Metabolite Identification
Common NameR-7-Hydroxywarfarin
DescriptionR-7-Hydroxywarfarin belongs to the class of organic compounds known as homoisoflavones. These are homoisoflavonoids with a structure based on the chromone system. Chromone is a bicyclic compound consisting of a 1-benzopyran, which bears a ketone group at the 4-position. R-7-Hydroxywarfarin is only found in individuals that have used or taken Warfarin. R-7-Hydroxywarfarin is an extremely weak basic (essentially neutral) compound (based on its pKa).

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.
