Wnt生成抑制剂,IWP-3 is a selective small molecule wnt inhibitor, prevents palmitylation of Wnt proteins by Porcupine (Porcn), a membrane-bound O-acyltransferase, thereby blocking Wnt secretion and activity1.
IWP-3 is an potent inhibitor of Wnt production with an IC50 of 40 nM. IWP-3 inhibits Porcupine (Porcn) function thereby blocking palmitoylation of Wnt proteins. IWP-3 inhibits CK1γ3 and CK1ε only moderately and does not inhibit CK1α.
