Antibacterial activity of GO 10213, a nitroimidazole derivative.

Compound GO 10213, a 5-nitroimidazole substituted at the 2 position, is more active against aerobic, microaerophilic, and anaerobic bacteria than metronidazole. The MICs for Salmonella typhimurium (2 to 128 micrograms/ml), Campylobacter spp. (0.06 to 16 micrograms/ml) and Bacteroides spp. (0.03 to 0.25 micrograms/ml) are definitely lower than those of metronidazole. Niridazole, a 5-nitrothiazole, is still more active.
