Relationships between structures of hydroxyflavones and their antioxidative effects

While the radical scavenging activity of galangin, 3,5,7-trihydroxyflavone was 52.5%, fisetin, 3,7,3′,4′-tetrahydroxyflavone showed 85.2%. To investigate the relationships between the structures of 30 hydroxyflavones and their antioxidative effects, the three-dimensional quantitative structure–activ...

Zusammenfassung:While the radical scavenging activity of galangin, 3,5,7-trihydroxyflavone was 52.5%, fisetin, 3,7,3′,4′-tetrahydroxyflavone showed 85.2%. To investigate the relationships between the structures of 30 hydroxyflavones and their antioxidative effects, the three-dimensional quantitative structure–activity relationships were examined. Even hydroxyflavones show diverse biological functions, they have two common features such as showing antioxidative effects and containing hydroxyl groups. The authors tested the antioxidative effects of thirty hydroxyflavones using 1,1-diphenyl-2-picrylhydrazyl radical scavenging assay. While the scavenging activity of galangin, 3,5,7-trihydroxyflavone was 52.5%, fisetin, 3,7,3′,4′-tetrahydroxyflavone showed 85.2%. To investigate the relationships between the structures of hydroxyflavones and their antioxidative effects, the three-dimensional quantitative structure–activity relationships were examined.
