Molecular Weight 409.44 CAS No. 1127442-82-3
Solubility (25°C)* In vitro DMSO 21 mg/mL (51.28 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
1.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 30 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description IWR-1-endo (endo-IWR 1, IWR-1) is a Wnt pathway inhibitor with IC50 of 180 nM in L-cells expressing Wnt3A, induces Axin2 protein levels and promotes β-catenin phosphorylation by stabilizing Axin-scaffolded destruction complexes.
Targets
Wnt [1]
(L-cells expressing Wnt3A)
180 nM
In vitro

Although both IWR-1 and XAV939 act as reversible Wnt pathway inhibitors and exhibit similar pharmacological effects both in vitro and in vivo, IWR-1 exerts its effect via interaction with Axin, while XAV939 binds TNKS directly. [1]
In vivo

IWR-1 is a β‐catenin inhibitor.[3]

Protocol (from reference)

Cell Assay:

[2]
  • Cell lines

    Pig EpiSCs

  • Concentrations

    2.5 μM

  • Incubation Time

    2 days

  • Method

    For neural induction, the 3i/LAF culture medium was replaced with neural induction medium I (2.5 μM IWR-1-endo, 5 μM SB431542, and 10 ng/mL FGF2 in BM) on day 2 after pgEpiSC passage.
