Definitions
- the present invention relates to synthetic peptides that regulate fibrinogenesis and cosmetic or dermopharmaceutical compositions containing said peptides useful in the treatment of the skin, preferably for the treatment of those skin conditions that require a regulation of fibrinogenesis such as treatment of aged skin (either intrinsic aging due to the passage of time and genetic factors, or extrinsic due to prolonged exposure to the sun and / or environmental pollutants such as ultraviolet (UV) radiation from sunlight, chemical contaminants, smoke of cigarettes and pollution), or as adjuvants in healing processes to soften the appearance of scars.
- UV ultraviolet
- the skin is composed of two layers: the epidermis and the dermis.
- the outermost layer is the epidermis, which is mainly composed of keratinocytes, melanocytes and Langerhans cells, and its basic function is to retain water from the body, act as a barrier mechanism against harmful chemical agents as well as against pathogenic organisms and carry Out the cell renewal processes.
- the innermost layer, the dermis, formed by fibroblasts, adipocytes and macrophages, is strongly linked to the epidermis through the basement membrane, and contains numerous nerve endings that provide sensations of touch and temperature. It also houses the hair follicles, sweat glands, sebaceous glands, apocrine glands and blood vessels, and one of its main functions is to maintain the elasticity and appearance of the skin.
- extracellular matrix In the dermis is also the extracellular matrix, formed by a set of extracellular proteins (fibrous proteins, glycoproteins and proteoglycans) whose key function is to maintain the structure of the skin, and the proper functioning and development of tissues depends on that its training and regulation is correct [Wiberg C, Klatt AR, Wagener R., Paulsson M., Bateman JF, Heinegard D. and Morgelin M. (2003) "Complexes of matrilin-1 and biglycan or decorin connect collagen Vl microfibrils to both collagen Il and aggrecan" J . BIoI. Chem. 278, 37698-37704].
- extracellular proteins fibrous proteins, glycoproteins and proteoglycans
- the two most important fibrous proteins of the extracellular matrix are collagen and elastin, responsible for the mechanical properties of the tissues, such as the ability to resist tension, compression, extensibility and torsion.
- Proteoglycans have a structural and metabolic function, while glycoproteins, together with proteoglycans, serve as bridges between the components of the matrix and cells [Aumailley M. and Gayraud B. (1998) "Structure and biological! Activity of the extracellular matr ⁇ x "J. Mol. Med. 76, 253-265; Culav EM, Clark CH. and Merrilees MJ. (1999) "Connective tissues: matr ⁇ x composition and its relevance to physical therapy” Phys. Ther. 79, 308-319; Scott JE (2003) "Elasticity in extracellular matrices 'shape modules' of tendon, cartilage, etc. A sliding proteoglycanning model" J. Physiol. 553, 335-343].
- the collagens are a family of extracellular matrix fibrous proteins that constitute 25% of the total protein mass in mammals. They have been classified in more than 20 families, all with individual characteristics that fulfill specific functions in different tissues.
- the main characteristic of collagen is its helical structure formed by association of three polypeptide chains, rich in glycine and proline. Alterations in its amino acid composition cause dysfunction and loss of its mechanical properties [Culav EM, Clark CH. and Merrilees MJ. (1999) "Connective tissues: matr ⁇ x composition and its relevance to physical therapy” Phys. Ther. 79, 308-319].
- These polypeptide chains can be associated with each other forming the fibrils, which have a diameter of 10-300 nm and a length of up to several hundred micrometers in mature tissues. These fibrils often aggregate into larger structures, such as cable bundles, which can be seen by electron microscopy as collagen fibers several micrometers in diameter.
- fibrilogenesis This process is known as fibrilogenesis [Aumailley M. and Gayraud B. (1998) "Structure and biological / activity of the extracellular matrix” J. Mol. Med. 76, 253-265]. Not all collagens have the ability to form fibrils; only type I, II, III, V and Xl collagens, which are known as fibrillar collagens. The dermis of an adult is basically formed by fibrillar collagen type I (80-90%), III, and V. Generally, type I collagen fibers have a larger diameter, a characteristic that correlates with their ability to withstand a greater mechanical load.
- Type III collagen plays a role in tissue extensibility, and over the years it is replaced by type I collagen molecules, a process partially responsible for mature skins being less extensible than infant ones.
- Type V collagen is associated with type I and III by regulating the diameter of the fibrils ['The Biology of the Skin ", Freinkel RK and Woodley DJ., Eds. The Parthenon Publishing Group, 2001; C ⁇ lav EM, Clark CH . and Merrilees MJ. (1999) "Connective tissues: matrix composition and / te relevance to physical therapy” Phys. Ther. 79, 308-319].
- the damage to the collagen architecture can lead to the deposition of disorganized collagen during repair processes, as in the processes of liver cirrhosis, pulmonary fibrosis or dermal scar formation.
- the regulation of the organization of collagen can be potentially useful not only for cosmetic or dermopharmaceutical treatments but also for treating various clinical conditions.
- Proteoglycans constitute one of the major components of the extracellular matrix and are characterized by having a protein heart covalently linked to carbohydrates called glycosaminoglycans (GAGs). They are involved in many of the cellular processes that take place through molecular interactions on the surface of the cells, such as extracellular matrix-cell, cell-cell and receptor-ligand interactions, since they avidly bind to proteins, and are very abundant in these regions [Perrimon N. and Bernfield M. (2001) "Cellular functions of proteoglycans- an overview "Semin. CeII Dev. Biol. 12, 65-67].
- GAGs glycosaminoglycans
- Proteoglycans act as tissue organizers, facilitate cell growth and maturation of specialized tissues, play a fundamental role as biological filters and regulate the activity of growth factors [lozzo RV (1998) "Matrix proteoglycans: from molecular design to cellular function” Annu. Rev. Biochem. 67, 609-652; Ruoslahti E. (1989) "Proteoglycans in cell regulation” J. Biol. Chem. 264, 13369-13372].
- GAGs are polymers formed by repetitions of disaccharides, usually an acetylated amino sugar ( ⁇ / -acetylglucosamine or ⁇ / -acetylgalactosamine) alternating with uric acid (glucuronate or iduronate), and have a high index of sulfate groups, except hyaluronic acid. Due to their richness in acidic groups, they are negatively charged and tend to attract cations such as Na + and, being osmotically active, attract water and allow to maintain tissue hydration.
- GAGs The most common GAGs are hyaluronic acid, chondroitinsulfate, dermatan sulfate, heparan sulfate and queratan sulfate [Sugahara K. and Kitagawa H. (2000) "Recent advances in the study of the biosynthesis and functions of sulfated glycosaminoglycans" Curr. Opin. Struct. Biol. 10, 518-527; Zamfir A., Seidler DG, Kresse H. and Peter-Katalinic J. (2003) "Str ⁇ ctural investigation of chondroitin / dermatan sulfated oligosaccharides from human skin fibroblast decorin" Glycobiology 13, 733-742].
- proteoglycans are the so-called “leucine-rich proteoglycans", which do not exhibit interaction with hyaluronic acid, and which are involved in the structuring of extracellular matrices, in the modulation of the activity of growth factors as well as in the regulation of cell growth properties [lozzo RV (1997) 'The family of the small leucine-rich proteoglycans: key regulators of matrix assembly and cellular growth "Crit. Rev. Biochem. Mol. Biol. 32, 141-174].
- the biglican is found in differentiating keratinocytes in the epidermis and in the vascular endothelium [Bianco P., Fisher LW., Yo ⁇ ng MF, Termine JD and Robey PG (1990) "Expression and localization of the two small proteoglycans biglycan and decorin in developing human skeletal and non-skeletal tissues" J. Histochem. Cytochem.
- Decorin is considered one of the key proteoglycans in the regulation of the structuring and function of many of the elements of the extracellular matrix.
- Decorin binds to growth factors, including proliferation transformation beta factor (TGF- ⁇ ), to other proteins of the extracellular matrix such as fibronectin and thrombospondin, to cell membrane receptors (endocytosis receptor of decorin ), and can also directly interfere with the cell cycle through the induction of p21, a potent inhibitor of cyclin-dependent kinases (CDKs) [Stander M., Naumann U., Wick W. and Weller M. (1999) 'Transforming growth factor-beta and p-21: multiple molecular targets of decorin-mediated suppression of neoplastic growth "CeII Tissue Res. 296, 221-227].
- CDKs cyclin-dependent kinases
- Decorin binds to two adjacent parallel molecules of collagen of the fibril, helping to stabilize The fibril and orienting the fibrinogenesis, being attached to the surface of the collagen fibrils, the lateral interaction between the triple collagen helices becomes more difficult, since it acts as a spacer, and the diameter of the fibrils decreases, thus controlling the dimensions of the fibrils, in particular the uniformity of their diameter and the regular distance between them, thus allowing it to maintain the shape of the tissue / Te ⁇ n / R., Viola M., Welser F., Sini P., Giudici C, Rossi A . and Tira ME (2002) "Interaction of decorin with CNBr peptides from collagens I and II.
- transgenic animals also exhibit increased collagen degradation, which contributes to the poor quality of their skin [Schaefer L, Macakova K, Raslik I., Micegova M., Gr ⁇ ne HJ., Schonherr E., Robenek H., Echtermeyer FG, Grássel S., Bruckner P., Schaefer RM, lozzo RV and Kresse H. (2002) "Absence of decorin adversely influences tubulointerstitial fibrosis of the obstructed kidney by enhanced apoptosis and increased inflammatory reaction" Am. J. Pathol. 160, 1181-1191].
- Babies' skin is smooth and soft, with a thick layer of fat and a very thin protective layer of keratin, while the skin of the elderly is very thin and has many wrinkles, with a very small layer of fat.
- the extracellular matrix also undergoes changes with age, and these contribute to the set of changes in the physical properties of Aging-related skin [Wiberg C, Klatt AR, Wagener R., Paulsson M., Bateman JF, Heinegard D. and Morgelin M. (2003) "Complexes of matrilin- 1 and biglycan or decorin connect collagen Vl microfibrils to both collagen Il and aggrecan "J.
- the cosmetic industry has made significant efforts to counteract this loss of the functionality of the components of the extracellular matrix with age.
- the balance between the production and the degradation of essential biomolecules of the skin is decanted with aging towards the degradation processes, and this leads to a progressive thinning and disorganization of the dermis that causes a flaccidity in the dermis with the consequent wrinkle formation.
- the collagen of the aged skins both chronologically - mature skin - and by prolonged exposure to the sun or environmental pollutants
- the dermal extracellular matrix also contains proteoglycans that are involved in the properties of tissues and that are altered with aging.
- decorin is catabolized into a fragment known as decorunt, which corresponds to a version of decorin to Ia that the carboxy-terminal fragment is missing.
- the skins of fetal origin do not show detectable levels of decorunt, while the maximum levels of decorunt are determined from the age of 30, which is the age from which the signs of aging begin to manifest.
- decorin influences the processes of fibrinogenesis of the collagen and regulates the diameter of the fibrils
- the appearance of decorunt can have an important effect on the elasticity and morphological differences between the collagen fibers of young skins and those of aged skins [ Canino DA, Sorrell JM and Captan AA. (2000) "Age-related changes in the proteoglycans of human skin” Arch. Biochem. Biophys 373, 91-101].
- decorin synthesis is diminished in skin aged by prolonged exposure to the sun or environmental contaminants [Bernstein EF, Fisher LW., Li K., LeBaron RG, Tan EM. and Uitto J.
- Wound healing in adults is a complicated reparative process.
- the healing process begins with the recruitment of a variety of specialized cells for transfer to the site of the wound, and involves the deposition of extracellular matrix and basement membrane, angiogenesis, selective protease activity and reepithelialization.
- An important component of the healing process in adult mammals is the stimulation of fibroblasts to generate the extracellular matrix.
- This matrix Extracellular is a main component of connective tissue that develops to repair the area of the wound.
- a scar is an abnormal morphological structure resulting from a previous injury or injury (such as an incision, excision or trauma) and consists of a connective tissue, which is predominantly a matrix of collagen types I and III and fibronectin .
- the scar consists of collagen fibers in an abnormal organization as well as an excess deposition of collagen.
- mammals when the scar rises on the skin, presenting a bulky appearance, it is because they contain excessly arranged collagen irregularly, and are classified as hypertrophic scars.
- a keloid is another form of pathological healing that not only remains elevated on the surface of the skin, but also extends beyond the limits of the original lesion, and also has an excessive amount of connective tissue that is organized so abnormally forming predominantly vortex bands of collagen tissue.
- An analysis of decorin content in hypertrophic scars shows that the concentration of this is only 25% of that found in healthy tissues [Scott P.G., Dodd C.M., Ghahary A., Shen J. and Tredget E.E. (1998) "Fibroblasts from post-burn hypertrophic scar tissue synthesize less decorin than normal dermal fibroblasts" Clin. ScL (Lond). 94, 541-547), a fact that explains the irregular organization of the collagen present in hypertrophic scars.
- cosmetic or dermopharmaceutical compositions containing molecules that mimic the activity of decorin interacting with the fibrils or collagen fibers, regulating the fibrinogenesis process are potential candidates for use as anti-aging products in order to increase The elasticity, firmness, structuring and flexibility of the skin, or as adjuvants in post-surgical treatments in order to soften the appearance of the scars.
- the applicant of the present invention has determined that the synthetic peptides of the invention are effective in the regulation of fibrinogenesis, thus mimicking the function of decorin.
- the sequence of the peptides of the invention is not contained in the native sequence of the decorin, so that they can be considered as mimetic peptides of the activity of the decorin. It has been postulated in the literature that for its binding to collagen, and consequently the regulation of fibrinogenesis, the peptide sequences must have four amino acids with a pattern of charges [+, -, 0, +] [Scott JE (1996) "Proteodermatan and proteokeratan sulfate (decorin, lumican / fibromodulin) proteins are horseshoe shaped.
- the patent RU2,181,728 describes a synthetic 10 amino acid peptide linked by a disulfide bridge to a 12 amino acid peptide that has a sequence that encompasses the sequence Lys-Glu-Leu-Cit, which is based on the interleukin-8 molecule and stimulates Ia neutrophil migration.
- said peptide meets the load pattern [+, - > u] and has a contiguous citrulline residue, it is not included within the family of the peptides of the present invention, since it has a total of 22 amino acids .
- said patent does not give any indication or suggest that the peptide described is capable of inhibiting fibrinogenesis.
- citrulline is a necessary residue for the regulation of fibrinogenesis, so that an expert in the field could not deduce the nature of the peptides that regulate fibrinogenesis.
- the peptides of the present invention may be useful in the treatment of those skin conditions that require regulation of fibrinogenesis, such as the treatment of aged skin (either due to the passage of age or exposure to sun and / or environmental pollutants) or as adjuvants in healing processes to soften the appearance of scars.
