B16 Melanoma 세포에서 Arctigenin이 Tyrosinase 활성과 Melanin 생성에 미치는 영향

Abstract

To investigate the possibility of development as a whitening agent using arctigenin, we measured DPPH assay, NBT/XO assay, intracellular ROS scavenging assay, tyrosinase assay and MSH-induced melanin production in B16 melanoma cells. Arctigenin dose-dependently had anti-oxidant activity in DPPH, NBT/XO and intracellular ROS assay. Although arctigenin did not inhibit purified tyrosinase activity, it dose-dependently inhibited tyrosinase activity and melanin production in B16 melanoma cells stimulated by 1 μM α-MSH. In particular, arctigenin at a concentration 100 μM inhibited α-MSHstimulated tyrosinase activity and melanin production by 50.9±2.9% and 69.0±6.5% respectively. And typical tyrosinase inhibitor, arbutin, inhibited 57.7±2.9% and 65.1±5.0% respectively. Such an similar inhibitory effect of arctigenin and arbutin in B16 melanoma cells may be due to the inhibition of MSH signal pathway rather than the direct inhibition of tyrosinase. Therefore, these results suggest that arctigenin may be useful for the development as whitening agents.
