Wnt-β-Catenin Signaling Inhibitor, FzM1

A cell-permeable, biarylurea derivative that acts as a reversible inhibitor of Wnt-b-catenin signaling (EC50 = 5.74 µM). Acts by blocking the phosphorylation and nuclear translocation of beta-catenin thereby reduces the transcription of TCF/LEF-regulatory genes. Also shown to block TCF/LEF activation induced by lithium chloride. However, it does not affect GSK3-β or the APC destruction complex. Induces con-formational changes in Fz4-WT that ultimately allow it to inhibit β-catenin nuclear transport. Shown to promote HA-Fz4-FEVR plasma membrane localization in U87MG glioblastoma cells and Caco-2 cells (~ 10 µM). Also reported to abolish Norrin-dependent TCF/LEF activation and gene transcription in HEK293 cells.
