Synthesis and characterization of amphiphilic nitroxide 1,1,3,3–tetraethylisoindoline–2–oxyl–5–sodium sulfonate (TEIOSNa)

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The synthesis and characterization of an amphiphilic nitroxide to be used as a controlling agent in a nitroxide‐mediated living radical polymerization in aqueous dispersion media is presented. In the first stage of nitroxide synthesis (phthalimide protection), two reaction methods were employed: traditional and microwave.

Investigating the Ligand‐Binding Properties of N‐arylbenzimidazoles as Novel Elastase Inhibitors

open access: yesChemMedChem, EarlyView.
A series of novel N‐[(3,5‐dimethylphenyl)methyl]‐1H‐benzimidazole derivatives is designed, synthesized, and evaluated for inhibitory activity against elastase. Several compounds demonstrate an antielastase activity, including the N‐(2‐bromophenyl)‐2‐(6‐chloro‐1‐(3,5‐dimethylbenzyl)‐1H‐benzo[d]imidazol‐2‐ylthio)acetamide, showing the greatest potency ...

From Light‐Driven to Dark Synthesis: Streamlining Perfluoroalkyl Selenide Ether Formation

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Two orthogonal and user‐friendly protocols enable the efficient construction of (Se/S)RF bonds from simple dichalcogenides and perfluoroalkyl iodides. Visible‐light irradiation at 395 nm promotes seleno‐ and thioether formation, while a dark KOH/MeCN variant delivers selenoethers in minutes. Both approaches operate under mild, metal‐ and photocatalyst‐

A Photoredox Radical‐Polar Crossover Reaction for the Preparation of Monoprotected Dicarbonyl Compounds

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
An ATRA‐based, Ru‐photocatalyzed radical‐polar crossover reaction for the preparation of monoprotected dicarbonyl compounds is reported. This procedure is based on the capture of a cationic intermediate, arising from the radical step, with diverse nucleophiles.

A2A Adenosine Receptor Agonists With Last‐Step Enzymatic 18F‐Labelling Potential (Fluorinase) for Positron Emission Tomography (PET)

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This study exploits the comparable binding tolerances between the fluorinase enzyme and the A2A adenosine receptor towards the development of novel C‐2 functionalised 5′‐fluorodeoxy‐adenosine (FDA)‐based agonists with enzymatic 18F‐labelling capability for positron emission tomography (PET).

Aloe vera Tannin Ameliorates Fructose‐Induced Dyslipidaemia and Oxidative Stress in Wistar Rats

open access: yesFood Chemistry International, EarlyView.
Aloe vera tannin (AVT) significantly enhances liver reduced glutathione and superoxide dismutase activities in rats. Fructose consumption creates dyslipidaemia in rats by significantly increasing serum cholesterol and LDL levels. AVT prevented fructose‐induced dyslipidaemia in rats by controlling the lipid profile. AVT did not affect liver, hippocampus
