Metabolite Identification
Common Name11-Hydroxy-12-methoxydihydrokawain
Description11-Hydroxy-12-methoxydihydrokawain belongs to the class of organic compounds known as kavalactones. These are lactones, which is structurally characterized by a benzene ring and a pyranone moiety, linked to each other to form a 4-methoxy-6-(2-phenylethyl)-2H-pyran-2-one skeleton. Based on a literature review very few articles have been published on 11-Hydroxy-12-methoxydihydrokawain.

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.

General function:
sulfotransferase activity
Specific function:
Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of phenolic monoamines (neurotransmitters such as dopamine, norepinephrine and serotonin) and phenolic and catechol drugs.
