Background

Entacapone, a nitrocatechol compound, is a selective and reversible inhibitor of catechol-O-methyltransferase (COMT), a Mg2+-dependent enzyme involved in the metabolism of catecholamines and catechol compounds, with the half maximal inhibition concentration IC50 and inhibition constant Ki values of 20.1 nM and 10.7 nM respectively [1 & 2].

The nitro group at the position ortho to the hydroxyl group in the chemical structure of entacapone has been identified as a critical component for its potency and ability to inhibit COMT [2].

Entacapone is an FDA-approved COMT inhibitor for use as an adjunct to levodopa therapy in patients’ with Parkinson’s disease, where it increases both the peripheral and central availability of levodopa [2].
