Background

G007-LK is a potent and specific inhibitor of tankyrase 1/2 with IC50 values of 46 and 25 nM [1].

The telomeric repeat factor 1 (TRF1)-interacting ankyrin-related ADP-ribose polymerase 1 (tankyrase 1,TNKS1) and tankyrase 2 (TNKS2) belong to the subgroup of poly(ADP-ribosyl)ating polymerases and regulate the assembly and disassembly of large polymerized structures [1].

G007-LK is a potent and specific tankyrase 1/2 inhibitor. G007-LK reduced auto-poly-(ADP ribosy)lation of TNKS1 and TNKS2 with IC50 values of 46 nM and 25 nM, respectively. In Wnt3a-induced HEK 293 cells, G007-LK inhibited ST-Luc with IC50 value of 0.05 μM [1]. In SW480 colorectal cancer cell line transfected with GFP-TNKS1, G007-LK induces highly dynamic and mobile degradasomes containing phosphorylated beta-catenin, beta-TrCP and ubiquitin [2]. In the APC-mutant cell lines, G007-LK reduces cytosolic and nuclear β-catenin protein levels [3].

In mice bearing COLO-320DM cell xenografts, G007-LK (20 mg/kg twice daily or 40 mg/kg daily) concentration-dependently inhibited tumor growth by 61% and 48%, respectively. Also, G007-LK reduced the levels of TNKS1/2 and β-catenin, and stabilized AXIN1/2 [3].

一般建议为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。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。

试验操作

细胞实验[1]:

细胞系

COLO-320DM细胞系

溶解方法

在DMSO中的溶解度> 26.5mg/mL。为了获得更高浓度,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

0.2 μmol/L,7-13天

应用

G007-LK抑制细胞周期进程,降低集落形成并诱导分化,表明细胞b-catenin依赖的未分化状态的维持可能被tankyrase酶的抑制而阻断。

动物实验[1]:

动物模型

异种移植COLO-320DM肿瘤小鼠

剂量

20,40,60 mg/kg,腹腔注射,每天一次持续21天

应用

G007-LK对异种移植COLO-320DM肿瘤小鼠具有抗肿瘤功效。在这些小鼠中,TNKS1和TNKS2蛋白水平降低,AXIN1和AXIN2稳定,b-catenin水平降低。

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。
