CCT251545 (1661839-45-7) 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.
