InSolution Wnt Antagonist I, IWR-1-endo-CAS 1127442-82-3-Calbiochem

产品说明

一般描述

A cell-permeable p-imidobenzamidoquinoline, endo-diastereomer that is shown to inhibit the activity of TNKS1/PARP5a and TNKS2/PARP5b in in vitro auto-PARsylation assays (IC₅₀ = 131 and 56 nM, respectively) and effectively suppress Wnt-stimulated transcription activity in L-Wnt-STF-based reporter assays (IC₅₀ = 180 nM), while exhibiting little activity against PARP1 or PARP2 (IC₅₀ >18.75 µM). Although both IWR-1-endo and XAV939 (Tankyrase1/2 Inhibitor; >Cat. No. 575545) act as reversible Wnt pathway inhibitors and exhibit similar pharmacological effects both in vitro and in vivo, IWR-1-endo exerts its effect via interaction with Axin, while XAV939 binds TNKS directly.
