Binds and stabilizes G-quadruplexes, inducing DNA damage and cell cycle arrest (Kd = 490 nM); targets the proto-oncogene Src, reducing Src protein abundance and Src-dependent motility in human breast cancer cells. Also targets telomeric G-quadruplexes, inducing telomerase dysfunction. Activates the DNA-dependent protein kinase catalytic sunbunit (DNA-PKcs).

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.
