Description

本発明は、新規スフィンゴシノイド及びそれを含有する皮膚外用剤に関する。  The present invention relates to a novel sphingosine and an external preparation for skin containing the same.

近年になって、肌荒れを主訴とする皮膚疾患が急増している。所謂アトピー性皮膚炎と総称されている皮膚疾患を含めると、全人口の10%以上にも達するとも言われている。その一因としては、環境の悪化や生活ストレスの過剰負荷などが取りただされている。この様な肌荒れに対しては、古くから存在する、保湿成分の付与であるとか、油性成分を用いた閉塞による水分散逸の抑制等のスキンケア手段はあまり有効ではなく、かかる成分を含有する化粧料を塗布する行為自体が刺激となり、新たな炎症を引き起こす場合もある。この様な人は、「敏感肌」に分類され、化粧料の使用の困難な人とされている。通常この様な敏感肌の人の、肌荒れの症状の改善のためには、プレドニゾロンやデキサメタゾンなどのステロイドが有効であると言われ、それらが用いられるが、これらステロイドの奏功率も40%前後であることが経験的に知られている。即ち、これらのステロイド剤による治療の効果が現れない場合には、この様な肌荒れについては打つ手がないと言わざるを得なかった。又、ステロイド剤の使用は、その副作用の可能性故に、厳密な医師のコントロール下で為される必要があり、その使用に於ける心理的圧迫は決して少なくないものであると言わざるを得ない。
一方、スフィンゴシンと呼ばれるアミノ基を有する長鎖アルケニル化合物は皮膚構成重要成分の一つであり、スフィンゴシンを保湿などの目的で、化粧料などの皮膚外用剤に含有させることは既に知られているが、後記一般式(1)及び(2)に表されるスフィンゴシノイド及びその塩は文献未記載の新規化合物であり、それらを皮膚外用剤に含有させることも、それが皮膚外用に投与した場合、真皮のコラーゲン線維束などの構造を変えることなく、散逸水分量を顕著に抑制することも全く知られていない。
In recent years, skin diseases with chief complaints of rough skin have been rapidly increasing. Including dermatological diseases collectively called so-called atopic dermatitis, it is said to reach 10% or more of the total population. One reason for this is the deterioration of the environment and the overload of life stress. For such rough skin, skin care means such as the application of a moisturizing ingredient or suppression of water dispersion due to occlusion using oily ingredients is not so effective, and cosmetics containing such ingredients The action itself of applying may become a stimulus and cause new inflammation. Such people are classified as “sensitive skin” and are difficult to use cosmetics. Usually, steroids such as prednisolone and dexamethasone are said to be effective in improving the symptoms of rough skin in people with such sensitive skin, and they are used, but the response rate of these steroids is around 40%. It is known from experience. In other words, if the effect of treatment with these steroids does not appear, it must be said that there is no way to deal with such rough skin. In addition, the use of steroids must be done under strict physician control because of the possible side effects, and it must be said that psychological pressure in their use is not limited. .
On the other hand, a long-chain alkenyl compound having an amino group called sphingosine is one of the important constituents of the skin, and it is already known that sphingosine is contained in a skin external preparation such as cosmetics for the purpose of moisturizing. The sphingosinoids and salts thereof represented by the following general formulas (1) and (2) are novel compounds that have not been described in the literature, and they can be contained in a topical skin preparation or applied to the skin. It is also not known at all to significantly suppress the amount of dissipated water without changing the structure of collagen fiber bundles of the dermis.
