<p>Allosteric kinase inhibitors represent a promising new therapeutic strategy for targeting kinases harboring oncogenic driver mutations in cancers. Here, we report the discovery, optimization, and structural characterization of allosteric mutant-selective EGFR inhibitors comprising a 5,10-dihydro-11-dibenzo[,][1,4]diazepin-11-one scaffold. Our structure-based medicinal chemistry effort yielded an inhibitor () of the EGFR(L858R/T790M) and EGFR(L858R/T790M/C797S) mutants with an IC of ∼10 nM and high selectivity, as assessed by kinome profiling. Further efforts to develop allosteric dibenzodiazepinone inhibitors may serve as the basis for new therapeutic options for targeting drug-resistant EGFR mutations.</p>
