O2‐Mediated Cu‐Catalyzed Dehydrogenative Sulfilimination of Tyrosines and Bioactive Phenols

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
We report herein the mild O2‐mediated Cu‐catalyzed dehydrogenative sulfilimination of diverse bioactive phenols with simple sulfenamides. The bioconjugation of unmodified native peptides, in particular at their tyrosine units with the dehydrogenative phenochalcogenazination reaction, has attracted much attention lately due to potential click type ...

Eicosapentaenoic and Docosahexaenoic Acid Levels in Mouse Tissues After Intake of Echium and Ahiflower Oils Rich in Stearidonic and α‐Linolenic Acids

Lipids, Volume 61, Issue 3, Page 417-426, May 2026.
Dietary supplementation with stearidonic acid–rich Echium and Ahiflower oils increases EPA levels across multiple mouse tissues, while DHA responses remain tissue‐specific and limited, supporting the strategic use of plant‐based omega‐3 sources for EPA‐focused interventions. ABSTRACT Omega‐3 fatty acids (n‐3 FA), particularly eicosapentaenoic acid (EPA)

Lactobacillus plantarum P1-2 reduces cumene and linoleic acid hydroperoxide to the corresponding hydroxyls.

, 2020
(A) L. plantarum P1-2 was aerobically cultured in GYP medium, and the cells were incubated in 50 mM sodium phosphate (pH 7) containing 25 mM glucose and 3 mM cumene hydroperoxide for 1.5 h at 37°C. After the reaction, each metabolite was analyzed by HPLC

Selective Peroxidation and Externalization of Phosphatidylserine in Normal Human Epidermal Keratinocytes During Oxidative Stress Induced by Cumene Hydroperoxide [PDF]

, 2002
Reactive oxygen species not only modulate important signal transduction pathways, but also induce DNA damage and cytotoxicity in keratinocytes. Hydrogen peroxide and organic peroxides are particularly important as these chemicals are widely used in ...

Probucol prevents oxidative injury to endothelial cells.

Journal of Lipid Research, 1991
We evaluated the effect of the antioxidant, probucol, on the cytotoxic effects of oxidized low density lipoprotein (OX-LDL) or of cumene hydroperoxide (CumOOH) on cultured bovine endothelial cells (EC).

Neuronal loss of the pentose phosphate pathway in the living nervous system is causally linked to [NADPH] reduction and elevated oxidative stress

The Journal of Physiology, Volume 604, Issue 10, Page 3825-3842, 15 May 2026.
Abstract figure legend Using genetically encoded sensors for NADPH and H2O2 in the living Drosophila nervous system, neuron‐specific PPP knockdown is shown to result in reduced neuronal NADPH levels and elevated neuronal H2O2 levels and oxidative stress.

Age-Dependent Vulnerability to Oxidative Stress of Postnatal Rat Pyramidal Motor Cortex Neurons

Antioxidants, 2020
Oxidative stress is one of the main proposed mechanisms involved in neuronal degeneration. To evaluate the consequences of oxidative stress on motor cortex pyramidal neurons during postnatal development, rats were classified into three groups: Newborn ...
