Sulfonyl-Imidazopyridines Decouple Reactivity from Stability for Ligandability Mapping and Covalent Inhibitor Discovery
Covalent probes and therapeutics must balance electrophilicity and stability for function in biological systems, yet gains in stability can sacrifice proteome coverage and limit ligand discovery. Here, we show that single-atom N-to-C substitutions of sulfonyl purines at the nucleofuge position decouple reactivity fro...
