The hydroperoxyl radical scavenging activity of sulfuretin: insights from theory.

ABSTRACT: Sulfuretin (SFR), which is isolated from Rhus verniciflua, Toxicodendron vernicifluum, Dahlia, Bidens tripartite and Dipterx lacunifera, is one of the most important natural flavonoids. This compound is known to have numerous biological activities; among these, the antioxidant activity has not been thoroughly studied yet. In this study, the hydroperoxyl scavenging activity of SFR was examined by using density functional theory calculations. SFR is predicted to be an excellent HOO^• scavenger in water at pH = 7.40 with k _overall = 4.75 × 10⁷ M^-1 s^-1, principally due to an increase in the activity of the anionic form following the single-electron transfer mechanism. Consistently, the activity of the neutral for
