Biological Activity

Potent and selective CDK9 inhibitor (IC50 = 44 nM at CDK9-cyclin T1). Inhibits other CDKs in the micromolar range (IC50 values are 2.4, 5.5, 9.2, >10 and >10 μM for CDK2-cyclin A, CDK1-cyclin B1, CDK4-cyclin D1, CDK6-cyclin D3 and CDK7-cyclin H-MAT1, respectively). Inhibits P-TEFb-dependent in vitro transcription. Induces apoptosis in vitro and in vivo in combination with BI 894999.

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.
