Description

TECHNICAL FIELD [0001] The present invention relates to a cosmetic or pharmaceutical composition for skin whitening, elasticity, wrinkle improvement, moisturizing or anti-inflammation, inflammation < / RTI >

The present invention relates to a cosmetic composition, a pharmaceutical composition and a health food having excellent effects such as skin whitening, elasticity, wrinkle improvement, moisturizing or anti-inflammation, The present invention also relates to a cosmetic composition, a pharmaceutical composition and a health food which can exert such effects even in a small amount.

It is a common desire to have white skin. The color or brightness of the skin is genetically determined by the concentration and distribution of melanin in the human skin, but is also influenced by environmental or physiological conditions such as sun UV, fatigue or stress. Melanin is produced by a nonenzymatic oxidation reaction of tyrosine, which is a kind of amino acid, by the enzyme tyrosinase, which is converted to DOPA and Dopaquinone. The pathway for the formation of melanin is known, but the mechanism by which the melanin synthesis induces tyrosinase is not yet elucidated.

On the other hand, commonly known whitening ingredients include substances inhibiting the activity of tyrosinase enzymes such as kojic acid or arbutin, hydroquinone, vitamin C (L-ascorbic acid) There are plant extracts. By inhibiting the synthesis of melanin pigment, they can brighten the skin tone to realize skin whitening, and it is possible to improve skin hypercholesterolemia such as stain or freckles due to ultraviolet rays, hormones or heredity. However, when applied to skin, there is a problem that the use amount is limited due to safety problems such as irritation and redness, or the effect is insignificant, so that a practical effect can not be expected.

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.

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. The glycation takes place through a series of chemical reactions known as amarylidation, maillard reaction, resulting 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), which inhibits skin elasticity and promotes wrinkle formation by preventing collagen from forming a proper structure

Also, it is known that the final saccharification product produced by saccharification is a brownish substance and accumulates on the dermal layer as the skin ages. It is believed that as the aging of the skin progresses gradually, the face light turns yellow and it is known that the reflection light reflected from the skin decreases as the specific final saccharification product accumulates. While the amount of melanin pigment in the skin is not related to skin aging, the final glycation product accumulated in the dermal layer of the skin gradually increases in amount as the skin ages, and the skin color becomes dull (Hiroshi, O. et al, Skin Research and Technology, 15, p. 496, 2009)

Aminoguanidine, pyridoxamine, and aspirin are known to inhibit glycation. 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. Kinin, Plasmin or Complement, which are vasoactive polypeptides, have vasodilatation, contraction and chemotaxis action, as well as 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 or indomethacin are non-steroidal drugs used for anti-inflammatory purposes. Prednisolone, a steroid, Or dexamethasone. It is also known that allantoin, azene or hydrocortisone are effective for anti-inflammation. However, these substances have a problem that they can not be expected to effectively reduce the inflammation because of their limited use due to the safety of the skin, have.

Accordingly, it is possible to provide skin whitening, elasticity, wrinkle improvement, moisturizing and anti-inflammatory effects that are superior to living body-safe, effective ingredients, and more effective than those having existing skin whitening, elasticity, wrinkle, moisturizing and anti- It is urgently required to develop a component having an amino acid sequence.

The inflammation is one of biological tissue defense responses to a certain stimulus, and includes three types of tissue degeneration, circulatory disorder and exudate, and tissue proliferation It is a complicated lesion that accompanies. 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.

As can be seen from the results of the above Table 4, the compound of the formula (1) has a better inhibitory effect on melanin formation even when a smaller concentration is applied to cultured rat melanoma cells as compared with arbutin known as a whitening substance , Indicating less total melanin content.

Therefore, it was found that the compound of formula (1) can be used for whitening purposes.

Example  5: Antialcification  effect

In order to confirm the anti-glycation effect, the saccharification inhibitory activity was measured using L-arginine and glucose.

First, dissolve 1 M L-arginine and 1 M glucose in 1 M phosphate buffer (pH 7.4) and dilute the sample to 50 and 100 ppm using 1M phosphate buffer solution. Mix 1 M L-arginine and 1 M phosphate buffer at a ratio of 1: 4, and dispense 80 μl each into 96-well plates. Add 100 μl of 0.01 M aminoguanidine to be used as a positive control and a sample diluted to 50 and 100 ppm, respectively. Mix these samples well and then add glucose diluted in 1 M phosphate buffer to a final concentration of 0.1 M glucose. And reacted at 70 ° C for 4 hours. The degree of saccharification was measured by measuring the absorbance of the 96-well plate at 420 nm using a spectrophotometer.

Glycation in the following formula is an experimental group in which 1M L-arginine and 1M glucose were added to induce glycation. To measure the absorbance of the sample itself, add 1M L-arginine and sample without glucose and measure the absorbance at 420 nm Respectively. The saccharide inhibitory activity can be obtained by the following formula.

The antagonism effect of the compound of formula (1)
