Biological Data

Biological description

XAV 939 is a potent tankyrase (TNKS) inhibitor (IC50 values are 4 and 11 nM at TNKS2 and TNKS1 respectively). Recently it has been indicated that XAV 939 also inhibits multiple PARP family proteins.


XAV 939 antagonizes Wnt signaling by stabilizing axin to stimulate β-catenin degradation.

XAV 939 also displays antiproliferative and apoptotic inducing properties.


XAV 939 robustly induces cardiomyogenesis in mouse embryonic stem (ES) cells.
