Topoisomerase II inhibitor and intracellular ion chelator. Bridges and stabilizes an interface between two ATPase promoters to inhibit topoisomerase II activity. Cardioprotective when co-administered with doxorubicin; decreases formation of reactive oxygen species (ROS) and activates the PI3K/Akt survival pathway.

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.
