Entacapone

Entacapone is a potent and specific peripheral catechol-O-methyltransferase (COMT) inhibitor with an IC50 of 151 nM. Entacapone is also a potential obesity-related gene (FTO) inhibitor that can inhibit FTO demethylation activity and be used in the study of metabolic diseases.

cis-Entacapone is a metabolite of the catechol-O-methyltransferase (COMT) inhibitor entacapone. It is also a potential impurity found in commercial preparations of entacapone and a degradant of entacapone formed by UV light exposure.

Entacapone acid (AG 1290) is a selective and reversible inhibitor of catechol-O-methyltransferase(COMT).

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.
