Thiol-ene click synthesis of phenylboronic acid-functionalized covalent organic framework for selective catechol removal from aqueous medium.

ACS Applied Materials and Interfaces, 2019
We report a thiol-ene click strategy for the preparation of a novel phenylboronic acid-functionalized covalent organic framework (COF) for selective removal of catechol in aqueous solution. Vinyl-functionalized 2,5-diallyloxyterephthalaldehyde (Da-V) was

Adaptive control in lubrication, adhesion, and hemostasis by Chitosan-Catechol-pNIPAM.

Biomaterials Science, 2019
Bio-inspired wet adhesives attract considerable attention in the biomedical field. However, achieving reversible and controllable wet adhesion still remains a challenging issue. In this study, we report a new thermo-responsive polysaccharide wet adhesive

Catechol estrogen methylene ethers

Steroids, 1974
Abstract We have prepared 2-hydroxyestrone 2,3-methylene ether and 2-hydroxy-estradiol 2,3-methylene ether; these compounds were not found as urinary metabolites of radioactive estrone, estradiol or 2-methoxyestrone in humans.

Catechol derived from aronia juice through lactic acid bacteria fermentation inhibits breast cancer stem cell formation via modulation Stat3/IL‐6 signaling pathway

Molecular Carcinogenesis, 2018
Cancer stem cells (CSCs) as a subpopulation of cancer cells are drug‐resistant and radiation‐resistant cancer cells to be responsible for tumor progress, maintenance and recurrence of cancer, and metastasis.

Catechol Monoglyceryl Ether Carbamates

Journal of Pharmaceutical Sciences, 1963
Abstract A series of carbamates and N-methylcarbamates derived from 3-(o-hydroxyphen-oxy)-1,2-propanediol was prepared and screened for muscle relaxant activity. An ester interchange between the above diol and diethyl carbonate failed to give 4-(e-hydroxyphenoxymethyl)-1,3-dioxolone-2; 2-hydroxymethyl-1,4-benzodioxane was obtained instead.

Nucleophilic Deoxyfluorination of Catechols

Organic Letters, 2011
Nucleophilic deoxyfluorinaiton of one of the two hydroxyl groups of catechols has been developed via the Umpolung concept. This method was successively applied to naturally occurring catechols, such as catechins and dopamine, to produce novel fluorinated analogues.

A stain with catechol

Acta Histochemica, 1977
Summary When catechol, the simplest o-dihydroxy aromatic compound, is oxidized in the presence of potassium alum, there results a solution which stains very similarly to an alum hematoxylin.
