IWP-4(CAT: I011135) is a potent and selective inhibitor of porcupine (PORCN), a membrane-bound O-acyltransferase essential for the palmitoylation and activation of Wnt proteins. By inhibiting PORCN, IWP-4 effectively blocks Wnt secretion and signaling, making it a valuable tool in stem cell and cancer research. Its mechanism allows researchers to study Wnt-driven processes, including embryonic development, tissue regeneration, and tumor progression. IWP-4 is particularly useful in investigating the role of Wnt signaling in diseases such as cancer, fibrosis, and degenerative disorders, providing insights into therapeutic strategies targeting the Wnt pathway.
