Description

[0001] The present invention relates to a composition for improving skin condition comprising cau-

More particularly, the present invention relates to a cosmetic composition, a pharmaceutical composition, and a health food, which have excellent effects on antihalation, blackening, wrinkle improvement, elasticity improvement or anti-inflammation of the skin will be.

Due to the economic growth, the interest in the appearance as well as the health is increasing, and the desire to keep skin and keep healthy is also increasing. In recent years, not only healthy skin maintenance but also self-tanning products have been increasingly used to make skin look healthier. Self-tanning can avoid photo-aging due to overexposure to ultraviolet light, and it is possible to produce a tanning effect even in a season when sunlight does not shine. Recently used self-tanning products have been combined with keratin in the stratum corneum, such as Erythrulose and Dihydroxyacetone, to temporarily dye the skin and dye it. However, in the case of dihydroxyacetone, the skin tone is often not uniform according to the usage method, and there is a problem that the skin is smudged due to peeling of the keratin, and the erythrulose is colored with a more uniform skin tone, . In addition, it has been reported that exposure to ultraviolet light within 24 hours after application to the skin promotes active oxygen production of the skin.

In addition, gray hair generally occurs when the age is higher, giving the feeling of old age, and gray hair, especially at a young age, causes stress. White moths are more prominent in Oriental populations with black hair than white ones with bright hair color, and are being studied in health and beauty and psychology. Melanin is divided into red-yellow Pheomelanin and black-brown Eumelanin. Melanin in hair is an important factor that determines the color of hair. Melanin produced in the melanocyte present in the hair, After being transferred to the cortical cell keratinocytes, the hair moves upward with the growth of the hair. The gray hair, recognized as a phenomenon of physiological aging, is caused by a decrease in the number of hair melanocytes and a decrease in the production of melanin due to a decrease in function of melanocytes. Dyeing is currently used as a solution to white moth, but dyeing must be re-pigmented by growth of gray hair in a temporary manner, and the ingredients contained in the dye of the hair dyes become irritants and cause contact dermatitis or skin allergy It is becoming a problem.

Collagen is a major substrate protein produced in the fibroblasts of the skin and exists in extracellular epilepsy. Its important functions are mechanical durability of the skin, resistance of connective tissues and binding force of tissues, support of cell adhesion, cell division and differentiation (Induction of growth of an organism or wound healing) are known. Such collagen is reduced by photoaging by age and ultraviolet irradiation, and collagenase activity, which degrades collagen, promotes collagen reduction. This is known to be closely related to the formation of wrinkles in the skin.

In addition, Elastin fiber forms crosslinks with collagen and is a skin constituent important for wrinkle formation involved in skin elasticity. The deficiency and aggregation of elastin fibers and the marked increase in the activity of the elastin degrading enzyme Elastase have been found to be one of the causes of skin wrinkles. It is known that Elastase is the only enzyme capable of degrading elastin, and its inhibition can fundamentally reduce the wrinkles of the skin.

On the other hand, collagen and elastin fibers are substrate proteins that play an important role in water retention in the dermal layer. These protein proteins adsorb moisture and increase the water holding capacity inside the structure, thereby allowing the skin to maintain proper moisture content. And it is known to be involved in maintaining the elasticity of the skin.

In addition, the elastic fiber produced in the fibroblast of the skin forms a cross-link with collagen, and is a skin constituent important for wrinkle formation which is involved in skin elasticity. Deficiency and decomposition of elastic fibers were found to be one of the main factors of skin wrinkle formation and elasticity reduction.

Presently, retinoids, adenosine, animal placenta-derived proteins, chlorella extract, and the like are known to improve wrinkles. The best known retinol promotes collagen synthesis and inhibits elastase enzymes, but it is unstable. When applied to the skin, it has a limited use due to safety problems such as irritation and redness, and chlorella extract has little effect, It is known that it is difficult to expect a wrinkle-improving effect.

Glycation generally refers to a reaction in which a simple sugar such as glucose or fructose forms a covalent bond to a protein or fat that occurs without involvement of the enzyme. Saccharification takes place through a series of complex chemical reactions known as Amadori rearrangement, Maillard reaction, which results in the formation of advanced glycation endproducts (AGEs).

On the other hand, the glycation process of the protein does not involve the enzymatic action, so it occurs slowly, and as a result, the protein having a longer half-life such as collagen has more influence. Analysis of the final glycation products revealed that the more aged the glycated collagen was accumulated, the accumulation of the final glycated product changed the protein to a harder and more brittle state, and the glycated collagen was found in the extracellular matrix of the dermal layer (Dyer, DG et al. , The Journal of Clinical Investigation, 9, p. 2463, 1993), by inhibiting collagen from forming a proper structure and thereby reducing skin elasticity and promoting wrinkle formation.

Aminoguanidine, pyridoxamine, and aspirin are known to inhibit glycosylation. However, these substances are limited in their use due to the safety of the skin, There is a problem that can not be expected.

Inflammation is the immune response of the body in response to a wound or disease. Oxidative stresses such as ultraviolet rays, active oxygen, and free radicals activate inflammatory factors and cause aging of various diseases and skin. The vasoactive polypeptides Kinin, Plasmin and Complement have vasodilatation, contraction and chemotaxis, and also include lymphokines such as interleukin-6 (IL-6) Phosphorus and arachidonic acid are responsible for inflammation. Arachidonic acid is metabolized through the two pathways of cyclooxygenase or lipoxygenase and is metabolized to inflammation mediator Prostaglandin or Lukotriene to mediate various inflammatory responses.

On the other hand, in order to eliminate inflammation, elimination of inflammation source, reduction of vital reaction and symptoms is called anti-inflammatory. Flutenamic acid, Ibuprofen, Benzydamine, Indomethacin, and Prednisolone have been used for antiinflammatory purposes to date. Nonsteroidal antiinflammatory agents include fluthenic acid, , And dexamethasone. It is also known that allantoin, azene, hydrocortisone, etc. are effective in improving inflammation. However, these substances have problems in that their use is limited due to the safety of the skin, or the effects thereof are insignificant, have.

Accordingly, it is possible to provide a composition which is safe and biologically safe, effective for skin, safe and stable, and has anticalcification, blackening, wrinkle improvement, elasticity improvement, Improvement of elasticity, or development of a component for anti-inflammation is strongly desired.

Accordingly, a problem to be solved by the present invention is to solve the above-mentioned problems, and to provide a new active ingredient which is safe for human body and has little side effects and is excellent in antihalation, blackening, wrinkle improvement, elasticity improvement or anti- To provide useful applications.

In other words, a problem to be solved by the present invention is to provide a composition comprising an active ingredient having excellent efficacy as an active ingredient.

In order to solve the above problems, the present invention provides a composition for blackening, skin elasticity enhancement, skin wrinkle improvement, skin moisturizing or skin antiinflammation for skin or hair containing cau- tatin as an active ingredient, Provides a cosmetic composition, a pharmaceutical composition or a health food.

That is, the present invention provides new uses of cowdatin as a cosmetic composition or a pharmaceutical composition, for blackening skin or hair, for improving skin elasticity, for improving skin wrinkles, for skin moisturizing or for skin anti-inflammation.

The inventors of the present invention have found that cauadin promotes skin collagen production and inhibits the activity of elastase, thereby improving wrinkles and elasticity of the skin, thus completing the present invention. In addition, it was confirmed that the cowdatin increased the total amount of melanin to exhibit the blackening effect of the skin or hair, inhibited the NO production, and showed an anti-inflammatory effect. In addition, cowartin exhibits an antagonism effect, and acts as an auxiliary to improve skin wrinkles and skin elasticity, and can exhibit a synergistic effect.

In the present invention, the term 'blackening effect' means that the coloring matter of the skin or hair is increased, and in particular, the amount of the melanin pigment is increased, which means that the skin or hair shows a dark color. The invention is not limited by this mechanism.

In the present invention, the term 'improving elasticity or skin elasticity' means reducing the degree to which the skin is stuck or stretched. In addition, the elasticity means that elasticity of the skin is maintained in a state where elastin and collagen are sufficiently present.

In the present invention, "improving wrinkles" refers to preventing, suppressing or inhibiting the generation of wrinkles on the skin, or alleviating wrinkles that have already been formed.

In the present invention, the term 'moisturizing or skin moisturizing' means increasing the skin moisture and maintaining a moist state. Skin moisturizing effect can help to improve wrinkles and elasticity of skin.

In the present invention, the term 'anti-inflammatory effect' refers to inhibition of inflammation. The inflammation is one of defensive responses of biological tissues to certain stimuli, and involves three types of tissue degeneration, circulatory disorder, exudate, and tissue proliferation Complex lesions. More specifically, inflammation is part of congenital immunity and, like in other animals, human congenital immunity recognizes a pattern of cell surfaces that are specifically present in a pathogen. Phagocytes recognize cells with such surfaces as non-magnetic and attack pathogens. If pathogens break through the physical barriers of the body, an inflammatory reaction occurs. Inflammation is a nonspecific defense that creates hostile environments for microorganisms entering the wound. In the inflammatory response, white blood cells that are responsible for the early stage of immune response, when wounded or infected, enter the body to express cytokines. Therefore, the expression level of intracellular cytokine is an index of inflammatory response activation. Examples of skin diseases associated with inflammation include atopic dermatitis, psoriasis, radiation, chemical substances, inflammatory diseases caused by burns, acid burns, vesicular dermatosis, visceral type diseases, itching due to allergies, seborrheic eczema, rose acne, Inflammatory hair loss such as pemphigus vulgaris, polymorphous exudative erythema, erythema nodosum, erythematosus, pharyngitis, alopecia areata, skin T-cell lymphoma, and the like.

In the present invention, the 'antagonism' effect means preventing the collagen from being saccharified in the extracellular matrix of the dermal layer, thereby enhancing elasticity of the skin and preventing wrinkle formation. In addition, the anti-glycation effect inhibits the production of a final glycation product accumulated on the dermal layer according to skin aging. Therefore, in the present invention, the anticarcinogenic effect can cause a synergistic effect on skin elasticity enhancement and wrinkle improvement.

In order to solve the above-mentioned problems and to achieve the object of the present invention, the present invention provides a composition comprising a compound represented by the following general formula (1).
