General description

A cell-permeable benzothiazolyl-acetamide compound that inhibits the cellular Wnt processing and secretion via selective blockage of MBOAT (membrane-bound O-acyltranferase) family member Porcn- (Porcupine) mediated Wnt palmitoylation. IWP-2 does not affect Wnt/β-catenin signaling pathway in general and, unlike IWR-1-endo (Cat. No. 681669), displays no effect against Wnt-stimulated cellular responses.

Packaging
