IWP-2 is an inhibitor of Wnt processing and secretion with IC50 of 27 nM in a cell-free assay, selective blockage of Porcn-mediated Wnt palmitoylation, does not affect Wnt/β-catenin in general and displays no effect against Wnt-stimulated cellular responses.

KIF3A knockdown promotes both ligand secretion and intracellular signalling of the Wnt/β-catenin pathway in NSCLC cell lines. (c,d) SuperTOPFlash reporter assay to examine the effect of KIF3A knockdown on signalling pathway activation by autocrine or exogenous WNTs in A549 and SW900 cell lines. A549 and SW900 cells were incubated with DMSO or IWP-2 (30 μ M) for 48 h, and then treated with BSA or WNT3A (100 ng/ml) for additional 24 h. Luciferase reporter activity was calculated by dividing TOP/RL ratio by FOP/RL ratio (n = 3; error bars indicate SEM; p-value was determined by one-way ANOVA). *P < 0.05; **P < 0.01.

(b-d) Combined and temporal treatment with IWP-2, SAG and FGF8 resulted in robust induction of MGE cells from H9 and H7 hESCs as well as iPSCs, assayed after 25 days of differentiation. The image in the insets is Hoechst-labeled nuclei of the same microscope field. Scale bar: 100 μm.

|Description||IWP-2 is an inhibitor of Wnt processing and secretion with IC50 of 27 nM in a cell-free assay, selective blockage of Porcn-mediated Wnt palmitoylation, does not affect Wnt/β-catenin in general and displays no effect against Wnt-stimulated cellular responses.|
|Features||Selective inhibitor of Porcn-mediated Wnt secretion.|
IWP-2 is useful in both regenerative medicine and anticancer efforts. IWP-2 inactivates Porcn, a membrane-bound O-acyltransferase (MBOAT), and selectively inhibits palmitoylation of Wnt. IWP-2 blocks Wnt-dependent phosphorylation of Lrp6 receptor and Dvl2, and β-catenin accumulation.

* 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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
