PRODUCT INTRODUCTION
description
Entacapone is a monocarboxylic acid amide that is N,N-diethylprop-2-enamide in which the hydrogen at position 2 is substituted by a cyano group and the hydrogen at the 3E position is substituted by a 3,4-dihydroxy-5-nitrophenyl group. It has a role as an EC 2.1.1.6 (catechol O-methyltransferase) inhibitor, an antiparkinson drug, a central nervous system drug and an antidyskinesia agent. It is a monocarboxylic acid amide, a nitrile, a member of catechols and a member of 2-nitrophenols.
