Pro- and Anti-oxidant Properties of Redox-Active Catechol-Chitosan Films
Frontiers in Chemistry, 2019 Catechols are abundant in nature and are believed to perform diverse biological functions that include photoprotection (e.g., melanins), molecular signaling (e.g., catecholamine neurotransmitters), and mechanical adhesion (e.g., mussel glue).

Kinetic Study of the Oxidation of Catechols in the Presence of N-Methylaniline
Journal of Chemistry, 2013 The reactions of electrochemically generated o-quinones from oxidation of catechol and 4-methylcatechol as Michael acceptors with N-methylaniline as nucleophile have been studied using cyclic voltammetry.

Phenolic metabolites of anthocyanins modulate mechanisms of endothelial function [PDF]
, 2015 Anthocyanins are reported to have vascular bioactivity, however their mechanisms of action are largely unknown. Evidence suggests that anthocyanins modulate endothelial function, potentially by increasing nitric oxide (NO) synthesis, or enhancing NO ...

From catechol‐tocopherol to catechol‐hydroquinone polyphenolic antioxidant hybrids
Heteroatom Chemistry, 2018 AbstractMultidefence antioxidants represent a valuable solution for the protection against oxidative stress. From the planned synthesis of a catechol‐tocopherol hybrid, we isolated a catechol‐hydroquinone hybrid through a BBr3‐mediated benzochromene‐fluoren‐1‐ol transposition.
