Biological Activity:

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.

 

How to Use:

 

  • In vitro: IWP-2 was used at 1-2 µM in vitro and in cellular assays.
  • In vivo: n/a
