CDK12-IN-2是一种高效、选择性的纳摩尔级别的CDK12 抑制剂 (IC50=52 nM)，具有良好的物理化学性质。CDK12-IN-2也是一种强的CDK13抑制剂，因为CDK13是CDK12最接近的同源物。CDK12-IN-2对CDK12的激酶选择性比CDK2、9、8和7高。CDK12-IN-2抑制RNA polymerase II 的 C端Ser2磷酸化。CDK12-IN-2可以作为一种很好的化学探针用于CDK12的功能研究。

Background:

CDK12-IN-2 is a potent, selective and nanomolar CDK12 inhibitor (IC50=52 nM) with good physicochemical properties. CDK12-IN-2 is also a strong CDK13 inhibitor due to CDK13 is the closest homologue of CDK12. CDK12-IN-2 shows excellent kinase selectivity for CDK12 over CDK2, 9, 8, and 7. CDK12-IN-2 inhibits the phosphorylation of Ser2 in the C-terminal domain of RNA polymerase II. CDK12-IN-2 can be used an excellent chemical probe for functional studies of CDK12[1].

CDK12-IN-2 inhibits the phosphorylation of the CTD Ser2 in SK-BR-3 cells at low submicromolar concentrations, it inhibits C-terminal domain ser2 phosphorylation with an IC50 of 185 nM. And CDK12-IN-2 exhibits a growth inhibition with an IC50 of 0.8 μM in SK-BR-3 cells[1].CDK12-IN-2 exhibits time dependency for CDK12 inhibition, the IC50 value for CDK12-IN-2 are 0.0078 μM, 0.042 μM, 0.057 μM,and 0.059 μM, for 0h, 1h, 2h and 5h respectively[1].
