Abstract

|
This study was performed to elucidated the inhibitory effects of 6,8-diprenylorobol on melanin synthesis by measuring the levels of cell viability, mRNA expression, tyrosinase activity, and melanin production in the B16F10 cell line. The effects of 6,8-diprenylorobol on tyrosinase-related protein 1 (TYRP1), TYRP2, tyrosinase (TYR), and microphthalmia-associated transcription factor (MITF) mRNA expression levels and melanin content were determined. Quantitative real-time RT-PCR shows that 6,8-diprenylorobol decreases the mRNA expression levels of TYRP1, TYRP2, TYR, and MITF in B16F10 cell line, resulting in lower levels of melanin production compared to α-MSH-treated B16F10 cells. Tyrosinase activity assays reveal that 6,8-diprenylorobol decreases melanin production in B16F10 cells. These results demonstrate the whitening effects of 6,8-diprenylorobol on B16F10 cells; thus, 6,8-diprenylorobol is a potent ingredient for skin whitening. Further research is needed on the mechanism of action of 6,8-diprenylorobol. Such research will benefit not only cosmetics, but also the health food and medical industries.
