产品描述

Entacapone is a second-generation catechol-O-methyltransferase (COMT) inhibitor that potently inhibits rat liver total COMT with the half maximal inhibition concentration IC50 and inhibition constant Ki values of 20.1 nM and 10.7 nM respectively. The IC50 values of entacapone against rate liver soluble COMT (S-COMT) and rat liver membrane-bound COMT (MB-COMT) are 14.3 nM and 73.3 nM respectively [1].

Entacapone has succbe used as an adjunct to standard levodopa-dopa decarboxylase inhibitor therapy in patients with Parkinson’s disease (PD), for its abilities to increase the bioavailability of levodopa by inhibiting the generation of 3-O-methyldopa and to prolong the duration and clinical benefit of levodopa [1].
