  • Antitum o r activity of WZ4002 and/or E7050 in mouse xenograft models of human tumors. SCID mice-bearing PC-9/Vec (A), PC-9/HGF#5 (B), H1975 (C), or HCC827ER (D) tumors were administered 25 mg/kg WZ4002 and/or E7050 once daily for 14 to 21 days. Tumor volume was measured using calipers on the indicated days. Mean?SE tumor volumes are shown for groups of 4 to 5 mice.

  • (a) Western blots examine the effects of WZ4002 alone or a combination of WZ4002 and ABT-263 in H1975 parental or SR cells in suspension. Cells were grown for 48 h and then treated with the indicated pharmacological agent(s) for another 24 h. The cleaved/total poly (ADP-ribose) polymerase-1 (PARP-1) ratio determined for each cell line using Image J software is also represented. The values are the means of three independent experiments. (b) Quantification of apoptotic cells assessed by PARP-1 cleavage from each cell line.

    Caspase 3/7 activation in H1975 SR cells and HCC827 cells. Cells were seeded and left in suspension for 24 h, and then untreated or treated with the indicated drug(s) for another 24 h before being assessed. Caspase activity was evaluated by using the Caspase-Glo 3/7 assay and normalized to a 1.0 arbitrary unit for the mean of three untreated wells.

  • 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 WZ4002 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 mM HCl and 0.1% Nonidet-40) was added to dissolve the formazan.

製品説明 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).

2 nM 8 nM

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]

体内試験 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]
