【発明の属する技術分野】
本発明は、プリン誘導体及び/又はプリン誘導体を含有する植物抽出物の一種又は二種以上を含有し、紫外線曝露に起因する皮膚障害を抑制する皮膚障害抑制剤、または改善する皮膚障害改善剤、並びに、それらを有効成分として含有する皮膚外用剤に関するものである。更に、詳細には、プリン誘導体がテオフィリン、テオブロミン、カフェインからなる群より選ばれた一種又は二種以上である皮膚障害抑制剤又は皮膚障害改善剤に関するものであり、それらを有効成分として含有し、紫外線曝露に起因するシワ形成や皮膚腫瘍、皮膚肥厚、皮膚硬化を抑制、又は、形成若しくは発現した症状を改善する化粧品や医薬品として利用される有用な皮膚外用剤に関する。
【0002】
【従来の技術】
紫外線(太陽光)の連続的な長期間曝露は皮膚にケミカルメディエーター、サイトカイン等による炎症を生じせしめ、シワ、タルミ、皮膚肥厚、皮膚硬化、皮膚癌、日光性弾性線維症等の皮膚障害が生じる(非特許文献1参照)。特に表皮及び真皮が肥厚することにより、皮膚の弾性、保湿性が低下し、これが皮膚老化の要因の一つとなっていると考えられている。そこで、従来からこれらの障害を防ぐために、紫外線吸収剤(特許文献1、非特許文献2参照)、紫外線散乱剤(非特許文献3参照)が配合された外用剤、すなわち乳液、クリーム、ローション、美容液、ファンデーション、軟膏、パップ剤、貼付剤等が使用されている。
又、加齢、紫外線曝露等により生じる皮膚のシワやタルミ、ハリや弾力性の低下を予防、あるいは改善するために、レチノイン酸(非特許文献4参照)、抗炎症薬(非特許文献5参照)やコウボク、ボダイジュ、シソ等(特許文献2参照)、メリッサ抽出物等(特許文献3参照)が配合されている。
【0003】
しかしながら、例えば、レチノイン酸を配合した皮膚外用剤は、真皮上層にコラーゲンを増殖させシワ改善効果は有するが、シワの発生を抑制する効果はなく、塗布を中止すると元に戻ってしまい、また、塗布部位に紫外線が曝露すると却って皮膚癌を誘発する場合がある。他の紫外線吸収剤、紫外線散乱剤、抗炎症薬、植物抽出物等を配合した皮膚外用剤においても、シワ形成、皮膚腫瘍、皮膚肥厚等の抑制、改善効果が十分ではなかったり、効果を高めるためにこれらの添加物を高濃度に配合すると製剤の使用感が損なわれたり、高温時や経時で変質する等の問題が生じる場合があった。そこで、外用剤の剤型や使用感に影響を与えず、紫外線(太陽光)曝露によるシワ形成、皮膚腫瘍、皮膚肥厚及び皮膚硬化症等の皮膚障害の発現を防御する皮膚障害抑制剤、また、形成もしくは発現した皮膚障害を改善する皮膚障害改善剤、及びそれを含有する皮膚外用剤の開発が望まれていた。
【0004】
一方、プリン誘導体の化粧料への配合は既に知られているが、それらは痩身用や浴用に関するもの(特許文献4、5参照)であり、紫外線曝露に起因する皮膚障害、すなわち、シワ形成や皮膚腫瘍、皮膚肥厚、皮膚硬化の発現を抑制、また、形成若しくは発現した症状を改善することは今まで知られていなかった。

[試料塗布法と紫外線照射法]
1群8匹とし、紫外線照射90分前に上述の塗布試料をヘアレスマウス(10週齢)背中に塗布し、一定量の紫外線(東芝BLBランプ)を1日2時間(5回/週)15週間照射し(総照射量:716J/cm)、塗布試料の皮膚肥厚、皮膚腫瘍、シワ形成及び皮膚硬化症抑制効果を調べた。なお、対照としては、対照1(基剤のみ塗布し、紫外線非照射)、対照2(基剤のみ塗布し、紫外線照射)とした。
また、これらの試料の紫外線吸収スペクトルを測定し、これらは評価試験に影響を与えないことを確認した。
【0042】
(皮膚肥厚抑制効果)
紫外線照射前と紫外線照射15週後の皮膚の厚みをダイアル厚みゲージ(OZAK.MFG.CO.LTD.)を用い測定した。結果は、ヘアレスマウス8匹の皮膚厚みの平均値、及びその15週間後の増加率で評価した。
(皮膚腫瘍抑制効果)
皮膚腫瘍は径が0.5mm以上の腫瘍を発症したマウスの発生率(8匹中)で評価した。
(シワ形成抑制効果)
紫外線照射15週後のシワ形成について、下記表5に示す「光皮膚老化グレード」に基づいてシワグレードを判定した。なお、結果は、マウス8匹の評点の平均値で表し評価した。
(皮膚硬化症の発現抑制効果)
ヘアレスマウス皮膚背部中央部位を摘み、復元に5秒以上を要する皮膚を皮膚硬化症とし、マウス8匹中の発現率で評価した。

BACKGROUND OF THE INVENTION
The present invention includes one or more of a purine derivative and / or a plant extract containing a purine derivative, a skin disorder inhibitor that suppresses skin disorders caused by UV exposure, or a skin disorder ameliorating agent that improves, In addition, the present invention relates to an external preparation for skin containing them as active ingredients. More specifically, the present invention relates to a skin disorder inhibitor or a skin disorder ameliorating agent, wherein the purine derivative is one or more selected from the group consisting of theophylline, theobromine, and caffeine, and contains these as active ingredients. Furthermore, the present invention relates to a useful external preparation for skin that is used as a cosmetic or pharmaceutical agent that suppresses wrinkle formation, skin tumor, skin thickening, and skin sclerosis caused by ultraviolet exposure, or improves symptoms that are formed or expressed.
[0002]
[Prior art]
Long-term exposure to ultraviolet rays (sunlight) causes skin to become irritated by chemical mediators, cytokines, etc., resulting in skin disorders such as wrinkles, tarmi, skin thickening, skin sclerosis, skin cancer, and solar elastic fibrosis. (Refer nonpatent literature 1). In particular, thickening of the epidermis and dermis results in a decrease in skin elasticity and moisture retention, which is considered to be one of the causes of skin aging. Therefore, in order to prevent these obstacles conventionally, an external preparation containing an ultraviolet absorber (see Patent Document 1 and Non-Patent Document 2) and an ultraviolet scattering agent (see Non-Patent Document 3), that is, an emulsion, cream, lotion, Cosmetic liquids, foundations, ointments, cataplasms, patches, etc. are used.
In addition, retinoic acid (see Non-Patent Document 4), anti-inflammatory drug (see Non-Patent Document 5) in order to prevent or improve skin wrinkles, tarmi, elasticity and reduced elasticity caused by exposure to ultraviolet rays, etc. ), Koboku, Bodaiju, Perilla etc. (see Patent Document 2), Melissa extract and the like (see Patent Document 3).
[0003]
However, for example, a skin external preparation formulated with retinoic acid has an effect of improving wrinkles by growing collagen in the upper layer of the dermis, but has no effect of suppressing the generation of wrinkles, and returns to its original state when application is stopped, If the application site is exposed to ultraviolet rays, skin cancer may be induced. Even in the topical skin preparations containing other UV absorbers, UV scattering agents, anti-inflammatory agents, plant extracts, etc., the effect of suppressing or improving wrinkle formation, skin tumors, skin thickening, etc. is not sufficient or enhanced Therefore, when these additives are blended at a high concentration, the usability of the preparation may be impaired, and problems such as deterioration at high temperatures and over time may occur. Therefore, a skin disorder inhibitor that does not affect the dosage form and feeling of use of the external preparation and protects against the development of skin disorders such as wrinkle formation, skin tumors, skin thickening and sclerosis due to exposure to ultraviolet rays (sunlight), and Therefore, it has been desired to develop a skin disorder ameliorating agent that improves a formed or developed skin disorder and a skin external preparation containing the same.
[0004]
On the other hand, the incorporation of purine derivatives into cosmetics is already known, but they are related to slimming and bathing (see Patent Documents 4 and 5), and skin damage caused by UV exposure, that is, wrinkle formation and Until now, it has not been known to suppress the development of skin tumors, skin thickening, and skin sclerosis, and to improve the symptoms formed or developed.

(Skin thickening suppression effect)
The skin thickness before and 15 weeks after UV irradiation was measured using a dial thickness gauge (OZAK.MFG.CO.LTD.). The results were evaluated by the average skin thickness of 8 hairless mice and the rate of increase after 15 weeks.
(Skin tumor suppression effect)
Skin tumors were evaluated by the incidence (out of 8) of mice that developed tumors with a diameter of 0.5 mm or more.
(Wrinkle formation inhibitory effect)
For wrinkle formation after 15 weeks of ultraviolet irradiation, the wrinkle grade was determined based on the “light skin aging grade” shown in Table 5 below. In addition, the result was expressed and evaluated by the average value of the scores of 8 mice.
(Suppression effect of skin sclerosis)
The central part of the back of the hairless mouse skin was picked, and the skin requiring 5 seconds or more for restoration was regarded as scleroderma, and the expression rate in 8 mice was evaluated.
