Metabolite Identification
Common Name5,7-dihydroxy-2-(4-hydroxyphenyl)-6-methoxy-4H-chromen-4-one
Description5,7-dihydroxy-2-(4-hydroxyphenyl)-6-methoxy-4h-chromen-4-one is a predicted metabolite generated by BioTransformer¹ that is produced by the metabolism of 5,7-dihydroxy-6-methoxy-2-phenyl-4h-chromen-4-one. It is generated by cyp1a2, cyp2b6, cyp2c9, cyp2c19, cyp2d6, and cyp2e1 enzymes via a p-hydroxylation-of-monosubstituted-benzene reaction. This p-hydroxylation-of-monosubstituted-benzene occurs in humans.

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.
