Background

XAV939 (CAS 284028-89-3) is a cell-permeable small molecule inhibitor, functioning as an inhibitor of tankyrase enzymes, particularly targeting TNKS1 and TNKS2, and exhibiting potent inhibitory activity in cellular models involving Wnt/β-catenin signaling regulation. Additionally, it acts as a modulator of osteogenic differentiation in human mesenchymal stem cells (hMSCs).

In experimental studies, XAV939 demonstrates effective inhibition of tankyrase 1 and tankyrase 2 with IC50 values of 5 nM and 2 nM, respectively, tested against purified enzyme assays. It can also enhance osteoblastic differentiation in hMSCs, contributing to increased expression of osteogenic markers and mineralization. Moreover, XAV939 stabilizes axin proteins, thereby promoting degradation of β-catenin and subsequently downregulating Wnt/β-catenin target gene expression at the molecular level.

In disease-related research applications, XAV939 is widely used for investigating diseases associated with aberrant Wnt/β-catenin signaling, such as various cancers, fibrotic diseases, and conditions characterized by diminished bone formation. By selectively inhibiting tankyrase activity and modulating pathway-specific cellular processes, XAV939 serves as an important tool compound for dissecting Wnt pathway-mediated mechanisms and for the preclinical evaluation of novel therapeutics targeting these pathways.

Protocol

Cell experiment: [1]

Cell lines

HCT116 cells

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37°C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20°C for several months.

Reaction Conditions

20 μM, 24 hours

Applications

HCT116 cells were treated with XAV-939, then stained with PI and subjected to flow cytometric analysis or lysed and subjected to immunoblot analysis. The results showed that the number of cells arrest in G1 phase was 71.01%, as compared with the 45.54% of untreated control samples. Western blot analysis revealed that XAV-939 increased the level of AXIN and inhibited the expression of β-catenin.

Animal experiment: [2]

Animal models

Mice

Dosage form

Intraperitoneal injection, 2.5 mg/kg, four times a day

Applications

Treatment of bleomycin challenged mice with XAV-939 reduced dermal thickening by 50% compared with sham-treated, bleomycin challenged mice. The number of myofibroblasts and the hydroxyproline content were also significantly decreased in mice treated with XAV-939.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
