EGFRmutant- in-1, A 5-methylpyrimidopyridone derivative are effective selective EGFRL858R T790M C797S mutantinhibitors with IC50 of 27.5 nM, which significantly weakened EGFRWT effect.
EGFR-IN-1, an orally active and irreversible selective inhibitor targeting L858R T790M mutantEGFR, exhibits strong antiproliferative and antitumor activity, particularly against H1975 cells and first line mutant HCC827 cells. This compound potently inhibits Gefitinib-resistant EGFR L858R T790M mutations with a 100-fold selectivity over the wild-type EGFR.
EGFR ligand-2 (compound C4) is a covalent EGFR ligand and mutantinhibitor with IC50 values of 21 nM for EGFR L858R and 48 nM for EGFR L858R T790M. It can be utilized in the synthesis of PROTAC [1].
