Biological Activity

Binds and inhibits Cdk8 in complex with cyclin C (IC50 ~ 200 nM). Enhances IL-10 production in activated human and murine macrophages and dendritic cells (EC50 is approximately 1 μM for IL-10 production in bone marrow-derived dendritic cells). Also inhibits CDK19 in complex with cyclin C.

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.
