Metabolite Identification
Common NameHydroxycotinine
DescriptionHydroxycotinine belongs to the class of organic compounds known as pyrrolidinylpyridines. Pyrrolidinylpyridines are compounds containing a pyrrolidinylpyridine ring system, which consists of a pyrrolidine ring linked to a pyridine ring. It is also excreted as a glucuronide conjugate (3HC-Gluc). Hydroxycotinine is a strong basic compound (based on its pKa). hydroxycotinine can be biosynthesized from cotinine through its interaction with the enzyme cytochrome P450 2A6. In humans, hydroxycotinine is involved in nicotine metabolism pathway. Hydroxycotinine (3HC) is the main nicotine metabolite detected in smokers urine. Quantitatively, the most important metabolite of nicotine in most mammalian species is cotinine. 3HC and 3HC-Gluc account for 40-60% of the nicotine dose in urine.

Enzymes

General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGTs are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isozyme is active on polyhydroxylated estrogens (such as estriol, 4-hydroxyestrone and 2-hydroxyestriol) and xenobiotics (such as 4-methylumbelliferone, 1-naphthol, 4-nitrophenol, 2-aminophenol, 4-hydroxybiphenyl and menthol). It is capable of 6 alpha-hydroxyglucuronidation of hyodeoxycholic acid.

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. Its unique specificity for 3,4-catechol estrogens and estriol suggests it may play an important role in regulating the level and activity of these potent and active estrogen metabolites. Is also active with androsterone, hyodeoxycholic acid and tetrachlorocatechol (in vitro).
