Biological Activity

XAV939 is an inhibitor of Tankryases with IC50 values of 11 and 4nM for Tankyrase 1 and Tankyrase 2, respectively. It stimulates beta-catenin degradation by stabilizing axin, resulting in the inhibition of the canonical Wnt pathway. Wnt proteins act on a variety of stem cells that include neural, mammary and embryonic stem cells. XAV939 increases the protein levels of the axin-GSK3β complex and promotes the degradation of β-catenin in SW480 cells. In addition, XAV939 inhibits growth of DLD-1 cells, an APC-deficient colorectal cancer cell line.

Results Wnt inhibitor XAV 939 was significantly inhibited the up-regulation of Wnt and phosphorylated-β-catenin and increased phosphorylated-GSK-3β expression in the hippocampus in ISA and SEA groups, as compared with the control group at 5 weeks (Figure 4 A, B, C, p < 0.05).

Results As shown in Figure 3, the expression levels of Wnt3a and β-catenin (Figure 3A, C, p < 0.05) were significantly reduced after Wnt inhibitor XAV 939 treatment, while GSK-3β expression level was dramatically increased in ISAI and SEAI groups (Figure 3B, p < 0.05).

Results When rats were treated with Wnt inhibitor XAV 939 at 30 min before anesthesia, the impairment of brain could relieve. These findings suggested that impairment of learning and memory in P7 rats may through the Wnt signaling pathway.
Cell Experiment
Cell lines B-T549, MDA-MB-231, HCC-1143 and HCC-1937 cell lines
Preparation method Cell viability assay. Cells were seeded at 20,000 cells/well into 96-well plates. After overnight incubation, cells were treated with DMSO or each Wnt inhibitor (iCRT-3, 75 μM; iCRT-5, 200 μM; iCRT-14, 50 μM; IWP-4, 5 μM and XAV-939, 10 μM) for 48 hours. Cell viability was determined using the Cell Titer-Glo luminescent cell viability assay kit (Promega) according to the manufacturer’s instructions. Luminescence was measured using FLUOstar microplate reader. All treatments were performed in triplicate, and each experiment was repeated three times.

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
