Kenpaullone
Biological Activity
Potent inhibitor of CDK1/cyclin B and GSK-3β (IC50 values are 0.4 and 0.23 μM respectively). Also inhibits CDK2/cyclin A, CDK2/cyclin E and CDK5/cyclin/p35 (IC50 values are 0.68, 7.5 and 0.85 μM respectively). Selective over c-src (IC50 = 15 μM), casein kinase 2 (IC50 = 20 μM), ERK1 (IC50 = 20 μM), ERK2 (IC50 = 9 μM) and a range of other protein kinases (IC50 values > 35 μM). Generates induced pluripotent stem cells (iPSCs) from somatic cells when used in combination with reprogramming factors; can replace Klf4.

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.
