Inhibitor of Wnt processing and secretion. Inactivates PORCN, a membrane-bound O-acyltransferase (MBOAT), and selectively inhibits palmitoylation of Wnt. Blocks Wnt-dependent phosphorylation of Lrp6 receptor and Dvl2, and β-catenin accumulation. Suppresses self-renewal in R1 embryonic stem cells.

I use it as a blocking molecule of the WNT pathway for cardiac differentiation in foreskin fibroblast-derive IPS cells. I obtained succesfully cardiomyocytes in a 5uM concentration.
