Definitions
- the present invention relates to cosmetic and / or dermatological preparations which contain special products obtained from DNA as the active ingredient.
- the human skin performs numerous vital functions. With an average surface area of around 2 m 2 in adults, it has an outstanding role as a protective and sensory organ. The task of this organ is to convey and ward off mechanical, thermal, actinic, chemical and biological stimuli. It also has an important role as a regulatory and target organ in human metabolism.
- Cosmetic skin care is primarily to be understood to strengthen or restore the natural function of the skin as a barrier against environmental influences (e.g. dirt, chemicals, microorganisms) and against the loss of the body's own substances (e.g. water, natural fats, electrolytes) and its horny layer to support their natural regeneration capacity in the event of damage.
- environmental influences e.g. dirt, chemicals, microorganisms
- body's own substances e.g. water, natural fats, electrolytes
- the aim of skin care is also to compensate for the loss of fat and water in the skin caused by daily washing. This is especially important when the natural regeneration ability is insufficient.
- skin care products are intended to protect against environmental influences, especially sun and wind, and to delay skin aging.
- cosmetic preparations which mostly contain vitamins, provitamins, various plant extracts and so on as active ingredients.
- reaction products of DNA that also occur in the cell, such as, for example, photodimers, other photoproducts or oxidation products of the nucleotides, nucleosides or nucleobases, as cosmetic active ingredients.
- 8-hydroxypurines such as 8-hydroxy-guanosine (CAS No. 3868-31-3)
- a reaction product formed from DNA under oxidative stress are:
- Carbohydrates or nucleotide chains can represent or different
- Binding sites of the same otherwise unchanged or otherwise modified DNA analogously also other cyclobutane nucleotide dimers also of different nucleotide bases as well as pyrimidine-pyrimidone-6,4-photoproducts:
- R3 and R3 ' independently of one another represent methyl or hydrogen and R4 and R4 ' independently of one another represent the oxygen of a keto group or the double-bonded NH group in an imido group, and R4 'in the photoreaction product represents an amino or hydroxy group, of interest.
- US 5955059 discloses as treatment methods for psoriasis, vitiligo, as a method for preventing light-related skin aging, UV-related dermatoses and also as a method for reducing the susceptibility to skin cancer and UV-related hyperproliferative diseases, the application of an effective amount of DNA fragments with a length from 2 to 200 bases, the DNA fragments being single-stranded, double-stranded or mixtures thereof.
- British patent application 2336157 describes the use of single-stranded DNA fragments, deoxynucleotides, dinucleotides and / or dimers of dinucleotides for the production of medicaments for stimulating the p53 activity of the cells.
- the object of the present invention was therefore to find new cosmetic and / or dermatological active substances which simulate oxidative or photochemical stress in cells and thus stimulate the cell's own repair mechanisms.
- 8-hydroxy-guanosine is used as the 8-hydroxy-purine nucleoside.
