In vitro evaluation of copper-chelating properties of flavonoids

Abstrakt

26 flavonoids were analyzed for their copper chelating activity in this study by two different spectrophotometrical approaches. Some flavonoids, in particular 3-hydroxyflavone and kaempferol, were more potent than the clinically used copper chelator trientine.
