XAV939 is a potent and selective Wnt pathway antagonist. It functions to stabilize Axin by inhibiting tankyrase 1 and tankyrase 2 (IC50 = 11 nM and 4 nM, respectively). It has been used to study Wnt-dependent cancers. In addition, XAV939 has been shown to induce cardiomyocyte differentiation from mouse and human ESCs/iPSCs.
