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 ...

Chelation‐Assisted Metal‐Catalyzed Ligation and Cleavage Reactions for Chemical Biology

European Journal of Organic Chemistry, Volume 29, Issue 39, 22 October 2026.
Chelation‐assisted transition metal catalysis has emerged as a promising complement to bioorthogonal click chemistry for studying biological processes. By pre‐organizing catalytic metal centers, designed coordinating substrates enhance reactivity and biocompatibility, enabling site‐selective ligation and decaging reactions in complex biological media ...
