- Abstract
- Objectives The aim was to search for inhibitors of melanogenesis from natural
resources.
Methods The inhibitory effect of silymarin on melanogenesis in a spontaneously
immortalized mouse melanocyte cell line, Mel-Ab, was studied.
Key findings Silymarin significantly prevented melanin production in a dose-dependent
manner with an IC50 value (concentration producing 50%maximal inhibition) of 28.2 mg/ml,
without effects on cell viability. Also, silymarin inhibited L-DOPA oxidation activity of
tyrosinase, the rate-limiting melanogenic enzyme, in cell based-systems but it did not directly
affect cell-free tyrosinase activity. Furthermore,Western blot analysis indicated that silymarin
decreased the expression of tyrosinase protein.
Conclusions This study suggests that the depigmenting effect of silymarin might be
attributable to inhibition of tyrosinase expression and that silymarin may be useful as a
natural skin-lightening agent.
