Description

[0001] The present invention relates to a cosmetic or pharmaceutical composition for promoting hair growth comprising trilyrin (cosmetic or pharmaceutical composition for promoting hair growth containing trillin)

The present invention relates to a composition for promoting hair growth, and more particularly, to a cosmetic or pharmaceutical composition for promoting hair growth containing a component that induces new growth or promotion of hair growth.

Hair is an important part of the process of increasing interest in beauty as the age changes. Hair is a thin, exfoliated structure produced from the surface of the skin. It acts as a cushion against external impact, protects the human body from external stimuli such as direct sunlight, cold, friction, danger, and discharges the heavy metals such as arsenic, mercury and zinc harmful to the body to the outside of the body. The side is also being emphasized.

However, many people are complaining of hair loss due to various causes, including dietary changes and increased internal and external stress.

Human hair has about 100,000 to 150,000 hairs, and each hair has a different growth period. The hair growth cycle consists of three stages: the anagen stage where hair grows most actively, the catagen stage where hair starts to degenerate, and the telogen stage where hair growth stops or rests. .

In general, alopecia refers to an increase in the number of abnormal hair loss due to shortening of hair growth rate in the growing period and increased number of hair in the retrogressive or resting period among these cycles.

Male hormones play an important role in the death and elimination of hair follicles. DKK-1 (Dickkopf-related protein 1) plays an important role in hair follicle growth inhibition and death, among the factors expressed in hair follicles by male hormone.

On the other hand, for periodic hair growth, hair follicle regeneration and stem cell activation must be performed, which is known to be caused by the production and activation of Wnt / β-catenin. In addition, DKK-1 mentioned above is known to be an antagonist of Wnt / [beta] -catenin, so that the above signal system is very important for controlling hair growth.

The herbal remedy for the treatment or prevention of alopecia that has been developed so far includes female hormone-based preparations such as minoxidil, finasteride, tricosaccharide, etc. for promoting blood circulation, enhancing hair follicle function, scalp moisturizing and male hormone suppression, (trichosaccharide), etc., but there are many limitations in use due to adverse effects such as sexual dysfunction, possibility of birth of deformed baby, and general hair growth.

Accordingly, the present invention aims to solve the above-mentioned problems, and to provide a new useful use of a new active ingredient, i.e., an active ingredient, which is less harmful to the human body and can act effectively for promoting hair growth or hair growth.

Hereinafter, the present invention will be described in more detail with reference to the following examples. However, the embodiments 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 above-described embodiments. The embodiments of the present invention are provided by way of example to facilitate a specific understanding of the present invention.

Trilin of the present invention was purchased from Shanghai Standard Biotech Co., Ltd.

< Example  1> Triline  Cytotoxicity Assessment

In this example, cell division of Follicle Dermal Papilla (Promocell, Germany) was measured using Cell Counting Kit-8 (Dojindo Lab, USA) for the evaluation of cytotoxicity of trilin.

First, a uniform number of cells were plated on a 96-well plate, stabilized, treated with 10, 20 ug / ml of trilin, and then cultured for additional 48 hours. Thereafter, CCK-8 was treated and the absorbance was measured at 450 nm for 2 hours. The relative cell viability of cells treated with untreated and treated trilin was analyzed as follows. The results are shown in Table 1 below.

Relative cell viability = (compound treated group) / (untreated group) X 100

sample No treatment BIO
1uM Triline
10 [mu] g / ml Triline
20ug / ml Survival rate (%) 100 103 102 98

As shown in Table 1, it can be seen that the number of cells is not largely changed by the treatment with trilin.

< Example  2> Triline Wnt / β- catenin signal pathway  Investigate the activity effect

To investigate the effect of trilin on Wnt / β-catenin signal pathway activation, TOPflash reporter (Millipore, USA) was used. Human dermal papilla cells were inoculated in a 24-well plate at 2 x 10 &lt; ⁵ &gt; / well and cultured for 24 hours. Then, the cells were treated with 10, 20 ug / ml of trilin and then further cultured for 15 hours. , USA) was used to measure the firefly luciferase activity.

In order to accurately measure the activity of luciferase, the activity of each sample was measured three times, and the activity relative to the control group was calculated as an increase rate (%). The control group is untreated group. The positive control was 6-bromoindirubin-3'-oxime (BIO) and is known to inhibit GSK-3 in the Wnt signaling pathway.

sample Control group BIO
1uM Triline
10 [mu] g / ml Triline
20ug / ml Growth rate (%) 100 152 142 309

As shown in Table 2, the present inventors found that trylline increased TOPflash reporter activity in a concentration-dependent manner, and was selective for Wnt / β-catenin signal transduction and had excellent bowing performance. The measurements corrected firefly luciferase levels to renilla luciferase levels.

< Example  3> DHT Induced by DKK -1 inhibition effect investigation

Activation of Wnt / β-catenin promotes hair growth while male hormone or dihydrotestosterone (WAKO, Japan) acts as an antagonist of Wnt / β-catenin through the promotion of DKK-1 gene expression.

Therefore, in order to investigate whether trilin inhibits DKK-1 gene, which is an antagonist of Wnt / β-catenin, to promote hair growth, human dermal papilla cells were treated with 20 ug / ml of trilin and 100 nM of dihydrotestosterone for 24 hours, The expression of DKK-1 was confirmed by reverse transcription-polymerase chain reaction (RT-PCR) using primers (Bioneer, Korea) shown in Table 3 below. The primers used at this time are shown in Table 3.

Standing column Forward TGATGAGTACTGCGCTAGTC Reverse CTCCTATGCTTGGTACACAC

As a result of the experiment, it was found that the treatment with triline significantly reduced the expression of DKK-1, which was increased by the treatment with dihydrotestosterone, thereby promoting hair growth. The results were analyzed by using a comparative CT (ΔΔCT) Experiment (Livak KJ, Schmittgen TD: Analysis of relative gene expression data using real-time quantitative PCR and the 2-Delta Delta C (T) (2001)). Internal control was performed using GAPDH, and the results are shown in FIG.
