ChEMBL	Cell Proliferation Inhibition Assay: The following in vitro assay is to determine the activity of the tested compounds for inhibiting the proliferation of cancer cells, which has high expression of EGFR. The activity is represented by the IC50 value. The general procedures of the assay are given as follows: The cancer cells A431 that highly expressing EGFR (Institute of biochemistry and cell biology) were chosen and seeded to 96-well cell culture plate at a suitable concentration (e.g., 5000 cells/mL medium). The cells then were incubated in carbon dioxide (CO2) incubator until they reached 85% confluency. Then, the cell culture medium was replaced by fresh one with tested compounds added in it at serial concentrations (general 6 to 7 concentrations). Then the cells were put back to the incubator and cultured continuously. 72 hours later, the activity of the tested compounds for inhibiting the cell proliferation was determined by using Sulforhodamine B (SRB) method.

ChEMBL	Time-Resolved Fluorescence Assay: The following assay may be used to determine the activity of the compounds of the invention for inhibiting EGFR kinase activity. The half maximal inhibitory concentration IC50 (the concentration of the tested compound showing 50% inhibition of the enzyme activity) of each compound was determined by incubating several different concentrations of the tested compounds with a specific enzyme and substrate. EGFR kinase used in this assay is a human-derived recombinant protein (Cell signaling technology, #7908), which was reacted with peptide substrate and different concentrations of tested compounds in a buffer solution containing 60 mM HEPES (pH7.5), 5 mM MgCl2, 5 mM MnCl2, 3 μM Na3VO4, 1.25 M DTT (1000×) and 20 μM ATP at 25° C., for 45 minutes. The EGFR kinase activity was determined by using a Time-Resolved fluorescence method.	B	7.89	pIC50	13	nM	IC50	US-9358227-B2.
