Title:

Interactions of Monoamine Oxidases with the Antiepileptic Drug Zonisamide: Specificity of Inhibition and Structure of the Human Monoamine Oxidase B Complex.

Journal:

J Med Chem. 2010 Dec 22.

Abstract:

The binding of zonisamide to purified, recombinant monoamine oxidases (MAOs) has been investigated. It is a competitive inhibitor of human MAO B (K(i) = 3.1 +/- 0.3 muM), of rat MAO B (K(i) = 2.9 +/- 0.5 muM), and of zebrafish MAO (K(i) = 30.8 +/- 5.3 muM). No inhibition is observed with purified human or rat MAO A. The 1.8 A structure of the MAO B complex demonstrates that it binds within the substrate cavity.
