简介内容:CDK12-IN-6, a pyrazolotriazine compound, is a powerful inhibitor of CDK12. Its inhibitory activity is significant with an IC50 value of μM when tested at high ATP concentration (2 mM). Notably, CDK12-IN-6 does not exhibit any inhibitory effect on CDK2/Cyclin E (IC50 >20 μM) and CDK9/Cyclin T1 (IC50 >20 μM) when tested under the same high ATP conditions (2 mM) (WO2021116178A1).
