Myricetin 3-galactoside

Myricetin 3-galactoside is a flavonoid that has been found in M. communis and has diverse biological activities. It inhibits xanthine oxidase in a cell-free assay when used at a concentration of 100 µg/ml. Myricetin 3-galactoside is cytotoxic to K562 cells (IC50 = 220 µg/ml) and inhibits hydrogen peroxide-induced malondialdehyde (MDA) formation in the same cells when used at concentrations of 110, 220, and 440 µg/ml. In vivo, myricetin 3-galactoside (0.26 and 0.78 mg/kg) reduces carrageenan-induced paw edema in wild-type but not nos2-/- mice. It also reduces formalin-induced paw licking in mice.Formal Name: 3-(beta-D-galactopyranosyloxy)-5,7-dihydroxy-2-(3,4,5-trihydroxyphenyl)-4H-1-benzopyran-4-one. CAS Number: 15648-86-9.
