IWP-2 (686770-61-6) is an inhibitor of Wnt secretion and processing. It blocks Wnt-dependent signaling (IC50= 27 nM) by inhibition of the O-acyltransferase Porcn1. Induces cardiomyocyte differentiation from human pluripotent stem cells2. IWP-2 is an important tool to probe the involvement of the Wnt pathway in physiological processes3,4. Cell permeable.
