CCT251545 是一种口服生物有效的WNT抑制剂, 在 7dF3 细胞中对 WNT 抑制作用的IC50值为 5 nM。CCT251545 是一种选择性化学探针,用于探索 CDK8 和 CDK19 在人类疾病中的作用。
生物活性 | CCT251545 is an orally bioavailable and potent inhibitor ofWNTsignaling with anIC50of 5 nM in 7dF3 cells[1]. CCT251545 is a selective chemical probe for exploring the role ofCDK8andCDK19in human disease[2]. |
IC50& Target | IC50: 5 nM (WNT, 7dF3 cells)[1] |
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 IC50of 0.035 μM[1]. CCT251545 has weak inhibition of tankyrase enzymes (TNKS1 IC50>10 μM, TNKS2 IC50= 15.0)[1]. 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[2]. CCT251545 alters WNT pathway-regulated gene expression and other on-target effects of modulating CDK8 and CDK19, including expression of genes regulated by STAT1[2]. CCT251545 also reduces phospho-STAT1SER727levels in SW620 cells with an IC50of 9 nM[2]. CCT251545 displays potent cell-based activity[2].
