Theoretical insights into the antiradical activity and copper-catalyzed oxidative damage of mexidol in the physiological environment

This dataset contains data from the calculations described in the paper: "Quan V. Vo*, Nguyen Thi Hoa, Mai Van Bay, Adam Mechler, Theoretical insights into the antiradical activity and copper-catalyzed oxidative damage of mexidol in the physiological environment. Royal Society Open Science. 2021. In this study, the hydroperoxyl radical scavenging activity of MD was studied to establish baseline antioxidant activity, followed by an investigation of the effect of MD on the copper-catalyzed oxidative damage in biological systems, using computational methods. It was found that MD exhibits moderate radical scavenging activity against HOO· in physiological environments. The activity in aqueous solution is defined by the single electron transfer mechanism of the anion state; however in nonpolar environments the formal hydrogen transfer pathway dominates at the O3-H bond. It was also confirmed that MD can chelate Cu (II), forming complexes that are much harder to reduce than free Cu (II): MD chelation completely quenches the Cu (II) reduction by ascorbic acid and suppresses the rate of reduction reaction by O2·- that are the main reductants of Cu (II) in biological environments. Therefore, MD exerts its anti- HO· activity primarily as an OIL-1 inhibitor.
