Biological Activity

Description IWP-2 is an inhibitor of Wnt processing and secretion with IC50 of 27 nM in a cell-free assay, selective blockage of Porcn-mediated Wnt palmitoylation, does not affect Wnt/β-catenin in general and displays no effect against Wnt-stimulated cellular responses. IWP-2 specifically inhibits CK1δ.
Targets
Wnt [1]
(Cell-free assay)		 M82FCK1δ [3]
(Cell-free assay)
27 nM 40 nM
In vitro

IWP-2 is useful in both regenerative medicine and anticancer efforts. IWP-2 inactivates Porcn, a membrane-bound O-acyltransferase (MBOAT), and selectively inhibits palmitoylation of Wnt. IWP-2 blocks Wnt-dependent phosphorylation of Lrp6 receptor and Dvl2, and β-catenin accumulation. [1]
Features Selective inhibitor of Porcn-mediated Wnt secretion.
