Antioxidant properties of 3-hydroxycoumarin derivatives
A series of hydroxylated 3-hydroxycoumarins was synthesised and evaluated for their antioxidant properties. The compounds substituted on the C-7 position were almost as antioxidant as quercetin or vitamin C. The antioxidant properties were related by an EPR study to their abilities to give stable semiquinonic or polyhydroxylated radicals. A series of hydroxylated 3-hydroxycoumarins was synthesised by the reaction of 3-aryl-2-hydroxypropenoic derivatives with boron tribromide. They were evaluated for their ability to scavenge the 2,2-diphenyl-1-picrylhydrazyl radical, the superoxide anion radical, the hydroxyl radical and the peroxynitrite anion and to inhibit copper-induced human LDL peroxidation. The physicochemical results were in accordance to establish the compounds hydroxylated on C-6 and C-7 positions as the most active of the series with antioxidant potencies comparable to those of quercetin and vitamin C. These compounds form o- and p-quinonoid derivatives upon radical scavenging and may serve as new lead compounds for pharmacological investigations.
