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

More than 50% of patients with Parkinson's disease develop motor response fluctuations (the "wearing off" phenomenon) after more than five years of levodopa therapy. Inhibition of catechol-O-methyltransferase by tolcapone has been shown to increase levodopa bioavailability and plasma elimination half

Tolcapone (Tasmar) is a selective, reversible inhibitor of peripheral and central catechol-O-methyltransferase (COMT). Results of well designed studies indicate that oral tolcapone is an effective adjunct to levodopa plus a peripheral dopa-decarboxylase inhibitor (DDCI) in patients with fluctuating Parkinson's disease.

Catechol-O-methyltransferase (COMT) plays an important role in the deactivation of catecholamine neurotransmitters and hormones. Inhibitors of COMT, such as tolcapone and entacapone, are used clinically in the treatment of Parkinson's disease. Discovery of novel inhibitors has been hampered by a
