Informations sur le gène

human ... COMT(1312)

Application

3,5-Dinitrocatechol (3,5-DNC) has been used in the preparation of the molybdenum (VI)-(3,5-DNC) complex. It has also been used as a catechol-O-methyltransferase (COMT) inhibitor and as a positive control for screening human COMT inhibition.
Chelating reagent used in a sensitive (μM) assay for vanadium.

Actions biochimiques/physiologiques

Selective inhibitor of catechol O-methyl transferase (COMT); penetrates the blood brain barrier and is useful both orally and parenteraly in experiments where inhibition of COMT in the central nervous system is required.

The catecholamine, dopamine (DA), is synthesized from 3,4-dihydroxy-L-phenylalanine (L-DOPA) by aromatic L-amino acid decarboxylase (AADC). Dopamine metabolism is regulated by monoamine oxidase (MAO) and catechol-O-methyltransferase (COMT). To measure dopaminergic metabolism, we used microdialysis with radiometric detection to monitor L-[β-(11)C]DOPA metabolites
