Additional Information:

Tolcapone is a catechol O-methyltransferase inhibitor (COMT), inhibiting both brain and peripheral enzymes (1). This compound is a potent inhibitor of alpha-synuclein and beta-amyloid oligomerization and fibrillogenesis protecting against extracellular toxicity (2), also binds to transthyretin (TTR) with high affinity (21 to 58 nM) and inhibits TTR aggregation in human plasma and prevents TTR-induced cytotoxicity in vitro. It also stabilizes TTR in mice and humans in vivo (3), inhibits O-methylation of exogenous polyphenols such as EGCG (4), is cell permeable and orally bioavailable.
