Catalog Number: 3748
Chemical Name: 3,5,7,8-Tetrahydro-2-[4-(trifluoromethyl)phenyl]-4H-thiopyrano[4,3-d]pyrimidin-4-one
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.
