G007-LK is a potent and specific inhibitor of tankyrase 1/2 with IC50 values of 46 and 25 nM [1].

The telomeric repeat factor 1 (TRF1)-interacting ankyrin-related ADP-ribose polymerase 1 (tankyrase 1,TNKS1) and tankyrase 2 (TNKS2) belong to the subgroup of poly(ADP-ribosyl)ating polymerases and regulate the assembly and disassembly of large polymerized structures [1].

G007-LK is a potent and specific tankyrase 1/2 inhibitor. G007-LK reduced auto-poly-(ADP ribosy)lation of TNKS1 and TNKS2 with IC50 values of 46 nM and 25 nM, respectively. In Wnt3a-induced HEK 293 cells, G007-LK inhibited ST-Luc with IC50 value of 0.05 μM [1]. In SW480 colorectal cancer cell line transfected with GFP-TNKS1, G007-LK induces highly dynamic and mobile degradasomes containing phosphorylated beta-catenin, beta-TrCP and ubiquitin [2]. In the APC-mutant cell lines, G007-LK reduces cytosolic and nuclear β-catenin protein levels [3].

In mice bearing COLO-320DM cell xenografts, G007-LK (20 mg/kg twice daily or 40 mg/kg daily) concentration-dependently inhibited tumor growth by 61% and 48%, respectively. Also, G007-LK reduced the levels of TNKS1/2 and β-catenin, and stabilized AXIN1/2 [3].
