Metabolite Identification
Common NameEntacapone
DescriptionEntacapone, also known as comtan or comtess, belongs to the class of organic compounds known as hydroxycinnamic acids and derivatives. Hydroxycinnamic acids and derivatives are compounds containing an cinnamic acid (or a derivative thereof) where the benzene ring is hydroxylated. Entacapone is a drug which is used as an adjunct to levodopa / carbidopa in the symptomatic treatment of patients with idiopathic parkinson's disease who experience the signs and symptoms of end-of-dose "wearing-off". Based on a literature review a significant number of articles have been published on Entacapone.

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the oxidative deamination of biogenic and xenobiotic amines and has important functions in the metabolism of neuroactive and vasoactive amines in the central nervous system and peripheral tissues. MAOB preferentially degrades benzylamine and phenylethylamine.
Gene Name:
MAOB
Uniprot ID:
P27338
Molecular weight:
58762.475
General function:
Involved in magnesium ion binding
Specific function:
Catalyzes the O-methylation, and thereby the inactivation, of catecholamine neurotransmitters and catechol hormones. Also shortens the biological half-lives of certain neuroactive drugs, like L-DOPA, alpha-methyl DOPA and isoproterenol.
Gene Name:
COMT
Uniprot ID:
P21964
Molecular weight:
30036.77
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 has specificity for phenols.
