YKL-5-124 TFA 是一种有效的、选择性不可逆CDK7共价抑制剂,对CDK7和CDK7/Mat1/CycH的IC50分别为 53.5 nM 和 9.7 nM。YKL-5-124 TFA 对CDK7的选择性比 CDK9 和 CDK2 高 100 倍以上,并且对 CDK12 和 CDK13 没有活性。YKL-5-124 TFA 诱导强烈的细胞周期停滞,并抑制 E2F 驱动的基因表达,并且对 RNA 聚合酶 II 磷酸化状态几乎没有影响。
生物活性 | YKL-5-124 TFA is a potent, selective, irreversible and covalentCDK7inhibitor withIC50s of 53.5 nM and 9.7 nM forCDK7andCDK7/Mat1/CycH, respectively. YKL-5-124 TFA is >100-fold greater selective forCDK7thanCDK9andCDK2, and inactive againstCDK12andCDK13. YKL-5-124 TFA induces a strong cell-cycle arrest, inhibits E2F-driven gene expression, and exhibits little effect on RNA polymerase II phosphorylation status[1]. |
IC50& Target[1] | CDK7 53.5 nM (IC50) | CDK7/Mat1/CycH 9.7 nM (IC50) | CDK2 1300 nM (IC50) | CDK9 3020 nM (IC50) |

体外研究 (In Vitro) | YKL-5-124 (0-2000 nM; 72 hours; HAP1 cells) treatment causes a dose-dependent increase in G1- and G2/M-phase cells and a corresponding loss of S-phase cells[1]. YKL-5-124 (0-2000 nM; 24 hours; HAP1 WT cells) treatment inhibits CDK1 T-loop phosphorylation, and to a lesser extent CDK2 T-loop phosphorylation in a concentration-dependent fashion[1]. Treatment of cells with YKL-5-124 as a competitor at a concentration of about 30 nM blocks pull-down of CDK7-cyclin H but has no effect on the pull-down of cyclin K-CDK12/13 in HAP1 cells. Treatment with 100 nM YKL-5-124 reduces CDK7-cyclin H binding to bioTHZ1 by >50% at 30 min[1].
