Description

TECHNICAL FIELD The present invention relates to a cosmetic or pharmaceutical composition for skin elasticity, wrinkle improvement, or moisturizing, which comprises a microcrystalline cellulose or a pharmaceutically acceptable salt thereof, and a cosmetic or pharmaceutical composition for skin elasticity, anti-wrinkle or skin moisturizing comprising sophoricoside or a pharmaceutically acceptable salt thereof}

The present invention relates to a cosmetic composition, a pharmaceutical composition and a health food having excellent effects such as elasticity, wrinkle improvement, moisturizing and the like, particularly having excellent effects related to the skin. 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.

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)

Example  One: Collagenase  Activity inhibitory effect

The inhibitory effect of collagenase, an enzyme that degrades collagen, was confirmed as follows.

Collagenase used collagenase derived from rat's interest and N- (3- [2-Furyl] acryloyl) -Leu-Gly-Pro-Ala was used as a collagenase substrate. The buffer solution used was a solution of 50 mM Tricine, 10 mM CaCl ₂ .H ₂ O, 400 mM NaCl (pH 7.5) dissolved therein. The synthetic substrate was dissolved in a buffer solution at a concentration of 10 mM and finally diluted to 75 μM. The collagenase was dissolved at a concentration of 1 unit / ml using cold third distilled water at 4 ° C and then diluted with buffer solution to a final concentration of 0.05 unit / ml. Collagenase inhibition candidates were tested at final concentrations of 25 and 50 ppm. At this time, the positive control group was set to have a final concentration of 50 ppm of epigallocatechin gallate (EGCG) whose collagenase inhibitory effect was known. The reaction was carried out in a 96-well plate and allowed to react at room temperature for 10 minutes. Absorbance was measured at 345 nm using a spectrophotometer at intervals of 1 minute, and the maximum slope of absorbance versus time was determined to determine the activity of the enzyme. Collagenase inhibition rates were calculated as follows.

Inhibition of Collagenase Activity of Compound (1) (Number of Repeats = 3)

That is, the compound of formula (1) exerts excellent collagenase activity inhibitory effect. Therefore, it was found that the compound of Chemical Formula 1 can be used for skin regeneration and wrinkle improvement.

Example  2: Elastase  Active inhibitory effect

The activity inhibitory effect of Elastase, an enzyme that degrades elastin, was confirmed as follows.

Elastase used Elastase from human leukocyte cells and MeOSuc-Ala-Ala-Pro-Val-pNA as synthetic substrate for Elastase. The buffer solution used was 100 mM Tris (pH 7.5) solution. Finally, 0.2 mU was used for the ELASTASES using a buffer solution. In addition, the synthetic substrate of Elastase was diluted with buffer solution to make a final concentration of 0.5 mM by making a 100 mM solution using DMSO. At this time, the positive control group was set to contain 10 ppm of quercetin, which is known as an ELASTIC inhibitor. Ella stase inhibition candidates were added to give a final concentration of 10, 20 ppm. The reaction was carried out in a 96-well plate and allowed to react at room temperature for 20 minutes. Absorbance was measured at 405 nm using a spectrophotometer at intervals of 1 minute, and the slope of absorbance versus time was determined as the activity of the enzyme. Ella stasis inhibition rates were calculated as follows.

Inhibitory effect of the compound of formula (1) on elastase activity (number of repeats = 3)

sample Enzyme activity Inhibition rate (%) The compound of formula (1) (20 ppm) 4.3 58.65 The compound of formula (1) (10 ppm) 9.2 11.54 The positive control (Quercetin, 10 ppm) 3.5 66.35 The control (DMSO, 20 ppm) 10.4 -

As can be seen from the results in Table 2, when the compound of Chemical Formula 1 was treated, it was found that the effect was less than that of the positive control, but the inhibition of the elastase activity was excellent. That is, the compound of formula (1) exerted a superior inhibitory effect on elastase activity. Therefore, it was found that the compound of Chemical Formula 1 can be used for skin regeneration and wrinkle improvement.

Example  3: 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)

sample Inhibition rate (%) The control (DMSO, 50 ppm) - The positive control (Aminoguanidine, 55 ppm) 54.89 The compound of formula (1) (50 ppm) 60.39 The compound of formula (1) (25 ppm) 34.17
