چکیده

2-Hydroxytyrosol (2-HT), originally reported as a synthetic compound, was isolated for the first time as a fungal metabolite. 2-HT was found to inhibit mushroom tyrosinase with an IC50 value of 13.0 µmol/L. Furthermore, 2-HT dose-dependently inhibited tyrosinase activity (IC50, 32.5 µmol/L) in the cell-free extract of B16 melanoma cells and α-melanocyte stimulating hormone (α-MSH)-stimulated melanin formation in intact B16 melanoma cells.

Inhibitory activity on tyrosinase and antioxidant activity of methanol extract of various aerial parts of Astragalus siliquosus Bioss. and Verbascum phoeniceum L.

Background:Melanogenesis begins with the oxidation of L-tyrosine to L-Dopa by tyrosinase. Inhibition of tyrosinase could be effective in treatment of complications such as skin lesions, eczema and melasma. Inhibition of tyrosinase could be effective in treatment of those complications. The aim of this study was to determine inhibitory activity on tyrosinase and antioxidant activity of Ast...

The inhibition effects of melon on mushroom tyrosinase activity

The  inhibition effects seed and peel of melon on diphenolase activity of mashroom tyrosinase were investigated. The IC50 values and Ki values of seed and peel of melon were evaluated. increased the Km value and decreased the Vm value so it show mixed type inhibition on mushroom tyrosinase when L-DOPA was used as a substrate.
