Description

本発明は、色素細胞におけるメラニン生成を促進して白髪の発生を防止改善することができる白髪防止剤に関する。   The present invention relates to a gray hair preventing agent that can promote the generation of melanin in pigment cells to prevent and improve the generation of gray hair.

白髪の増加は、男女を問わず、美容上大きな問題であるが、これに対する対応手段としては染毛が主である。しかし、近年、色素細胞におけるメラニン生成を促進させる成分が見出され、白髪防止剤として有用であることが報告されている。そのような白髪防止剤としては、cAMP増加剤とプロテインキナーゼC阻害剤とを配合した白髪防止黒化剤(特許文献1)、スギナ、スイカズラ、ヒキオコシ、ブドウ、ヘチマ、セイヨウニワトコ、ブッチャーブハーム、タイソウ、キンギンカ等の植物抽出物を含有する毛髪防止剤(特許文献2、3、4)、シメジ科、ハリタケ科等の担子菌の培養液を配合した頭髪料(特許文献5)等が報告されている。   The increase in gray hair is a major cosmetic problem regardless of gender, but the main means of dealing with this is hair dyeing. However, in recent years, a component that promotes melanin production in pigment cells has been found and reported to be useful as a gray hair preventing agent. As such a gray hair preventive agent, a black hair preventive blackening agent (Patent Document 1) containing a cAMP increasing agent and a protein kinase C inhibitor, Japanese horsetail, honeysuckle, baboon, grape, loofah, elderberry, butcher bucharm, An anti-hair agent containing plant extracts such as Taisou and goldfish (Patent Documents 2, 3, and 4), a hair material (Patent Document 5) and the like containing a culture solution of basidiomycetes such as shimeji mushrooms and agaricaceae are reported. ing.

実施例1
(1)細胞調製:試験はB16F0メラノーマ(B16F0)細胞の組織培養系を用いた。B16F0メラノーマ細胞はATCC(American Type Culture Collection:カタログNo.CRL−6322)より購入し、10%牛胎児血清及び抗生物質を含むダルベッコ改変イーグル培地(Dulbecco’s Modified Eagle Medium:DMEM: シグマ社製)で維持・継代しているものを用いた。
Example 1
(1) Cell preparation: The test used a tissue culture system of B16F0 melanoma (B16F0) cells. B16F0 melanoma cells were purchased from ATCC (American Type Culture Collection: Catalog No. CRL-6322), Dulbecco's Modified Eagle Medium (DMEM: Sigma) containing 10% fetal bovine serum and antibiotics. The one maintained and passaged in was used.

(2)被験物質:アルジオキサ、エテンザミド、塩酸フェニレフリン、グアイフェネシン、スルファメトキサゾール、パルミチン酸レチノール、ビサコジル、メチル硫酸ネオスチグミン及びレゾルシンはそれぞれ10%DMEMで溶解し、メンブランフィルターで除菌後、所定濃度に調製した。メラニン生成阻害の陽性対照物質としてはホルボール12−ミリステート13−アセテート(phorbol 12−myristate 13−acetate:PMA)あるいはコウジ酸(kojic acid:K.A.)を用いた。 (2) Test substances: aldioxa, etenzamide, phenylephrine hydrochloride, guaifenesin, sulfamethoxazole, retinol palmitate, bisacodyl, neostigmine methylsulfate, and resorcinol were each dissolved in 10% DMEM, sterilized with a membrane filter, and given concentration Prepared. As a positive control substance for inhibiting melanin production, phorbol 12-myristate 13-acetate (PMA) or kojic acid (KA) was used.

(3)試験方法:B16F0メラノーマ細胞は、10%DMEM培地で4×104/mLに調製し、その2mLを6穴プレートの各穴に添加し、5%二酸化炭素濃度、37℃で一晩培養した。翌日、所定濃度に調製した被験物質あるいはPMAをB16F0メラノーマ細胞にそれぞれ2mL添加し、さらに5%二酸化炭素濃度、37℃で72時間培養した。培養終了後、細胞内のメラニン含有量の測定はカゲヤマらの方法(The Journal of Biological Chemistry,279(26),27774−27780(2004))を一部改変して行った。B16F0細胞は、リン酸緩衝生理食塩液で洗浄後、1Nの水酸化ナトリウムを添加し、室温で20〜60分間放置した。続いてマイクロプレート・ミキサーで攪拌し、細胞を完全に溶解させ、細胞溶解液とした。細胞溶解液の120μLを200μLのマイクロチューブに移し、サーマル・サイクラーで80℃、1時間処理後、それぞれの80μLを96穴プレートの各穴に移し、マイクロ・プレートリーダーで405nmの吸収波長を指標にして細胞内メラニン量を測定した。なお、細胞内メラニン量は予め作成しておいた標準メラニンの標準曲線より算出した。また、上記細胞溶解液をリン酸緩衝生理食塩液で10倍希釈したB16F0細胞溶解液中の総タンパク質量はビーシーエープロテインアッセイキット(BCA Protein Assay Kit:PIERCE社製)を用いて測定した。B16F0細胞のメラニン含量は、上記で測定された処理液中のメラニン量と細胞溶解液中の総タンパクの質量から、処理液中のメラニン量(μg)/細胞溶解液中の総タンパク質量(mg)で表し、媒体対照群と比較したメラニン生成率を求めた。この結果を以下に示した。なお、試験結果はいずれも3例の平均値である。 (3) Test method: B16F0 melanoma cells were prepared to 4 × 10 4 / mL with 10% DMEM medium, and 2 mL thereof was added to each well of a 6-well plate, and 5% carbon dioxide concentration at 37 ° C. overnight. Cultured. On the next day, 2 mL each of the test substance or PMA prepared to a predetermined concentration was added to B16F0 melanoma cells, and further cultured at 5% carbon dioxide concentration and 37 ° C. for 72 hours. After completion of the culture, the intracellular melanin content was measured by partially modifying the method of Kageyama et al. (The Journal of Biological Chemistry, 279 (26), 27774-27780 (2004)). B16F0 cells were washed with phosphate buffered saline, 1N sodium hydroxide was added, and the mixture was allowed to stand at room temperature for 20 to 60 minutes. Subsequently, the mixture was stirred with a microplate mixer to completely lyse the cells to obtain a cell lysate. Transfer 120 μL of the cell lysate to a 200 μL microtube, treat with a thermal cycler at 80 ° C. for 1 hour, transfer 80 μL of each to each hole of a 96-well plate, and use a microplate reader with the absorption wavelength of 405 nm as an index. Then, the amount of intracellular melanin was measured. The amount of intracellular melanin was calculated from a standard curve of standard melanin prepared in advance. Further, the total protein amount in the B16F0 cell lysate obtained by diluting the cell lysate 10 times with phosphate buffered saline was measured using a BCA protein assay kit (manufactured by PIERCE). The melanin content of B16F0 cells is calculated from the amount of melanin in the treatment solution measured above and the total protein mass in the cell lysate, and the amount of melanin in the treatment solution (μg) / total protein in the cell lysis solution (mg ) And the melanin production rate compared with the vehicle control group was determined. The results are shown below. In addition, all the test results are average values of three cases.
