β-catenin

SKL2001 is an agonist of the Wnt/β-catenin pathway, with anti-cancer activity. SKL2001 stabilizes intracellular β-catenin via disruption of the Axin/β-catenin interaction.

FzM1.8 is an allosteric agonist of the Frizzled receptor FZD4 with pEC50 of 6.4. FzM1.8 binds to FZD4 and activates the WNT/β-catenin pathway, by promoting TCF/LEF transcriptional activity in the absence of any WNT ligand. FzM1.8 binding stabilizes FZD4 with an increased affinity for heterotrimeric G protein and stimulates the release of the Gβγ subunit that in turn activates PI3K.
