Tetrazine Ligation in Living Systems: Beyond Fast Kinetics to Effective Bioorthogonality

Chemistry – A European Journal, EarlyView.
Rapid reaction kinetics (k2) alone do not ensure successful tetrazine ligation in living systems. This review introduces ‘effective orthogonality’—focusing on chemical survival, availability, and encounter—as a practical framework. We highlight how bottlenecks shift from cellular sinks to in vivo delivery limits, offering design strategies for reliable

Bioorthogonal Synthetic Chemistry Enabled by Visible‐Light Photocatalysis

Angewandte Chemie
AbstractThe field of bioorthogonal chemistry has revolutionized our ability to interrogate and manipulate biological systems at the molecular level. However, the range of chemical reactions that can operate efficiently in biological environments without interfering with the native cellular machinery, remains limited.

Proteomics of Nitrotyrosine: Integrating Mass Spectrometry and Immunodetection in Redox‐Driven Pathology

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Nitrooxidative stress, driven by excess reactive nitrogen species like peroxynitrite, contributes to the pathogenesis of many chronic diseases. Among its molecular footprints, 3‐nitrotyrosine (3NT) has emerged as a biologically relevant marker of protein nitration.

Protocol to identify S-acylated proteins in hippocampal neurons using ω-alkynyl fatty acid analogs and click chemistry

STAR Protocols
Summary: S-acylation, commonly palmitoylation, is the addition of fatty acids to cysteines to regulate protein localization and function. S-acylation detection has been hampered by limited sensitivity and selectivity in low-protein, costly samples like ...

Cell surface imaging and bioorthogonal chemistry

, 2021
The labelling of the plasma membrane with targeted fluorescent probes offers a convenient and non-invasive means to image the cell membrane and follow morphological changes and dynamics in real-time. However, despite many examples of fluorescent plasma membrane probes, a “universal targeting/anchoring moiety” is still required.
