PF-06459988 is an orally activity, irreversible and mutant-selective inhibitor of EGFR mutant forms. PF-06459988 demonstrates high potency and specificity to the T790M-containing double mutant EGFRs. PF-06459988 can be used for the research of cancer In Vitro PF-06459988 (0-10 μM; 2 h) shows good cellular potency to NSCLC cell lines and high selectivity between the potent target and WT EGFR. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Cytotoxicity AssayCell Line: NSCLC cell lines Concentration: 0-10 μM Incubation Time: 2 hours Result: Exibited excellent cellular potency to H1975 (L858R/T790M), PC9-DRH (Del/T790M), H3255 (L858R), PC9 (Del), HCC827 (Del) and A549 (WT) cell lines with IC 50 values of 13, 7, 21, 140, 90 and 5100 nM, respectively. Showed high specificity to T790M-containing double mutan EGFRs. Form:Solid IC50& Target:IC50: 45 nM (H1975 EGFR), 3.3 μM (EGFR)
