Nitroimidazoles are the group of

Imidazole undergoes a nitration reaction with a mixture of nitric acid and sulfuric acid to give 5-nitroimidazole.

From the chemistry perspective, nitroimidazole antibiotics can be classified according to the location of the nitro functional group. Structures with names 4- and 5-nitroimidazole are equivalent from the perspective of drugs since these tautomers readily interconvert. Drugs of the 5-nitro variety include metronidazole, tinidazole, nimorazole, dimetridazole, pretomanid, ornidazole, megazol, and azanidazole. Drugs based on 2-nitroimidazoles include benznidazole and azomycin.^[3]
