Background | Axitinib is a multi-target tyrosine kinase inhibitor that inhibits VEGFR1, VEGFR2, VEGFR3, and PDGFRβ. |
Biological Activity | Axitinib是多靶点的酪氨酸激酶抑制剂,抑制 VEGFR1,VEGFR2,VEGFR3, PDGFRβ 的 IC50 值分别为4,20,4,2 nM[1-3]。 |
IC50 | VEGFR1:0.1nM;VEGFR2:0.2nM;VEGFR3:0.1nM PDGFRβ:1.6nM [1-3] |
In Vitro | Axitinib是VEGFR 1至3的有效选择性抑制剂。在转染或内源性RTK表达细胞中,Axitinib有效阻断生长因子刺激的VEGFR-2和VEGFR-3磷酸化,平均IC50值为0.2和分别为0.1至0.3nM。针对VEGFR-1的细胞活性为1.2nM(在2.3%牛血清白蛋白存在下测量),相当于基于Axitinib的蛋白质结合的~0.1nM的绝对IC 50。在Flk-1转染的NIH-3T3细胞中针对鼠VEGFR-2(Flk-1)的效力为0.18nM,类似于其人同源物的效力。 Axitinib对密切相关的III型和V型RTK显示高出约8至25倍的IC50,包括PDGFR-β(1.6 nM),KIT(1.7 nM)和PDGFR-α(5 nM);纳摩尔浓度的阿西替尼阻断PDGF BB介导的人胶质瘤U87MG细胞(PDGFR-β阳性)迁移但不增殖[2]。 |
In Vivo | 与对照肿瘤相比,单次口服剂量的Axitinib(100mg/kg)显著抑制鼠VEGFR-2磷酸化长达7小时。 Axitinib迅速抑制VEGF诱导的小鼠皮肤血管通透性;抑制作用呈剂量依赖性,与小鼠的药物浓度直接相关。药代动力学/药效学分析表明未结合的EC 50为0.46nM。在没有外源性VEGF-A刺激的MV522荷瘤小鼠的皮肤中也显示出类似的抑制作用。 Axitinib抑制小鼠中人异种移植肿瘤的生长。无论初始肿瘤大小,模型类型或植入部位如何,Axitinib都会产生剂量依赖性生长延迟[2]。 |
Cell Experiment | 在1%FBS(HUVEC)或0.1%FBS(肿瘤细胞)存在下使内皮细胞或肿瘤细胞饥饿18小时。加入Axitinib并将细胞在1mM Na 3 VO 4存在下于37℃温育45分钟。将适当的生长因子加入细胞中,5分钟后,用冷PBS冲洗细胞,并在裂解缓冲液和蛋白酶抑制剂混合物中裂解。将裂解物与免疫沉淀抗体一起在4℃下孵育过夜的蛋白质。将抗体复合物与蛋白A珠缀合,并通过SDS-PAGE分离上清液[2]。 |
Animal Experiment | 小鼠和大鼠[2]给予具有M24met异种移植肿瘤(400-600mm 3)的小鼠单剂量的Axitinib或对照(0.5%羧甲基纤维素/ H 2 O)。收集血液和肿瘤组织样品用于药代动力学和VEGFR-2测量。使用Bradford比色测定法测定肿瘤组织中的总蛋白质浓度。给6日龄Sprague-Dawley大鼠腹膜内注射两次Axitinib(30mg/kg)。处死动物,收集视网膜并裂解,并进行免疫沉淀/免疫印迹实验。 ECL-Plus用于检测,使用Alpha Imager 8800进行光密度分析。 |
