【発明が属する技術分野】
本発明は、皮膚基底膜に存在する細胞外マトリックスタンパク質の一種であるラミニン5の産生を促進する活性を有するある特定の化合物を有効成分として含有する皮膚基底膜賦活用組成物に関する。
【0002】
【従来の技術】
ラミニン5(別名カリニン、エピリグリン、ナイセイン)は皮膚の基底膜に存在するラミニン分子種の一種として同定され、α3鎖、β3鎖、γ2鎖の3本のサブユニットで構成される分子量380〜490kDaの糖タンパク質である(Carter,W.G.,et al.,Cell.,65,599−610,1991.,Rousselle,P.,et al.,J.Cell Biol.,114,567−576,1991.,Verrando,P.,et al.,Biochem.Biophys.Acta,942,45−56,1988.)。ラミニン5は表皮細胞により産生され、表皮細胞の接着を促進し、表皮細胞を基底膜に結合するとともに、VII型コラーゲンと結合し、真皮と基底膜の結合にも関与している(Rousselle,P.,et al.,J.Cell Biol.,114,567−576,1991.,Rousselle,P.,et al.,J.Cell Biol.,138,719−728,1997.,Chen,M.,et al.,J.Invest.Dermatol.,112,177−183,1999)。ラミニン5遺伝子の変異は、表皮・真皮間の剥離と水泡形成を特徴とする重篤な遺伝的疾患である結合型表皮水泡症(Herlitz’s junctional epidermolysis bullosa)を引き起こすことから、ラミニン5は正常な皮膚構造の維持に必要不可欠であることが明らかになった(Aberdam,D.,et al.,Nat.Genet.,6,299−304,1994.,Pulkkinen,L.,et al.,Genomics,24,357−360,1994.,Kivirikko,S.,et al.,Hum.Mol.Genet.,4,959−962,1995.)。また、ラミニン5は表皮細胞の遊走を促進させる活性を持ち、かつ皮膚の創傷治癒部位でラミニン5遺伝子およびその受容体遺伝子の発現が上昇することから、創傷治癒に関与することが示唆されている(Verrndo,P.,et al.,Lab.Invest.,71,567−574,1994.,Ryan,M.C.,J.Biol.Chem.,269,22779−22787,1994.)。以上のようなことから、ラミニン5は、表皮と真皮の結合を担い、正常な皮膚構造の維持に重要であるとともに、皮膚が損傷を受けた場合には、表皮細胞の遊走を促進し、創傷治癒に働くと考えられる。
【0003】
一方、老化した皮膚では基底膜の重複や偏平化が起こっていることから、基底膜の構造変化が皮膚老化を引き起こす可能性が示唆されている(Lavker,R.,et al.,J.Invest.Dermatol.,73,59−389,1979.,Lavker,R.,et al.,Dermatol.Clin.,4,379−389,1986.)。また、老化したヒトの真皮の線維芽細胞では、皮膚基底膜の主要な構成成分であるIV型コラーゲンの発現が低下していることから、老化に伴い皮膚基底膜の活性が低下することが示唆されている(Olsen,D.,et al.,J.Invest.Dermatol.,93,127−131,1989.)。したがって、表皮細胞におけるラミニン5の産生を促進し、老化による皮膚基底膜の構造変化を防止または修復することにより、皮膚の機能低下を改善できることが予想されていた。
【0004】
上記のようなことから、ラミニン5自体あるいはラミニン5の産生促進活性を持つ大豆由来の調製物やリゾリン脂質を有効成分として含有することにより、皮膚賦活効果などを有する皮膚外用剤や皮膚賦活用組成物が開発されている(特開平10-147515、特開平11-343226、特開平11-52704、特開2000-226308)。
【0005】
ところで、これまでフェニルプロパノイド類の化合物は、様々な理由から化粧料や皮膚外用剤などに用いられている。例えば、フェニルプロパノイド類の化合物が紫外線吸収活性、チロシナーゼ阻害活性、メラニン産生抑制活性をもつことから、イソフェルラ酸および/またはその誘導体(特許第1928802号公報)、フェルラ酸アミド誘導体(特許第1945459号公報)、イソフェルラ酸および/またはその塩とアスコルビン酸および/またはその誘導体および多価アルコール(特許第2533773号公報)、イソフェルラ酸および/またはその塩と抗酸化剤(特許第2533774号公報)、イソフェルラ酸および/またはその塩と多価アルコール(特許第2533775号公報)、イソフェルラ酸および/またはその塩と有機酸および/またはその塩(特許第2533776号公報)、フェルラ酸および/またはその塩と有機酸および/またはその塩(特許第2564139号公報)、カフェー酸配糖体(特許第2997358号公報)、フェルラ酸−2,3−ジヒドロキシプロピルおよび/またはその塩(特開平6−157272)を有効成分として含有する化粧料および皮膚外用剤が開発されている。フェルラ酸および/またはフェルラ酸エステルがヒト正常線維芽細胞の分化を促進することを見出し、それらを有効成分として含有する細胞分化促進剤、育毛・発毛剤、皮膚老化防止剤が開発されている(特開平5−310526)。カフェー酸、フェルラ酸、コニフェリルアルコールが活性酸素消去作用を有することを見出し、それらの活性酸素消去剤を有効成分として含有する化粧料、医薬組成物および食用組成物が開発されている(特開平7−300412)。フェルラ酸エステルを有効成分とする抗酸化剤が開発されている(特開平9−40613)。フェニルプロパノイド類の化合物に太陽光紫外線および大気汚染物質による光毒性を抑制する効果を見出し、それらの光毒性抑制剤を有効成分として含有する化粧料および飲食品が開発されている(特開2000−319154)。
【0006】
【発明が解決しようとする課題】
しかしながら、ラミニン5を有効成分として含有する皮膚外用剤は、ラミニン5が非常に高分子の糖タンパク質であることから、安定性、皮膚浸透性などに問題があり、必ずしも十分な皮膚賦活用効果を期待できない。また、大豆由来の調製物やリゾリン脂質は、ラミニン5の産生を促進させる活性が十分でなく、それらを有効成分として含有する皮膚賦活用組成物は、必ずしも十分な皮膚賦活効果を期待できない。
【0007】
一方、フェニルプロパノイド類の化合物には前述したような活性が知られているが、皮膚基底膜成分に着目しその成分の産生を促進することで、皮膚基底膜ひいては皮膚全体を賦活化しようという試みはなされていない。
【0008】
【課題を解決するための手段】
本発明者らは、種々の化合物について、表皮細胞におけるラミニン5の産生を促進する活性を検討した。その結果、ケイヒ酸、ケイヒアルデヒド、オイゲノール、コニフェリルアルコール、カフェー酸、クロロゲン酸がラミニン5産生を有意に促進させることを見出し、本発明を完成した。
【0009】
すなわち、本発明は、
ケイヒ酸、ケイヒアルデヒド、オイゲノール、コニフェリルアルコール、カフェー酸、クロロゲン酸より選ばれる1種または2種以上の化合物および/またはその塩および/またはその配糖体を含有するラミニン5の産生促進用組成物、

【0011】
自然界では、維管束植物においてアミノ酸フェニルアラニン(イネ科ではチロシン)の脱アミノ化によりトランスケイヒ酸(イネ科ではp−クマリン酸)が生成される。トランスケイヒ酸は酸化されてp−クマリン酸、さらに酸化されてカフェー酸となる。カフェー酸はメチル化を受けてフェルラ酸となる。被子植物はフェルラ酸をさらに酸化して5−ヒドロキシフェルラ酸に、次にメチル化してシナピック酸とすることができるが、シダ植物や裸子植物はできない。自然界において、これら酸のフェノール性水酸基は部分的にメチル化され、そしてカルボキシル基は逐次還元されて対応するアルデヒド、アルコール、あるいはオレフィンとなる(天然物化学、改訂第4版、三橋博ら編、南江堂)。

【0023】
【化6】

試験結果1.表皮角化細胞におけるラミニン5産生能の測定試験;
表皮角化細胞および培地(KGM)は、胎児由来正常ヒト表皮角化細胞およびKeratinocyte Growth Medium Bullet Kit(旭テクノグラス)を用いた。細胞はKGMで37℃−5%COインキュベーターにて培養した。本実験には継代数が3〜5代の細胞を使用した。
【0033】
KGMで継代培養した表皮角化細胞をトリプシン/EDTA溶液を用いて培養ディッシュから剥がした後、トリプシン中和溶液を用いてトリプシンを中和した。遠心分離により細胞を集めた後、KGMにて再懸濁し、2×10cells/ウェルとなるように96ウェルプレートに播種し、24時間培養した。ケイヒ酸、ケイヒアルデヒド、オイゲノール、コニフェリルアルコール、カフェー酸、フェルラ酸、クロロゲン酸を100μg/mlで処理し、さらに24時間培養し、細胞培養上清を回収した。800rpm、5分間遠心して浮遊細胞を除去後、15000rpm、30分間遠心して細胞片を除去し、ELISA用サンプルとして用いた。
【0034】
細胞培養上清液をリン酸緩衝溶液{PBS(−)}で適当に希釈し、96ウェルELISA用プレートに37℃で2時間吸着させた。細胞培養上清液を除去後、ブロッキング溶液{1%の牛血清アルブミン(BSA)を含むPBS(−)}に浸し、37℃で1時間ブロッキングした。洗浄液{0.05%のポリオキシエチレン(20)ソルビタンモノラウレート(和光純薬)を含むPBS(−)}にて洗浄後、一次抗体溶液{洗浄液で5mg/mlに調製したラミニンγ2鎖に対するモノクローナル抗体(クローンD4B5)(Mizushima,H.,et al.,Horm.Res.,50,7−14,1998.)}を添加し、37℃で2時間反応させた。洗浄後、二次抗体{洗浄液で1mg/mlに調製したビオチン化抗マウスイムノグロブリンG(Vector laboratories)}を添加し、室温で1時間反応させた。洗浄後、酵素溶液{洗浄液で1mg/mlに調製したアルカリフォスファターゼアビジンD(Vector laboratories)}を添加し、室温で1時間反応させた。洗浄後、基質液{1mg/mlのp−nitrophenyl phosphate(ICN Biomedicals,Inc.)を含む0.75M Tris−HCl(pH10.3)}を添加し、37℃で30分反応後、405nmでの吸光度を測定した。
結果を表1に示す。
【0035】
【表1】
各化合物を処理した時のラミニン5の産生について、無処理対照を100%として評価した結果、いずれの化合物もラミニン5産生を有意に促進した。尚、ラミニン5の産生を促進することが知られている上皮細胞成長因子(EGF)(Sigma−Aldrich Co.)(Mizushima,H.,et al.,J.Biochem.,120,1196−1202,1996.)を50ng/mlで処理した場合も同様にラミニン5の産生を有意に促進した。
【0036】
参考試験結果1.光傷害抑制効果の測定試験;
(1)ヒト表皮角化細胞の光傷害抑制効果の測定試験;ヒト表皮角化細胞をKGMで培養後、トリプシン/EDTA溶液を用いて、接着細胞を培養ディッシュから剥がした後、トリプシン中和溶液を用いてトリプシンを中和した。遠心分離により細胞を集めた後、2×10cells/mlとなるようにKGMにて再懸濁した。この細胞懸濁液に100μg/mlのフェルラ酸および5μg/mlのラミニン5中和抗体(Chemicon,cloneP3H9−2)をそれぞれ単独または組み合せて処理した。本実験では、フェルラ酸の光傷害抑制効果が、ラミニン5の産生促進に依るものかどうかについて調べるために、ラミニン5中和抗体を用いた。この細胞懸濁液を24ウェルプレートに1ml/ウェルで播種し、24時間培養した。UVBを0、75および125mJ/cmで照射し、さらに24時間培養した。PBS(−)で洗浄し浮遊細胞を除去した後、5%グルタルアルデヒド水溶液にて室温、15分間処理し、細胞を固定した。水道水にて洗浄後、蛍光染色液{5μg/mlのHoechst33342(Sigma−Aldrich Co.)および0.001%のポリオキシエチレン(10)オクチルフェニルエーテル(和光純薬)を含む水溶液}を室温、暗所にて1.5時間処理した。水道水にて洗浄後、蛍光プレートリーダーを用いて、蛍光強度を測定することにより細胞生存率を評価した。
【0037】
結果を図1に示す。フェルラ酸およびラミニン5中和抗体を無処理で、UVB非照射の場合を100%として光障害抑制効果を評価した。UVB非照射の場合は、フェルラ酸およびラミニン5中和抗体をそれぞれ単独または組み合せて処理したいずれの場合でも、無処理と同程度の細胞生存率であった。一方、UVBを75および125mJ/cmで照射した場合は、無処理に比べて、フェルラ酸を処理した場合は有意に細胞生存率が上昇した。フェルラ酸およびラミニン5中和抗体を組み合せて処理した場合の細胞生存率は、無処理と同程度であった。よって、フェルラ酸の光傷害抑制効果はラミニン5の産生促進に起因すると考えられる。
【0038】
(2)ヒト皮膚三次元モデルの光傷害抑制効果の測定試験;
ヒト皮膚三次元モデルは、TESTSKIN(LSE−high)(東洋紡績)を用い、プロトコールにしたがって培養した。フェルラ酸(100μg/ml)を含む培地をアッセイリング内の組織上に添加し、24時間培養した。UVBを0、120、240および360mJ/cmで照射し、さらに24時間培養した。組織培養液を回収し、15000rpm、30分間遠心して組織片を除去した。
【0039】
この組織培養液を用いて、細胞膜に傷害を受けた細胞から遊離される乳酸脱水素酵素(LDH)活性を測定することにより、細胞毒性を測定した。LDH活性の測定は、LDH−細胞毒性テストキット(和光純薬)を用いて行った。PBS(−)を用いて適当に希釈した組織培養液を96ウェルの反応プレートに分注後、発色液を処理し、室温で20分間反応させた。反応停止液を処理後、マイクロプレートリーダーにより560nmの吸光度を測定し、細胞毒性を評価した。
【0040】
結果を図2に示す。フェルラ酸を無処理で、UVBを非照射の場合の細胞毒性率を100%として評価した。UVBを非照射の場合は、フェルラ酸の処理の有無に関わらず、ほぼ同程度の細胞毒性率であった。一方、UVBを照射した場合は、UVBの照射量が増えるにつれて、細胞毒性率は高くなるが、フェルラ酸を処理した場合は、無処理に比べて細胞毒性が有意に低下した。

[Technical field to which the invention belongs]
The present invention relates to a skin basement membrane utilization composition containing, as an active ingredient, a specific compound having an activity of promoting the production of laminin 5, which is a kind of extracellular matrix protein present in the skin basement membrane.
[0002]
[Prior art]
Laminin 5 (also known as kalinin, epiligrin, and nisin) is identified as a kind of laminin molecular species present in the skin basement membrane, and has a molecular weight of 380 to 490 kDa composed of three subunits of α3 chain, β3 chain, and γ2 chain. It is a glycoprotein (Carter, WG, et al., Cell., 65, 599-610, 1991., Rousselle, P., et al., J. Cell Biol., 114, 567-576, 1991). , Verrando, P., et al., Biochem. Biophys. Acta, 942, 45-56, 1988.). Laminin 5 is produced by epidermal cells, promotes adhesion of epidermal cells, binds the epidermal cells to the basement membrane, binds to type VII collagen, and is also involved in the binding of the dermis to the basement membrane (Rousselle, P , Et al., J. Cell Biol., 114, 567-576, 1991., Rousselle, P., et al., J. Cell Biol., 138, 719-728, 1997., Chen, M.,. et al., J. Invest. Dermatol., 112, 177-183, 1999). Mutations in the laminin 5 gene cause hereditary epidermolysis bullosa (Herlitz's junctional epidermolysis bullosa), which is a severe genetic disease characterized by epidermis-dermis separation and blister formation. (Aberdam, D., et al., Nat. Genet., 6, 299-304, 1994., Pulkkinen, L., et al., Genomics). , 24, 357-360, 1994., Kiviriko, S., et al., Hum. Mol. Genet., 4, 959-962, 1995.). In addition, laminin 5 has an activity of promoting epidermal cell migration, and expression of laminin 5 gene and its receptor gene is increased at the wound healing site of skin, suggesting that it is involved in wound healing. (Verrndo, P., et al., Lab. Invest., 71, 567-574, 1994., Ryan, MC, J. Biol. Chem., 269, 22779-22787, 1994.). As described above, laminin 5 is responsible for the connection between the epidermis and the dermis and is important for maintaining a normal skin structure. When the skin is damaged, laminin 5 promotes the migration of epidermal cells, It seems to work for healing.
[0003]
On the other hand, in the aged skin, duplication and flattening of the basement membrane have occurred, suggesting that structural changes in the basement membrane may cause skin aging (Lavker, R., et al., J. Invest. Dermatol., 73, 59-389, 1979., Lavker, R., et al., Dermatol. Clin., 4, 379-389, 1986.). In addition, in the aging human dermal fibroblasts, the expression of type IV collagen, which is a major component of the skin basement membrane, is decreased, suggesting that the activity of the skin basement membrane decreases with ageing. (Olsen, D., et al., J. Invest. Dermatol., 93, 127-131, 1989.). Therefore, it has been expected that reduction of skin function can be improved by promoting the production of laminin 5 in epidermal cells and preventing or repairing structural changes in the skin basement membrane due to aging.
[0004]
From the above, laminin 5 itself, preparations derived from soybeans having laminin 5 production-promoting activity and lysophospholipids as active ingredients, skin external preparations and skin utilization compositions having skin activation effects Products have been developed (JP-A-10-147515, JP-A-11-343226, JP-A-11-52704, JP-A-2000-226308).

By the way, the compounds of phenylpropanoids have been used in cosmetics and skin external preparations for various reasons. For example, since phenylpropanoid compounds have ultraviolet absorption activity, tyrosinase inhibitory activity, and melanin production inhibitory activity, isoferulic acid and / or a derivative thereof (Patent No. 1928802), ferulic acid amide derivative (Patent No. 1945459) Gazette), isoferulic acid and / or its salt and ascorbic acid and / or its derivative and polyhydric alcohol (Japanese Patent No. 2533377), isoferulic acid and / or its salt and antioxidant (Japanese Patent No. 2533774), isoferula Acids and / or salts thereof and polyhydric alcohols (Patent No. 2533375), isoferulic acid and / or salts thereof and organic acids and / or salts thereof (Patent No. 2533776), ferulic acids and / or salts thereof and organics Acid and / or Its salt (Japanese Patent No. 2564139), caffeic acid glycoside (Japanese Patent No. 2997358), ferulic acid-2,3-dihydroxypropyl and / or its salt (Japanese Patent Laid-Open No. 6-157272) are contained as active ingredients.

[0006]
[Problems to be solved by the invention]
However, an external preparation for skin containing laminin 5 as an active ingredient has problems in stability, skin permeability, etc. because laminin 5 is a very high molecular weight glycoprotein, and does not necessarily have a sufficient skin utilization effect. I can't expect it. In addition, preparations derived from soybeans and lysophospholipids do not have sufficient activity to promote the production of laminin 5, and skin utilization compositions containing them as active ingredients cannot necessarily be expected to have a sufficient skin activation effect.
[0007]
On the other hand, phenylpropanoid compounds are known to have the above-mentioned activities, but by focusing on the skin basement membrane component and promoting the production of that component, it is intended to activate the skin basement membrane and thus the entire skin. No attempt has been made.
[0008]
[Means for Solving the Problems]
The inventors examined the activity of various compounds to promote the production of laminin 5 in epidermal cells. As a result, it was found that cinnamic acid, cinnaldehyde, eugenol, coniferyl alcohol, caffeic acid and chlorogenic acid significantly promote laminin 5 production, and the present invention was completed.
[0009]
That is, the present invention
Composition for promoting production of laminin 5 containing one or more compounds selected from cinnamic acid, cinnaldehyde, eugenol, coniferyl alcohol, caffeic acid and chlorogenic acid and / or a salt thereof and / or a glycoside thereof object,
About.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Cinnamic acid, cinnamic aldehyde, eugenol, coniferyl alcohol, caffeic acid, and chlorogenic acid are one of a group of compounds that exist in nature, and linear 3-carbon (C3, propane) is present in the benzene nucleus (C6, phenyl). It is a combination. These compounds can be obtained directly or indirectly from a wide range of biological sources, but may be chemically synthesized.
[0011]
In nature, transcinnamic acid (p-coumaric acid in Gramineae) is produced by deamination of the amino acid phenylalanine (tyrosine in Gramineae) in vascular plants. Transcinnamic acid is oxidized to p-coumaric acid and further oxidized to caffeic acid. Caffeic acid is methylated to ferulic acid. Angiosperms can further oxidize ferulic acid to 5-hydroxyferulic acid and then methylate to synaptic acid, but not fern or gymnosperms. In nature, the phenolic hydroxyl groups of these acids are partially methylated, and the carboxyl groups are sequentially reduced to the corresponding aldehyde, alcohol, or olefin (Natural Product Chemistry, 4th revised edition, edited by Hiroshi Mitsuhashi, Nanedo).
[0012]
Caffeic acid is represented by the following formula (1) and has an inhibitory effect on histamine release from mast cells and an inhibitory activity on 5-lipoxygenase and leukotriene production (Natural Drug Dictionary, Takuma Okuda, 1986, Yodogawa Shoten). It exists as a constituent of chlorogenic acid, mugwort and 3,5-di-O-caffeylquinic acid, which is a main component of homologous plants, and other so-called caffeine tannins contained in coffee beans, yarrow and hypericum. It is also free and present in a wide range of plants such as tobacco leaves, sweet potatoes and pear leaves. It is obtained by heating a mixture of 3,4-dihydroxybenzaldehyde, acetic anhydride and potassium acetate (Parkin reaction). It is also produced by acid hydrolysis of chlorogenic acid.
[0013]
[Chemical 1]
[0016]
Cinnamic acid is represented by the following formula (3), and esters thereof are used as perfumes and pharmaceuticals (Natural Drug Dictionary, Takuma Okuda, 1986, Yodogawa Shoten). Usually, cinnamic acid refers to the trans form, and the cis form is called arrocinic acid. The cis form is unstable and tends to be a transformer form. It exists as a free acid or ester in resins such as cassia oil, perubalsum, and trubalsum. It can be obtained by oxidizing cinnamaldehyde or heating a mixture of benzaldehyde, acetic anhydride and potassium acetate (Perkin reaction).
[0017]
[Chemical 3]
[0018]
Keihialdehyde is represented by the following formula (4) and has a strong peculiar aroma and sweetness, so it is used in food flavors such as confectionery (Natural Drug Dictionary, Takuma Okuda, 1986, Yodogawa Shoten). It is also used for pharmaceuticals and cosmetics. It is contained in the bark and leaves of Kay, and it is the main component of scented oil and cassia oil, and it is also contained in myrrh oil and patchouli oil. Obtained by condensing benzaldehyde and acetaldehyde with alkali.
[0019]
[Formula 4]
[0020]
Eugenol is represented by the following formula (5) and is used as a raw material for producing vanillin, a fragrance, a bactericidal agent, an antiseptic and the like (Natural Drug Dictionary, Takuma Okuda, Yodogawa Shoten). In addition to being abundant in clove oil, it is a phenolic essential oil component widely present in essential oils of plants. It can be obtained by alkaline extraction of glove oil and cinnamon oil.
[0021]
[Chemical formula 5]
[0022]
Coniferyl alcohol is represented by the following formula (6) and is present as a glycoside coniferin in the conifer formation layer and its surrounding parenchyma, comfrey root, sugar beet, asparagus, etc. (Natural drug dictionary, Takuo Okuda) Hen, 1986, Yodogawa Shoten). It becomes a lignin-like substance by dehydrogenative polymerization in the plant body. Lignin has been recognized to have antitumor effects, liver catalase activity promoting effects and the like. It is obtained by allowing the enzyme hydrolase emulsin to act on coniferin.
[0023]
[Chemical 6]
[0024]
Chlorogenic acid is represented by the following formula (7) and has the effect of promoting gastric juice and bile secretion in addition to the central nervous excitability (natural drug dictionary, Takuma Okuda, 1986, Yodogawa Shoten). Antioxidant action (Japan Women's University, Professor Nguyen et al., 1995) and cancer cell metastasis inhibitory action (Tokyo University of Agriculture and Technology, Prof. Yagasaki et al., 2000) have been reported. Although isolated from coffee beans for the first time, it is widely distributed in the fruits and leaves of dicotyledonous plants, and many of them are particularly found in plants such as eggplants, asteraceae, and ceraceae. It is obtained by esterifying caffeic acid and quinic acid.
[0025]
[Chemical 7]
Any compound is commercially available and can be used.
[0026]
According to the present invention, cinnamic acid, cinnamic aldehyde, eugenol, coniferyl alcohol, caffeic acid, chlorogenic acid promotes the production of laminin 5 in epidermal keratinocytes.

【Example】
EXAMPLES Next, although an Example is given and this invention is further demonstrated, this invention is not limited to these Examples.
[0031]
Preparation Preparation of Compound-Containing Liquid: Cinnamic acid, cinnaldehyde, eugenol, coniferyl alcohol, caffeic acid, ferulic acid, and chlorogenic acid (all Sigma-Aldrich Co.) were prepared at 10 mg / ml with 99.5% ethanol.
[0032]
Test results 1. Measurement test of laminin 5 producing ability in epidermal keratinocytes;
As the epidermal keratinocytes and medium (KGM), fetal-derived normal human epidermal keratinocytes and Keratinocyte Growth Medium Bullet Kit (Asahi Techno Glass) were used. The cells were cultured with KGM in a 37 ° C.-5% CO 2 incubator. In this experiment, cells having passage numbers 3 to 5 were used.
[0033]
Epidermal keratinocytes subcultured with KGM were peeled off from the culture dish using a trypsin / EDTA solution, and then trypsin was neutralized using a trypsin neutralization solution. Cells were collected by centrifugation, resuspended in KGM, seeded in a 96-well plate at 2 × 10 4 cells / well, and cultured for 24 hours. Cinnamic acid, cinnamic aldehyde, eugenol, coniferyl alcohol, caffeic acid, ferulic acid, and chlorogenic acid were treated with 100 μg / ml and further cultured for 24 hours, and the cell culture supernatant was collected. After removing floating cells by centrifuging at 800 rpm for 5 minutes, the cell debris was removed by centrifuging at 15000 rpm for 30 minutes and used as a sample for ELISA.
[0034]
The cell culture supernatant was appropriately diluted with a phosphate buffer solution {PBS (−)} and adsorbed on a 96-well ELISA plate at 37 ° C. for 2 hours. After removing the cell culture supernatant, the cells were immersed in a blocking solution {PBS (−) containing 1% bovine serum albumin (BSA)} and blocked at 37 ° C. for 1 hour. After washing with a washing solution {PBS (-)} containing 0.05% polyoxyethylene (20) sorbitan monolaurate (Wako Pure Chemical Industries, Ltd.)}, the primary antibody solution {for laminin γ2 chain prepared to 5 mg / ml with the washing solution Monoclonal antibody (clone D4B5) (Mizushima, H., et al., Horm. Res., 50, 7-14, 1998.)} was added and reacted at 37 ° C. for 2 hours. After washing, a secondary antibody {biotinylated anti-mouse immunoglobulin G (Vector laboratories) prepared to 1 mg / ml with a washing solution} was added and reacted at room temperature for 1 hour. After washing, an enzyme solution {alkaline phosphatase avidin D (Vector laboratories) prepared to 1 mg / ml with a washing solution} was added and reacted at room temperature for 1 hour. After washing, a substrate solution {0.75 M Tris-HCl (pH 10.3) containing 1 mg / ml p-nitrophenyl phosphate (ICN Biomedicals, Inc.)} was added, reacted at 37 ° C. for 30 minutes, and then at 405 nm. Absorbance was measured.
The results are shown in Table 1.
[0035]
[Table 1]
The production of laminin 5 when each compound was treated was evaluated with the untreated control as 100%. As a result, all compounds significantly promoted laminin 5 production. In addition, epidermal growth factor (EGF) (Sigma-Aldrich Co.) (Mizushima, H., et al., J. Biochem., 120, 1196-1202, known to promote the production of laminin 5 1996.) was also significantly promoted in the production of laminin 5 when treated with 50 ng / ml.
[0036]
Reference test results Measurement test of light injury suppression effect;
(1) Measurement test of the effect of suppressing photodamage of human epidermal keratinocytes; after culturing human epidermal keratinocytes with KGM, using a trypsin / EDTA solution, the adherent cells are peeled off from the culture dish, and then a trypsin neutralizing solution. Was used to neutralize trypsin. After collecting the cells by centrifugation, the cells were resuspended in KGM to 2 × 10 5 cells / ml. This cell suspension was treated with 100 μg / ml ferulic acid and 5 μg / ml laminin 5 neutralizing antibody (Chemicon, cloneP3H9-2), either alone or in combination. In this experiment, a laminin 5 neutralizing antibody was used in order to examine whether the effect of ferulic acid on photodamage suppression depends on the promotion of laminin 5 production. This cell suspension was seeded at 1 ml / well in a 24-well plate and cultured for 24 hours. UVB was irradiated at 0, 75 and 125 mJ / cm 2 and further cultured for 24 hours. After washing with PBS (−) to remove floating cells, the cells were fixed with 5% glutaraldehyde aqueous solution at room temperature for 15 minutes. After washing with tap water, fluorescent staining solution {5 μg / ml Hoechst 33342 (Sigma-Aldrich Co.) and 0.001% polyoxyethylene (10) octylphenyl ether (Wako Pure Chemical Industries, Ltd., aqueous solution)} at room temperature, Treated in the dark for 1.5 hours. After washing with tap water, the cell viability was evaluated by measuring the fluorescence intensity using a fluorescence plate reader.
[0037]
The results are shown in FIG. The effect of inhibiting light damage was evaluated with no treatment of ferulic acid and laminin 5 neutralizing antibody, and 100% UVB non-irradiation. In the case of non-UVB irradiation, the cell viability was comparable to that in the case of no treatment in either case where ferulic acid and laminin 5 neutralizing antibody were treated alone or in combination. On the other hand, when UVB was irradiated at 75 and 125 mJ / cm 2 , the cell viability was significantly increased when ferulic acid was treated as compared to no treatment. The cell viability when treated with a combination of ferulic acid and laminin 5 neutralizing antibody was similar to that of no treatment. Therefore, it is thought that the photodamage suppression effect of ferulic acid is caused by the promotion of laminin 5 production.
[0038]
(2) Measurement test of the photoinjury inhibitory effect of a three-dimensional human skin model;
The human skin three-dimensional model was cultured using TESTSKIN (LSE-high) (Toyobo) according to the protocol. Medium containing ferulic acid (100 μg / ml) was added onto the tissue in the assay ring and cultured for 24 hours. UVB was irradiated at 0, 120, 240 and 360 mJ / cm 2 and further cultured for 24 hours. The tissue culture solution was collected and centrifuged at 15000 rpm for 30 minutes to remove tissue pieces.
[0039]
Cytotoxicity was measured by measuring lactate dehydrogenase (LDH) activity released from cells damaged by the cell membrane using this tissue culture solution. The LDH activity was measured using an LDH-cytotoxicity test kit (Wako Pure Chemical Industries). A tissue culture solution appropriately diluted with PBS (-) was dispensed into a 96-well reaction plate, and then the color developing solution was treated and reacted at room temperature for 20 minutes. After processing the reaction stop solution, the absorbance at 560 nm was measured with a microplate reader to evaluate cytotoxicity.
[0040]
The results are shown in FIG. The cytotoxicity rate in the case of no treatment with ferulic acid and no irradiation with UVB was evaluated as 100%. When UVB was not irradiated, the cytotoxicity rate was almost the same regardless of the presence or absence of ferulic acid treatment. On the other hand, when UVB was irradiated, the cytotoxic rate increased as the dose of UVB increased, but when ferulic acid was treated, the cytotoxicity was significantly reduced compared to no treatment.
