Mechanism of Action

Features	Selective inhibitor of Porcn-mediated Wnt secretion.
Targets/IC₅₀/Ki	Wnt (Cell-free assay) 27 nM ^M82FCK1δ (Cell-free assay) 40 nM
In vitro	IWP-2 is useful in both regenerative medicine and anticancer efforts. This compound inactivates Porcn, a membrane-bound O-acyltransferase (MBOAT), and selectively inhibits palmitoylation of Wnt. It blocks Wnt-dependent phosphorylation of Lrp6 receptor and Dvl2, and β-catenin accumulation.
