Biological Activity for IWP 2

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.

IWP2 for small molecule pathway.
By Anonymous on 07/23/2021
Assay Type: In Vitro
Species: Human

IWP2 was used for cardiomyocyte differentiation of pluripotent stem cells. IWP2 was used at a concentration of 5 uM on day 3 of the differentiation schedule. The image shows differentiated cardiomyocytes.
