Tankyrase-IN-2 is a selective, potent and orally active inhibitor of tankyrase with IC50s of 10, 7, and 710 nM for TNKS1, TNKS2 as well as PARP1, respectively
YW1128 is an inhibitor of Wnt/β-catenin signaling with an IC50 value of 4.1 nM in a reporter assay.1 It decreases protein levels of β-cateninin the presence of the GSK3β inhibitor lithium chloride and increases protein levels of Axin1 in HEK293 cells. YW1128 decreases lipid accumulation and the expression of gluconeogenic and lipogenic genes in Huh7 cells. It decreases the hepatic expression of Wnt target genes, improves glucose tolerance, and prevents body weight increases and hepatic lipid accumulation in mice fed a high-fat diet, but not mice fed normal chow, when administered at a dose of 40 mg/kg every other day for 11 weeks.References1.

Wnt signaling is required for direct multiple biological processes and also plays key roles in the pathogenesis of various diseases. Cyclic AMP response element-binding protein (CREB) is a transcription factor that is a member of the leucine zipper family of DNA binding proteins. This protein binds as a homodimer to the cAMP-responsive element, an octameric palindrome. The protein is phosphorylated by several protein kinases, and induces transcription of genes in response to hormonal stimulation of the cAMP pathway. Via generating a transcriptionally active complex with β-catenin, CREB acts as a mediator of Wnt signaling.ICG-001 is an inhibitor of β-catenin CREB mediated transcription. The direct cellular target of ICG-001 is CREB. the inhibitory IC50of ICG-001 against β-catenin CREB mediated transcription was 3 μM. ICG-001 treatment at the concentration of 25 μM for 24h significantly increased caspase activity in both colon cancer cell lines SW480 and HCT116 cell lines but not in normal colonic epithelial cells CCD-841Co. In a cell growth inhibition assay, the IC50s of ICG-001 against SW480 and HCT116 cells were 4.43 μM and 5.95 μM, respectively.In a SW620 nude mouse xenograft model, an water-soluble analog of ICG-001 given at the dose of 150 mg kg i.v. once in every 2 days dramatically suppressed tumor growth. In a bleomycin-induced pulmonary fibrosis mice model, ICG-001 given at the dose of 5 mg kg per day reversed pulmonary fibrosis. In a rat myocardial infarction model, ICG-001 was administrated subcutaneously at the dose of 50 mg kg day for 10 days which significantly improved cardiac contractile function after myocardial infarction in the rats.
