Oxidative DNA damage: Induction by fructose, in vitro, and its enhancement by hydrogen peroxide

2023, Mutation Research - Genetic Toxicology and Environmental MutagenesisMechanism of reactive oxygen species generation and oxidative DNA damage induced by acrylohydroxamic acid, a putative metabolite of acrylamide
2022, Mutation Research - Genetic Toxicology and Environmental MutagenesisCitation Excerpt :Fig. 3 shows the effects of ROS scavengers and bathocuproine on DNA damage induced by amidase-treated AA in the presence of Cu(II). DNA damage was not inhibited by the OH scavengers ethanol, mannitol, sodium formate and DMSO, while it was inhibited by methional, which scavenges a variety of ROS in addition to OH [26]. Catalase, which decomposes hydrogen peroxide (H2O2) [27], and bathocuproine, a Cu(I)-specific chelator [28], were also able to inhibit DNA damage.
Characterization of key aroma-active compounds in lychee (Litchi chinensis Sonn.)
2018, Journal of Food and Drug AnalysisCitation Excerpt :This was consistent with the sensory results showing the “tropical fruit” note received the second highest score among all the olfactory attributes. Moreover, methional has been reported to be the biosynthetic precursor of ethylene, a natural plant hormone [17]. Following methional, geraniol, furaneol, nerol, DMTS, linalool, (E,Z)-2,6-nonadienal and nerolidol also showed important influences on the aroma profile of ‘Sweetheart’ lychee.
Reactivity and stability of selected flavor compounds
2015, Journal of Food and Drug AnalysisOxidatively generated DNA damage after Cu(II) catalysis of dopamine and related catecholamine neurotransmitters and neurotoxins: Role of reactive oxygen species
2011, Free Radical Biology and MedicineCitation Excerpt :However, TBP, a well-known hydroxyl radical scavenger, with recently identified singlet oxygen [48] and hydroperoxyl [49] scavenging properties as well, was a moderate inhibitor (67%) of this oxidatively damaged DNA, suggesting that singlet oxygen and/or the hydroperoxyl radical, but not the hydroxyl radical, may mediate dopamine/Cu(II) oxidatively generated DNA damage. Methional, a hydroxyl radical scavenger and inhibitor of metal–oxygen complexes [50], substantially inhibited dopamine/Cu(II) oxidative product levels. The lack of efficacy of the classical hydroxyl radical scavengers tested suggests that methional is most probably scavenging a copper–peroxide complex that may be an important mediator of this oxidatively damaged DNA.
