Tankyrase-IN-2 (compound 5k) is a potent, selective, and orally active tankyrase inhibitor (IC50s of 10, 7, and 710 nM for TNKS1, TNKS2 as well as PARP1, respectively). Tankyrase-IN-2 has favorable physicochemical profile and pharmacokinetic properties modulating Wnt pathway activity in a colorectal xenograft model[1].
Tankyrase-IN-2 (1-10000 nM; 24 hours) leads to a dose-dependent increase of tankyrase protein abundance with an EC50 of 320 nM in DLD1 cells. This is in the same potency range as the value for axin2 increase (EC50=319 nM)[1].
