Description | Tolcapone(Ro 40-7592) is an orally active selective, potent catechol-O-methyltransferase (COMT) inhibitor. IC50 value:Target: COMTTolcapone inhibits both central and peripheral COMT. Tolcapone caused a rapid and reversible inhibition of COMT activity in erythrocytes in parallel with a dose-dependent decrease in the formation of 3-OMD. Tolcapone increased the area under the concentration-time curve and elimination half-life of levodopa. Tolcapone crosses the blood-brain barrier, and has been used for L-DOPA adjunct therapy in the treatment of Parkinson's disease. |
