NVP-TNKS656 is a highly potent, selective and oral bioavailable tankyrase inhibitor with IC50 of 6 nM for TNKS2. It has 300-fold selectivity against PARP1 and PARP2. In MMTV-Wnt1 tumor models, NVP-TNKS656 was dosed to mice orally to stabilize Axin1 protein and reduce the Wnt/beta-catenin target gene Axin2 mRNA level by 70-80%. In colorectal cancer PDX models, NVP-TNKS656 reduces nuclear β-catenin, reverts such resistance, and represses tumor growth.

How to use
NVP-TNKS656 was used at 10 µM in vitro and cellular assays.
In MMTV-Wnt1 tumor bearing athymic nude mice, NVP-TNKS656 was dosed to mice orally at 100-350 mg/Kg once per day to stabilize Axin1 protein and reduce the Wnt/beta-catenin target gene Axin2 mRNA level by 70-80%. In colorectal cancer PDX models, NVP-TNKS656 reduces nuclear β-catenin, reverts such resistance, and represses tumor growth.
