【発明の属する技術分野】
本発明は、化粧料、ヒアルロン酸分解が生理的に正常時より亢進している乾皮症,乾せん,あれ肌,乾燥肌等に対し予防・治療効果が期待できるヒアルロン酸分解阻害剤及び治療剤、並びにあれ肌又は乾燥肌防止剤に関する。
【0002】
【従来の技術】
ヒアルロン酸は、細胞間隙への水分の保持、組織内にジェリー状のマトリクスを形成することに基づく細胞の保持、臓器組織の潤滑性と柔軟性の保持、機械的障害等の外力への抵抗、及び細菌感染の防止等多くの機能を有している(BIOINDUSTRY、8巻、346頁、1991年)。
【0003】
さらに、近年ヒアルロン酸はその分子量によってさまざまな生理作用を持つことがわかってきた。例えば、生体内で合成されていると考えられている高分子ヒアルロン酸(分子量100万以上)はプロテオグリカン遊離抑制作用,ブラジキニン関節疼痛抑制作用,損傷軟骨修復作用,関節炎抑制作用を持つことから炎症抑制効果を持ち(BIO INDUSTRY、11巻、632頁、1991年)、その分解(低分子化)産物である低分子化ヒアルロン酸は、血管新生促進作用(Science,228巻,1324頁,1985年)、白血球走化性促進作用(特公平6─8323号公報)を持つことから炎症促進作用を持つと考えられている。そして老化による皮膚のヒアルロン酸の減少は皮膚の水分環境や柔軟性、張りやしわの形成に大きく関与していると考えられている(Int J Dermatol(1994),33,119−122)(Int J Dermatol(1996)35,539−544)。
【0004】
以上のことからヒアルロン酸の低分子化は肝炎,歯肉炎(炎症、4巻、437頁、1984年),関節リウマチ,変形性関節症(結合組織、25巻、243頁、1994年),悪性腫瘍(J.Cellar Physiology,160巻,275頁,1994 年)の症状悪化に密接に関連すると考えられ、さらに老化によるヒアルロン酸の減少は皮膚の張り減少、しわ形成にも関連し、従ってヒアルロン酸の低分子化を予防・防止するヒアルロン酸の分解阻害剤及び化粧料が望まれている。
【0005】
実際、結合組織中のヒアルロン酸を低分子化するヒアルロニダーゼが想定され、その阻害剤が薬理効果があることが期待された(炎症、4巻、437頁、1984年)。しかし、ヒト結合組織を形成する線維芽細胞からヒアルロニダーゼが単離された報告はいまだなく、そのためヒト線維芽細胞の酵素が牛精巣由来のヒアルロニダーゼと同様な性質を持っていると仮定し、牛精巣由来のヒアルロニダーゼを用いた種々の阻害剤が報告されている(特公平6─29271号公報、特公平6─4584号公報、特開平5─178876号公報、特開平6─80553号公報、特開平6─80576号公報、特開平6─9415号公報、特開平6─9416号公報、特開平3─68515号公報)のが現状である。
【0006】
しかし、近年、関節に存在するヒト滑膜細胞(結合組織、25巻、243頁、1994年),ヒト子宮けい管細胞(FEBS Letters,347巻, 95頁、 1994 年),ヒト皮膚線維芽細胞(B.B.A.,172巻, 70頁、 1990 年),ヒト肺線維芽細胞(J.Clin.Invest.90巻、1492頁、1992年)において、ヒアルロン酸を4糖、6糖にまで分解する牛精巣由来のヒアルロニダーゼとは明らかに異なるエンド型のヒアルロン酸分解機構の存在が報告されている。これらのことから精巣由来のヒアルロニダーゼの阻害剤ではヒトのヒアルロン酸分解を効果的に阻害することは困難である。
【0007】
【発明が解決しようとする課題】
従って本発明の目的とするところは、ヒアルロン酸分解が生理的に正常時より亢進している乾皮症,乾せん,あれ肌,乾燥肌等に対し予防・治療効果が期待でき、しかもヒトの線維芽細胞に直接作用し、優れた効果を発揮するヒアルロン酸分解阻害剤及び治療剤、並びにあれ肌又は乾燥肌防止剤を提供するにある。また、しわ防止や張り、柔軟性の改善等に効果のある化粧料を提供するにある。
【0008】
【課題を解決するための手段】
上記の目的は、クロカワ抽出物を含有又は有効成分とすることを特徴とする化粧料、ヒアルロン酸分解阻害剤、及びあれ肌又は乾燥肌防止剤、並びにヒアルロン酸異常分解疾患治療剤によって達成される。また、下記一般式(A)で示されるテルフェニル誘導体を含有又は有効成分とすることを特徴とする化粧料、ヒアルロン酸分解阻害剤、及びあれ肌又は乾燥肌防止剤によって達成される。即ち、本発明はクロカワ抽出物又は下記一般式(A)で示されるテルフェニル誘導体を含有又は有効成分とする化粧料、ヒアルロン酸分解阻害剤、及びあれ肌又は乾燥肌防止剤、並びにヒアルロン酸異常分解疾患治療剤にある。

【発明の実施の形態】
以下、本発明の実施の形態について詳説する。
【0011】
本発明に係るクロカワ抽出エキスを製造する方法としては、イボタケ科由来きのこであるクロカワ(Boletopsis Leucomelas )子実体を適当な抽出溶媒に一定期間浸漬すればよく、必要により減圧下還流抽出や加圧抽出等の通常の抽出手段を利用できる。例えば、クロカワ子実体凍結乾燥粉砕物に対し重量比で5〜30倍の抽出溶媒を加え、通常15〜50℃で24時間〜1週間浸漬して抽出エキスを得る方法等が挙げられる。
また、抽出エキスをろ過又は遠心分離等により不溶物を除去したり、通常の濃縮手段、例えば減圧濃縮等して濃縮抽出エキスとして得ることもできる。また通常の粉末化方法により乾燥エキス末として用いることもできる。
【0012】
クロカワの乾燥エキス末を製造する方法としては、前記抽出エキスを通常の乾燥手段、例えば減圧乾燥、噴霧乾燥又は凍結乾燥等により乾燥エキス末として得る方法等が挙げられる。
【0013】
クロカワ抽出エキスを製造する際に用いる抽出溶媒としては、例えば、水や、メタノール、エタノール、1,3ブチレングリコール等の水溶性有機溶媒、又はこれらの混合溶媒が挙げられる。更に酢酸エチル等の極性有機溶媒によって再抽出してもよい。または、クロロフォルム等の非極性溶媒処理によって疎水性物質を除いたあと上述した方法で濃縮、粉末化することもできる。
【0014】
本発明に係るテルフェニル誘導体は、例えば、上記のクロカワ抽出エキス又はその乾燥エキス末から得ることができる。
【0015】
本発明に係るテルフェニル誘導体を単離する方法としては、前記クロカワ抽出エキス又は乾燥エキス末を酢酸エチル等の有機溶媒で再抽出し、シリカゲルカラム等の分離手段で精製してテルフェニル誘導体画分として得る、又は更にシリカゲルカラム等の分離手段を繰り返したり、HPLCを用いて単離する方法等が挙げられる。
【0016】
本発明のヒアルロン酸分解阻害剤は、ヒアルロン酸分解が生理的に正常時より亢進している疾患に対して、優れた治療剤として用いることができ、また乾燥肌又はあれ肌防止剤としても用いられる。また、老化による皮膚の張り低下やしわの形成を予防する効果が期待できる。更には、通常の化粧品等の有効成分としての他、培養細胞系に添加して研究・試験用試薬等として用いることもできる。化粧料として用いる場合は、特に(頭皮を含む)皮膚に適用する皮膚化粧料が望ましい。尚、本発明において化粧料とは歯磨き、入浴剤をも包含するものである。歯磨きに用いた場合、歯肉炎の予防効果が期待できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cosmetic, a hyaluronic acid decomposition inhibitor and a therapeutic agent which can be expected to have a preventive / therapeutic effect on xerosis, psoriasis, irritated skin, dry skin, etc., in which hyaluronic acid degradation is physiologically increased from normal. And an agent for preventing rough or dry skin.
[0002]
[Prior art]
Hyaluronic acid retains water in the intercellular space, retains cells based on the formation of a jelly-like matrix in tissues, retains lubricity and flexibility of organ tissues, resists external forces such as mechanical obstacles, And many functions such as prevention of bacterial infection (BIOINDUSTRY, 8, 346, 1991).
[0003]
Furthermore, it has recently been found that hyaluronic acid has various physiological actions depending on its molecular weight. For example, high-molecular-weight hyaluronic acid (molecular weight of 1,000,000 or more), which is considered to be synthesized in vivo, suppresses proteoglycan release, suppresses bradykinin joint pain, repairs damaged cartilage, and suppresses inflammation. It has an effect (BIO INDUSTRY, Vol. 11, p. 632, 1991), and its degraded (low molecular weight) product, low molecular weight hyaluronic acid, has an angiogenesis promoting action (Science, 228, 1324, 1985). It has a leukocyte chemotaxis-promoting action (Japanese Patent Publication No. 6-8323) and is considered to have an inflammation-promoting action. It is considered that the decrease in hyaluronic acid in the skin due to aging is greatly involved in the moisture environment and flexibility of the skin, and the formation of tension and wrinkles (Int J Dermatol (1994), 33, 119-122) (Int). J Dermatol (1996) 35, 539-544).
[0004]
From the above, the low molecular weight of hyaluronic acid is considered to be due to hepatitis, gingivitis (inflammation, vol. 4, p. 437, 1984), rheumatoid arthritis, osteoarthritis (connective tissue, vol. 25, p. 243, 1994), malignancy It is thought to be closely related to the worsening of the symptoms of tumors (J. Cellar Physiology, 160, 275, 1994), and further, the decrease in hyaluronic acid due to aging is also associated with decreased skin tension and wrinkling, and thus hyaluronic acid. There is a need for hyaluronic acid degradation inhibitors and cosmetics that prevent and prevent the formation of low molecular weight compounds.
[0005]
In fact, hyaluronidase which reduces the molecular weight of hyaluronic acid in connective tissue was assumed, and it was expected that the inhibitor would have a pharmacological effect (Inflammation, Vol. 4, 437, 1984). However, there have been no reports of the isolation of hyaluronidase from fibroblasts that form human connective tissue.Therefore, it was assumed that the enzyme of human fibroblasts had properties similar to those of bovine testis-derived hyaluronidase. Various inhibitors using hyaluronidases derived from the same have been reported (JP-B-6-29271, JP-B-6-4584, JP-A-5-178876, JP-A-6-80553, JP-A-6-80553). At present, Japanese Patent Application Laid-Open Nos. 6-80576, 6-9415, 6-9416, and 3-65515.
[0006]
However, in recent years, human synovial cells present in joints (connective tissue, Vol. 25, p. 243, 1994), human cervical duct cells (FEBS Letters, 347, p. 95, 1994), human dermal fibroblasts (BBA, 172, 70, 1990) and human lung fibroblasts (J. Clin. Invest. 90, 1492, 1992) convert hyaluronic acid to tetrasaccharide and hexasaccharide. It has been reported that there is an endo-type hyaluronan-degrading mechanism that is clearly different from bovine testis-derived hyaluronidase, which degrades to the maximum. For these reasons, it is difficult for an inhibitor of testicular hyaluronidase to effectively inhibit the degradation of human hyaluronic acid.
[0007]
[Problems to be solved by the invention]
Therefore, an object of the present invention is to provide a preventive / therapeutic effect for xerosis, psoriasis, rough skin, dry skin, etc., in which hyaluronic acid degradation is physiologically higher than normal, and furthermore, human fiber It is an object of the present invention to provide a hyaluronic acid degradation inhibitor and a therapeutic agent which directly act on blast cells and exhibit excellent effects, and an agent for preventing rough or dry skin. Another object of the present invention is to provide a cosmetic that is effective in preventing wrinkles, improving tension, improving flexibility, and the like.
[0008]
[Means for Solving the Problems]
The above object is achieved by a cosmetic containing an extract of Kurokawa or as an active ingredient, a hyaluronic acid decomposition inhibitor, a rough skin or dry skin inhibitor, and a therapeutic agent for an abnormal hyaluronic acid degradation disease. . Further, the present invention is achieved by a cosmetic, a hyaluronic acid decomposition inhibitor, and a rough skin or dry skin inhibitor characterized by containing a terphenyl derivative represented by the following general formula (A) or as an active ingredient.
