Application

IWP-2 has been used to treat the cell lines L-Wnt-3a and L-Wnt-5a, to demonstrate the inhibitory effect of IWP-2. It has also been used as a Wnt signaling inhibitor to treat WT and Gja1Jrt/+ stromal cells to confirm that, theWnt/β-catenin signaling pathway pathway was not involved in the increased marker expression by Gja1Jrt/+ osteoblasts.

Biochem/physiol Actions

IWP-2 is an inactivator of Porcn function; inhibitor of Wnt production. Wnt/b-catenin (‘canonical′) pathway maintains transcriptional programs that enable stem cells to remain multipotent. Hyperactivation of the Wnt/b-catenin pathway leads to disease stage. IWP-2 inhibits Wnt production. It appears that IWP inactivates Porcn function either by directly inhibiting the Porcn active site or by modulating the function of a Porcn regulator. Porcn is a member of the membrane-bound O-acyltransferase (MBOAT) family, which adds a palmitoyl group to Wnt proteins that is essential to their signaling ability and is required for Wnt secretion. IWP-2 is useful in both regenerative medicine and anticancer efforts.
