Application

4-(2-(Hex-5-ynamido)ethyl)benzenesulfonyl fluoride is an alkyne-functionalized sulfonyl fluoride activity-based probe (SFABP). Sulfonyl fluorides covalently modify reactive serines in addition to threonine, lysine, tyrosine, cysteine, and histidine residues in a context-specific manner. Activity-based probes are useful for the targeting, isolation, and identification of proteins. Furtermore, the alkyne handle on SFABP enables click chemistry-based incorpoation of azide tags, such as fluorophores or biotins, for visualization or enrichment and detection, respectively.

Sulfonyl fluoride electrophiles have found significant utility as reactive probes in chemical biology and molecular pharmacology. As warheads they possess the right balance of biocompatibility (including aqueous stability) and protein reactivity. Their functionality is privileged in this regard as they

The elucidation of protein/drug interactions remains a major challenge in drug discovery. Liquid chromatography-tandem mass spectrometry has emerged as a tremendously powerful technology for this endeavor, but its full potential has yet to be realized owing in part to unresolved

Chemical probes have great potential for identifying functional residues in proteins in crude proteomes. Here we studied labeling sites of chemical probes based on sulfonyl fluorides (SFs) on plant and animal proteomes. Besides serine proteases and many other proteins, SF-based
