苦鬼臼毒素生物活性

[ 描述 ]:

Picropodophyllin (AXL1717) 是选择性的胰岛素样生长因子-1受体 (IGF-1R)抑制剂,IC50 为1 nM。

信号通路 >> 蛋白酪氨酸激酶 >> IGF-1R

研究领域 >> 癌症

[ 靶点 ]

IC50: 1 nM (IGF-1R)

[体外研究]

鬼臼苦素(AXL1717)(0.5,2.5,10μM)有效抑制完整细胞中IGF-1刺激的IGF-1R,Akt(Ser 473)和Erk1/2磷酸化。鬼臼苦素(AXL1717)也抑制细胞生长,并诱导培养的IGF-1R阳性肿瘤细胞凋亡[1]。鬼臼苦素(AXL1717)通过进一步降低细胞活力和增强细胞凋亡,协同增敏HMCL,原代人MM和鼠5T33MM细胞对ABT-737和ABT-199的作用[3]。鬼臼苦素和索拉非尼协同抑制肝细胞癌细胞的增殖和运动[4]。

[体内研究]

鬼臼苦素(AXL1717)(20mg/kg/12h,ip)在用人ES-1,BE和PC3异种移植的SCID小鼠中引起完全肿瘤消退[1]。鬼臼苦素(AXL1717)显示出有效的抗肿瘤活性,可提高5T33MM小鼠模型的存活率[2]。

[动物实验]

使用4至5周龄的无病原体SCID小鼠并将其容纳在无菌设施中的塑料隔离器内。 ES-1，BE和PC3细胞（均被证实表达IGF-1R）或Rv-src（IGF-1R阴性）和P12（过表达IGF-1和IGF-1R）以107细胞/小鼠皮下注射在0.2mL体积的无菌盐水溶液中。免疫活性Balb-c小鼠每只小鼠在0.15mL体积的无菌盐水溶液中注射107JC鼠乳腺癌细胞。用鬼臼苦素（AXL1717）（20mg / kg / 12h）进行的实验处理通过每天腹膜内注射10μL体积的DMSO：植物油，10：1（v / v）中的化合物来进行。对照小鼠仅用载体处理。每组治疗三只动物。使用游标卡尺每隔一天测量肿瘤生长，并计算肿瘤体积。仔细观察小鼠是否存在副作用，并在实验结束时将其处死以进行病变的组织学分析。对鬼臼苦素（AXL1717）处理（系统和局部）无肿瘤小鼠的单独实验，包括各种器官的组织学分析，证实了先前观察到鬼臼苦素（AXL1717）似乎是无毒的。
