The Influence of Catechols on the Magnetization of Iron Oxide Nanoparticles
Nanomaterials, 2023 In this study, MNPs were functionalized with pyrocatechol (CAT), pyrogallol (GAL), caffeic acid (CAF), and nitrodopamine (NDA) at pH 8 and pH 11. The functionalization of the MNPs was successful, except in the case of NDA at pH 11.

AbstractThis review introduces multifaceted mutual interactions between molecules containing a catechol moiety and aggregation‐prone proteins. The complex relationships between these two molecular species have previously been elucidated primarily in a unidirectional manner, as demonstrated in cases involving the development of catechol‐based inhibitors

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.

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.

Catecholates and mixed catecholate hydroxamates as artificial siderophores for mycobacteria
Biometals, 2004Different mono-, bis- or triscatecholates and mixed mono- or biscatecholate hydroxamates were synthesized as potential siderophores for mycobacteria. SiderOphore activity was tested by growth promotion assays using wild type strains and iron transport mutants of mycobacteria as well as Gram-negative bacteria.

Catechol‐Functionalized Polyolefins
Angewandte Chemie International Edition, 2020AbstractThe incorporation of comonomers during ethylene polymerization can efficiently modulate important material properties of the polyolefins. Utilizing bioresourced comonomers for the generation of high‐performance polyolefin materials is attractive from a sustainability point of view.

Inhibition of catechol-o-methyl transferase by catechols and polyphenols
Biochemical Pharmacology, 1973Abstract The effects of the polyphenolic decarboxylase inhibitor, N1-(d,l-seryl)-N2-(2,3,4-Trihydroxybenzyl)-hydrazine (RO4-4602), were compared with the effects of dopa and pyrogallol as inhibitors of catechol-o-methyl transferase (COMT). The apparent Km, for [3H]norepinephrine as the substrate was 0.36 mM.
