3-O-Methyltolcapone D7 (Ro 40-7591 D7) is a deuterium labeled 3-O-Methyltolcapone. 3-O-Methyltolcapone (Ro 40-7591) is a metabolite of Tolcapone which is a potent COMT inhibitor. Tolcapone crosses the blood-brain barrier and can be used for treatment of P
3-O-Methyltolcapone (Ro 40-7591) is a metabolite of Tolcapone which is a potent COMT inhibitor. Tolcapone crosses the blood-brain barrier and can be used for treatment of Parkinson's disease.
Entacapone sodium salt inhibits catechol-O-methyltransferase(COMT) with similar IC50 in different tissues including live, duodenum, kidney and lung, but entacapone is more active than tolcapone in those tissues. Entacapone (< 100 μM) is a potent inhibitor of α-syn and β-amyloid (Aβ) oligomerization and fibrillogenesis, and also protects against extracellular toxicity induced by the aggregation of both proteins in PC12 cells.Entacapone sodium salt is a specific, potent, peripherally acting catechol-O-methyltransferase (COMT) inhibitor with IC50 of 151 nM for PD treatment.
Nebicapone is a reversible catechol-O-methyltransferase (COMT) inhibitor and is mainly metabolized by glucuronidation. Nebicapone is mainly peripherally acting inhibitor that decreases the biotransformation of L-DOPA to 3-O-methyl-DOPA by inhibition of CO
