Description

CCT251545 is a potent small-molecule inhibitor of WNT signaling with good oral pharmacokinetics. 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. In contrast to type II inhibitors of CDK8 and CDK19, 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.

How to use

In Vitro:

CCT251545 potently inhibits WNT pathway activity in COLO205-F1756 clone 4 (an APC -mutant human colorectal cancer cell line engineered to express a modified luciferase-based WNT reporter construct) with an IC50 of 0.035 μM. CCT251545 has weak inhibition of tankyrase enzymes (TNKS1 IC50 > 10 μM, TNKS2 IC50 = 15.0). 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 alters WNT pathway-regulated gene expression and other on-target effects of modulating CDK8 and CDK19, including expression of genes regulated by STAT1. CCT251545 also reduces phospho-STAT1SER727 levels in SW620 cells with an IC50 of 9 nM. CCT251545 displays potent cell-based activity.

In Vivo:

CCT251545 (70mg/kg; p.o.; twice daily) causes an inhibition of tumor growth in NCr athymic mice bearing established SW620 human colorectal cancer xenografts.
