Description

TECHNICAL FIELD The present invention relates to a composition for improving skin condition comprising hematoxylin,

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

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 that inhibit tyrosinase enzyme activities such as kojic acid or arbutin, and also include hydroquinone, L-ascorbic acid or derivatives thereof And various plant extracts are known to have whitening effect. By inhibiting the synthesis of melanin pigment, they can lighten skin tone to realize whitening of skin, and it is possible to improve skin hypercholesterolemia such as stain or freckles due to ultraviolet ray, hormone or oil field. 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.

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.

The fibrillin-1 protein, which is a constituent of elastic fibers, is a type of microfibril that exists outside the cell and is known to function as a skeleton when elastic fibers are formed. Fibrillin acts as an adhesive to help each part of our body bind and maintain. Mutations in the fibrilin-1 gene are caused by the presence of Marfan syndrome, which causes abnormalities in the lungs, skin or skeletal system. It was known to be the cause. Recently, it has been found that fibrilin-1 acts as a reservoir of TGF-beta.

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.

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 weakly 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 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.

Therefore, it is possible to provide a pharmaceutical composition which is safe and biologically safe, effective for skin, safe and high in stability, and exhibits antihalation, whitening, 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 to human body and has little side effects and is excellent in antihalation, whitening, 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.

That is, the present invention relates to the use of hematoxylin or a pharmaceutically or cosmetically acceptable salt thereof as a cosmetic composition or a pharmaceutical composition for skin whitening, skin elasticity enhancement, skin wrinkle improvement, skin moisturizing or skin anti- To provide a new use.

The inventors of the present invention have found that hematoxylin 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, the hematoxylin exhibited a skin whitening effect by reducing the total amount of melanin, and inhibited NO production and also showed an anti-inflammatory effect. In addition, the hematoxylin exhibits an anticarcinogenic effect and acts as an auxiliary agent for skin whitening, skin wrinkles and skin elasticity improvement, and can exhibit a synergistic effect.

In the present invention, the 'whitening effect' refers to not only brightening the skin tone but also improving skin hypercholesterolemia such as stain or freckles due to ultraviolet rays, hormones or heredity. This whitening effect can be achieved, for example, by reducing the total amount of melanin pigment, but the present 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 antihalation effect can help skin whitening by inhibiting the production of final glycation products accumulated on the dermal layer according to skin aging. Therefore, in the present invention, the anticarcinogenic effect can not only enhance skin elasticity and wrinkle but also produce a synergistic effect on skin whitening.

Absorbance was measured at 420 nm by adding 1M L-arginine and sample alone without glucose to measure the absorbance of the sample itself. The saccharide inhibitory activity can be obtained by the following formula.

The antagonism effect of the compound of formula (1)

sample Inhibition rate (%) The control (DMSO, 50 ppm) - The positive control (Aminoguanidine, 55 ppm) 50.39 The compound of formula (1) (50 ppm) 62.12 The compound of formula (1) (25 ppm) 25.88

As can be seen from the results in Table 4, the compound of Chemical Formula 1 was found to be more excellent in antagonism effect as compared with amino guanidine, which is known as an anticarious substance. That is, the compound of formula (I) exhibits an excellent antihyperglycosylation effect, and antihalation effect plays an auxiliary role in skin whitening, skin wrinkle, and elasticity improvement, and a synergistic effect can be expected.

Experimental Example  5: whitening effect - melanin total amount reduction effect

The compound of Chemical Formula 1 was added to the culture solution of mouse B-16 mouse melanoma cells to determine the whitening effect by measuring the total amount of melanin at the cellular level (Lotan R., Lotan D. Cancer Res . 40: 3345-3350, 1980). To evaluate the toxicity of melanoma cells in rats before the experiment, whitening evaluation was performed by selecting a concentration that is not toxic.

The compound of formula (I) was added to the culture medium to a final concentration of 1 ppm or 10 ppm, and the control group, arbutin, was added to the medium to 100 ppm, and treated with B-16 melanoma cells for 3 days.

Cells were then trypsinized, detached from the culture, centrifuged, and then melanin was extracted. The removed cells were incubated with 1 ml of sodium hydroxide solution (1N concentration), boiled for 10 minutes to dissolve melanin, and the absorbance was measured at 400 nm using a spectrophotometer to measure the amount of melanin produced.

The amount of melanin was measured by an absorbance of 1 × 10 ⁶ cells per unit cell, and the total amount of melanin relative to the control group was calculated as an inhibition ratio (%). The results are summarized in Table 5 below.

Reduction of total melanin levels at the cellular level by concentration

sample Melanin production (abs) Inhibition rate (%) Control group (DMSO, 10 ppm) 0.33 - Positive control (arbutin, 100 ppm) 0.241 26.97 The compound of formula (1) (10 ppm) 19.09 16.56 The compound of formula (1) (1 ppm) 0.330 0

As can be seen from the results of Table 5, the compound of Chemical Formula 1 showed a remarkably excellent total amount of melanin reduction even at 10 ppm as compared with the positive control arbutin, and it was found that the compound of the formula 1 can be used for whitening purposes.

Experimental Example  6: Anti-inflammatory effect -NO generation inhibitory effect

In order to confirm the anti-inflammatory effect and the skin trouble relieving effect of the compound of formula (1), nitrite oxide (NO) formation inhibition test was carried out by the GRIESS method using RAW264.7 cell line (ATCC number: CRL-2278).

Specifically, RAW264.7 cells, macrophages of mice, were subcultured several times, placed in 24-well plates at 3 × 10 ⁵ per well, and cultured for 24 hours. Subsequently, the compound of formula (1) was replaced with a diluted cell culture medium at a final concentration of 1, 10 and 100 ppm. At this time, L-NMMA (L-NG-Monomethylarginine), which is an inhibitor of NO production, was treated together as a positive control, and cultured for 30 minutes. Lipopolysaccharide (LPS) . 100 μl of the supernatant was transferred to a 96-well plate, and 100 μl of the GRIESS solution was added thereto at room temperature for 10 minutes, and the absorbance at 540 nm was measured to determine the NO inhibitory effect of the compound of formula (1) Are shown in Table 6 below.

sample NO production inhibition rate (%) Control group (DMSO, 10 ppm) - L-NMMA (positive control, 10 ppm) 41.02 The compound of formula (1) (1 ppm) 10.64 The compound of formula (1) (10 ppm) 13.83 The compound of formula (1) (100 ppm) 38.05

As can be seen from the results of Table 6, the compound of Chemical Formula 1 exhibited a considerable inhibition of NO production as a natural substance when compared with L-NMMA, a representative anti-inflammatory drug substance. Accordingly, it has been confirmed that the compound of formula (1) can be effectively used for improving skin inflammation and skin troubles. In addition, the anti - inflammatory effect acts as an auxiliary to the skin whitening or wrinkle improvement, and a synergistic effect can be expected.
