Gene Information

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.

Biochem/physiol Actions

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.

Novel bisubstituted catechols were found to be potent and highly selective COMT inhibitors in vitro. One of them, OR-462 (3-(3,4-dihydroxy-5-benzylidene)-2,4-pentanedione), was studied also in vivo. When administered to rats orally together with levodopa and carbidopa, OR-462 greatly improved the bioavailability
