EGFR-IN-1, an orally active and irreversible selective inhibitor targeting L858R T790M mutant EGFR, exhibits strong antiproliferative and antitumor activity, particularly against H1975 cells and first line mutant HCC827 cells. This compound potently inhibits Gefitinib-resistant EGFRL858R T790M mutations with a 100-fold selectivity over the wild-type EGFR.
EGFR mutant- in-1, A 5-methylpyrimidopyridone derivative are effective selective EGFRL858R T790M C797S mutant inhibitors with IC50 of 27.5 nM, which significantly weakened EGFRWT effect.
Mutated EGFR-IN-3 is a ATP-competitive and highly selective allosteric dibenzodiazepinone EGFR(L858R T790M) and EGFR(L858R T790M C797S) inhibitor(IC50 of 12 nM and 13 nM, respectively. )
