Metabolite Identification
Common Name2-Hydroxyibuprofen
Description2-Hydroxyibuprofen, also known as ibuprofen OH, belongs to the class of organic compounds known as phenylpropanoic acids. Phenylpropanoic acids are compounds with a structure containing a benzene ring conjugated to a propanoic acid. 2-Hydroxyibuprofen is a metabolite of ibuprofen. 2-Hydroxyibuprofen is an extremely weak basic (essentially neutral) compound (based on its pKa). 2-hydroxyibuprofen can be biosynthesized from ibuprofen through the action of the enzymes cytochrome P450 3A4, cytochrome P450 2C8, cytochrome P450 2C19, and cytochrome P450 2C9. In humans, 2-hydroxyibuprofen is involved in ibuprofen metabolism pathway. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) used for relief of symptoms of arthritis, fever, as an analgesic (pain reliever), especially where there is an inflammatory component, and dysmenorrhea. Ibuprofen is known to have an antiplatelet effect, though it is relatively mild and somewhat short-lived when compared with aspirin or other better-known antiplatelet drugs.

Enzymes

General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isoform glucuronidates bilirubin IX-alpha to form both the IX-alpha-C8 and IX-alpha-C12 monoconjugates and diconjugate. Is also able to catalyze the glucuronidation of 17beta-estradiol, 17alpha-ethinylestradiol, 1-hydroxypyrene, 4-methylumbelliferone, 1-naphthol, paranitrophenol, scopoletin, and umbelliferone.
