Abstract：
:To find novel depigmenting agents, a new synthetic compound, N-adamantyl-3,4-dihydroxybenzamide (NADB) was produced and the effects on melanogenesis were investigated. Our results showed that NADB reduced melanin synthesis in a dose-dependent manner in melan-a cells. Tyrosinase activity was also reduced by NADB treatment in melan-a cells. However, NADB did not inhibit tyrosinase activity directly in a cell-free system. Treatment of melan-a cells with NADB caused a marked decrease in protein and mRNA levels of tyrosinase along with tyrosinase-related protein 1 and dopachrome tautomerase. To determine whether NADB reduces skin pigmentation, the dorsal skin of brown guinea pigs was shaved and irradiated with UV for 3 weeks using a solar simulator. Then NADB (2 or 1% in propylene glycol:ethanol:water = 5:3:2) was applied topically twice daily for 4 weeks. Visual inspection and Fontana-Masson staining both demonstrated that NADB resulted in lower skin pigmentation and total epidermal melanin in comparison to vehicle-treated areas. These findings suggest that NADB is useful in the treatment of hyperpigmentation.
