Effect of 3,6-anhydro-l-galactose on α-melanocyte stimulating hormone-induced melanogenesis in human melanocytes and a skin-equivalent model.

ABSTRACT: 3,6-Anhydro-l-galactose (l-AHG) is a bioactive sugar that is a major component of agarose. Recently, l-AHG was reported to have anti-melanogenic potential in human epidermal melanocytes (HEMs) and B16F10 melanoma cells; however, its underlying molecular mechanisms remain unknown. At noncytotoxic concentrations, l-AHG has been shown to inhibit alpha-melanocyte-stimulating hormone-induced melanin synthesis in various cell models, including HEMs, melan-a cells, and B16F10 cells. Although l-AHG did not inhibit tyrosinase activity in vitro, reverse transcription-polymerase chain reaction results demonstrated that the anti-melanogenic effect of l-AHG was mediated by transcriptional repression of melanogenesis-related genes, including tyrosinase, tyrosinase-related protein-1 (TRP-1), tyrosinase-r
