| Name | WHI-P154 |
| Description | WHI-P154 (Jak3 inhibitor ii) is a potent JAK3 inhibitor. |
| Cell Research | 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.(Only for Reference) |
| Kinase Assay | 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. |
| In vitro | The in vitro anti-glioblastoma activity of WHI-P154 was amplified > 200-fold and was selective by binding to recombinant human-derived epidermal growth factor. WHI-P154 inhibited STAT1 activation, iNOS expression and NO production in macrophages in vitro. WHI-P154 was shown to inhibit other common kinases, including EGFR, Src, Abl, VEGFR, MAPK and PI3-K, and induced apoptosis in human glioblastoma cell lines.WHI-P154 inhibited the adhesion and migration of glioblastoma cells in the ECM. WHI-P154 was significantly cytotoxic to human malignant glioma cell lines U373 and U87, causing apoptotic cell death at micromolar concentrations. |
