Biological Activity

IWP 2 is a potent inhibitor of Wnt processing and secretion (IC50 = 27nM). IWP 2 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. IWP 2 suppresses self-renewal in R1 embryonic stem cells and promotes cardiomyocyte differentiation from hPSCs. The compound has also been used in protocols to reprogram human somatic cells to chemically-induced PSCs.

Wnt pathway inhibitor that works really well
By Anonymous on 12/09/2019
Species: Human

I used it as a Wnt pathway inhibitor in Hepatocellular Carcinoma Cells. I used the concentration 5uM and it works really well.
