to combat inflammation. 8. The composition according to claim 6, wherein the maternal proteins include collagen, elastin, proteoglycans, and combinations thereof. 9. The composition according to claim 6, wherein the proteins involved in the synthesis of dermo-epidermal junction include perlecan, thrombospondin, nidogen, and integrins. 10. The composition according to claim 1, wherein the peptide fragment is present in the composition in an amount effective to regulate the enzymes involved in the degradation of the extra-cellular matrix, for controlling the expression of TIMPs, and combinations thereof. 11. The composition according to claim 1, wherein the peptide parathyroid hormone fragment, salts thereof, and combinations thereof are used at a concentration of from 0.01 to 1000 ppm. 12. A method for treating a substrate against intrinsic or extrinsic cutaneous deterioration, comprising applying the composition according to claim 1 to a substrate selected from skin, human hair, and combinations thereof. 13. The composition according to claim 1, wherein the peptide fragment is present in the composition in an amount effective to increase growth of dermal fibroblasts, increase expression of genes involved in skin quality, increase lumican expression in dermal fibroblasts, and/or increase expression of collagen type I.
