Assay: EGFR Exon 19 Deletion and Exon 20 T790M Concurrent Mutations: A compound's ability in selectively inhibiting EGFR exon 19 deletion and T790M concurrent mutations can be assessed using Ba/F3 cells, a murine pro-B cell line, which have been transduced with EGFR exon 19 deletion and T790M mutation. An expression vector, pLVX-IRES puro (Clontech) coding for human EGFR E746-A750 deletion and T790M Mutation, was transfected into HEK293 cells by the Trans-Lentiviral ORF Packaging System (Thermo Scientific), to produce virus encoding EGFR exon 19 deletion and T790M mutations. Ba/F3 (DSMZ) cells maintained in RPMI 1640 medium supplemented with 10% fetal bovine serum, 200 μM L-glutamine/200 μg/mL penicillin/200 μg/mL streptomycin (Life Technology) and 10 ng/mL IL-3 (R&D system), were infected by EGFR E746-A750 deletion and T790M Mutation virus and subsequently selected by puromycin (Life Technology) selection and IL-3 depletion. Ba/F3 cells expressing EGFR E746-A750 deletion and T790M Mutation (named Ba/F3-EGFR-Del/T790M) can proliferate in the absence of IL-3. The anti-proliferative activity of compounds was determined as follows: BaF3-EGFR-Del/T790M cells seeded in 96 well plates (2500 cells/well) were treated with test compound (dissolved in DMSO) at a series of concentrations (4-fold dilution, top concentration: 10,000 nM). The plates were incubated for 72 h in a 37° C. incubator with 5% CO2, and the number of viable cells in each well were measured indirectly by CellTiter 96® Aqueous One Solution Cell Proliferation Assay (Promega; this assay is a colorimetric method for determining the number of viable cells through measurement of their metabolic activity by detection of enzymatic conversion of tetrazolium salts into blue formazan derivatives). Reagent (20 μL) was added into each well, and the plates were returned to the incubator for 2 h. The absorbance in each well was then measured at 490 nm using an Envision plate reader (Perkin Elmer). IC50 values were calculated by determining the concentration of compound required to decrease the MTS signal by 50% comparing to the DMSO control in best-fit curves using Microsoft XLfit software or Accelrys Pipeline Pilot.

Assay: EGFR Exon 21 L858R and Exon 20 T790M Concurrent Mutations: A compound's ability in selectively inhibiting EGFR L858R and T790M concurrent mutations can be assessed using Ba/F3 cells, a murine pro-B cell line, which have been transduced with EGFR L858R and T790M double mutations. An expression vector, pLVX-IRES puro (Clontech) coding for human EGFR L858R and T790M double mutation, was transfected into HEK293 cells by the Trans-Lentiviral ORF Packaging System (Thermo Scientific), to produce virus encoding EGFR L858R and T790M double mutations. Ba/F3 (DSMZ) cells maintained in RPMI 1640 medium supplemented with 10% fetal bovine serum, 200 μM L-glutamine/200 μg/mL penicillin/200 μg/mL streptomycin (Life Technology) and 10 ng/mL IL-3 (R&D system), were infected by EGFR L858R and T790M double mutation virus and subsequently selected by puromycin (Life Technology) selection and IL-3 depletion. Ba/F3 cells expressing EGFR L858R and T790M double mutation (named Ba/F3-EGFR L858R/T790M) can proliferate in the absence of IL-3. The anti-proliferative activity of compounds was determined as follows: BaF3-EGFR L858R/T790M cells seeded in 96 well plates (2500 cells/well) were treated with test compound (dissolved in DMSO) at a series of concentrations (4-fold dilution, top concentration: 10,000 nM). The plates were incubated for 72 h in a 37° C. incubator with 5% CO2, and the number of viable cells in each well were measured indirectly by CellTiter 96® Aqueous One Solution Cell Proliferation Assay (Promega; this assay is a colorimetric method for determining the number of viable cells through measurement of their metabolic activity by detection of enzymatic conversion of tetrazolium salts into blue formazan derivatives). Reagent (20 μL) was added into each well, and the plates were returned to the incubator for 2 h. The absorbance in each well was then measured at 490 nm using an Envision plate reader (Perkin Elmer). IC50 values were calculated by determining the concentration of compound required to decrease the MTS signal by 50% comparing to the DMSO control in best-fit curves using Microsoft XLfit software or Accelrys Pipeline Pilot.
