SGI-1776 free base是一种有效的ATP竞争性Pim激酶抑制剂。Pim激酶属于丝氨酸/苏氨酸激酶家族,调节细胞存活。生物医学鉴定表明SGI-1776对Pim家族的三个亚型具有特异性,包括Pim-1、Pim-2和Pim-3。在前列腺癌细胞中,SGI-1776剂量依赖性地减少参与细胞周期进程和凋亡(p21Cip1/WAF1和Bad)的Pim激酶底物的磷酸化;通过诱导G1细胞周期停滞损害整体细胞活力,触发凋亡;降低基于多药耐药蛋白1(MDR1)的紫杉醇难治的前列腺癌细胞的细胞活力。

运输条件 | 蓝冰运输或根据您的需求运输。 |
一般建议 | 不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
细胞实验[1]: | |
细胞系 |
CLL患者中分离的原代淋巴细胞 |
溶解方法 |
在DMSO中的溶解度>10 mM。为了获得更高的浓度,可以将离心管在37℃加热10分钟和/或在超声波浴中震荡一段时间。原液可以在-20℃以下储存几个月。 |
反应条件 |
10 μM;24小时 |
应用 |
原代CLL细胞与1、3和10 μM的SGI-1776孵育24小时导致细胞凋亡的增加,与未处理细胞相比,分别增加了10%、22%和38%。CLL细胞与SGI-1776孵育48或72小时进一步增加凋亡细胞的百分比。 |
动物实验[2]: | |
动物模型 |
786-O或Caki-1异种移植雌性BALB/c裸鼠 |
剂量 |
200 mg/kg,一次/5天,3周;口服给药 |
应用 |
与对照组相比,在两个异种移植模型中,SGI-1776显著减少平均肿瘤体积。除此之外,SGI-1776诱导Bad磷酸化的减少,而不改变总Bad蛋白的水平。SGI-1776也可以诱导适度的细胞凋亡。 |
注意事项 |
请测试所有化合物在室内的溶解度,实际溶解度和理论值可能略有不同。这是由实验系统的误差引起的,属于正常现象。 |
