| 名稱 | Pilaralisib |
| 描述 | Pilaralisib (XL-147) is an orally available small molecule that selectively inhibits the activity of phosphoinositide-3 kinase (PI3K). Pilaralisib has been used in trials studying the treatment of Cancer, Lymphoma, Solid Tumors, Glioblastoma, and Breast Cancer, among others. |
| 細(xì)胞實驗 | Cell proliferation is measured by using MTT or pre-mixed WST-1 reagent. For MTT/WST-1 assays, 10,000 cells/well are seeded in 96-well plates. 24 h after plating, cells are treated with DMSO or pilaralisib. After 5 days of treatment, MTT/WST-1 assays are performed.(Only for Reference) |
| 激酶實驗 | In vitro kinase inhibition assays: Kinase activity for PI3K isoforms is measured as the percentage of ATP consumed following the kinase reaction using luciferase–luciferin-coupled chemiluminescence, with ATP concentrations approximately equal to the Km for each respective kinase. Kinase reactions are initiated by combining test compounds, ATP and kinase in a 20 μL volume. PI3Kα, PI3Kβ, PI3Kγ, and PI3Kδ final enzyme concentrations are 0.5, 8, 20, and 2 nM, respectively. Of note, 0.5 μL dimethyl sulfoxide (DMSO) containing varying concentrations of the test compound is mixed with 10 μL enzyme solution (2×concentration). Kinase reactions are initiated by the addition of 10 μL of liver phosphatidylinositol and ATP solution (2×concentration). Assay concentrations for VPS34, ATP, and phosphatidylinositol are 40 nM, 1 μM, and 5 μM, respectively |
| 體外活性 | Pilaralisib 在小兒臨床前測試計劃 (PPTP) 細(xì)胞系展示出細(xì)胞毒活性，中位相對IC50值為10.9 mM（范圍從2.7 mM到24.5 mM）。[2] |
| 體內(nèi)活性 | 在 BALB/c nu/nu 小鼠中，Pilaralisib（100 mg/kg，p.o.）能有效抑制實體膠質(zhì)瘤異種移植物的生長。Pilaralisib 的耐受性良好，治療組的毒性率僅為0.7%。[2] 在無胸腺雌性小鼠中，Pilaralisib（100 mg/kg，p.o.）顯著延緩腫瘤生長，且未觀察到顯著的藥物相關(guān)毒性。[3] |
