Biological Activity

Mre11-Rad50-Nbs1 (MRN)-ATM pathway inhibitor that blocks the 3' and 5' exonuclease activity associated with Mre11. Prevents ATM activation in response to double strand breaks (IC50 = 12 μM) and induces G2 cell cycle arrest. Also blocks homology-directed repair in vitro.

Compound Libraries

Mirin is also offered as part of the Tocriscreen Plus and Tocriscreen Epigenetics Toolbox. Find out more about compound libraries available from Tocris.

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.
