Biological Activity

Potent, ATP-competitive dual cdc7/cdk9 inhibitor (IC50 values are 10 and 34 nM respectively) that prevents initiation of DNA replication. Inhibits cell proliferation in a variety of human cell lines (IC50 ~ 0.86 - 5.87 μM) and induces apoptosis in a p53-independent manner in vivo. Also inhibits mitogen-activated protein kinase-activated protein kinase-2 (MK2) (IC50 = 171 nM).

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.
