Description

技術分野
本発明はエゴノール誘導体からなるメラニン生成抑制剤及び美白剤、並びにエゴノール誘導体を含有する組成物、特に化粧料、医薬、皮膚外用剤、食品に関する。さらに詳細には、メラノサイトにおけるメラニン生成を抑制し、紫外線照射後の日焼け皮膚の美白、また、日焼け等によるしみ、そばかす、肝班等の皮膚の色素沈着を予防、改善及び治療することができるメラニン生成抑制剤及び美白剤、並びに組成物、特に化粧料、医薬、皮膚外用剤、食品に関する。
背景技術
日焼け等によるしみ、そばかす、肝班等の皮膚の色素沈着は加齢に伴って発生し、加齢に伴って増加、あるいは消失しにくくなるため、中高年齢層にとって悩みとなっている。これらの色素沈着の発症機構は未だ明確にされていないが、太陽光線(特に紫外線)による日焼け等によって、表皮細胞に存在するメラノサイト内のメラノソームとよばれるメラニン生成顆粒においてメラニン色素が産生され、生成したメラニン色素が隣接細胞へ拡散することによって生じると考えられている。
このような色素沈着を正常皮膚色にまで回復することが可能な物質の開発が強く望まれており、これまでに多くの物質が商品化されてきている。例えば、L−アスコルビン酸、コウジ酸、あるいはハイドロキノンなどが知られている。
しかし、L−アスコルビン酸は安定性に難があり、コウジ酸は一応効果が認められているものの、その効果は弱い。一方、ハイドロキノンも一応効果が認められているが、刺激性およびアレルギー性を有し、安全性に問題があり、薬剤として配合することには問題がある。したがって、充分な色素沈着予防および改善効果を有する物質は未だ知られていないのが現状である。
本発明に係る化合物は既知の物質であるが、メラニン生成を抑制する効果を有し、皮膚美白効果を持つことは知られていない(例えば、タカナシ等(Takanashi M.,Takizawa Y.)、フィトケミストリィ(Phytochemistry)(英国)、1988年、27巻、p.1224〜p.1226、アニル(Anil H.)、フィトケミストリィ(Phytochemistry)(英国)、1980年、19巻、p.2784〜p.2786参照。)。
本発明は上記事情に鑑みてなされたもので、その目的は、紫外線照射後の日焼け皮膚の美白、また日焼け等によるしみ、そばかす、肝斑等の皮膚の色素沈着の予防、改善及び治療に有効な物質及びこれを含有する組成物を提供することにある。

発明を実施するための最良の形態
以下、本発明の実施形態について詳述する。
本発明において用いられる下記の式(1)
Figure 2003047565
で示されるエゴノール誘導体(以下、単にエゴノール誘導体という。)は既知の物質であり、例えば、菌類から単離することができる。エゴノール誘導体の生成にはエゴノール誘導体を含むあらゆる菌類を用いることができるが、例えばマスタケ(Laetiporus sulphureus)を用いるのが好都合である。また、化学合成によって調製することも可能である。エゴノール誘導体を含む菌類からのエゴノール誘導体の単離は次のようにして行うことができる。すなわち、菌類の子実体または菌糸、胞子等の部分的個所を好ましくは粉砕した後、抽出溶媒中に浸漬するかまたは抽出溶媒中で加熱還流し、次いでろ過、遠心分離等により不溶物を除去して得られる抽出溶液を場合によって濃縮した後、公知の分離精製手段によって単離する。
抽出に用いる溶媒は、通常菌類、植物等の抽出に用いられる溶媒でよく、例えば、メタノール、エタノール等のアルコール、アセトン、酢酸エチル等の有機溶媒、水を単独であるいは組み合わせて用いることができる。抽出方法は通常の方法でよく、一般的には、抽出温度は、0〜100℃、好ましくは40〜70℃の範囲であり、抽出時間は、1〜168時間、好ましくは24〜72時間である。抽出溶液からの単離は、例えば、逆相クロマトグラフィー、ゲルろ過カラムクロマトグラフィー、液体クロマトグラフィー等のクロマトグラフィーによって行うことができる。
以下に、エゴノール誘導体の生成の具体例を挙げる。
[精製例(菌類からの単離)]
栽培したマスタケの子実体を粉砕した後、メタノールに浸漬し、40℃で72時間抽出を行った。次いで、ろ過により不溶物を除去し、得られた抽出溶液を濃縮した後、逆相クロマトグラフィーにより精製した。精製物の構造は、質量分析ガスクロマトグラフィーとNMRにより決定した。その化合物は、前記式(1)に示す、5−(3−hydroxypropyl)−7−methoxy−2−(3,4−methylenedioxyphenyl)benzofuranであり、エゴノールの誘導体であった。
本発明の前記エゴノール誘導体は、後述するようにメラニン生成抑制作用及び美白作用を有する。したがって、メラニン生成抑制剤及び美白剤として用いることができる。さらに、エゴノール誘導体を含有するメラニン生成抑制剤及び美白剤に応用することができる。これらのメラニン生成抑制剤及び美白剤は、メラノサイトにおけるメラニン生成を抑制し、紫外線照射後の日焼け皮膚の美白、また、日焼け等によるしみ、そばかす、肝班等の皮膚の色素沈着を予防、改善及び治療することができる。また、組成物として、エゴノール誘導体を含有する、メラニン生成抑制用組成物及び美白用組成物、さらに、エゴノール誘導体を含有する、化粧品,医薬品,食品分野における各種化粧料、医薬、皮膚外用剤、メラニン生成抑制用食品、美白用食品等に応用することができる。前記化粧料、医薬、皮膚外用剤は、前記エゴノール誘導体の機能を有したメラニン生成抑制用及び美白用としての応用が好ましい。前記組成物は、前記メラニン生成抑制及び美白に関連する症状等の予防、処置のための組成物である。
本発明の組成物は、経口用(内用)又は非経口用(外用)の両形態をとることができる。経口用の場合は、本発明の組成物を、例えば医薬または食品等の形態に調製することができる。また、非経口用の場合には、化粧料、医薬部外品、医薬、皮膚外用剤等の形態に調製することができる。

メラニン生成抑制作用は、マウス由来のメラニン生成細胞であるB16 10F7メラノーマ細胞(入手先:秋田県総合食品研究所より移譲)を用い、前記精製例で精製したエゴノール誘導体を培養液で稀釈した溶液を細胞に作用させメラニンの生成を観察し評価した。B−16細胞は70%コンフルエントの細胞をPBSにて洗いトリプシンを加え剥離し、トリプシンと同量の血清入り培地(E−MEM+10%FBS)を加え細胞を集め遠心した(800rpm,5min.)。細胞数をカウントし、約10cells/ml(E−MEM+10%FBS)に調整した。エゴノール誘導体溶液の稀釈は、細胞培養プレート(接着細胞用)に20μLの滅菌PBSを分注し、エゴノール誘導体溶液を20μL取り倍々稀釈した(培養液中の最終濃度100μg/mL〜0.0012μg/mL)。コントロールとしてアルブチン(培養液中の最終濃度140μg/mL〜0.22μg/mL)、メタノールも同様に稀釈した。
この稀釈液の入ったプレートに細胞浮遊液を80μLずつ分注した。さらに、37℃、COインキュベーターにて72時間培養し、顕微鏡により、細胞におけるメラニン生成を観察した。さらに、メラニンが生成されている場合、培地を除き300μLの1N、NaOHで、メラニンを溶かし、470nmの紫外線吸収を測定することでメラニン生成量を評価した。溶媒であるメタノールを反応させた値を100%とし、エゴノール誘導体、アルブチンを用量変化させ、もっとも低濃度でメラニン合成阻害を示す濃度を求めた。この結果を表1に示す。

Background art
Skin spots such as sunburn, freckles, and liver spots occur with aging and are difficult to increase or disappear with aging. The mechanism of the development of these pigmentations has not yet been clarified, but melanin pigments are produced and produced in melanin-producing granules called melanosomes in melanocytes existing in epidermal cells by sun rays (especially ultraviolet rays). It is thought to be caused by the diffusion of melanin pigments to adjacent cells.

[Example 1] Melanin production inhibitory effect
[Inhibition of melanin production in B16 melanoma cells]
Melanin production-suppressing action is achieved by using a B16 10F7 melanoma cell (obtained from Akita Prefectural Food Research Institute), a mouse-derived melanin-producing cell, and a solution obtained by diluting the egonol derivative purified in the purification example with a culture solution. It was allowed to act on cells to observe and evaluate the production of melanin. For B-16 cells, 70% confluent cells were washed with PBS, trypsin was added and detached, serum-containing medium (E-MEM + 10% FBS) in the same amount as trypsin was added, and the cells were collected and centrifuged (800 rpm, 5 min.). Count the number of cells, about 10 4 adjusted to cells / ml (E-MEM + 10% FBS). To dilute the egonol derivative solution, 20 μL of sterile PBS was dispensed into a cell culture plate (for adherent cells), and 20 μL of the egonol derivative solution was diluted in multiple dilutions (final concentration in the culture solution: 100 μg / mL to 0.0012 μg / mL). ). As controls, arbutin (final concentration in the culture solution: 140 μg / mL to 0.22 μg / mL) and methanol were also diluted in the same manner.
80 μL of the cell suspension was dispensed into the plate containing the diluted solution. Furthermore, 37 ° C, CO 2 The cells were cultured in an incubator for 72 hours, and melanin production in the cells was observed with a microscope. Furthermore, when melanin was produced | generated, the melanin production amount was evaluated by melt | dissolving melanin with 300 microliters 1N and NaOH except the culture medium and measuring a 470 nm ultraviolet-ray absorption. The value obtained by reacting methanol as a solvent was taken as 100%, and the doses of the egonol derivative and arbutin were changed, and the concentration at which melanin synthesis was inhibited at the lowest concentration was determined. The results are shown in Table 1.
Figure 2003047565
As can be seen from Table 1, the egonol derivative exhibits a melanin production inhibitory action (whitening action) similar to that of arbutin, which is a melanin production inhibitor, on melanoma B16 cells, and is useful as a melanin production inhibitor and a whitening agent. It is clear that there is.
In addition, in the case of an egonol derivative, the blackness of B-16 cells was suppressed to the same extent as in the case of arbutin, and it was confirmed that the derivative had excellent melanin production inhibitory effect and whitening effect.

(result)
The determination results are shown in Table 4. Table 4 shows the number of persons corresponding to each determination item by determination.

As is clear from Table 4, the whitening effect of the egonol derivative, that is, the melanin production inhibitory effect is synergistically improved by combining the egonol derivative with ascorbic acid 2-glucoside or ascorbic acid phosphate magnesium salt. I understand that.
Examples of the present invention in which compositions having various formulations are prepared by conventional methods are shown below. In any of the examples, excellent melanin production suppressing effect and whitening effect were observed.
