Tankyrase1/2 Inhibitor IV, JW55

A cell-permeable phenylcarbamoylfuran-carboxamide compound that acts as a potent, selective, and reversible inhibitor of poly(ADP-ribosyl)ation activity of tankyrase 1 and 2 (IC₅₀ = 1.9 and 0.83 µM, respectively). Exhibits high selectivity over PARP1 (IC₅₀ = 20 µM). Stabilizes and increases AXIN2 levels, thereby enhancing phosphorylation and degradation of β-catenin resulting in reduced canonical Wnt signaling (IC₅₀ = 470 nM in Wnt 3a-induced HEK293 cells transfected with ST-Luc). Shown to induce cell cycle arrest and diminish the proliferation of SW480 colorectal cancer cells (~ 5 µM). Suppresses tumor growth in tamoxifen-induced polyposis in Apc knock-out murine model (100 mg/kg, i.p.). Displays adequate human liver microsomal stability (t_1/2 = 10.1 min).
