alpha-Arbutin

alpha-Arbutin is a glycosylated hydroquinone that has been found in Ericaceae and has diverse biological activities. It inhibits tyrosinase in a cell-free assay (IC50 = 0.48 mM for the mouse enzyme) and the production of melanin in HMV-II melanoma cells when used at a concentration of 0.5 mM. alpha-Arbutin (100 µM) prevents increases in reactive oxygen species (ROS) induced by rotenone (Cay-13995) in SH-SY5Y neuroblastoma cells. It decreases locomotor deficits in a parkin-null transgenic Drosophila model of Parkinson's disease. alpha-Arbutin (30 mM) reduces postprandial plasma glucose levels in mice. It has also been used in the synthesis of alpha-glucosidase inhibitors. Formulations containing alpha-arbutin have been used in cosmetic products as skin lightening agents.Formal Name: 4-hydroxyphenyl alpha-D-glucopyranoside. CAS Number: 84380-01-8.
