摘要:
Galactosylceramide analogs represented by the following general formula (1) or (2): (1) (2) wherein X and Y represent each S or O; R 1 and R 2 represent each C 9−35 alkyl or alkenyl; and R 3 represents C 2−30 alkyl or alkenyl. Easily available β−glucocerebrosidase activators, external skin preparations and a method of activating β−glucocerebrosidase whereby the formation of a horny layer penetration barrier can be improved through the activation of β−glucocerebrosidase and, as result, it is expected that skin roughness can be ameliorated.
