产品描述 | WZ4002 is a mutant-selective EGFR inhibitor for EGFR(L858R) and EGFR(T790M) with IC50 of 2 nM/8 nM. |
靶点活性 | EGFR (L858R):2 nM, EGFR (L858R/T790M):8 nM |
体外活性 | 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] |
体内活性 | 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] |
激酶实验 | 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. |
细胞实验 | The NSCLC, Ba/F3 cells, NIH-3T3 cells, PC9 gR4 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.(Only for Reference) |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
