Cellular Membrane‐Targeted Europium(III) Probe for Selective and Time‐Resolved Detection of Peroxynitrite

Chemistry – A European Journal, Volume 32, Issue 40, 27 October 2026.
We report a cellular membrane‐targeted europium(III) probe, Eu.Chol, that enables selective, time‐resolved detection of peroxynitrite (ONOO−) at the cell membrane interface. Eu.Chol demonstrates efficient incorporation into liposomes and Jurkat cells, with minimal response to H2O2, establishing a modular platform for subcellular ONOO− sensing ...

Nickel‐Substituted Rubredoxin Undergoes Demetallation Upon Reaction With Nitric Oxide and Nitroxyl

ChemBioChem, Volume 27, Issue 19, 14 October 2026.
Rubredoxin is a thermally stable thiolate iron‐bound protein that can be prepared as a nickel‐substituted one. This nickel protein showed sensitivity to reaction with NO and HNO donors, causing its demetallation. Notably, these reactions exhibit spectroscopic profiles in the ultraviolet–visible and fluorescence with potential bioanalytical use.

Protein nitration in the artery wall: A contributor to cardiovascular disease?

Redox Biochemistry and Chemistry
Nitration is a well-established post-translational modification of selected free amino acids, as well as proteins, lipids and nucleic acids. Considerable evidence is now available for the formation of long-lived species containing an added –NO2 function ...

Quantitative analysis of the proteome and protein oxidative modifications in primary human coronary artery endothelial cells and associated extracellular matrix

Redox Biology
Vascular endothelial cells (ECs) play a key role in physiology by controlling arterial contraction and relaxation, and molecular transport. EC dysfunction is associated with multiple pathologies.
