The Cross‐Linking Mechanism and Applications of Catechol–Metal Polymer Materials
Advanced Materials Interfaces, 2021Catechol plays an important role in many systems by interacting with organic (e.g., amino acids) and inorganic (e.g., metal ions, metal oxides) compounds.

Reaction of estrone-3,4-o-quinone with ethanethiol and glutathione leads to the formation of 4-hydroxyestrone-2-thioethers. Incubations of [1-3H]hydroxyestrone with rat liver microsomes and NADPH in the presence of glutathione results in the formation of 4-hydroxyestrone-S-glutathione with no release of tritium in the water indicating GSH addition to C-

Abstract Catechol estrogens (CEs) are a major group of active natural estrogen metabolites, formed by aromatic hydroxylation of primary estrogens at either the C-2 or C-4 position. These compounds may participate in the mechanism of estrogen action on the brain and pituitary gland.

Catechol dioxygenases are key enzymes in the metabolism of aromatic rings by soil bacteria. Catechol dioxygenases have been found that participate in the metabolism of halogenated aromatic compounds and, in doing so, play a key role in bioremediation of halogenated pollutants.

Catechol-Mediated Glycidylation toward Epoxy Vitrimers/Polymers with Tunable Properties
Macromolecules, 2019This work demonstrates a series of epoxy vitrimers/polymers whose properties can be tuned by incorporating a catechol moiety as a part of the starting bisphenol motif.

Vibrational spectra of catechol, catechol-d2 and -d6 and the catecholate monoanion
Spectrochimica Acta Part A: Molecular Spectroscopy, 1991Abstract The Raman and infrared spectra of normal and deuterated catechol in the solid and aqueous solution phases are reported, together with data for the catecholate monoanion at high pH. Assignments of fundamental modes are proposed.

The catechol metabolites of estradiol, 2- and 4-hydroxyestradiol (2-OHE(2) and 4-OHE(2), respectively) are potent signaling molecules and are hypothesized to be central to estrogen-linked carcinogenesis. Methylation by catechol-O-methyltransferase (COMT) is the principal means of catechol estrogen (CE) deactivation in the liver and other tissues.

The Chemistry of Bioinspired Catechol(amine)-Based Coatings.
ACS Biomaterials Science & Engineering, 2019Surface coatings are widely used for the protection of underlying materials from erosion or contamination by the external environment, with biomimetic organic coatings based on catecholamine chemistry gaining prominence in recent years.
