Collagen is a major substrate protein produced in fibroblasts of the skin and exists in extracellular epilepsy. Its important functions are mechanical rigidity of skin, resistance of connective tissues and binding force of tissues, support of cell adhesion, division of cells and differentiation Growth or wound healing) are known. Such collagen is reduced by aging and photo aging caused by ultraviolet irradiation, which is known to be closely related to the wrinkling of the skin. Also, in recent years, extensive research on skin aging has developed, and important functions of collagen in skin have been revealed.

Effective ingredients promoting collagen synthesis and exhibiting wrinkle-reducing effects are known. For example, retinoic acid, transforming growth factor (TGF), animal placenta-derived protein, betulinic acid, and chlorella extract are known as collagen synthesis promoting substances. However, the above-mentioned effective ingredients are limited in the use amount due to safety problems such as irritation and redness when applied to the skin, or have insufficient effect, so that the effect of improving the skin function by promoting the collagen synthesis of the skin can not be expected.

On the other hand, active oxygen introduced from the outside of the living body or generated in the living body causes many problems such as promoting aging of the living body, cancer, and the like. Therefore, the development and research of antioxidants that inhibit oxidation by active oxygen have been performed. Antioxidants are widely distributed in copper and plants. Many phenolic compounds, flavonoids, tocopherols, vitamin C and selenium are known in fruits and vegetables. However, the antioxidant substances present in nature can not be expected to have practically sufficient effects in skin application. Therefore, although synthetic antioxidants having excellent antioxidant ability and low cost are widely used, their use is restricted due to safety concerns such as human side effects.

In addition, it is the desire of everyone to have a whiter skin. It is genetically determined by the concentration and distribution of melanin in human skin, but is also influenced by environmental or physiological conditions such as sunlight, fatigue, and stress. Melanin is produced by a nonenzymatic oxidation reaction after tyrosine tyrosine, which is an amino acid, is converted to DOPA or dopaquinone by an enzyme called tyrosinase. Thus, the pathway through which melanin is made is known, but the mechanism by which melanin synthesis, the previous step in which tyrosinase acts, is not yet elucidated.

On the other hand, commonly known whitening ingredients include substances inhibiting tyrosinase enzyme activity such as kojic acid and arbutin, hydroquinone, vitamin C (L-ascorbic acid), derivatives thereof, 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.

Therefore, there is a desperate need for development of ingredients having skin regeneration, wrinkle improvement, antioxidative and whitening activity, which are more safe than the living body, have a stable active ingredient, and are more effective than the substances having existing skin regeneration, wrinkle improvement, antioxidant and whitening effect Is desired.

Accordingly, the present invention is to solve the above-mentioned problems, and to provide such a useful use of a new active ingredient, i.e., an active ingredient, which is safe to human body and has good skin regeneration, wrinkle improvement, antioxidant and whitening effect.

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

The synthesized collagen was quantitated using a PICP EIA kit (Procollagen Type I C-Peptide Enzyme Immunoassay Kit). To evaluate the cytotoxicity of human fibroblasts before experimentation at concentrations of 10 ppm, 1 ppm, 0.1 ppm, 0.01 ppm, and 0.001 ppm of the test substance (method for MTT test by culturing fibroblasts [Reference: Mossman T. ), And the collagen aggregation performance was evaluated by selecting the concentration without cytotoxicity. In addition, the cytotoxicity assay was performed by using the Rapid Colorimetric Assay for Cellular Growth & Survival.

In the experiment, the final concentration of the substance of Chemical Formula 1 was set to 1 ppm and 10 ppm, and each sample was added to the culture medium of human fibroblasts and cultured for 2 days. Then, the culture broth was taken and the collagen synthesis Was measured at 450 nm using a spectrophotometer. For the comparison of the effects, the degree of collagen synthesis was measured by the same method for the culture medium of fibroblasts (control group) to which nothing had been added and the sample added with vitamin C to a final concentration of 52.8 / / ml. The amount of collagen production was measured as the UV absorbance, and the increase rate of collagen production was calculated as a relative ratio of collagen production to the control. The results are summarized in Table 1 below.

Collagen biosynthesis effect of the substance of formula (1) (number of repeats = 3) sample Absorbance average Collagen growth rate (%) The substance of formula (1)
1 ppm 512 121.0 The substance of formula (1)
10 ppm 823 194.6 Control group
(No additives) 423 - Vitamin C
52.8 / / ml 519 122.7

To evaluate the cytotoxicity of human fibroblasts before experimentation at concentrations of 10 ppm, 1 ppm, 0.1 ppm, 0.01 ppm, and 0.001 ppm of the test substance (method for MTT test by culturing fibroblasts [Reference: Mossman T. ) Rapid Colorimetric Assay for Cellular Growth & Survival: Application to proliferation & cytotoxicity assays. Journal of Immunological Methods 65, 55-63]. Collagenase assay was performed by selecting concentrations without cytotoxicity.

Human normal skin cells, fibroblasts, were inoculated into 24-well microplates at 2.5 × 10 ⁴ cells per well, cultured in 10% serum DMEM medium and 37 ° C. for 24 hours, and 10% serum DMEM medium was removed The cells were washed once with phosphate buffer solution, and then cultured for 30 minutes in serum-free DMEM medium supplemented with the substance of formula (1) and in serum-free DMEM medium containing no substance of formula (1) for 30 minutes.

After 30 minutes of sample treatment, the cells were cultured for 24 hours after stimulation with 50 ng / ml TNF-α (tumor necrosis factor-α), a substance known to produce MMP-1. The TNF-α-treated group and the treated group were treated with TNF-α and TNF-α, respectively, in the control group without the compound of formula (1).

The supernatant of each well was collected and the amount (ng / ml) of the newly synthesized MMP-1 was measured using an MMP-1 assay kit (Amersham, USA). The inhibition rate of collagenase activity was determined by MMP -1 production inhibition rate (%) was calculated, and the results are shown in Table 2 below.

The amount of MMP-1 in the control group means the amount of MMP-1 in the TNF-a treatment group, and the amount of MMP-1 in the test group means the group to which the substance is added at each concentration.

[Equation 1]

Inhibitory effect on collagenase activity of the substance of formula (1) (number of repeats = 4) sample The amount of MMP-1 (ng / ml) Inhibition rate (%) 10 ppm < tb > 7.15 58.65% 1 ppm of the substance of formula 12.43 28.11% Negative control (TNF alpha no treatment) 6.42 The positive control (TNF a treatment) 17.29
