【発明の属する技術分野】
本発明は、メラニン産生促進剤及びチロシナーゼ活性促進剤、並びにこれらを含有する化粧料、皮膚黒化用組成物及び白髪防止用組成物に関する。
【0002】
【従来の技術及び発明が解決しようとする課題】
人の皮膚や毛髪の色調は、皮膚及び毛髪の色素メラニンの量によって決定される。メラニンは、皮膚や毛髪の毛球部に存在する色素細胞(メラノサイト)において、酵素チロシナーゼによってチロシンから生合成されることから、メラノサイトの活性化又はチロシナーゼの活性化により、メラニン産生が亢進すれば、皮膚は褐色化し、毛髪は黒色化する。
【0003】
皮膚においては、シミ、ソバカスの原因の一つとして、皮膚の紫外線暴露による刺激、ホルモンの異常又は遺伝的要素等によって皮膚内に存在するメラノサイトが活性化されメラニン産生が盛んになることが考えられていることから、従来、チロシナーゼの活性を阻害してメラニン産生を抑制したり、産生したメラニンを減少させる美白剤が開発されてきた。しかし、近年の若年層においては、褐色の肌を望む場合も多く、わが国においては日光浴を求めたり屋内での紫外線照射を受けることが流行し、欧米においてはジヒドロキシアセトンを主成分とするセルフタンニング剤が出回っているのが現状である。
【0004】
このような過度の紫外線照射は皮膚に大きなダメージを与え、皮膚癌の発生を招くおそれもあり、またセルフタンニング剤においても、その作用は角層のメイラード反応により皮膚を褐色化させていることから、色合いや安定性及び紫外線防御能の低下を招く等の安全性の面で問題が指摘されている。
【0005】
一方、白髪は、毛母色素細胞の変化によってメラニンが減少する生理的老化現象の一つであるが、その発生機序は未だ解明されていない。従って、白色化した髪を黒髪へと変化させる方法として、白髪を防止又は改善する成分等の報告が数多くなされているものの、いずれも有効性や安全性の点で十分なものは得られておらず、染毛剤による染毛が中心となっているのが現状である。
【0006】
従って、メラノサイトに直接作用してその増殖を高めたり、チロシナーゼの活性を促進することによりメラニン量を増加させる成分を見出されば、本来メラニンが持つ生体防御能を促進させて皮膚のダメージを予防すると共に、肌の褐色化や白髪の防止又は改善が実現できる。
【0007】
本発明の目的は、皮膚及び毛髪のメラニン量を増加し、化粧料、皮膚黒化用組成物及び白髪防止用組成物として有用なメラニン産生促進剤及びチロシナーゼ活性促進剤を提供することにある。

BACKGROUND OF THE INVENTION
The present invention relates to a melanin production promoter and a tyrosinase activity promoter, and a cosmetic, a skin darkening composition and a white hair prevention composition containing these.
[0002]
[Prior art and problems to be solved by the invention]
The color of human skin and hair is determined by the amount of pigment melanin in the skin and hair. Melanin is biosynthesized from tyrosine by the enzyme tyrosinase in pigment cells (melanocytes) present in the hair bulb of the skin and hair, so if melanin production is enhanced by melanocyte activation or tyrosinase activation, Turns brown and the hair turns black.
[0003]
In skin, one of the causes of spots and freckles is that melanocytes present in the skin are activated and stimulated melanin production due to irritation caused by ultraviolet exposure to the skin, hormonal abnormalities or genetic factors. Therefore, conventionally, whitening agents that inhibit the activity of tyrosinase to suppress the production of melanin or reduce the produced melanin have been developed. However, many young people in recent years often want brown skin. In Japan, it is popular to seek sun bathing or receive ultraviolet irradiation indoors. In Europe and the United States, self-tanning agents mainly composed of dihydroxyacetone Is currently on the market.
[0004]
Such excessive UV irradiation may cause serious damage to the skin and may lead to the occurrence of skin cancer. Also in the self-tanning agent, the effect is that the skin is browned by the Maillard reaction of the stratum corneum. However, problems have been pointed out in terms of safety, such as deterioration of hue, stability and UV protection ability.
[0005]
On the other hand, white hair is one of the physiological aging phenomena in which melanin is reduced by changes in hair matrix pigment cells, but the mechanism of its occurrence has not yet been elucidated. Therefore, as a method for changing whitened hair to black hair, although there have been many reports on ingredients for preventing or improving white hair, none of them has been obtained in terms of effectiveness and safety. First of all, it is the current state of hair dyeing with hair dyes.
[0006]
Therefore, if a component that increases the amount of melanin by directly acting on melanocytes and increasing their proliferation or promoting the activity of tyrosinase is found, the body's defense ability inherent to melanin is promoted to prevent skin damage. In addition, it is possible to prevent or improve skin browning and gray hair.
[0007]
An object of the present invention is to provide a melanin production promoter and a tyrosinase activity promoter useful as cosmetics, skin darkening compositions and white hair prevention compositions that increase the amount of melanin in skin and hair.
[0008]
[Means for Solving the Problems]
The present inventors searched for substances that increase the production of melanin in the skin and hair, and a specific dihydrolupeol derivative activated the growth of melanocytes and promoted the activity of tyrosinase, significantly increasing the production of melanin. The present invention was completed by finding that it has an enhancing action and is useful for preventing or improving skin darkening and gray hair.
[0009]
That is, the present invention provides the following general formula (1)
[0010]

After completion of the reaction, the catalyst was removed by filtration, and the filtrate was cooled to room temperature. As a result, colorless needle crystal dihydrololeol was obtained.
[0023]
Example 1 Tyrosinase Activity Promotion Effect Melanocyte cells derived from human caucasian were seeded at 10000 cells / hole in a 96-well plate (0.32 cm 2 ) and cultured at 37 ° C. in a melanocyte growth medium. Several days later, the medium was replaced with a medium supplemented with dihydrolpeol (final concentration 1 μM), and further cultured for 3 days.
After completion of the culture, the culture solution was removed, 100 mM Tris buffer solution, pH 7.2 was added, and the cell membrane was disrupted by leaving it for 30 minutes, and assay buffer (100 mM sodium phosphate pH 7.1, 4% N, N-dimethyl) was added thereto. Formamide) and a final concentration of 1 mM L-dopa and 6 mM MBTH (3-methyl-2-benzothiazoline hydrazone), and reacted at 37 ° C. for 30 minutes. The reaction color of L-dopa and MBTH was measured at an absorbance of 505 nm to determine the tyrosinase activity promotion rate. The results are also shown in Table 1.

Example 2 Promoting Effect of Melanin Production Human melanocytes derived from human Caucasian were seeded at a culture diameter of 22 mm (3.8 cm 2 ) at 100,000 cells / hole and cultured at 37 ° C. in a melanocyte growth medium (containing PMA). Several days later, the medium was replaced with a melanocyte growth medium not containing PMA supplemented with dihydrolupeol (final concentration 1 μM), and further cultured for 4 days. After removing the medium and washing with phosphate buffered saline, a certain amount of 2N NaOH was added, and the cells were lysed by heating at 60 ° C. for 60 minutes, and the absorbance at 405 nm was measured. The amount of melanin was calculated from a calibration curve prepared in advance using a melanin standard product, and the melanin production promotion rate was determined according to the following criteria. The results are also shown in Table 2.
