β-catenin inhibitor C2 is a novel potent selective β-catenin inhibitor with Kd of 54.96 nM, directly to ARM domain of β-catenin.β-catenin inhibitor C2 reduced viability of DLD1 and SW480 cells in dose-dependent manner with IC50 ranging between 0.8-1.3 uM, viability of HCT116 and SW48 with IC50 3.45-5.35 uM.β-catenin inhibitor C2 selectively inhibits β-catenin, lowers its cellular load and significantly reduces viability of β-catenin-driven cancer cells.

iCRT-3 is a selective, cell-permeable β-catenin responsive transcription (CRT) inhibitor with IC50 of 8.2 nM.

IMU1003 (IMU-1003) is a small molecule inhibitor of Wnt/β-catenin signaling, decreases β-catenin levels and inhibits target gene expression that promotes cancer cell proliferation.
