CCT251545( CCT 251545 | CCT-251545 )
Catalog No. M12536 CAS No. 1661839-45-7
CCT251545 is a potent, orally bioavailable inhibitor of Wnt signaling with IC50 of 5 nM, also is a potent and selective chemical probe for CDK8 and CDK19 with >100-fold selectivity over 291 other kinases; potently inhibits reporter-based readouts of basal WNT pathway activity in LS174T and SW480 cells in the absence of WNT ligand with IC50 of 23 and 190 nM, respectively.
Purity : >98% (HPLC)

In VitroCCT251545 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.
