Biological Activity

CDK8/19i is a potent and selective CDK8 and CDK19 inhibitor (IC50 values are 2.9 and 14.1 nM, respectively). CDK8/19i maintains pluripotency of mouse PSCs in culture. It induces the formation of dome-shaped colonies and upregulates Nanog-GFP reporter and endogenous Nanog expression in mouse ESCs in vitro.

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.
