A COMPOSITION FOR INHIBITING THE C-KIT PROTEIN CONTAINING BENZIMIDAZOLE AMINE DERIVATES OR AMINOQUINOLINE DERIVATIVES

摘要

A composition comprising a benzimidazole amine derivative or an aminoquinoline derivative is provided to inhibit signaling of a cell in melanocyte with which a c-kit protein is involved so as to control the function of the melanocyte, thereby providing skin-whitening effect. The composition for inhibiting c-kit protein or skin-whitening comprises 0.0001-10 wt.% of a benzimidazole amine derivative such as 1-(4-methoxyphenyl)-N-(1-naphthalenylmethal)-1H-benzimidazole-5-amine represented by the formula(1) or an aminoquinoline derivative such as 2-amino-3-(3,4-dimethoxyphenyl)-quinoline represented by the formula(2).
