  • The protein expressions of p-Stat3/Stat3, Wnt 3a, Notch 1, and the activation of the Wnt and Notch pathways (Cyclin D1 and Hes 1) were assessed by Western blotting and RT-PCR. The Western blotting results were normalized to β-actin or Histone 4 as the control. Cells were pretreated with WHI-P154 (2 μM) 2 h before adding IL-23 (50 ng/mL). IL-23 treatment (50 ng/mL, 24 h) activated Wnt/Notch signaling and the persistent phosphorylation level of Stat3 was maintained up to 24 h in TE-1 cells (left panel). Relative mRNA level of Cyclin D1 and Hes 1 were detected by RT-PCR in TE-1 cells (right panel). Compiled data were produced from three independent experiments. **p < 0.01.

    (B) Ovaries at 16.5 dpc were cultured with WHI-P154 (15 μM) in vitro. After 3 days of culture, phospho-STAT3 and total STAT3 expression levels in WHI-P154, or control-treated ovaries were analyzed by western blot. β-ACTIN served as a loading control (n=10). (D) After 7 days of culture, WHI-P154-treated ovarian sections were immunolabeled with MVH (green) and the pregranulosa cell marker FOXL2 (red). Scale bar: 50 μm.

  • Reversal effect of WHI-P154 on the sensitivity of NCI-H460/MX20 cells to mitoxantrone. The figure showes the survival curves of cells at different concentrations of mitoxantrone with or without WHI-P154. Cell viability was determined by MTT Assay. NCI-H460 is lung cancer cell line while NCI-H460/MX20 is ABCG2 overexpressing drug (mitoxantrone) selected cell line.

WHI-P154 is first described as a JAK3 inhibitor that displays no activity at JAK1 or JAK2. WHI-P154 inhibits STAT1 activation, iNOS expression and NO production in macrophages in vitro. But it is proved that WHI-P154 also inhibits other common kinases including EGFR, Src, Abl, VEGFR, MAPK and PI3-K and induces apoptosis in human glioblastoma cell lines. [1] WHI-P154 inhibits glioblastoma cell adhesion and migration in the context of ECM.[2] WHI-P154 exhibits significant cytotoxicity against U373 and U87 human glioblastoma cell lines, causing apoptotic cell death at micromolar concentrations. The in vitro antiglioblastoma activity of WHI-P154 is amplified > 200-fold and rendered selective by conjugation to recombinant human epidermal growth factor (EGF). In vitro treatment with EGF-P154 results killing of glioblastoma cells at nanomolar concentrations with an IC50 of 813 nM, whereas no cytotoxicity against EGF-R-negative leukemia cellsis observed, even at concentrations as high as 100 mM.[3]

体内試験 The in vivo administration of EGF-P154 results in delayed tumor progression and improved tumor-free survival in a severe combined immunodeficient mouse glioblastoma xenograft model. Whereas none of the control mice remain alive tumor-free beyond 33 days (median tumor-free survival, 19 days) and all control mice have tumors that rapidly progress to reach an average size of > 500 mm3 by 58 days, 40% of mice treated for 10 consecutive days with 1 mg/kg/day EGF-P154 remain alive and free of detectable tumors for more than 58 days with a median tumor-free survival of 40 days. The tumors developing in the remaining 60% of the mice never reache a size > 50 mm3.[3]

Kinase assays:

WHI-P154 is tested in kinase assays. The panel of kinases is selected to broadly cover the kinome, providing a good approximation of specificity. For all kinases, recombinant rat (IKKβ) or human (all others), full-length or GST-kinase domain fusion proteins, are used. WHI-P154 is inactive (concentration that inhibits response by 50% [IC50] > 30 μM) for the following kinases: AKT, AuroraA, cdk2, cdk6, CHK1, FGFR1, GSK3b, IKKb, IKKi, INSR, MAPK1, MAPKAP-K2, MASK, MET, PAK4, PDK1, PKCb, ROCK1, TaoK3, TrkA.

  • 実験の流れ: Cells are seeded into a 96-well plate at a density of 2.5×104 cells/well and incubated for 36 h at 37 ℃ before drug exposure. On the day of treatment, culture medium is carefully aspirated from the wells and replaced with fresh medium containing the quinazoline compounds WHI-P154 at concentrations ranging from 0.1 μM to 250 μM. Triplicate wells are used for each treatment. The cells are incubated with the compound for 24hours to 36hours at 37 ℃ in a humidified 5% CO2 atmosphere. To each well, 10 μL of MTT (final concentration, 0.5 mg/mL) is added, and the plate are incubated at 37 ℃ for 4 h. Than solubilized overnight at 37 ℃ in a solution containing 10% SDS in 0.01 M HCL. The absorbance of each well is measured in a microplate reader at 570 nm.
