ProtocolIn VitroEAI045 potently inhibits EGFR Y1173 phosphorylation in H1975 cells (EC50=2 nM), but not in HaCaT cells. EAI045 is an inhibitor of the L858R/T790M mutant with 1000-fold selectivity versus wild type EGFR at 1 mM ATP. Profiling of EAI045 against a panel of 250 protein kinases reveals exquisite selectivity; no other kinases are inhibited by more than 20% at 1 μM EAI045.
In VivoIn a genetically engineered mouse model of L858R/T790Mmutant-driven lung cancer , remarkable tumor regression is observed in L858R/T790M-mutant mice treated with the combination of EAI045 and cetuximab. No response is seen in those mice treated with EAI045 alone. The same effect is seen in both L858R/T790M/C797S- engineered Ba/F3 cells and in mice carrying the L858R/T790M/C797S tumor xenografts. These assays clearly show that EAI045 can overcome resistance from acquired T790M and C797S mutations.
These protocols are for reference only. InvivoChem does not independently validate these methods.
