Updated Scientific Opinion on the risks for animal and human health related to the presence of phomopsins in feed and food

EFSA Journal, Volume 24, Issue 11, November 2026.
Abstract The EFSA CONTAM Panel assessed the risks for animal and human health related to the presence of phomopsins in feed and food. Lupins are considered the main source of phomopsins. Since the previous CONTAM Panel 2012 Opinion on phomopsins, new studies investigated the structural diversity of phomopsins.

Induction of Methuosis in Breast Cancer Stem Cells by a Cobalt(III) Complex Evokes Immunotherapeutic Response

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
Cancer stem cells (CSCs) drive metastasis, relapse and resist conventional apoptosis‐inducing chemotherapies. We report a cobalt(III)‐cyclam complex with pyrene and diflunisal moieties that reduces the viability of breast CSCs at low micromolar concentrations.

Bioorthogonal Chemistry in Neurobiology: From Imaging to Proteomics

ChemBioChem, Volume 27, Issue 20, 28 October 2026.
This review highlights emerging strategies for labeling neuronal proteins, enabling visualization and quantitative analysis of their expression, localization, and dynamics. By combining genetic code expansion (GCE), metabolic labeling, and click chemistry‐based labeling, these approaches provide powerful routes to study proteins in specific cells and ...

Characterization and Crystal Structure Elucidation of the l‐Homoserine O‐Succinyltransferase MetXS From Cupriavidus necator H16

ChemBioChem, Volume 27, Issue 20, 28 October 2026.
This study reports the identification, heterologous production, and in vitro characterization of the homoserine O‐succinyltransferase from C. necator (CnMetXS). Several biochemical parameters, including the pH and temperature optima, thermostability, substrate scope, and kinetic parameters, are determined, and a high‐resolution X‐ray structure of ...

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 ...

Proton‐Coupled Electron Transfer in Reaction of Catecholamines: Experimental and Computational Approach

ChemPhysChem, Volume 27, Issue 19, 14 October 2026.
Experimentally determined rate constants, kinetic isotope effects, and thermodynamic activation parameters in a nonpolar solvent, as well as density functional theory computational analysis of intrinsic bond orbitals (IBOs) along the intrinsic reaction coordinate (IRC) path including the transition state (TS), suggest that hydrogen transfer from ...
