Product Data
Biological target:
K-756 is a direct and selective tankyrase (TNKS) inhibitor, which inhibits the ADP-ribosylation activity of TMS1 amd TMLS2 with IC50s of 31 and 36 nM, respectively.
In vitro activity:
K-756 binds to the induced pocket of TNKS and inhibits its enzyme activity. Moreover, PARP family enzyme assays showed that K-756 is a selective TNKS inhibitor. K-756 inhibited the cell growth of APC-mutant colorectal cancer COLO 320DM and SW403 cells by inhibiting the Wnt/β-catenin pathway.

In vivo activity:
An in vivo study showed that the oral administration of K-756 inhibited the Wnt/β-catenin pathway in colon cancer xenografts in mice. Reference: Mol Cancer Ther. 2016 Jul;15(7):1525-34. https://pubmed.ncbi.nlm.nih.gov/27196752/
