PRI-724, also known as C-82 prodrug/ICG-001 analog, is a potent, specific inhibitor of the canonical Wnt signaling pathway in cancer stem cells with potential antineoplastic activity. Wnt signaling pathway inhibitor PRI-724 specifically inhibits the recruiting of beta-catenin with its coactivator CBP (the binding protein of the cAMP response element-binding protein CREB); together with other transcription factors beta-catenin/CBP binds to WRE (Wnt-responsive element) and activates transcription of a wide range of target genes of Wnt/beta-catenin signaling. Note: Chemical structures of ICG-001 and PRR-724 look very close, but they are not the same molecule. Many vendors confused them.

How to use

In Vitro:

PRI-724 is phosphorylated-C-82 and is rapidly hydrolyzed to its active form C-82 in vivo. PRI-724 treatment reduces the fibrosis induced by CCl4 or BDL. C-82, an active form of PRI-724, inhibits the activation of isolated primary mouse quiescent hepatic stellate cells (HSCs) and promotes cell death in culture-activated HSCs.
