IWP-2 is a potent and highly selective Wnt signaling antagonist with an IC50 ~ 27 nM in the L-Wnt-STF cellular assay. It prevents palmitoylation of Wnt proteins by Porcupine (a membrane-bound O-acyltransferase), thereby blocking Wnt protein secretion and activity. It blocks Wnt-dependent phosphorylation of Lrp6 receptor and Dvl2, and β-catenin accumulation. IWP-2 is a useful chemical probe in both regenerative medicine and anticancer efforts.
