The kinetics of inhibition by BIA 3-335 (1-[3,4-dihydroxy-5-nitrophenyl]-3-(N-3'-trifluormethylphenyl)-piperazine- 1-propanone dihydrochloride) were characterized using recombinant rat soluble COMT.

In the present study we have characterized the role of COMT using COMT-deficient mice in conditions where DAT is inhibited by 1-[2-[bis (4-fluorophenyl) methoxy] ethyl]-4-(3-phenylpropyl)-piperazine (GBR 12909) or cocaine.

Acta Crystallogr D Biol Crystallogr. 2001 Jun;57(Pt 6):906-8. Epub 2001 May 25.

Soluble rat COMT was expressed in Escherichia coli and the recombinant protein was crystallized with a new tight-binding inhibitor, BIA 3-335 [1-(3,4-dihydroxy-5-nitrophenyl)-3-(n-3'-trifluoromethylphenyl) piperazine- 1-propanone dihydrochloride].
