Biological Activity

Potent tankyrase (TNKS) inhibitor (IC50 values are 4 and 11 nM for TNKS2 and TNKS1 respectively). Antagonizes Wnt signaling via stimulation of β-catenin degradation and stabilization of axin. Inhibits proliferation of the β-catenin-dependent colon carcinoma cell line DLD-1. Promotes cardiomyogenic development in mesoderm progenitor cells.
