Metabolite Identification
Common NameMetronidazole
DescriptionMetronidazole, also known as metrogel-vaginal or flagyl, belongs to the class of organic compounds known as nitroimidazoles. Nitroimidazoles are compounds containing an imidazole ring which bears a nitro group. Metronidazole is a moderately basic compound (based on its pKa). Metronidazole is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound.

Enzymes

General function:
Involved in monooxygenase activity
Specific function:
Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It performs a variety of oxidation reactions (e.g. caffeine 8-oxidation, omeprazole sulphoxidation, midazolam 1'-hydroxylation and midazolam 4-hydroxylation) of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Acts as a 1,8-cineole 2-exo-monooxygenase. The enzyme also hydroxylates etoposide.

In the epoxidation of arachidonic acid it generates only 14,15- and 11,12-cis-epoxyeicosatrienoic acids. It is the principal enzyme responsible for the metabolism the anti-cancer drug paclitaxel (taxol).
