Oxidation of Quercetin and Kaempferol Markedly Amplifies Their Antioxidant, Cytoprotective, and Anti-Inflammatory Properties

open access: yesAntioxidants, 2023
The contention that flavonoids’ oxidation would necessarily lead to a loss of their antioxidant properties was recently challenged by the demonstration that quercetin oxidation leads to the formation of 2-(3,4-dihydroxybenzoyl)-2,4,6-trihydroxy-3(2H ...

The Modus Operandi of Hydrogen Sulfide(H2S)-Dependent Protein Persulfidation in Higher Plants

open access: yesAntioxidants, 2021
Protein persulfidation is a post-translational modification (PTM) mediated by hydrogen sulfide (H2S), which affects the thiol group of cysteine residues from target proteins and can have a positive, negative or zero impact on protein function.
