Journal ArticleDOI

Synthetic models of the active site of catechol oxidase: mechanistic studies

Iryna A. Koval, +4 more
- 23 Aug 2006 - 
TL;DR: This critical review extensively discusses the synthetic models of catechol oxidase, with a particular emphasis on the different approaches used in the literature to study the mechanism of the catalytic oxidation of the substrate (catechol) by these compounds.
Journal ArticleDOI

Catecholase activity of a copper(II) complex with a macrocyclic ligand: unraveling catalytic mechanisms.

Iryna A. Koval, +15 more
- 07 Aug 2006 - 
TL;DR: The structure, properties and a mechanism for the catecholase activity of a tetranuclear carbonato-bridged copper(II) cluster with the macrocyclic ligand with a carbonate anion are reported.
Journal ArticleDOI

New didentate bispyrazole ligands forming uncommon eight-ring chelates with divalent copper, zinc and cobalt

Anna M Schuitema, +5 more
- 12 Nov 2001 - 
TL;DR: In this paper, 1,3-bis(5′-methylpyrazol-1′-yl)propane (bpp) and 1, 3-bis (3′, 5′-dimethylpyrazal-1-yl)-propane(bdpp) have been prepared by reacting 2 equiv. of the corresponding potassium pyrazolate with 1 equiv of 1, threedibromopropane.
Journal ArticleDOI

The Dicopper(II) Complex of the Novel Asymmetric Dinucleating Ligand Hpy3asym as a Structural Model of Catechol Oxidase

Iryna A. Koval, +5 more
- 01 May 2003 - 
TL;DR: In this article, an asymmetric dinucleating ligand 2-bis(2-pyridinylmethyl)amino]methyl}-4-methyl-6-{[(pyrinylmethylamino]-methyl}phenol (Hpy3asym) has been designed in order to model the type-3 active site of the copper proteins.
Journal ArticleDOI

Catecholase activity of a μ-hydroxodicopper(II) macrocyclic complex: structures, intermediates and reaction mechanism

Iryna A. Koval, +8 more
- 06 Oct 2005 - 
TL;DR: In this article, a 3D structure of the dicopper(II) complex is presented, which is the first 3D model of the active site of the catechol oxidase.
