1
(wherein X and Y each represent S or O, R
1
and R
2
each represent an alkyl group or an alkenyl group each having 9 to 35 carbon atoms. R
3
represents an alkyl group or an alkenyl group each having 2 to 30 carbon atoms.)
It is provided a &bgr;-glucocerebrosidase activator which is easily available, and external skin preparations and a method of activating &bgr;-glucocerebrosidase, in which improvement in formation of horny layer transmission barrier is expected by activating &bgr;-glucocerebrosidase so that an improved effect in rough skin is also expected.
提供以下公式(1)或(2)所表示的类似半乳糖鞘氨醇:
其中,X和Y各代表S或O,R1和R2各代表一个有9到35个碳原子的烷基或烯基,R3代表一个有2到30个碳原子的烷基或烯基。提供了一种易于获取的β-葡糖鞘脂酶激活剂,以及激活β-葡糖鞘脂酶的外用皮肤制剂和方法,通过激活β-葡糖鞘脂酶,预期改善角质层传递屏障的形成,从而也预期改善皮肤粗糙的效果。
