A Spin-Labeled Derivative of Gossypol

open access: yesMolecules
Gossypol and its derivatives arouse interest due to their broad spectrum of biological activities. Despite its wide potential application, there is no reported example of gossypol derivatives bearing stable radical functional groups.

Enabling Quantitative Benchtop 13C NMR Spectroscopy in Fast Continuous Flow

open access: yesMagnetic Resonance in Chemistry, Volume 64, Issue 9, Page 758-767, September 2026.
Paramagnetic relaxation enhancement (PRE) accelerates polarization buildup in continuous‐flow benchtop 13C NMR spectroscopy by the use of an immobilized PRE agent. By combining PRE with PENDANT polarization transfer, weak 13C signals are enhanced even at high flow rates, enabling robust quantitative analysis of solvent mixtures under process‐relevant ...

Mito‐TEMPO Improves Post‐Thaw Quality and Fertilizing Capacity of Rooster Semen Cryopreserved in Beltsville Extender

open access: yesVeterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study reported the effect of Mito‐TEMPO on rooster semen quality cryopreserved in Beltsville extender. Semen diluted in extenders containing 10 or 100 µM of Mito‐TEMPO presented higher motility, average path velocity as well as membrane/acrosome integrity, mitochondrial activity, and fertility rate; and lower lipid peroxidation, apoptosis rate ...

Nitroxide malonate methanofullerene as biomimetic model of interaction of nitroxide species with antioxidants

open access: yesColloids and Surfaces B: Biointerfaces, 2015
Bis-nitroxide malonate methanofullerene (NO)2-MF was studied as a biomimetic model of reduction-oxidation activity with natural compounds-cytochrome c (cyt c), dihydroquercetin (DHQ), ascorbic acid (AA) and synthetic drug-1-(β-oxyethyl)-4,6-dimethyl-1,2-dihydro-2-oxopyrimidine (xymedon(®)).
