CDK12-IN-E9 是一种有效的选择性共价CDK12抑制剂和非共价CDK9抑制剂,同时避免了 ABC 转运蛋白介导的外排。CDK12-IN-E9 对 CDK7/CyclinH 复合物的结合能力较弱,IC50>1 μM。
生物活性 | CDK12-IN-E9 is a potent and selective covalentCDK12inhibitor and a non-covalentCDK9inhibitor, while avoiding ABC transporter-mediated efflux. CDK12-IN-E9 has weak binding ability to CDK7/CyclinH complex with an IC50>1 μM[1]. |
IC50& Target[1] | CDK12 | CDK9/cyclinT1 23.9 nM (IC50) | cdk2/cyclin A 932 nM (IC50) | CDK7/Cyclin H/MNAT1 1210 nM (IC50) |

体外研究 (In Vitro) | CDK12-IN-E9 (E9; 10 nM-10 μM; 72 hours; Kelly, LAN5, SK-N-BE2, PC-9, NCI-H82 and NCI-H3122 cells) treatment shows potent antiproliferative activity in THZ1RNB and lung cancer cells, with IC50values ranging from 8 to 40 nM[1]. CDK12-IN-E9 (E9; 0-3000 nM; 6 hours; Kelly, PC-9, and NCI-H82 cells) treatment leads to a dose-dependent decrease in phosphorylated and total RNAPII in THZ1rNB and lung cancer models, accompanied by decreased MYC and MCL1 expression[1]. CDK12-IN-E9 also results in increased PARP cleavage, and an increase in the subGI population in THZ1rlung cancer cells, while in NB cells, more of a G2/M arrest is seen after a 24-hr exposure to CDK12-IN-E9[1].
Cell Proliferation Assay[1] Cell Line: | Kelly, LAN5, SK-N-BE2, PC-9, NCI-H82 and NCI-H3122 cells | Concentration: | 10 nM-10 μM | Incubation Time: | 72 hours | Result: | Showed potent antiproliferative activity in THZ1RNB and lung cancer cells, with IC50values ranging from 8 to 40 nM. |
Western Blot Analysis[1] Cell Line: | Kelly, PC-9, and NCI-H82 cells | Concentration: | 0 nM, 30 nM, 100 nM, 300 nM, 1000 nM, 3000 nM | Incubation Time: | 6 hours | Result: | Led to a dose-dependent decrease in phosphorylated and total RNAPII in THZ1rNB and lung cancer models. |
