Abstract
Description
[Technical field]
[0001] The present invention relates to a composition for inhibiting the occurrence of gray hair, which has an excellent effect of inhibiting the occurrence of gray hair, and uses thereof. [Background technology]
[0002] Gray hair occurs due to aging of the scalp. Gray hair includes canities and hair graying. Depending on the extent of gray hair, the person with gray hair may appear older than their actual age. Changes in hair color can be recognized as a sign of aging, and the appearance of gray hair that is not appropriate for one's age can act as stress for an individual and have a negative impact on self-esteem. Therefore, various research and development efforts in cosmetics are being conducted to improve gray hair.
[0003] Although hair dyeing is a method for preventing gray hair, the effect of hair dyeing is temporary because gray hair continues to grow as hair grows. Therefore, this method has a disadvantage that hair must be dyed periodically. In addition, conventional oxidative hair dyes may damage the scalp and skin. In addition, black soybean or Houttuynia cordata extracts are used to prevent gray hair, but the effect is difficult to feel.
[0004] The main cause of gray hair is the disappearance of melanocyte stem cells (MSCs) or a decrease in the physiological activity of melanocytes. This reduces the amount of melanin produced by melanocytes in the matrix of hair, eyebrows, and eyelashes, causing the hair to turn white or gray. The melanin produced by melanocytes is transferred to keratinocytes to produce pigmented head hair or body hair. If melanin cannot move to keratinocytes, the hair will lack pigment and gray hair will occur.
[0005] The amount and relative ratio of eumelanin, which is brown and black, and pheomelanin, which is yellow and red, greatly affect the color of hair and body hair. Three enzymes, tyrosinase, DHICA oxidase (TRP-1), and DOPAchrome tautomerase (TRP-2), are involved in the production of melanin, and the activity of these enzymes is known to affect the synthesis of melanin. In this process, tyrosinase catalyzes the oxidation of tyrosine to DOPA and the oxidation of DOPA to dopaquinone. This substance, known as L-dopaquinone or o-dopaquinone, is the precursor of melanin. In the presence of cysteine, dopaquinone spontaneously cyclizes to dopachrome, which is tautomerized to DHICA by dopachrome tautomerase (TRP-2). TRP-1 oxidizes DHICA to form a quinone derivative.
[0006] Among these enzymes, tyrosinase and TRP-1 are expressed in melanocytes around the hair bulb and dermal papilla during the anagen phase of the hair follicle growth cycle, but are not expressed during the catagen and telogen phases.
[0007] As mentioned above, gray hair is affected by both melanocytes and melanocyte stem cells. Also, as melanocytes decrease, melanin production gradually decreases and melanin transmission decreases. This decrease in melanin can manifest as pigmentation disorders in the skin. A representative example of a pigmentation disorder is vitiligo, and one of the causes of vitiligo is the decrease or destruction of melanocytes. Activation of the Wnt / β-catenin pathway has been extensively studied as a method for treating vitiligo (Journal of Investigative Dermatology (2015) 135, 2921-2923). It has also been reported that activating the Wnt signaling mechanism in melanocyte stem cells increases pigment production in hair and epidermal melanocytes (Cell, Vol 145, Issue 6, 10, (2011), pp. 941-955; Medical Research Review (2016), Vol 37, issue 4, 907-945).

[0027] [Figure 1] These are experimental results confirming that escin increased melanin synthesis in B-16 melanoma cells. [Diagram 2] 1 is a graph showing an increase in melanin synthesis depending on escin and its content. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0028] The present invention will be described in detail below with reference to examples to aid in understanding the present invention. However, the examples according to the present invention can be modified into various other forms, and the scope of the present invention should not be construed as being limited to the following examples. The examples of the present invention are provided to more completely explain the present invention to those with average knowledge in the art.
[0029] Experimental Example 1: Increased effect of Wnt / β-catenin signal transduction In this experiment, TCF / LEF Responsive Luciferase Reporter HEK293A stable cell line (Wnt Reporter HEK293A cell; WRHEK293A) was used to confirm the activation of the Wnt / β-catenin pathway. The stable cell line was maintained by subculture using MEM (Corning, USA) and fetal bovine serum (Gibco BRL, Gaithersburg, MD, USA). For the transcription activation assay, 30,000 cells were seeded per well in a 96-well plate and then cultured in an incubator at 37°C for 24 hours. The cells were treated with escin, 27-deoxyactin, ricionotin, nitidine chloride, lanosterol, engeletin, specnuezenide, praeruptorin B, rotunic acid, sesamosid, polygalacin D, momordin Ic, valechlorin, tusilagon, periplosin, porphyrin VII, and platycodin D2 according to the present invention, as shown in Table 1. After culturing for 24 hours, reporter assay was performed using a Luciferase assay system (Promega). Luminescence was measured using a Victor multiwall plate reader (PerkinElmer, USA) according to the manufacturer's experimental method. To confirm the cytotoxicity caused by the substance treatment, the fluorescence expression of GFP was measured in parallel as an internal control. The luminescence value from the luciferase reaction was divided by the GFP fluorescence value, and the value of the untreated control group was set to 100%, and the corresponding values of the treated groups were calculated and expressed as a percentage (%) (Table 1).
[0030] [Table 1]
[0031] Experimental example 2: Confirmation of melanin production effect In this experiment, the compound of Experimental Example 1, which shows an effect of increasing Wnt signaling, was added to the culture medium of B-16 mouse melanoma cells to examine the melanin production effect at the cellular level (Lotan R., Lotan D. Cancer Res. 40: 3345-3350, 1980). Before the experiment, the toxicity of B-16 melanoma cells was evaluated, and a non-toxic concentration was selected to evaluate melanin production. B-16 melanoma cells were subcultured in DMEM (Gibco BRL, Gaithersburg, MD, USA) containing 10% FBS. After that, for melanin synthesis and extraction, the cells were seeded on a 100 mm cell culture dish, and treated with the compound when the confluency was 70%. The compound was treated in the culture medium at a concentration of 10 μg / mL. Alpha-melanocyte stimulating hormone (alpha-MSH) was used as a control. It was added to the culture medium at 10 nM, and then each was treated with B-16 molanomas and cultured for 48 hours. The cells were then trypsinized to remove them from the culture vessel, and centrifuged to extract melanin. The removed cells were added with 1 mL of sodium hydroxide solution (1N concentration) and boiled for 10 minutes to dissolve the melanin. The absorbance was measured at 400 nM using a spectrophotometer to measure the amount of melanin produced. The amount of melanin was quantified in μg / mL units using a standard absorbance curve according to the concentration of melanin. The untreated control group was set as 100%, and the values of the treated groups were calculated relative to this and expressed as a percentage (%) (Table 2).
[0032] [Table 2]
[0033] The melanin synthesis results of escin among the above compounds are shown in FIG. 1 and FIG.
[0034] Experimental Example 3: Test to confirm the effect of the composition 1 for inhibiting gray hair (hair tonic) in inhibiting the occurrence of gray hair A composition 1 (hair tonic) for inhibiting gray hair containing escin and 27-deoxyactein among the compounds of the present invention was prepared. The composition was used to test the effect of reducing gray hair in human hair. Sixty healthy adults with gray hair were divided into five groups of 12 people each, and Comparative Example 1, Example 1, Example 1-2, Example 2, or Example 2-2 was applied to the scalp seven times a week for six months. After use, the degree of gray hair occurrence was evaluated using a Folliscope phototrichogram in comparison with before application of the composition. The experimental results are shown in Table 3, with the values before application taken as 100%.
