cdc2-cyclin b

NG 52 (NG-52) is a cell-permeable, reversible, and ATP-compatible inhibitor of the cell cycle-regulating kinase Cdc28p and the related Pho85p kinase.

Olomoucine is an ATP-competitive inhibitor of Cdk2 cyclin A, Cdc2 CyclinB, CDK2 CyclinE, CDK5 p35, and ERK1 p44 MAP kinase with IC50s of 7, 7, 7, 3, and 25 µM, respectively. It regulates the cell cycle and exhibits anti-melanin tumor activities.

Seliciclib (Roscovitine) is a potent inhibitor of Cdk2 cyclin E (IC50=0.1 µM). Seliciclib also inhibits Cdk7 cyclin H, Cdk5 p35 and Cdc2 cyclin B (IC50=0.49 0.16 0.65 µM). Seliciclib has antitumor activity.

Purvalanol A (NG-60) is an effective and cell-permeable CDK inhibitor with IC50 of 70 4 35 850 nM for cdk2-cyclin A B E, and cdk4-cyclin D1, respectively.

Purvalanol B (NG 95) is a CDK inhibitor that targets Cdk2 cyclin A, Cdk2 cyclin E, Cdk5 p35, and Cdk2 cyclin B, with IC50 values of 6, 9, 6, and 6 nM, respectively.

CBP501 is a peptide with G2 checkpoint-abrogating activity. G2 checkpoint inhibitor CBP501 inhibits multiple serine threonine kinases, including MAPKAP-K2, C-Tak1, and CHK1, that phosphorylate serine 216 of the dual-specific phosphatase Cdc25C (cell division checkpoint 25 C); disruption of Cdc25C activity results in the inhibition of Cdc25C dephosphorylation of the mitotic cyclin-dependent kinase complex Cdc2 cyclin B, preventing entry into the mitotic phase of the cell cycle.

12-Deoxyphorbol 13-palmitate, a monomer derived from the roots of Euphorbia fischeriana, exhibits notable antitumor activity. This compound induces cell cycle arrest and apoptosis in gastric cancer cells by modulating key cell cycle regulators, such as cyclin B, cyclin A, and CDC2. Additionally, 12-Deoxyphorbol 13-palmitate significantly diminishes liver fibrosis by targeting APOL2 and impairing the APOL2–SERCA2–PERK–HES1 signaling pathway.
