CCT251545 is an orally bioavailable and potent inhibitor of WNT signaling with IC50 value of 5 nM. IC50 value: 5 nM [2] Target: WNT in vitro: CCT251545 is a potent and selective chemical probe for the human Mediator complex-associated protein kinases CDK8 and CDK19 with >100-fold selectivity over 291 other kinases. CCT251545 also reduces phospho-STAT1SER727 levels in SW620 cells with IC50 of 9 nM. CCT251545 is a small-molecule inhibitor of the WNT pathway discovered through cell-based screening. CCT251545 displays potent cell-based activity. CCT251545 alters WNT pathway-regulated gene expression and other on-target effects of modulating CDK8 and CDK19, including expression of genes regulated by STAT1. [1] CCT251545 demonstrates weak inhibition of tankyrase enzymes (TNKS1 IC50 > 10 μM, TNKS2 IC50 = 15.0 ± 0 μM). CCT251545 potently inhibits reporter-based readouts of basal WNT pathway activity in LS174T and SW480 cells in the absence of WNT ligand or other stimulants (IC50 = 0.023 ± 0.011 μM and 0.190 ± 0.030 μM, respectively) and demonstrated potent inhibition of WNT3a ligand-dependent reporter readout in PA-1 cells (IC50 = 0.007 μM).[2] in vivo: CCT251545 as a potent and selective chemical probe suitable for cell-based exploration of the reported context-dependent roles of CDK8 and CDK19 and associated kinase module subunits in human disease and other biological settings.
