Description: XAV-939 is a Tankyrase (TNKS) inhibitor with potential anticancer activity. XAV-939 antagonizes Wnt signaling via stimulation of β-catenin degradation and stabilization of axin. XAV-939 inhibits proliferation of the μ-catenin-dependent colon carcinoma cell line DLD-1. Promotes cardiomyogenic development in mesoderm progenitor cells.
