【発明の属する技術分野】
本発明は抗プラスミン剤に関する。さらに詳しくは、プラスミン(Plasmin)やプラスミノーゲンアクチベーター(Plasminogen activator;PA)の活性に対して優れた拮抗作用を有する抗プラスミン剤に関する。本発明は、プラスミン、PAの活性変化が認められる種々の疾患を改善する製剤に適用され、特に、患部において前記プラスミン、PA活性変化が認められる接触性皮膚炎、乾癬、尋常性天疱瘡、先天性水疱瘡等の種々の皮膚疾患の他、乾燥や洗浄剤等によって惹起される肌荒れ、荒れ性に対して優れた改善、予防効果を有する皮膚外用剤に有利に適用される。
【0002】
【従来の技術および発明が解決しようとする課題】
従来より、皮膚疾患や肌荒れに対して改善・予防効果を有するものとして種々の治療薬、皮膚外用剤、化粧料等が知られている。これら従来の薬剤や化粧料等においては、有効成分として、消炎剤やアミノ酸、多糖、脂質等の他、抗炎症作用、あるいは高い保湿作用を有する各種動植物抽出エキスが、皮膚の炎症や角質層の水分の消失を防ぐ能力に優れているために用いられてきた。しかしながらいずれにおいてもその肌荒れ改善・予防効果は必ずしも十分ではなく、より優れた薬効剤の開発が期待されていた。
【0003】
一方、皮膚の正常な角化過程においては、表皮細胞内のタンパク質分解酵素(プロテアーゼ)が重要な役割を果たしていると考えられているが(Ogawa H., Yoshiike T., "Int. J. Dermatol.";23,1984)、近年、種々の皮膚疾患の病像形成には特にプラスミン(Plasmin)やプラスミノーゲンアクチベーター(Plasminogen activator;PA)といった線溶系に関わるプロテアーゼの活性変化が深く関与していることが明らかにされつつある。PAはプラスミンの前駆体であるプラスミノーゲンに特異的に働いて、それを活性なプラスミンに変換するプロテアーゼである。このPAと皮膚疾患との関係については、例えば、炎症性異常角化性疾患の代表である乾癬では、その患部表皮の錯角化部位に強いPA活性が存在すること(Haustein, "Arch. Klin. Exp. Dermatol.";234,1969)や、乾癬鱗屑から高濃度の塩溶液を用いてPAを抽出したという報告(Fraki,Hopsu-Havu, "Arch. Dermatol. Res";256,1976)がなされている。また、尋常性天疱瘡においては表皮細胞内で多量に産生されたPAが、細胞外に存在するプラスミノーゲンをプラスミンに転換し、このプラスミンが細胞間結合物質を消化することにより細胞間に組織液が貯留して表皮内水疱が形成されることが、in vitroの実験系のおいて明らかにされている(Morioka S. et al., "J. Invest. Dermatol.";76,1981)。
【0004】
【発明が解決しようとする課題】
本発明者は、上記事情に鑑み鋭意研究を重ねた結果、プラスミンやプラスミノーゲンアクチベーターの活性変化に起因する種々の皮膚疾患、肌荒れ、荒れ性等の改善・予防には抗プラスミン剤が有効であると考え、広く種々の物質について抗プラスミン活性を調べた結果、特定の植物抽出物が優れた抗プラスミン活性を有していることを見出し、本発明を完成するに至った。
【0005】
【課題を解決するための手段】
すなわち本発明は、セイヨウカラハナソウ(ホップ)(Humulus lupulus)、ローマカミツレ(Anthemis nobilis)の中から選ばれる1種または2種の植物またはその抽出物からなる、抗プラスミン剤に関する。
【0006】
本発明者が知る限りにおいて、上記植物抽出物の抗プラスミン活性についての報告はこれまでなされていない。
【0007】
【発明の実施の形態】
以下、本発明について詳述する。
【0008】
本発明の抗プラスミン剤は、セイヨウカラハナソウ(ホップ)(Humulus lupulus)、ローマカミツレ(Anthemis nobilis)の中から選ばれる1種または2種の植物またはその抽出物からなる。
【0010】
セイヨウカラハナソウ(ホップ)( Humulus lupulus )は、クワ科(Moraceae)カナムグラ属(Humulus)に属する植物である。
【0012】
ローマカミツレ( Anthemis nobilis )は、キク科(Compositae)カミツレモドキ属(Anthemis)に属する植物である。ヨーロッパ南部原産の多年草で、各地で薬用植物、切花用に栽培されている。
【0013】
上記各植物はそれぞれ、生のままでも乾燥したものでも使用することができるが、使用性、製剤化等の点から乾燥粉末あるいは溶媒抽出物として用いることが好ましい。
【0014】
これら各植物の使用部位としては、樹皮、全草、または葉、花、根等、任意に用いられ得るが、セイヨウカラハナソウ(ホップ)では果穂が、ローマカミツレでは花が、それぞれ特に抗プラスミン活性が強いことから、好適に用いられる。
【0015】
上記各植物の抽出物は常法により得ることができ、例えば、各植物をそれぞれ抽出溶媒とともに浸漬または加熱還流した後、濾過し濃縮して得ることができる。抽出溶媒としては、通常抽出に用いられる溶媒であれば任意に用いることができ、例えば、水、メタノール、エタノール、プロピレングリコール、1,3−ブチレングリコール、グリセリン等のアルコール類、含水アルコール類、クロロホルム、ジクロルエタン、四塩化炭素、アセトン、酢酸エチル、ヘキサン等の有機溶媒を、それぞれ単独あるいは組み合わせて用いることができる。上記溶媒で抽出して得た抽出液をそのまま、あるいは濃縮したエキスを吸着法、例えばイオン交換樹脂を用いて不純物を除去したものや、ポーラスポリマー(例えばアンバーライトXAD−2)のカラムにて吸着させた後、メタノールまたはエタノールで溶出し、濃縮したものも使用することができる。また分配法、例えば水/酢酸エチルで抽出した抽出物等も用いられる。
【0016】
このようにして得た上記植物抽出物は、安全性が高く、優れた抗プラスミン活性を有する。
【0017】

【0019】
上記抗プラスミン剤を皮膚外用剤に用いる場合、上記各植物抽出物に加えて、本発明の効果を損なわない範囲内で、通常化粧品や医薬品等の皮膚外用剤に用いられる他の成分、例えば保湿剤、酸化防止剤、油性成分、紫外線吸収剤、乳化剤、界面活性剤、増粘剤、アルコール類、粉末成分、色材、水性成分、水、各種皮膚栄養剤等を必要に応じて適宜配合することができる。
【0020】
さらに、エデト酸二ナトリウム、エデト酸三ナトリウム、クエン酸ナトリウム、ポリリン酸ナトリウム、メタリン酸ナトリウム、グルコン酸、リンゴ酸等の金属封鎖剤、カフェイン、タンニン、ベラパミル、トラネキサム酸およびその誘導体、甘草抽出物、グラブリジン、カリンの果実の熱水抽出物、各種生薬、酢酸トコフェロール、グリチルリチン酸およびその誘導体またはその塩等の薬剤、ビタミンC、アスコルビン酸リン酸マグネシウム、アスコルビン酸グルコシド、アルブチン、コウジ酸等の美白剤、グルコース、フルクトース、マンノース、ショ糖、トレハロース等の糖類なども適宜配合することができる。
【0021】
また、本発明を皮膚外用剤に用いる場合、外皮に適用される化粧料、医薬品、医薬部外品、特に好適には化粧料に広く適用することが可能であり、その剤型も、皮膚に適用できるものであればいずれでもよく、溶液系、可溶化系、乳化系、粉末分散系、水−油二層系、水−油−粉末三層系、軟膏、ゲル、エアゾール等、任意の剤型が適用される。
【0022】
また、その使用形態も任意であり、例えば化粧水、乳液、クリーム、パック等のフェーシャル化粧料やファンデーションの他、メーキャップ化粧料、芳香化粧料、浴用剤等に用いることができる。
【0023】
なお、上記の剤型および使用形態に本発明の抗プラスミン剤が採り得る形態が限定されるものではない。
【0024】
【実施例】
次に、実施例を挙げて本発明をさらに詳細に説明するが、本発明の技術的範囲はこれら実施例によってなんら限定されるものでない。なお、配合量はすべて重量%である。

BACKGROUND OF THE INVENTION
The present invention relates to an antiplasmin agent. More specifically, the present invention relates to an antiplasmin agent having an excellent antagonistic action on the activity of plasmin and plasminogen activator (PA). The present invention is applied to preparations for improving various diseases in which plasmin and PA activity changes are observed, and in particular, contact dermatitis, psoriasis, pemphigus vulgaris, congenital diseases in which the plasmin and PA activity changes are observed in affected areas. In addition to various skin diseases such as chicken pox, it is advantageously applied to an external preparation for skin having an excellent improvement and preventive effect on rough skin caused by drying, cleaning agents, and the like.
[0002]
[Background Art and Problems to be Solved by the Invention]
Conventionally, various therapeutic agents, external preparations for skin, cosmetics, and the like are known as having an effect of improving / preventing skin diseases and rough skin. In these conventional drugs and cosmetics, in addition to anti-inflammatory agents, amino acids, polysaccharides, lipids, and the like as active ingredients, various animal and plant extract extracts having anti-inflammatory activity or high moisturizing activity are used for skin inflammation and stratum corneum. It has been used because of its excellent ability to prevent the loss of moisture. However, in any case, the effect of improving and preventing rough skin is not always sufficient, and the development of a better medicinal agent has been expected.
[0003]
On the other hand, it is thought that proteolytic enzymes (proteases) in epidermal cells play an important role in the normal keratinization process of the skin (Ogawa H., Yoshiike T., "Int. J. Dermatol 23, 1984), in recent years, the changes in the activity of proteases related to fibrinolytic systems such as plasmin and plasminogen activator (PA) have been deeply involved in the pathogenesis of various skin diseases. It is being revealed that PA is a protease that specifically acts on plasminogen, the precursor of plasmin, and converts it to active plasmin. Regarding the relationship between this PA and skin diseases, for example, in psoriasis, which is representative of inflammatory abnormal keratotic diseases, strong PA activity exists at the complexed keratinized site of the affected skin (Haustein, “Arch. Klin. Exp. Dermatol. "; 234,1969) and reports that PA was extracted from psoriasis scales using a high-concentration salt solution (Fraki, Hopsu-Havu," Arch. Dermatol. Res "; 256, 1976). ing. In pemphigus vulgaris, PA produced in large amounts in the epidermis cells converts plasminogen present outside the cell into plasmin, and this plasmin digests the intercellular binding substance, thereby interstitial tissue fluid. It has been clarified in an in vitro experimental system (Morioka S. et al., "J. Invest. Dermatol."; 76, 1981) that epidermis blisters are formed.
[0004]
[Problems to be solved by the invention]
As a result of intensive studies in view of the above circumstances, the present inventors have found that antiplasmin agents are effective in improving / preventing various skin diseases, rough skin, rough skin, etc. caused by changes in the activity of plasmin and plasminogen activator. As a result, as a result of examining antiplasmin activity for various substances widely, it was found that a specific plant extract has excellent antiplasmin activity, and the present invention was completed.
[0005]

This solid was dissolved in dimethyl sulfoxide (DMSO) to make a 3% solution. The following experiment was conducted using this.
[0028]
(2) Measurement of antiplasmin activity The percent inhibition was determined by the fibrin plate method. That is, 6 mL of veronal buffer solution containing 1.0% plasminogen-removed fibrinogen (25 mmol / L sodium barbitalate aqueous solution containing 0.125 mol / L-NaOH, pH 7.4) was poured into a 9 cmφ petri dish. 0.0 mL / L-CaCl 2 and 0.2 mL of 25 U / mL thrombin 0.1 mL were added and gently mixed, and left for 1 hour. On a plate formed by changing fibrinogen to fibrin, a mixture obtained by mixing 5 U / mL of plasmin and a test substance in a ratio of 29: 1 was kept at 37 ° C. for 10 minutes, and then 20 μL was added. And left for 18 hours. As a control, the same operation was performed using DMSO instead of the test sample, and then the area of the dissolution circle formed by dissolving fibrin was measured, and the plasmin inhibition rate was determined by the following formula 1. The results are shown in Table 1.
[0029]
[Expression 1]
Inhibition rate (%) = [ 1- (dissolution circle area of test sample / dissolution circle area of control) ] × 100
Further, as a comparative product, the same test as described above was performed on an ethanol extract of a pomegranate (Pumica granatuum) fruit (JP-A-8-12586, etc.) known to have a high antiplasmin activity. . The results are also shown in Table 1.
