Oxyresveratrol and resveratrol, with hydroxy substituted trans-stilbene structure, exert potent inhibitory effects on cyclooxygenase, rat liver mitochondrial ATPase activity, and tyrosinase. As the isosteres of oxyresveratrol, a new family of hydroxyl substituted phenyl-naphthalenes were synthesized to show excellent inhibition of

The 4'-(p-toluenesulfonylamino)-4-hydroxychalcone (TSAHC), which bears inhibitory chemotypes for both alpha-glucosidase and tyrosinase, was evaluated for tyrosinase activity and depigmenting ability relative to compounds designed to only target tyrosianse activity. TSAHC emerged to be a competitive reversible inhibitor of mushroom tyrosinase.
