WIKI4 is a potent tankyrase inhibitor with an IC50 of 26 nM for TNKS2. WIKI4 potently inhibits Wnt/β-catenin signaling and that its half-maximal response dose is 75 nM. WIKI4 mediates its effects on Wnt/β-catenin signaling by inhibiting the enzymatic activity of TNKS2[1][2]. WIKI4 is cytotoxic to SCLC cells with an IC50 value of 0.02 μM[3].
WIKI4 (100 nM, 1 μM; 6 days; DLD1 cells) inhibits growth of DLD1 cells relative to DMSO controls in media containing low serum. WIKI4 inhibits expression of β-catenin target genes and cellular responses to Wnt/β-catenin signaling[1].WIKI4 (1 μM; 2 hours, 4 hours, 6 hours, or 24 hours; DLD1 cells) significantly increases the steady-state abundance of AXIN1 and AXIN2[1].
