Nitroimidazoles are
imidazole heterocycles with a nitro group that have been
used to combat anaerobic bacterial and parasitic infections.
Perhaps the most common example is metronidazole (Flagyl ®). Other heterocycles such
as nitrothiazoles (thiazole) are also used for this purpose.
Nitroheterocycles may be reductively activated in hypoxic
cells, and then undergo redox recycling or decompose to toxic products.
