Description
NGFの発現を抑制する成分として、レモングラス抽出物等が提案されている(特許文献1参照)。
一方、Sema3Aタンパク質を皮膚炎モデルマウスに皮内投与すると、皮疹が改善し掻痒性も低減することが報告されており(特許文献2参照)、Sema3Aの発現を促進する成分としてオウゴンエキス等が提案されている(特許文献3参照)。
また、本発明に係る敏感肌用皮膚外用剤は、前記神経成長因子発現抑制剤および/または前記セマフォリン3A発現促進剤を配合したことを特徴とする。
本実施形態の神経成長因子発現抑制剤およびセマフォリン3A発現促進剤は、ラベンダーからの抽出物を有効成分とするものである。
以上のようにして得られるラベンダー抽出物は、優れた神経成長因子(NGF)発現抑制作用およびセマフォリン3A(Sema3A)発現促進作用を有しているため、NGF発現抑制剤およびSema3A発現促進剤の有効成分として用いることができる。本実施形態のNGF発現抑制剤およびSema3A発現促進剤は、医薬品、医薬部外品、化粧品等、飲食品の幅広い用途に使用することができる。
また、本実施形態のNGF発現抑制剤またはSema3A発現促進剤の投与量は、疾患の種類、重症度、患者の個人差、投与方法、投与期間等によって適宜増減すればよい。
例えば、本実施形態のSema3A発現促進剤は、そのSema3A発現促進作用を通じ、破骨細胞の分化を抑制するとともに骨芽細胞の分化を促進し、骨量増加(骨保護)の用途に用いることができる。
上記実施形態に係るNGF発現抑制剤またはSema3A発現促進剤は、そのNGF発現抑制作用またはSema3A発現促進作用を利用して、敏感肌用の皮膚外用剤に配合することができる。敏感肌における痒みや痛みを予防、治療または改善する用途において、皮膚外用剤は特に好適な剤型である。ここで、本実施形態において用いられるNGF発現抑制剤および/またはSema3A発現促進剤としては、ラベンダー抽出物をそのままの形態で用いてもよく、ラベンダー抽出物から製剤化したNGF発現抑制剤またはSema3A発現促進剤を用いてもよい。
ラベンダー抽出物(試料1)について、以下のようにして神経成長因子(NGF)mRNA発現抑制作用およびセマフォリン3A(Sema3A)mRNA発現促進作用を試験した。
A:被験試料添加時の補正値
B:被験試料無添加時の補正値
NGF mRNA発現抑制率の結果を表1に示す。
A:被験試料添加時の補正値
B:被験試料無添加時の補正値
Sema3A mRNA発現促進率の結果を表2に示す。
また、表2に示すように、ラベンダー抽出物(試料1)は、優れたSema3A mRNA発現促進作用を有することが確認された。
