CHEBI:6909 - metronidazole

Main ChEBI Ontology Automatic Xrefs Reactions Pathways Models
ChEBI Name metronidazole
Definition A member of the class of imidazoles substituted at C-1, -2 and -5 with 2-hydroxyethyl, nitro and methyl groups respectively. It has activity against anaerobic bacteria and protozoa, and has a radiosensitising effect on hypoxic tumour cells. It may be given by mouth in tablets, or as the benzoate in an oral suspension. The hydrochloride salt can be used in intravenous infusions. Metronidazole is a prodrug and is selective for anaerobic bacteria due to their ability to intracellularly reduce the nitro group of metronidazole to give nitroso-containing intermediates. These can covalently bind to DNA, disrupting its helical structure, inducing DNA strand breaks and inhibiting bacterial nucleic acid synthesis, ultimately resulting in bacterial cell death.

Roles Classification
Chemical Role(s): environmental contaminant
Any minor or unwanted substance introduced into the environment that can have undesired effects.
Biological Role(s): antitrichomonal drug
A drug used to treat trichomonas infections.
antibacterial drug
A drug used to treat or prevent bacterial infections.
antimicrobial agent
A substance that kills or slows the growth of microorganisms, including bacteria, viruses, fungi and protozoans.
A xenobiotic (Greek, xenos "foreign"; bios "life") is a compound that is foreign to a living organism. Principal xenobiotics include: drugs, carcinogens and various compounds that have been introduced into the environment by artificial means.
Application(s): antitrichomonal drug
A drug used to treat trichomonas infections.
A compound that, on administration, must undergo chemical conversion by metabolic processes before becoming the pharmacologically active drug for which it is a prodrug.
antibacterial drug
A drug used to treat or prevent bacterial infections.
antiparasitic agent
A substance used to treat or prevent parasitic infections.
radiosensitizing agent
A drug that makes increases the sensitivity of tumour cells to radiation therapy.
antiamoebic agent
An antiparasitic agent which is effective against amoeba, a genus of single-celled amoeboids in the family Amoebidae.
