EGFR-IN-1 TFA (compound 24) is an orally active and irreversible L858R/T790M mutant selective EGFR inhibitor. EGFR-IN-1 TFA potently inhibits Gefitinib-resistant EGFR L858R, T790M with 100-fold selectivity over wild-type EGFR. EGFR-IN-1 TFA displays strong antiproliferative activity against the H1975 cells and the first line mutant HCC827 cells. Antitumor activity. has not independently confirmed the accuracy of these methods. They are for reference only.
EGFR-IN-1 TFA (30 mg/kg; p.o.; daily for 2 weeks) displays significant tumor growth inhibition with no observed loss in body weight.
EGFR-IN-1 TFA evaluates in a time course PD experiment upon oral dosing at 30 mg/kg. EGFR-IN-1 TFA shows a >50% inhibition of phosphorylation of EGFR for >12 h. EGFR-IN-1 TFA reaches maximal concentration of 0.10 μM at 2 h and systemic exposure (AUC0-inf.) is 0.33 μM. h. has not independently confirmed the accuracy of these methods.
