IC50 & Target[1][2]
IC50: 5 nM (WNT, 7dF3 cells)
体外研究(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-STAT1 levels in SW620 cells with an IC50 of 9 nM.
CCT251545 displays potent cell-based activity.
