After starved in serum-free medium for 24h,A549 cells incubated with the indicated concentrations of WZ8040 for 3h,followed by 20-minute stimolation of 100ng/ml EGF.
Dr. Zhang of Tianjin Medical University. WZ8040 purchased from Selleck.
For MTT assays, cells (2,000 ~ 5,000 cells/well) were subcultured into 96-well plates according to their growth properties. Cell proliferation was assayed at 72 hr after treatment of WZ8040 by adding 20 μl of 5 mg/ml 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) solution per 100 μl of growth medium. After incubating for 3-4 h at 37°C, the media were removed and 150 µl/well of MTT solvent (either absolute DMSO or isopropanol containing 4 μM HCl and 0.1% Nonidet-40) was added to dissolve the formazan.

|Description||WZ8040 is a novel mutant-selective irreversible EGFRT790M inhibitor, does not inhibit ERBB2 phosphorylation (T798I).|
|Features||Inhibits EGFR T790M mutation and not wild-type EGFR.|
WZ8040 is 30- to 100-fold more potent against EGFR T790M, and up to 100-fold less potent against wild-type EGFR, than quinazoline-based EGFR inhibitors such as CL-387785 and HKI-272. WZ8040 treatment potently inhibits the growth of HCC827 (EGFR Del E746_A750), PC9 (EGFR Del E746_A750), H3255 (EGFR L858R), H1975 (EGFR L858R/T790M), and PC9 GR (EGFR Del E746_A750/T790M) with IC50 of 1 nM, 6 nM, 66 nM, 9 nM, and 8 nM, respectively. WZ8040 weakly inhibits the growth of HCC827 GR (EGFR E746_A750/MET amp), H1819 (ERBB2 amp), Calu-3 (ERBB2 amp), H1781 (ERBB2 Ins G776V, C), and HN11 (EGFR & ERBB2 WT) with IC50 of >3.3 μM, 738 nM, 915 nM, 744 nM, and 1.82 μM, respectively. WZ8040 is not toxic up to 10 μM against A549 (KRAS mutant) or H3122 (EML4-ALK) cells.

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
