human ... COMT(1312)

Application

Tolcapone may be used in COMT-mediated cell signaling studies.
Tolcapone has been used in methyltransferase assay in human embryonic kidney 293 cells.

Biochem/physiol Actions

Inhibition of catechol-O-methyltransferase by tolcapone increases the half-life and bioavailabilty of levodopa. It therefore is an effective adjunctive therapy in patients with Parkinson′s disease with motor response fluctuations.
Orally active catechol-O-methyltransferase (COMT) inhibitor: inhibits both central and peripheral COMT.
Tolcapone is an orally active catechol-O-methyltransferase (COMT) inhibitor. It inhibits both central and peripheral COMT. Tolcapone crosses the blood-brain barrier, and has been used for L-DOPA adjunct therapy in the treatment of Parkinson′s Disease.
