Heck- and Suzuki-coupling approaches to novel hydroquinone inhibitors of calcium ATPase

open access: yesBeilstein Journal of Organic Chemistry, 2019
In this study, we explored Heck- and Suzuki-coupling methodology to modify the template 2,5-di-tert-butylhydroquinone (BHQ, 2), an inhibitor of the enzyme sarco/endoplasmic reticulum calcium ATPase (SERCA).

Electrophilic Catalysis in Iodosylbenzene Oxidation of Aromatic Derivatives

open access: yesCHIMIA, 1986
The oxidation of activated aromatic compounds (phenols and hydroquinones) is catalyzed by BF3 or RuCl2(PPh3)3. The catalytic effect of the ruthenium is ascribed to electrophilic catalysis, due to complexation between iodosylbenzene and the Ru species ...

Sensitized photolysis of polychlorobiphenyls in alkaline 2-propanol: dechlorination of Aroclor 1254 in soil samples by solar radiation [PDF]

open access: yes, 1992
Photodechlorination of Aroclor 1254 (1000 mg/L) in an alkaline 2-propanol solution at \lambda = 254 nm proceeded with a high quantum yield (\phi = 35.0) as determined by C1- release.

Electrocatalytic Activity of Heteroatom-Doped Graphene for Oxidation of Hydroquinones

open access: yesElectrochemistry, 2020
In the present study, we aim to synthesize heteroatom (nitrogen or boron) doped-reduced graphene oxide (N-rGO or B-rGO) as a catalyst for the electro-oxidation of hydroquinones, used as a candidate of fuel (hydrogen carrier molecule) for direct-type fuel

On the Theory of Oxidation-Reduction Reactions Involving Electron Transfer. III. Applications to Data on the Rates of Organic Redox Reactions [PDF]

open access: yes, 1957
A recently developed theory of oxidation‐reduction reactions (Part I) is used to calculate the rates of organic redox reactions whose mechanism involves the transfer of an electron from one reactant to the other. The theory can be used to discuss factors

Oxidative stress in Duchenne muscular dystrophy: focus on the NRF2 redox pathway [PDF]

open access: yes, 2017
Oxidative stress is involved in the pathogenesis of Duchenne muscular dystrophy (DMD), an X-linked genetic disorder caused by mutations in the dystrophin gene and characterized by progressive, lethal muscle degeneration and chronic inflammation.

Machine Learning Accelerates Crystallization for Structure Determination

open access: yesAngewandte Chemie, EarlyView.
Single‐crystal x‐ray diffraction (SCXRD) is often constrained by the difficulty of obtaining suitable crystals. Here, a machine learning‐accelerated co‐crystal discovery workflow is established for a crystalline mate strategy that achieves over 95% prediction accuracy and experimentally delivers 114 co‐crystals from 120 candidates.
