This definition has not yet been approved by a moderator.

A carbazole derivative (3,6-bis[2-(1-methylpyridinium)vinyl]carbazole diiodide) that selectively targets to the G-quadruplex DNA structure, used as a fluorescent probe for cancer cytological diagnosis and with potential antitumor activity. G-quadruplex stabilizer BMVC, preferentially uptaken by cancer cells, binds to and stabilizes the telomeric G-quadruplex structure at the end of DNA; when visualized with fluorescent imaging device, BMVC emits bright fluorescent light and can be used to differentiate tumor cells from normal cells. The BMVC/G-quadruplex complexes also interfere with the activity of telomerase, which is highly active in tumor cells and plays a key role in tumorigenesis while expressed at very low levels in most somatic cells.
