IWR-1-endo is a small molecule inhibitor of Wnt Response with IC50 value of 180nM [1].
IWR-1-endo is a small molecule antagonists of the Wnt/β-catenin pathway screened out from a diverse synthetic chemical library. It acts as an inhibitor of Wnt response. IWR-1-endo can inhibit the activity of Wnt1, 2 and 3. In cultured cells, IWR-1-endo inhibits Wnt-induced β-catenin accumulation which is a downstream event of Lrp6 and Dvl2. It is proved that IWR-1-endo promote β-catenin destruction through promoting stability of Axin-scaffolded destruction complexes in the DLD-1 colorectal cancer (CRC) cell line. IWR-1-endo is also shown to inhibit tailfin regeneration and epithelial stem cell self-renewal in zebrafish. These two processes are both dependent on Wnt/β-catenin signaling. Furthermore, IWR-1-endo can block aberrant cell growth supported by hyperactivation of Wnt/β-catenin resulting from Apc loss [1].

Other notes
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
