- 產(chǎn)品描述: PF-8380是一種有效的自毒素 (ATX)抑制劑,在體外酶活性實驗中測得IC50為2.8 nM
- 靶點: Autotaxin(Cell-free assay):2.8 nM;PDE
- 體外研究:
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。
- 體內研究:
在放射輻射前進行PF-8380的預處理可抑制輻射誘導的腫瘤血管內皮細胞的血管生成、在體內延遲神經(jīng)膠質瘤腫瘤生長與發(fā)展。 在大鼠氣囊炎模型中,口服30 mg/kg的PF8380可減少炎性痛覺過敏,3小時內,在血漿和炎癥組織位置造成大于95%的LPA水平降低
- 細胞實驗: Cell lines: 小鼠GL261和人U87-MG細胞 Concentrations: 1 μM Incubation Time: 45 min Method: 在細胞培養(yǎng)板中培養(yǎng)GL261或U87-MG細胞,使其達到70%融合率。用無菌的200 μL槍頭將半融合細胞層(semi-confluent cell layer)輕輕刮下,以形成一層無細胞層。用PBS清洗一遍平板,以移除非黏連細胞和細胞碎片。對于放射線增減藥物研究,細胞在輻射實驗前用1 μM PF-8380或DMSO處理45分鐘,然后置于37℃,5% CO2中培養(yǎng)。對照板用于觀測其細胞遷移(20-24h)。細胞用70%乙醇固定,用1%亞甲藍染色。為了計算其遷移,在刮層區(qū)域選擇任意三個HPFs進行統(tǒng)計
- 動物實驗: Animal Models: Male Lewis rats Dosages: 1, 3, 10, 30, and 100 mg/kg Administration: 口服
