OM-153 shows picomolar IC50 inhibition (0.63 nM) in a cellular (HEK293) WNT/β-catenin signaling reporter assay, no off-target liabilities, overall favorable absorption, distribution, metabolism, and excretion (ADME) properties, and an improved pharmacokinetic profile in mice.
OM-153 decreases cell growth in COLO 320DM cells with a GI50 value of 10 nM and a GI25 value of 2.5 nM (concentrations resulting in 50% and 25% growth inhibition, respectively), while cell growth in RKO cells was insubstantially affected by the treatment.
OM-153 inhibits WNT/β-catenin, YAP, and MYC signaling and shows an antiproliferative fffect in human cancer cell lines.
