XAV-939通过抑制tankyrase1/2而选择性抑制Wnt/β-catenin介导的转录,IC50为11 nM/4 nM,调节轴蛋白水平,但对CRE, NF-κB和TGF-β无作用。A potent inhibitor of beta-catenin, TNKS1, and TNKS2.
Information
XAV-939 XAV-939 (NVP-XAV939) selectively inhibits Wnt/β-catenin -mediated transcription through tankyrase1/2 inhibition with IC50 of 11 nM/4 nM in cell-free assays, regulates axin levels and does not affect CRE, NF-κB or TGF-β.
In vitro
XAV-939 specifically inhibits tankyrase PARP activity. XAV-939 dramatically decreases DNA-PKcs protein levels, confirming the critical role of tankyrase poly-ADP-ribosylation activity in maintaining stability of the DNA-PKcs protein. The greatest reduction of DNA-PKcs protein levels (< 25% relative expression compared to DMSO treated controls) occurs at 12 hours with 1.0 μM XAV-939 exposure. Treatment of human lymphoblasts with 1.0 μM XAV-939 results in marked elevation of tankyrase 1 levels. XAV-939 is axin stabilizing agent. XAV-939 stimulates beta-catenin degradation by stabilizing axin, the concentration-limiting component of the destruction complex. XAV-939 stabilizes axin by blocking the poly-ADP-ribosylating enzymes tankyrase 1 and tankyrase 2. Both tankyrase isoforms interact with a highly conserved domain of axin and stimulate its degradation through the ubiquitin-proteasome pathway. XAV-939 deregulates the Wnt/b-catenin pathway which has been implicated in many cancers.
