DA-0157 is the orally active inhibitor for EGFR and ALK that overcomes drug-resistant mutations of EGFR C797S and ALK in NSCLC) cells. DA-0157 inhibits the proliferation of Ba/F3-EGFR Del19/T790M/C797S (IC50 = 6.9 nM), Ba/F3-EGFR WT (IC50 = 0.83 µM), Ba/F3-EML4-ALK-L1196M (IC50 = 5.5 nM), and Ba/F3-EML4-ALK (IC50 = 7.4 nM). DA-0157 inhibits CYP2D6 with IC50 of 5.26 µM. DA-0157 exhibits antitumor efficacy in mouse models[1].
