Metabolite Identification
Common NameXanthotoxol
DescriptionXanthotoxol, also known as 8-hydroxypsoralen, belongs to the class of organic compounds known as 8-hydroxypsoralens. These are psoralens containing a hydroxyl group attached at the C8 position of the psoralen group. It is one of the major active ingredients in Cnidium monnieri. Xanthotoxol is an extremely weak basic (essentially neutral) compound (based on its pKa). Xanthotoxol exists in all living organisms, ranging from bacteria to humans. Outside of the human body, Xanthotoxol has been detected, but not quantified in, several different foods, such as parsley, herbs and spices, fats and oils, fruits, and green vegetables. This could make xanthotoxol a potential biomarker for the consumption of these foods. Xanthotoxol O-methyltransferase (8-hydroxyfuranocoumarin 8-O-methyltransferase) is an enzyme that uses S-adenosyl methionine and xanthotoxol to produce S-adenosylhomocysteine and O-methylxanthotoxol (xanthotoxin or methoxsalen). Xanthotoxol is a potentially toxic compound. Xanthotoxol is a furanocoumarin.

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.
