Biological Activity for AZ 20

AZ 20 is a potent and selective ATR kinase inhibitor (IC50 = 5 nM). Exhibits 7.6-fold selectivity over mTOR and selectivity over a panel of 442 kinases, including ATM kinase, PI3-K isoforms, and DNA-PK. Inhibits cell growth in cell lines with high baseline levels of replication stress. Displays antitumor effects in vivo.

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. 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.
