Application

4,6-Dimethyl-2-(methylsulfinyl)-3-nitropyridine is a sulfoxide-containing fragment for covalent ligand discovery via cysteine labeling as demonstrated by Zamboldo and coworkers. Fragment electrophiles are useful in chemoproteomic and ligandability studies for both traditionally druggable proteins as well as ″undruggable,″ or difficult-to-target, proteins.

Related useful products may include cysteine fragment KB02 (912131), IA alkyne (924237), IA 5-TAMRA (925020), desthiobiotin iodoacetamide (923826), or biotin iodoacetamide (B2059).

The emerging use of covalent ligands as chemical probes and drugs would benefit from an expanded repertoire of cysteine-reactive electrophiles for efficient and diverse targeting of the proteome. Here we use the endogenous electrophile sensor of mammalian cells, the KEAP1-NRF2
