- 产品描述: PF-8380是一种有效的自毒素 (ATX)抑制剂,在体外酶活性实验中测得IC50为2.8 nM
- 靶点: Autotaxin(Cell-free assay):2.8 nM;PDE
- 体外研究:
PF-8380 also inhibits rat autotaxin with an IC50 of 1.16 nM with FS-3 substrate. Potency of PF-8380 is maintained when using enzyme produced from fetal fibroblasts used in combination with lysophosphatidyl choline (LPC) as a substrate. In human whole blood incubated with PF-8380 for 2 h, autotaxin is inhibited with an IC50 of 101 nM[1]. Autotaxin (ATX), an enzyme with lysophospholipase D (lysoPLD) activity, catalyzes the production of lysophosphatidic acid (LPA) from lysophosphatidylcholine (LPC). Pre-treatment of GL261 and U87-MG cells with 1 μM PF-8380 followed by 4 Gy irradiation results in decreased clonogenic survival, decreases migration (33% in GL261; P=0.002 and 17.9% in U87-MG; P=0.012), decreases invasion (35.6% in GL261; P=0.0037 and 31.8% in U87-MG; P=0.002), and attenuates radiation-induced Akt phosphorylation。
- 体内研究:
在放射辐射前进行PF-8380的预处理可抑制辐射诱导的肿瘤血管内皮细胞的血管生成、在体内延迟神经胶质瘤肿瘤生长与发展。 在大鼠气囊炎模型中,口服30 mg/kg的PF8380可减少炎性痛觉过敏,3小时内,在血浆和炎症组织位置造成大于95%的LPA水平降低
- 细胞实验: Cell lines: 小鼠GL261和人U87-MG细胞 Concentrations: 1 μM Incubation Time: 45 min Method: 在细胞培养板中培养GL261或U87-MG细胞,使其达到70%融合率。用无菌的200 μL枪头将半融合细胞层(semi-confluent cell layer)轻轻刮下,以形成一层无细胞层。用PBS清洗一遍平板,以移除非黏连细胞和细胞碎片。对于放射线增减药物研究,细胞在辐射实验前用1 μM PF-8380或DMSO处理45分钟,然后置于37℃,5% CO2中培养。对照板用于观测其细胞迁移(20-24h)。细胞用70%乙醇固定,用1%亚甲蓝染色。为了计算其迁移,在刮层区域选择任意三个HPFs进行统计
- 动物实验: Animal Models: Male Lewis rats Dosages: 1, 3, 10, 30, and 100 mg/kg Administration: 口服
