Lerociclib (G1T38) is a selective and highly potent CDK4/6 inhibitor with anticancer and antitumor activity, inhibits CDK4/CyclinD1 and CDK6/CyclinD3, and inhibits tumor growth in an animal model of endocrine-resistant breast cancer. Due to the poor solubility, for animal studies, the salt form T11345L is recommended.

YKL-5-124, a potent, selective and covalent CDK7 inhibitor with an IC50 of 9.7 nM, 1300 nM and 3020 nM for CDK7/Mat1/CycH, CDK2 and CDK9 respectively, displays biochemical and cellular selectivity for CDK7 over CDK12/13.

Toyocamycin (Vengicide) is an adenosine analog produced by Actinomycetes, functioning as an XBP1 inhibitor and inhibiting IRE1α-induced ATP-dependent XBP1 mRNA cleavage (IC50: 80 nM), and induces apoptosis.

Abemaciclib (LY2835219) is a dual inhibitor of CDK4/6 (IC50=2/10 nM) with selectivity and specificity. Abemaciclib has antitumor activity and is used to treat advanced or metastatic breast cancer.

NVP-LCQ195 (LCQ-195) (AT9311) is a potent inhibitor of CDK1, CDK2, CDK3 and CDK5 (IC50: 1-42 nM).

Abemaciclib methanesulfonate (LY2835219) is a specific and effective inhibitor of CDK4(IC50=2 nM) and CDK6(IC50=10 nM).

YKL-5-124 TFA is a potent, selective, irreversible and covalent inhibitor of CDK7 (IC50s of 53.5 nM and 9.7 nM for CDK7 and CDK7/Mat1/CycH, respectively).

AT7519 Hydrochloride (AT7519 HCl) is a multi-CDK inhibitor for CDK1, 2, 4, 6 and 9.

AT7519 is a kinase inhibitor (IC50: 0.19, 0.044, 0.51, 0.067, 0.66 and 0.018 μM for CDK1/cyclinB, CDK2/CyclinA, CDK2/Cyclin E, CDk4/CyclinD1, CDK6/Cyclin D3, CDk5/p35).

MC180295 ((rel)-MC180295) is a novel, potent, and highly selective CDK9 inhibitor with an IC50 of 5 nM, demonstrating over 22-fold selectivity compared to other CDKs.

Samuraciclib (CT7001) is a potent, selective, and orally active CDK7 inhibitor with an ATP-competitive nature, effectively inhibiting CDK7 with an IC50 of 41 nM. It demonstrates 45-fold, 15-fold (IC50 of 578 nM), 230-fold, and 30-fold selectivity over CDK1, CDK2, CDK5, and CDK9, respectively. Samuraciclib inhibits the growth of breast cancer cell lines with GI50 values of 0.2-0.3 μM and possesses anti-tumor effects [1] [2].

AT7519 is a CDK1/2/4/6/9 inhibitor (IC50: 10-210 nM). It is less effective to CDK3 and little active to CDK7.

GFB-12811 is an orally active, selective, and potent CDK5 inhibitor, used in the study of autosomal dominant polycystic kidney disease.

Samuraciclib (CT7001) hydrochloride hydrate is a potent, selective, ATP-competitive, orally active inhibitor of CDK7 (IC50: 41 nM). It inhibits the growth of breast cancer cell lines (GI50: 0.2-0.3 μM) and exhibits potent antitumor effects.

YKL-5-124 TFA, a potent and selective irreversible covalent inhibitor of CDK7, demonstrates IC50 values of 53.5 nM for CDK7 and 9.7 nM for the CDK7/Mat1/CycH complex. It exhibits over 100-fold selectivity for CDK7 over CDK9 and CDK2, while showing no activity against CDK12 and CDK13. This compound effectively induces cell-cycle arrest, inhibits E2F-driven gene expression, and has minimal impact on the phosphorylation status of RNA polymerase II.

Ibulocydine is a potent CDK inhibitor. Ibulocydine has high activity against Cdk7/cyclin H/Mat1 and Cdk9/cyclin T. Ibulocydine inhibited the growth of HCC cells more effectively than other Cdk inhibitors, including olomoucine and roscovitine, whereas ibulocydine as well as the other Cdk inhibitors and BMK-Y101 minimally influenced the growth of normal hepatocyte cells. Ibulocydine induced apoptosis in HCC cells, most likely by inhibiting Cdk7 and Cdk9. In vitro treatment of HCC cells with ibulocydine rapidly blocked phosphorylation of the carboxyl-terminal domain (CTD) of the large subunit of RNA polymerase II, a process mediated by Cdk7/9. Anti-apoptotic gene products such as Mcl-1, survivin, and X-linked IAP (XIAP) are crucial for the survival of many cell types, including HCC. Following the inhibition of RNA polymerase II phosphorylation, ibulocydine caused rapid down-regulation of Mcl-1, survivin, and XIAP, thus inducing apoptosis. Furthermore, ibulocydine effectively ind......
