(2-Nonen-1-yl)succinic anhydride (CAS 28928-97-4)

(2-Nonen-1-yl)succinic anhydride, commonly referred to as NSAn, is a chemical compound widely utilized in research settings for its unique properties in modifying biomolecules. Primarily, NSAn acts as a reactive electrophile, facilitating covalent modifications on nucleophiles such as thiols present in proteins. This reactivity has been extensively harnessed to explain protein-protein interactions, as NSAn enables the specific labeling of cysteine residues within target proteins, aiding in the characterization of protein structure and function. Furthermore, NSAn has been instrumental in the development of novel chemical biology tools, including activity-based protein profiling (ABPP) assays, which enable the identification and quantification of enzyme activities within complex biological systems. Recent research has also demonstrated the utility of NSAn derivatives in the selective labeling of cellular proteins, offering insights into dynamic protein-protein interactions and post-translational modifications. Additionally, NSAn-based chemical probes have been employed in the investigation of intracellular signaling pathways, particularly those involving redox regulation, by facilitating the visualization and manipulation of target proteins within living cells. The versatility of NSAn as a chemical tool extends beyond protein labeling, with applications in the modification of nucleic acids and small molecules, further expanding its utility in biochemical research. Overall, (2-Nonen-1-yl)succinic anhydride represents a valuable asset in the arsenal of chemical biology techniques, enabling precise manipulation and interrogation of biological systems at the molecular level.
