cdk12 in 3

CDK12-IN-3 is a selective and potent CDK12 inhibitor with anti-tumor activity, which can be used to study malignant tumors.

CDK12/13-IN-3 (Compound 12b) is an orally active CDK inhibitor targeting CDK12 and CDK13, with IC50 values of 107.4 nM and 79.4 nM, respectively. This compound inhibits the phosphorylation of Ser2 on the CTD of RNA polymerase II, induces DNA damage, and downregulates the gene expression involved in the DNA damage response (DDR). CDK12/13-IN-3 exhibits antiproliferative effects against various cancer cells with nanomolar IC50 values. In mouse models, it demonstrates antitumor activity, favorable pharmacokinetic properties, and an oral bioavailability of 53.6%.

SY-5609 (CDK7-IN-3) is a selective non-covalent CDK7 inhibitor (Kd value is 0.07 nM), with weak inhibitory activity against CDK2, CDK9 and CDK12 with IC50 values ​​of 5.5, 1.9 and 1.7 μM, respectively, and has anti-tumor activity and inhibits cell apoptosis.

CDK7 12-IN-1 is a selective inhibitor of CDK7 (IC50: 3 nM) and CDK12 (IC50: 277 nM) and effectively inhibits tumor growth.

CDK HDAC-IN-3 is an orally active dual inhibitor of HDACs and CDKs, offering potent and selective inhibition of CDK9, CDK12, CDK13, HDAC1, HDAC2, and HDAC3, with IC50 values of 98.32 nM, 98.85 nM, 100 nM, 62.12 nM, 93.28 nM, and 82.87 nM, respectively, and is applicable in the treatment of acute myeloid leukemia (AML) [1].
