Background | PF-562271 is a potent, reversible, ATP-competitive FAK and Pyk2 kinase inhibitor. |
Biological Activity | PF-562271 是有效,可逆,ATP竞争性的 FAK 和 Pyk2 激酶抑制剂,IC50 分别为 1.5 和 13 nM。[1-3] |
IC50 | 1.5nM(FAK),13nM(Pyk2),30nM(CDK2),47nM(CDK3),58nM(CDK1),97nM(CDK7),97nM(Flt3)[1-3] |
In Vitro | PF-562271是FAK和PYK2的选择性抑制剂。使用PF-562271在一系列浓度下处理7个细胞系5天。用PF-562271处理在所有细胞系中都具有细胞活力,处理3天后平均IC50为2.4μM。 TC32和A673是2种最敏感的细胞系,IC50浓度分别为2.1和1.7μM[2]。PF-562271在重组酶测定中显示为CDK2/E,CDK5/p35,CDK1/B和CDK3/E的30-120nM抑制剂,在基于细胞的测定中评估CDK的作用,48 - 需要小时暴露3.3μMPF-562271以改变细胞周期进程。 PF-562271在诱导型细胞分析中有效,可测量磷酸化FAK,IC50为5 nM [1]。 |
In Vivo | 在给予荷瘤小鼠后,PF-562271以剂量依赖性方式抑制体内FAK磷酸化(EC50为93ng/mL)[1]。接受PF-562271的大鼠在治疗2周后显示肿瘤生长减少,骨质愈合的迹象表明,新骨(皮质和松质骨)在先前被肿瘤损伤的部位沉积[3]。 |
Cell Experiment | 将尤文肉瘤细胞置于10-cm培养皿中,使其粘附24小时,然后用PF-562271,PD0325901或达沙替尼处理。 |
Animal Experiment | 小鼠[1]无胸腺雌性小鼠(CD-1 Nu/Nu,~20克)用于所有体内研究。将指数生长的细胞用胰蛋白酶消化并重悬于无菌PBS中,并将sc(每只小鼠1×10 6个细胞,200μL)接种到小鼠的右侧腹中。将携带150mm 3大小肿瘤的动物分成接受载体(5%Gelucire)或PF-562,271(在载体中稀释)的组,并通过灌胃给药。每2天获得动物体重和肿瘤测量值。用游标卡尺测量肿瘤体积(mm 3)并使用下式计算:长度(mm)×宽度(mm)×宽度(mm)×0.5。生长抑制百分比。对于所有肿瘤生长抑制实验,使用每剂量组8至10只小鼠。 使用大鼠[3] Nude(Crl:NIH-rnu)雌性大鼠。 PF-562271配制用于使用0.5%甲基纤维素进行口服给药。在给药的第一天,大鼠通过口服强饲法接受单剂量的PF-562271(10mg/kg)。基于给药后1小时的暴露水平,剂量降至5mg/kg。从第二天开始,通过口服强饲法每天给大鼠施用5mg/kg,持续28天。在肿瘤接种后2周开始给药,并且仅在通过放射线照相确认肿瘤存在之后开始给药。在研究过程中确认了测试化合物在血清中的存在。 |
Kinase Experiment | 纯化活化的FAK激酶结构域(氨基酸410-689)与50μMATP和10μg/孔的Glu和Tyr,p(Glu/Tyr)的随机肽聚合物在激酶缓冲液(50mM HEPES pH)中反应7.5,125mM NaCl和48mM MgCl 2)15分钟。用浓度为1μM的浓度为1/2-Log的连续稀释的化合物攻击p(Glu/Tyr)的磷酸化。每种浓度一式三份进行测试。用普通的抗磷酸酪氨酸(PY20)抗体,然后用辣根过氧化物酶(HRP)缀合的山羊抗小鼠IgG抗体检测p(Glu/Tyr)的磷酸化。加入HRP底物,加入终止溶液(2M H 2 SO 4)后得到450nm处的吸光度读数。 |
