【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(非特許文献1)。
【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(非特許文献2)、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(非特許文献3)、白血球走化性促進作用(特許文献1)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(非特許文献4、5)。
【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(非特許文献6),関節リウマチ,変形性関節症(非特許文献7),悪性腫瘍(非特許文献8)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(非特許文献9)。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(特許文献2〜9)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(非特許文献10),ヒト子宮けい管細胞(非特許文献11),ヒト皮膚線維芽細胞(非特許文献12),ヒト肺線維芽細胞(非特許文献13)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。

【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。
【0012】
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(質量)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。
【0013】
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。
【0014】
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。
【0015】
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。
【0016】
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。
【0017】
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。

【0021】
本発明における防止剤とは、ヒアルロン酸の分解が生理的に正常時より亢進している症状者に適用するもの、及び予防として正常人が適用するものをいい、ヒアルロン酸の分解が生理的に正常時より亢進している症状者が適用するのが特に好ましい。
【0022】
本発明の化粧料の形態としては、適当な賦形剤,担体,希釈剤を用いて、ゲル,クリーム,スプレー剤,貼付剤,ローション,パック類,乳液,パウダー,入浴剤(顆粒剤、液剤、粉末等)等、化粧品に一般に用いられている種々の剤形に調製することができる。

【0027】
また、本発明の化粧料、ヒアルロン酸分解阻害剤、ヒアルロン酸異常分解疾患治療剤、及びあれ肌又は乾燥肌防止剤におけるクロカワ抽出エキス、テルフェニル誘導体の配合量としては、対象とする疾患の種類、程度、患者の年齢、体重、及び性別等種々の要因により異なり一概には規定できないが、適用する組成物の総量を100g基準として、0.0001g〜1. 5gが好ましく、特に0.001g〜1gが好ましい。0.0001g未満では本発明の効果が得られない場合があり、1.5gを超えて配合しても配合量に見合った効果が得られない場合がある。尚、該抽出エキスにおいては上記数値は乾燥エキス末としての換算値を適用する。
【0028】
本発明のヒアルロン酸分解阻害剤、ヒアルロン酸異常分解疾患治療剤及びあれ肌又は乾燥肌防止剤の投与方法としては、経口又は非経口投与が可能である。

BACKGROUND OF THE INVENTION
The present invention relates to a cosmetic, a hyaluronic acid degradation inhibitor and a therapeutic agent that can be expected to have a prophylactic / therapeutic effect on xeroderma, psoriasis, rough skin, dry skin and the like in which hyaluronic acid degradation is physiologically enhanced from normal. , And that skin or dry skin prevention agent.
[0002]
[Prior art]
Hyaluronic acid retains moisture in the interstitial space, retains cells based on the formation of a jelly-like matrix in the tissue, maintains the lubricity and flexibility of organ tissue, and resists external forces such as mechanical failure, And has many functions such as prevention of bacterial infection (Non-patent Document 1).
[0003]
Furthermore, in recent years, it has 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 million or more), which is thought to be synthesized in vivo, has proteoglycan release inhibitory action, bradykinin joint pain inhibitory action, damaged cartilage repair action, and arthritis inhibitory action. Low molecular weight hyaluronic acid, which has an effect (Non-patent Document 2) and is a degradation (low molecular weight) product, has an angiogenesis promoting action (Non-Patent Document 3) and a leukocyte chemotaxis promoting action (Patent Document 1). It is thought to have inflammation-promoting action because it has. And it is thought that the reduction | decrease of the hyaluronic acid of the skin by aging is greatly concerned in the water | moisture environment of a skin, a softness | flexibility, and formation of a tension | tension and wrinkles (nonpatent literature 4, 5).
[0004]
From the above, low molecular weight of hyaluronic acid is closely related to worsening symptoms of hepatitis, gingivitis (Non-patent document 6), rheumatoid arthritis, osteoarthritis (Non-patent document 7), and malignant tumor (Non-patent document 8). Hyaluronic acid reduction due to aging is also related to skin tension reduction and wrinkle formation. Therefore, hyaluronic acid degradation inhibitors and cosmetics that prevent and prevent hyaluronic acid molecular weight reduction are desired. Yes.
[0005]
Actually, hyaluronidase that lowers the molecular weight of hyaluronic acid in connective tissue is assumed, and the inhibitor was expected to have a pharmacological effect (Non-patent Document 9). However, there has been no report that hyaluronidase has been isolated from fibroblasts that form human connective tissue, so it is assumed that the enzyme of human fibroblasts has properties similar to those of bovine testis-derived hyaluronidase. Various inhibitors using derived hyaluronidase have been reported (Patent Documents 2 to 9).
[0006]
However, in recent years, human synovial cells (Non-patent document 10), human uterine cervical canal cells (Non-patent document 11), human dermal fibroblasts (Non-patent document 12), human lung fibroblasts (non-patent document) present in joints. Patent Document 13) reports the existence of an endo-type hyaluronic acid degradation mechanism that is clearly different from bovine testis-derived hyaluronidase that degrades hyaluronic acid into tetrasaccharides and hexasaccharides. For these reasons, it is difficult to effectively inhibit human hyaluronic acid degradation with testicular-derived hyaluronidase inhibitors.

As a result, Kurokawa extract containing the terphenyl derivative of Examples 1 to 6, terphenyl derivative fraction, terphenyl derivative, in any drug, in a state in which the degradation of hyaluronic acid was promoted more than when no histamine was added. Inhibition of hyaluronic acid degradation was also observed. Further, it was found that the addition of glycyrrhizin, which is an inhibitor of bovine testis-derived hyaluronidase shown in Comparative Example 3, has no effect in this evaluation system, which is a human cell culture system.
