Sulfonyl fluorides are becoming increasingly popular in covalent probe discovery and are often used as tool compounds in chemical biology. Their high stability and low reactivity made them promising in modern drug discovery. Sulfonyl fluorides are known to react with multiple nucleophilic amino acid residues including Tyr, Lys, His, Arg, Ser and Thr. That is especially important due to the much higher abundance of Ser and Lys in proteins over Cys (on average about 9% and 6% vs 2%).

There is a significant difference in reactivity between fluoro sulfonates, sulfamoyl fluorides, and alkyl aryl/hetaryl sulfonyl fluorides, which enables the design of selective covalent binders. For example, less reactive fluoro sulfonates have been reported to react better with Tyr phenolic hydroxy groups than sulfonyl fluorides and sulfamoyl fluorides.

A recently published study by the research group at GSK on hydrolytic stability and reactivity of various sulfonyl fluorides, reveals interesting findings and a way to profile sulfonyl fluorides. Several substituted benzene sulfonyl fluoride scaffolds have been reported to possess balanced reactivity due to enough stability to hydrolysis and moderate activity toward nucleophiles.
