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.

Solutions may be stored for several days at 4 °C.

Organotypic primary cell cultures of fetal rat brain were used as a model system to study the effect of COMT inhibitors on the cerebral metabolic conversions of fluoro-DOPA enantiomers. The selective COMT inhibitors OR 486 and CGP 28014 were used

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

Catechol-O-methyltransferase (COMT) has an important role in the extraneuronal inactivation of catecholamine neurotransmitters and drugs with a catechol structure. Two novel COMT inhibitors, OR-462 and OR-486, were highly effective (IC50 = 18 and 12 nM, respectively) and selective in inhibiting
