Biological Activity

Description WZ4002 is a novel, mutant-selective EGFR inhibitor for EGFR(L858R)/(T790M) with IC50 of 2 nM/8 nM in BaF3 cell line; does not inhibit ERBB2 phosphorylation (T798I).
Targets
EGFR (L858R) [1]
(BaF3 cells)		 EGFR (L858R/T790M) [1]
(BaF3 cells)
2 nM 8 nM
In vitro
In vitro WZ4002 inhibits other EGFR genotypes E746_A750 and E746_A750/T790M with IC50 of 2 and 6 nM. Besides, WZ4002 suppresses widetype ERBB2 with an IC50 of 32 nM. WZ4002 inhibits EGFR, AKT and ERK1/2 phosphorylation in NSCLC cell lines and WZ4002 prevents of EGFR phosphorylation in NIH-3T3 cells expressing different EGFR T790M mutant alleles. For WZ4002, kinases that exhibited greater than 95% inhibition relative to the DMSO control at 10 μM are selected for measurement of their dissociation constants. WZ4002, which possesses an ortho-methoxy group at the C2-aniline substituent, is more selective for EGFR compared to WZ3146. WZ4002 is 100-fold less effective at inhibiting phosphorylation of WT EGFR compared to the quinazoline inhibitors. Similarly, WZ4002 prevents EGFR kinase activity of recombinant L858R/T790M protein more potently than of WT EGFR, while the opposite is observed with HKI-272 and gefitinib. [1] In addition, the phosphorylated EGFR of Src TKI-resistant H1975 cells, as well as HCC827 cells, is completely suppressed by the third generation EGFR TKI, WZ4002. [2]
Kinase Assay EGFR kinase assays
In vitro inhibitory enzyme kinetic assays using recombinant EGFR L858R/T790M and WT protein and are performed using the ATP/NADH coupled assay system in a 96-well format. WZ4002 is added to determine its inhibitory effects.
Cell Research Cell lines NSCLC, Ba/F3 cells, NIH-3T3 cells, PC9GR4 cells
Concentrations 0-1 μM
Incubation Time 72 hours
Method The NSCLC, Ba/F3 cells, NIH-3T3 cells, PC9GR4 cells are used and verified to contain EGFR delE746_A750/T790M by direct sequencing. Cell proliferation and growth assays are performed using the MTS assay. Site directed mutagenesis is performed using the Quick Change Site-Directed Mutagenesis kit.
In Vivo
In vivo In a 2-week efficacy study, WZ4002 treatment results in significant tumor regressions compared to vehicle alone in both T790M containing murine models. [1] Treatment with low-dose WZ4002, and high-dose WZ4002 leads to mean decreases in tracer uptake of 26%, and 36%, respectively. [3]
