MTI-31 potently inhibited cell proliferation (IC50 <1 μmol/L) and in vivo tumor growth in multiple NSCLC models of EGFR/T790M, EML4-ALK, c-Met, or KRAS (MED <10 mg/kg)....We first assessed antiproliferative activity of MTI-31 in a panel of six NSCLC cell lines, which included representative lines with oncogenic EGFR (HCC827, PC9, and H1975), c-Met (H1993), EML4-ALK (H2228), or KRAS (A549)...
