Biological Activity
JW 55 is a potent and selective β-catenin signaling pathway inhibitor, which functions via inhibition of the PARP domain of tankyrase 1 and tankyrase 2 (TNKS1/2). JW 55 decreases auto-PARsylation of TNKS1/2 in vitro with IC50s of 1.9 μM and 830 nM respectively.
In Vitro
JW 55 (JW55) is a potent and selective inhibitor of the canonical Wnt pathway. Wnt3a-induced HEK293 cells containing a transiently transfected ST-Luc (SuperTop-luciferase) reporter show inhibition by JW55 with an IC50 value of 470 nM. JW55 is effective in the range of 1 to 5 μM in SW480 cells and 0.01 to 5 μM in HCT-15 cells. JW55 is effective in the range of 1 to 5 μM in SW480 cells and 0.01 to 5 μM in HCT-15 cells[1].
In Vivo
JW 55 (100 mg/kg, orally) reduces tumor development in conditional Apc knockout mice. JW55 reduces XWnt8-induced axis duplication inXenopus embryos and Tamoxifen-induced polyposis formation in conditional APC mutant mice[1].
