TÓM TẮT
The ability of a new compound, Wal, (walterolactone A/B 6-O-gallate-β-D-pyranoglucoside) originating from Euonymus laxiflorus Champ. as a hydroperoxyl radical scavenger and pro-oxidant enzyme inhibitor was studied in silico. Different mechanisms, reaction locations, and chemical species of Wal in aqueous solution were taken into consideration. Formal hydrogen transfer from the OH group has been discovered as the chemical process that contributes most to the antioxidant properties of Wal in nonpolar and aqueous solutions. The overall rate coefficients for polar and non-polar environments are expected to have values of 7.85 × 106 M−1 s−1 and 4.84 × 105 M−1 s−1, respectively. According to the results of the investigation, Wal has greater scavenging activity against the HOO˙ radical than the reference antioxidant Trolox at physiological pH (7.4). In addition, docking results indicate that Wal's antioxidant
