【発明が属する技術分野】
本発明は、結合組織の構成タンパク質であるコラーゲンを特異的に切断し、皮膚の老化,骨粗しょう症等の代謝性疾患,炎症性疾患,リューマチ関節炎,骨関節炎等の関節性疾患などの緩和,治療に副作用なく安全に使用し得るコラゲナーゼ阻害剤に関する。さらに詳しくは、ジカルボン酸或いはこれと金属キレート剤を含有して成るコラゲナーゼ阻害剤に関する。
【0002】
【従来の技術】
コラーゲンは動物の結合組織を構成する主要タンパク質であり、種々の組織においてI型〜XIII型の13種類の存在が知られている。コラゲナーゼは、かかるコラーゲンタンパク質を特異的に切断する酵素であり、加齢や紫外線による皮膚のしわの発生や粘弾性の低下、骨粗しょう症等の代謝性疾患、表皮水疱症,角膜潰瘍,歯根病等の炎症性疾患、リューマチ関節炎,骨関節炎等の関節性疾患など、実に幅広く多くの疾患に関与する。
【0003】
従って、コラゲナーゼ活性を阻害することにより、上記のような疾患を緩和或いは治療する試みが多くなされており、コラゲナーゼ阻害剤として、羊膜由来物質(特開平6−345636),ソバ殻タンパク質抽出物(国際公開9420541),ケイガイ,ハッカ抽出物(特開平6−183990),水溶性糖誘導体(特開平6−183941),ラクトフェリン(特開平5−186368),コーヒー酸又はその塩(特開平5−117145),アスコルビン酸,エリソルビン酸及びこれらの塩の混合物(特開平4−290819),アセチルポリアミド(フランス国特許2669629),ガロタンニン(特開平4−66524),κ-カゼイン(特開平4−41417),カカオ殻の抽出物(特開平3−44331),ヒドロキサム酸テトラペプチド(特開平1−160997),1,3-ビス-置換-ナフチルアミノカルボニルフェニル尿素誘導体(特公昭63−8101)などが開示されている。
【0004】
また、コラゲナーゼは金属プロテアーゼであるため、ディフェロキサミン(deferoxamine),エチレンディアミン四酢酸(ethylenediamine tetraacetic acid,EDTA)塩,酒石酸,クエン酸等の金属キレート剤もコラゲナーゼ阻害剤として用いられる。
【0005】
しかしながら、少量で高い阻害活性を示し、しかも副作用が少なくさらに安定性の高いコラゲナーゼ阻害剤としては、いまだに満足なものが得られていないのが現状である。
【0006】
【発明が解決しようとする課題】
そこで、本発明は少量の適用で高いコラゲナーゼ阻害活性を示し、しかも副作用がなく安全で、さらに種々の製剤基剤中で安定性が高く、いろいろな剤型の医薬品や化粧料等に応用することのできるコラゲナーゼ活性阻害剤を得ることを目的とする。
【0007】
【課題を解決するための手段】
上記の課題を解決するため、種々の物質のコラゲナーゼ阻害活性をスクリーニングした結果、ジカルボン酸類がやはり金属キレート作用を有し、しかも生体に対する作用が穏和で副作用がほとんどなく、また種々の形態の基剤中で安定であることを見い出し、本発明を完成するに至った。
【0008】
本発明においては、ジカルボン酸より1種又は2種以上を選択して基剤に配合する。ジカルボン酸としては、グルタル酸,アジピン酸,ピメリン酸,スベリン酸,アゼライン酸,セバシン酸,1,9-ノナメチレンジカルボン酸,1,10-デカメチレンジカルボン酸の炭素数5〜12の飽和二塩基酸が特に好ましい。配合量としては、製剤全量に対して0.01重量%〜10.0重量%程度が適当である。
【0009】
また、ジカルボン酸の1種又は2種以上に加えて金属キレート剤の1種又は2種以上を併用すると、コラゲナーゼ阻害活性が相乗的に増強される。金属キレート剤としては、ディフェロキサミン(deferoxamine),エチレンジアミン四酢酸(ethylenediamine tetraacetic acid,EDTA)のナトリウム塩,リン酸,クエン酸,アスコルビン酸,コハク酸,グルコン酸,ポリリン酸ナトリウム,メタリン酸ナトリウム等が挙げられ、これらより1種又は2種以上を選択して配合する。
【0010】
【作用】
本発明のコラゲナーゼ阻害剤は、少量の添加で優れたコラゲナーゼ阻害作用を示し、且つ生体に対する作用が穏和で、製剤中における安定性にも優れる。その結果、本発明のコラゲナーゼ阻害剤の適用により、加齢や紫外線による皮膚のしわの発生や粘弾性の低下、骨粗しょう症等の代謝性疾患、表皮水疱症,角膜潰瘍,歯根病等の炎症性疾患、リューマチ関節炎,骨関節炎等の関節性疾患などを緩和或いは治療することができ、また、創傷の治癒をも促進する。
【0011】
一例として、アゼライン酸のコラゲナーゼ阻害作用について以下に示す。コラゲナーゼを最終濃度で0〜15μg/ml含む水溶液に、アゼライン酸を最終濃度が8mM及び16mMとなるように加え、次いでフルオレセインイソチオシアネート(FITC)標識を行ったコラーゲンを最終濃度40μg/mlとなるように加えて、37℃で1時間インキュベーションした。エタノール添加により酵素反応を停止させた後、未反応のFITC標識コラーゲンを除去するため遠心分離を行い、上清中の蛍光強度を励起波長495nm,蛍光波長520nmで測定した。アゼライン酸を含まない溶媒のみを添加した系についても同様に蛍光強度を測定し、対照とした。結果は表1に示す。

[0004]
Further, since collagenase is a metalloprotease, metal chelating agents such as deferoxamine, ethylenediamine tetraacetic acid (EDTA) salt, tartaric acid and citric acid are also used as collagenase inhibitors.
[0005]
However, at present, satisfactory collagenase inhibitors that exhibit high inhibitory activity in a small amount and that have few side effects and high stability have not yet been obtained.
[0006]
[Problems to be solved by the invention]
Therefore, the present invention shows high collagenase inhibitory activity in a small amount of application, is safe with no side effects, is highly stable in various preparation bases, and is applied to pharmaceuticals and cosmetics of various dosage forms. It is an object of the present invention to obtain a collagenase activity inhibitor.
[0007]
[Means for Solving the Problems]
As a result of screening collagenase inhibitory activity of various substances in order to solve the above-mentioned problems, dicarboxylic acids still have a metal chelating action, have a mild action on living organisms, have almost no side effects, and have various forms of bases. The present invention was found to be stable, and the present invention was completed.
[0008]
In this invention, 1 type (s) or 2 or more types are selected from dicarboxylic acid and it mix | blends with a base. Dicarboxylic acids include glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, 1,9-nonamethylenedicarboxylic acid, 1,10-decamethylenedicarboxylic acid saturated dibasic having 5 to 12 carbon atoms. Acid is particularly preferred. As a compounding quantity, about 0.01 to 10.0 weight% is suitable with respect to the formulation whole quantity.
[0009]
Further, when one or more metal chelating agents are used in combination with one or more dicarboxylic acids, the collagenase inhibitory activity is synergistically enhanced. Examples of metal chelators include deferoxamine, sodium salt of ethylenediamine tetraacetic acid (EDTA), phosphoric acid, citric acid, ascorbic acid, succinic acid, gluconic acid, sodium polyphosphate, sodium metaphosphate, etc. 1 type or 2 types or more are selected and blended.
[0010]
[Action]
The collagenase inhibitor of the present invention exhibits an excellent collagenase inhibitory action when added in a small amount, has a mild action on the living body, and is excellent in stability in the preparation. As a result, by applying the collagenase inhibitor of the present invention, skin wrinkles and viscoelasticity due to aging and ultraviolet rays, metabolic diseases such as osteoporosis, inflammation such as epidermolysis bullosa, corneal ulcer, and root disease It can relieve or treat arthritic diseases, arthritic diseases such as rheumatoid arthritis, osteoarthritis, etc., and also promotes healing of wounds.
[0011]
As an example, the collagenase inhibitory action of azelaic acid is shown below. Azelaic acid is added to an aqueous solution containing collagenase at a final concentration of 0 to 15 μg / ml so that the final concentrations are 8 mM and 16 mM, and then fluorescein isothiocyanate (FITC) -labeled collagen is added to a final concentration of 40 μg / ml. In addition, it incubated at 37 degreeC for 1 hour. After stopping the enzyme reaction by adding ethanol, centrifugation was performed to remove unreacted FITC-labeled collagen, and the fluorescence intensity in the supernatant was measured at an excitation wavelength of 495 nm and a fluorescence wavelength of 520 nm. For the system to which only a solvent containing no azelaic acid was added, the fluorescence intensity was measured in the same manner as a control. The results are shown in Table 1.
[0012]
[Table 1]
Figure 0003854326
Table 1 also shows the collagenase inhibition rate determined by the formula (1). From this, it was shown that azelaic acid suppresses the release of FITC by collagenase to about 48 to 58% at 8 mM and to about 28 to 31% at 16 mM. That is, the collagenase inhibition rate increased depending on the concentration of azelaic acid, and reached 41.5 to 52.3 at 8 mM and 68.9 to 71.8% at 16 mM.

About the Example of said this invention, the healing effect with respect to an inflammatory ulcer was evaluated. An inflammatory ulcer was caused by treatment with a surfactant on the back of 5 mice. A sample was applied to this site twice a day at a dose of 0.5 g for 7 days, and the ulcer healing status after 7 days was observed. The healing situation was evaluated in three stages of “complete healing”, “almost healing”, and “incomplete healing”, and the number of mice that obtained each evaluation was shown. In Tables 2 to 4, Comparative Examples 1 to 3 were prepared using dicarboxylic acid as gallotannin and ascorbic acid as a chelating agent, respectively.
[0018]
In addition, the stability and skin irritation when the preparation was stored at 25 ° C. for 3 months were also evaluated. Storage stability was evaluated as “◯: no change in state”, “Δ: slight discoloration or separation of components”, “×: significant discoloration or separation of components”, Skin irritation was evaluated by calculating a skin irritation index according to the criteria shown in Table 5 by a 48-hour occlusion patch test by 20 male panelists, and calculating an average value of 20 persons. The above results are summarized in Table 6.
