  • Western blot analysis confirm suppression of the biomarker p-EGFR upon treatment with EGFR TKIs in U-CH1 and UM-Chor1. Cells were serum-starved overnight before they were treated with a range of concentrations of the EGFR inhibitors for 4 h and then EGF-spiked (50 ng/ml) for 15 min. Endogenous controls (non-serum-starved, non-EGF-spiked), untreated controls (serum-starved, non-EGF-spiked) and vehicle controls (serum-starved, treated with 2.5% DMSO, EGF-spiked) were included. Phospho-EGFR was measured by western blot.

AZD8931 shows different potency to NSCLC and SCCHN cell lines. AZD8931 has high sensitivity to PC-9 cells (EGFR activating mutation) with GI50 of 0.1 nM and low activity to NCI-1437 cells with GI50 above 10 μM. AZD8931 exhibits more potency against phospho-EGFR, phospho-erbB2 and phospho-erbB3 than either lapatinib or gefitinib in PE/CA-PJ41, PE/CA-PJ49, DOK and FaDu cells. [1]

In vivo AZD8931 reveals antitumor activity in BT474c, Calu-3, LoVo, FaDu and PC-9 xenografts. AZD8931 could reduce p-Akt, Ki67 expression and p-ERK in BT474c xenografts following acute treatment. AZD8931 also causes induction of the M30 apoptosis marker. Furthermore, AZD8931 shows greater proapoptotic effect compared with gefitinib and lapatinib in LoVo xenografts. [1]

Protocol

Kinase Assay:

+ Expand

Isolated kinase assays:

The intracellular kinase domains of human EGFR and erbB2 are cloned and expressed in the baculovirus/Sf21 system. The inhibitory activity of AZD8931 is determined with ATP at Km concentrations (0.4 mM for erbB2 and 2 mM for EGFR) using the ELISA method.

  • Concentrations: 0.001-10 μM
  • Incubation Time: 96 hours
  • Method:

    To determine the antiproliferative activity against cell lines grown in vitro, AZD8931 is tested in a panel of NSCLC and SCCHN cell lines. Cells are incubated for 96 hours with AZD8931 (0.001-10 μM). Viable cell number is determined by 4 hours of incubation with MTS Colorimetric Assay reagent and absorbance measured at 490 nm on a spectrophotometer.
