Same chemical strategy. Under aerobic conditions, host cells produce nitric oxide (NO) via
the enzyme inducible nitric oxide synthase (iNOS). NO can kill replicating bacteria. Under
hypoxic conditions, bacteria enter a state of nonreplicative persistence and host cell NO
production is limited. Certain nitroimidazoles can generate NO (and other reactive nitrogen
intermediates) within the bacteria under both aerobic and hypoxic conditions. Under hypoxic
conditions, these reactive nitrogen intermediates contribute to killing the bacteria.
