Application

IWR-1 has been used as an antagonist for Wingless/Integrated (WNT) signaling pathway in human embryonic stem cells (hESCs), mice lewis lung carcinoma (LLC) and Sepia embryos.

Biochem/physiol Actions

IWR-1 is a tankyrase inhibitor and is cytotoxic for cancer stem-like cells. It inhibits the in vivo progression of osteosarcoma. IWR-1 interacts with RNA polymerase II and is crucial for the formation of preinitiation complex.

The Wnt/b-catenin (‘canonical’) pathway maintains transcriptional programs that enable stem cells to remain multipotent. Hyperactivation of the Wnt/b-catenin pathway leads to disease stage. IWR-3 act as inhibitors of Wnt response. It appear that IWR compounds induce stabilization of Axin proteins via a direct interaction, which is a part of the b-catenin destruction complex (consists of Apc, Axin, Ck1 and Gsk3b).
