XAV-939是tankyrase 1/2的小分子抑制剂,IC50值分别为11和4 nM[1]。
XAV-939是作为Wnt/β-catenin途径的抑制剂而被筛选到的。在HEK293细胞中,XAV-939显著抑制Wnt3a刺激的STF活性和β-catenin积累。在SW480细胞中,XAV-939也抑制STF的活性,增加β-catenin的磷酸化。据报道,XAV-939通过抑制tankyrases,从而稳定Axin的水平,进而抑制Wnt信号。XAV-939与tankyrase 1和tankyrase 2的催化结构域紧密结合,Ki值分别为99和93 nM。此外,XAV-939显著抑制β-catenin依赖的DLD-1细胞,而非β-catenin不依赖的RKO细胞的集落形成[1]。

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 |
HCT116 细胞 |
溶解方法 |
该化合物在DMSO中的溶解度大于10 mM。若配制更高浓度的溶液,一般步骤如下:请将试管置于37℃加热10分钟和/或将其置于超声波浴中震荡一段时间。原液于-20℃可放置数月。 |
反应条件 |
20 μM,24小时 |
实验结果 |
使用XAV-939处理HCT116细胞,然后用PI染色并进行流式细胞术分析或裂解进行免疫印迹分析。结果显示,阻滞在G1期的细胞数为71.01%,而未处理对照组样品为45.54%。蛋白质印迹分析结果显示,XAV-939增加AXIN的水平并抑制β-连环蛋白的表达。 |
动物实验[2]: | |
动物模型 |
小鼠 |
剂量 |
腹膜内注射, 2.5 mg/kg, 每天四次 |
实验结果 |
与假处理的bleomycin攻击小鼠相比,使用XAV-939治疗bleomycin攻击的小鼠减少50%的真皮增厚。在用XAV-939处理的小鼠中,肌成纤维细胞的数量和羟脯氨酸含量也显著降低。 |
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。 |
