Sulfonyl-triazole compounds and related sulfonyl-heterocycle compounds are described. The compounds can be used to identify reactive nucleophilic amino acid residues, such as reactive tyrosines and reactive lysines, in proteins and to modify the activity of proteins with reactive nuclophilic amino acid residues via the formation of protein adducts comprising a fragment of the compounds. Methods are also described for screening the compounds to identify ligands of proteins comprising a reactive lysine or a reactive tyrosine.

LG for activating nucleophilic substitution reactions on tyrosine sites of proteins. Here, we probed tunability of SuTEx for fragment-based liganddiscovery by modifying the adduct group (AG) and LG with functional groups of differing electron-donating and -withdrawing properties. We discovered the sulfur electrophile is highly sensitive to the position of modification (AG versus LG), which enabled both
