Government License Rights This invention was made with government support under Grant No. R01CA201049 awarded by the National Institute of Health (NIH). The government has certain rights in the invention. Background The epidermal growth factor receptor (EGFR, Erb-B1) belongs to a family of receptor tyrosine kinases that mediate the proliferation, differentiation, and survival of normal and malignant cells (Arteaga, C. L., J. Clin. Oncol.19, 2001, 32-40). Deregulation of EGFR has been implicated in many types of human cancer, with overexpression of the receptor present in at least 70% of human cancers (Seymour, L. K., Curr. Drug Targets 2, 2001, 117-133), including non-small lung cell carcinomas, breast cancers, gliomas, squamous cell carcinomas of the head and neck, and prostate cancer (Raymond, E., et al., Drugs 60 (Suppl.1), 2000, 15-23, discussion 41-2; Salomon, D. S., et al., Crit. Rev. Oncol. Hematol.19, 1995, 183-232; Voldborg B. R., et al., Ann. Oncol.8, 1997, 1197-1206). EGFR has, therefore, emerged as an attractive target for the design and development of diagnostic and therapeutic agents that can specifically bind and inhibit the receptor’s tyrosine kinase activity and signal transduction pathway in cancer cells. For example, the EGFR tyrosine kinase (EGFR-TK) reversible inhibitor TARCEVA RTM is approved by the FDA for treatment of NSCLC and advanced pancreatic cancer. Other anti-EGFR targeted molecules have also been approved, including LAPATINIB RTM and IRESSA RTM.

Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are effective clinical therapies for EGFR mutant advanced non-small cell lung cancer (NSCLC) patients (Mok, T. S., et al., N. Engl. J. Med.361, 2009, 947-57; Paez, J. G., et al., Science 304, 2004, 1497-500; Lynch, T. J., et al., N. Engl. J. Med.350, 2004, 2129-39; Rosell, R., et al., Lancet Oncol.13, 2012, 239-46). Several randomized clinical trials have demonstrated that EGFR TKIs are more effective, as measured by response rate (RR) and progression free survival (PFS), than chemotherapy when used as initial systemic treatment for advanced EGFR mutant NSCLC (Mok, T. S., et al., N. Engl. J. Med.361, 2009, 947-57; Rosell, R., et al., Lancet Oncol.13, 2012, 239-46; Sequest, L. V. et al., J. Clin. Oncol.31, 2013, 3327-34; Wu, Y. L., et al., Lancet Oncol.15, 2014, 213-22; Maemondo, M., et al., N. Engl. J. Med.362, 2010, 2380-8; Zhou, C., et al., Lancet Oncol.12, 2011, 735-42; Mitsudomi, T., et al., Lancet Oncol.11, 2010, 121-8). However, the vast majority of patients will develop disease progression following successful treatment with an EGFR TKI. The most common mechanism of acquired resistance, detected in 60% of patients, is a secondary mutation in EGFR at position T790 (T790M) (Yu, H. A., et al., Clin. Cancer Res.19, 2013, 2240-7). This mutation leads to an increase in ATP affinity, thus making it more difficult for reversible EGFR TKIs gefitinib and erlotinib to bind the EGFR TKI domain (Yun C. H., et al., Proc. Natl. Acad. Sci. USA 105, 2008, 2070-5).

Covalent EGFR inhibitors have emerged for inhibiting EGFR T790M-containing cancers. However, in lung cancer patients, afatinib is only effective in EGFR TKI naïve EGFR mutant cancers and has a RR of less than 10% in patients with NSCLC that have developed resistance to gefitinib or erlotinib (Miller, V. A., et al., Lancet Oncol.13, 2012, 528-38). Afatinib is a potent inhibitor of both mutant and wild type (WT) EGFR. Inhibition of WT EGFR leads to toxicities, including skin rash and diarrhea, which limits the ability to escalate afatinib doses in patients to those necessary to inhibit EGFR T790M. Irreversible pyrimidine EGFR inhibitors including the tool compound WZ4002 and clinical compounds CO-1686 and osimertinib, overcome many of the limitations of afatinib (Zhou, W., et al., Nature 462, 2009, 1070-4; Walter, A. O., et al., Cancer Discov.3, 2013, 1404-15; Cross, D. A. E., et al., Cancer Discov. 4, 2014, 1046-61). They are not only more potent on EGFR T790M, but also selectively inhibit mutant over WT EGFR and hence should lead to increased clinical efficacy and less toxicity compared with afatinib (Zhou, W., et al; Walter A. O., et al, Cross, D. A. E., et al.).

However, all current EGFR TKIs target the ATP site, and while third generation irreversible inhibitors can overcome T790M, they are all rendered impotent by the C797S mutation, which is already arising in treated patients. Cetuximab, an anti-EGFR antibody that blocks receptor dimerization, is not effective in EGFR-mutant NSCLC because mutational activation of the kinase is effectively“downstream” of receptor dimerization. Hence, alternative strategies to inhibit EGFR are needed. At present, suitable compounds with alternative mechanisms of action targeting mutant EGFR are not available. Thus, there is a need for novel and potent small molecule EGFR inhibitors with alternative mechanisms of action targeting mutant EGFR. Summary

Example 2: HTRF-based EGFR biochemical assays

EGFR biochemical activity measurements were carried out using the homogeneous time-resolved fluorescence (HTRF) assay (Cisbio). inhibitors and DMSO normalizations were first dispensed to empty black low-volume 384-well plates (Corning) with D300 digital liquid dispenser (HP). All reactions were carried out at room temperature and solutions were added to plates with a Multidrop Combi Reagent Dispenser (ThermoFisher). The reaction mixture (10 mL final volume) contained 1 mM tyrosine kinase peptide-biotin substrate and mutant EGFR in a reaction buffer (50 mM HEPES pH 7.0, 5 mM MgCl ₂ ,1 mM MnCl ₂ , 0.01% BSA, 2 mM TCEP, 0.1 mM NaVO ₄ ). Enzyme concentrations were adjusted to accommodate varying kinase activities (L858R 0.1 nM, L858R/T790M 0.02 nM). Enzyme reaction solution (2x

concentrations, 5 mL) was added to 384-well plates containing compounds and incubated for 30 mins. Enzyme reactions were initiated with the addition of 5 mL of ATP to a final concentration of 100 mM and reacted for 20 mins. Reactions were quenched with the addition of 10 mL of phospho-tyrosine antibody-Europium(III) cryptate (1-to-180 volume ratio) and Streptavidin-XL665 (46.7 nM) in EDTA-containing detection buffer, then incubated at room temperature for 1 hour, and read with a PHERAstar plate reader (excitation = 337 nm, emission = 620 nm and 665 nm). IC ₅₀ values were determined by inhibition curves (11-point curves from 1.0 mM to 0.130 nM or 23-point curves from 1.0 mM to 0.130 pM) in triplicate with non-linear least squares fit in GraphPad Prism 7.0d.

Example 3: Ba/F3 cell proliferation models

The EGFR mutant L858R, Del E746_A750, L858R/T790M, Del E746_A750/T790M, L858R/T790M/C797S, and Del/T790M/C797S Ba/F3 cells have been previously described (Zhou, W., et al. Nature 462, 2009, 1070-1074). All cell lines were maintained in RPMI 1640 (Cellgro; Mediatech Inc., Herndon, CA) supplemented with 10% FBS, 100 units/mL penicillin, 100 units/mL streptomycin. The EGFR I941R mutation was introduced via site directed mutagenesis using the Quick Change Site-Directed Mutagenesis kit (Stratagene; La Jolla, CA) according to the manufacturer's instructions. All constructs were confirmed by DNA

sequencing. The constructs were shuttled into the retroviral vector JP1540 using the Cre- recombination system (Agilent Technologies, Santa Clara, CA). Ba/F3 cells were then infected with retrovirus per standard protocols, as described previously (Zhou, et al, Nature 2009). Stable clones were obtainHG^E\^VHOHFWLRQ^LQ^SXURP\FLQ^^^^^J^PO^^

Growth and inhibition of growth was assessed by the Cell Titer Glo assay (Promega, Madison, WI) and was performed according to the manufacturer’s instructions. The Cell Titer Glo assay is a luminescence-based method used to determine the number of viable cells based on quantitation of the ATP present, which is directly proportional to the amount of metabolically active cells present. Ba/F3 cells of different EGFR genotypes were exposed to compounds as a single agent or in combination with 1Pg/ml cetuximab for 72 hours and the number of cells used per experiment was determined empirically as has been previously established (Zhou, et al., Nature 2009). All experimental points were set up in triplicates in 384-well plates and all experiments were repeated at least three times. The luminescent signal was detected using a spectrometer and the data was graphically displayed using GraphPad Prism version 5.0 for Windows, (GraphPad Software; www.graphpad.com). The curves were fitted using a non-linear regression model with a sigmoidal dose response. Table 4: Inhibition of Proliferation of EGFR L858R/T790M mutant Ba/F3 Cells
