產品描述: XL147 analogue is a selective and reversible class I PI3K inhibitor for PI3Kα/δ/γ. |
靶點:
Apoptosis;DNA-PK;PI3K;PI3K |
體內研究:
XL147濃度為20 μM時誘導細胞死亡。用XL147處理導致PI3K的劑量依賴性抑制。抑制細胞凋亡的同時,XL147誘導細胞周期蛋白D1和pRB的減少和CDK抑制劑p27KIPI水平的增加,但是在總的或切割的多聚(ADP-核糖)聚合酶(PARP)上水平沒有可檢測到的變化。用XL147處理,導致pAKTS473/T308和pS6S240/244的劑量依賴性減少。XL147是選擇性的可逆PI3K抑制劑,作用于p110α時IC50為40 nM。XL147抑制PI3K亞型,是ATP競爭性抑制劑。在一組HER2過表達人乳腺癌細胞系中,用XL147處理消除AKT和S6磷酸化,但也誘導HER??3和其他RTK的表達和磷酸化。在HER2 +細胞中,用siRNA抑制HER3或用HER2抑制劑曲妥珠單抗或拉帕替尼共處理可增強XL147誘導的細胞死亡和對pAKT和pS6的抑制作用 |
細胞實驗:
Cells including BT474, HCC1937 et al. are seeded in 100-mm dishes in media containing 2.5% FBS with or without XL147. After 3 days, detached and adherent cells are pooled, xed, and labeled with propidium iodide by using the APO-BrdU kit. Labeled cells are analyzed using the Becton Dickinson FACSCalibur system.
