Background:

IC50: 27 nM for Wnt pathway activity

The Wnt signaling pathway is important in embryonic devel_x001F_opment as well as the initiation and progression of a number of types of human cancer. Porcn, a member of the membrane-bound O-acyltransferase (MBOAT) family, adds a palmitoyl group to Wnt proteins that is essential to their signaling ability and is required for Wnt secretion. IWP-2 is a small-molecule antagonist of the Wnt/b-catenin pathway.

In vitro: Expression of Porcn but not Evi alleviated the effects of IWP-2 on pathway activity and Wnt secretion, which suggests that in general IWP-2 may act on Porcn [1].

In vivo: In order to test the in vivo activity of IWP-2, the authors turned to a simple and rapid assay of Wnt/b-catenin pathway activity: regeneration of the zebrafish caudal fin following resection. The addition of IWP-2 to the aquarium water of zebrafish failed to suppress fin regeneration after mechanical resection, which suggests either that IWP-2 have poor bioavailability or that the determinants in the gene product that they target are not conserved in zebrafish [1].

Clinical trial: Up to now, IWP-2 is still in the preclinical development stage.
