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). Purity 98%. MW (observed): 778.94
