Covalent small molecule drugs have emerged as a crucial support in precision therapy due to their high selectivity and robust potency. DNA-encoded chemical library (CoDEL) technology is an advanced platform for covalent drug discovery. However, the application of CoDELs constrained by single-residue focus limited warhead diversity. Here we report method identify residue-selective inhibitors using with diverse warheads targeting multiple distinct residues. We systematically evaluated reactivity 17 9 nucleophilic amino acids FGFR2 then constructed comprising 24.8 million compounds. These enabled identification active cysteine, lysine, arginine, or glutamic acid. The lysine-targeting inhibitor engaged novel reactive site. arginine-targeting demonstrated subtype overcame resistance. acid-targeting validated druggability this unconventional residue findings suggest that our work could potentially expand target space promote harnessing power CoDELs.
