Biological Activity

ATP-competitive cyclin-dependent kinase (cdk) inhibitor (reported IC50 values are 0.034 - 0.75, 0.24 - 1.2, 0.25 - 1.1 and 0.46 - 1 μM for cdk9, cdk2, cdk1 and cdk5, respectively). Also inhibits mitogen-activated protein kinase-activated protein kinase-2 (MK2; IC50 = 171 nM). Prevents initiation of DNA replication. Inhibits cell proliferation in a variety of human cell lines and induces apoptosis in a p53-independent manner in vivo.

Cell Cycle & DNA Damage Repair

Cell Cycle & DNA Damage Repair Poster

In normal cells, each stage of the cell cycle is tightly regulated, however in cancer cells many genes and proteins that are involved in the regulation of the cell cycle are mutated or over expressed. Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the stages of the cell cycle and DNA repair. It also highlights strategies for enhancing replicative stress in cancer cells to force mitotic catastrophe and cell death.
