- 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(shí)驗(yàn)中測(cè)得IC50為2.8 nM
- 靶點(diǎn): 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(nèi)研究:
在放射輻射前進(jìn)行PF-8380的預(yù)處理可抑制輻射誘導(dǎo)的腫瘤血管內(nèi)皮細(xì)胞的血管生成、在體內(nèi)延遲神經(jīng)膠質(zhì)瘤腫瘤生長(zhǎng)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(jué)過(guò)敏,3小時(shí)內(nèi),在血漿和炎癥組織位置造成大于95%的LPA水平降低
- 細(xì)胞實(shí)驗(yàn): Cell lines: 小鼠GL261和人U87-MG細(xì)胞 Concentrations: 1 μM Incubation Time: 45 min Method: 在細(xì)胞培養(yǎng)板中培養(yǎng)GL261或U87-MG細(xì)胞,使其達(dá)到70%融合率。用無(wú)菌的200 μL槍頭將半融合細(xì)胞層(semi-confluent cell layer)輕輕刮下,以形成一層無(wú)細(xì)胞層。用PBS清洗一遍平板,以移除非黏連細(xì)胞和細(xì)胞碎片。對(duì)于放射線(xiàn)增減藥物研究,細(xì)胞在輻射實(shí)驗(yàn)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(duì)照板用于觀測(cè)其細(xì)胞遷移(20-24h)。細(xì)胞用70%乙醇固定,用1%亞甲藍(lán)染色。為了計(jì)算其遷移,在刮層區(qū)域選擇任意三個(gè)HPFs進(jìn)行統(tǒng)計(jì)
