What is Wnt-C59?

Description

Wnt-C59 (1243243-89-1) is a potent (IC50 = 74 pmol/L) inhibitor of Porcupine (PORCN), a Wnt-acyltransferase.1 Blockage of Wnt-acyltransferase prevents secretion of all Wnt isoforms.? It was able to block progression of mammary tumors in MMTV-WNT1 transgenic mice.1? Wnt-C59 strongly inhibited the growth of intestinal neoplasia in RZ-mutant mice.2? Wnt-C59 was able to efficiently differentiate pluripotent stem cells into cortical neurons (CTIP2+/COUP-TF1).3? Wnt-C59 was also able to dramatically attenuate kidney fibrosis via inhibition of collagen mRNA expression and expression of inflammatory cytokines.4

The Uses of Wnt-C59

Wnt-C59 is a porcupine homolog – Drosophila (PORCN) inhibitor for Wnt3A-mediated activation of a multimerized TCF-binding site driving luciferase.
