Stoichiometry and conditional stability constants of Cu(II) or Zn(II) clioquinol complexes; implications for Alzheimer's and Huntington's disease therapy
(ELSEVIER SCIENCE BV, 2007-05)
Successful trials with 5-chloro-7-iodo-8-hydroxyquinoline (clioquinol, CQ) for Alzheimer’s disease treatment prompted renewed interest in
assessing whether its therapeutic action is related to the coordination of ...
Stoichiometry and conditional stability constants of Cu(II) or Zn(II) clioquinol complexes; implications for Alzheimer's and Huntington's disease therapy
(2007)
Successful trials with 5-chloro-7-iodo-8-hydroxyquinoline (clioquinol, CQ) for Alzheimer's disease treatment prompted renewed interest in assessing whether its therapeutic action is related to the coordination of neurotoxic ...
Redox-changes associated with the glutathione-dependent ability of the Cu(II)-GSSG complex to generate superoxide
(2012)
The intracellularly-occurring Cu(I)-glutathione complex (Cu(I)-[GSH] 2) has the ability to reduce molecular oxygen into superoxide. Removal of such radicals leads to the irreversible conversion of Cu(I)-[GSH] 2 into the ...
Origin of chirality in charge transfer bands of Cu(II) acidates
(Pergamon Press, 1981)
Complexes of Cu(II) with L-aminoacids have positive charge transfer bands in their CD spectra at ca.230 nm and negative at ca. 270 nm. Examination of complexes with L-1,2-diamino propane shows that the positive band is ...
A discrete dinuclear Cu(II)-Gd(III) complex derived from a Schiff base ligand, [CuGd(ems)(NO3)(3)H2O]Cu(ems) (ems : N,N '-ethylene-bis-5-methoxy salicylaldiimine)
(ELSEVIER SCIENCE SA, 2002-06-27)
A Cu(II)-Gd(III) heteronuclear complex with N,N'-ethylene-bis-5-methoxy salicylaldiimine (ems) as ligand has been synthesized. The complex crystallizes in the monoclinic system C2/c space group. The structure consists of ...
Structural versatility of 3d-Ce-III heterometallic coordination polymers using Co-II or Cu-II
(American Chemical Society, 2018)
In the present work, we report the synthesis and characterization of two new heterometallic coordination polymers based on Ce-III and containing Co-II or Cu-II cations, assembled by the bifunctional ligand 1H-imidazole-4 ...
A new copper(II) di-μ2-carboxylato bridged dinuclear complex: [Cu(oda)phen]2 · 6H2O (oda = oxydiacetate, phen = phenanthroline)
(2007)
The oxydiacetate-bridged copper(II) complex [Cu(oda)(1,10-phen)] · 3H2O (oda = oxydiacetate dianion, 1,10-phen = 1,10-phenanthroline) has been characterized. The complex is dinuclear and centrosymmetric with each copper ...
Influence of DMbetaCD on the Interaction of Copper(II) Complex of 6-Hydroxychromone-3-carbaldehyde-3-hydroxybenzoylhydrazine with ctDNA
(American Chemical Society, 2020)
The interaction mechanism between a scarcely soluble copper(II) complex of Cu(II)-6-hydroxychromone-3carbaldehyde-(3'-hydroxy)benzoylhydrazone( CuCHz) in aqueous solution and its DM beta CD complex was studied in the ...
Experimental evidence of the disproportionation equilibrium in copper mixed-valence complexes
(2000)
Experimental evidence for a dismutation equilibrium in the mixed-valence (MV) [Mn+ -M(n+1)+] system type has been elusive and its existence can be established only when the oxidation-reduction processes involved are ...
Cu-II- and Co-II-Based MOFs: {[La2Cu3(mu-H2O)(ODA)(6)(H2O)(3)]center dot 3H(2)O}(n)and {[La2Co3(ODA)(6)(H2O)(6)]center dot 12H(2)O}(n). The Relevance of Physicochemical Properties on the Catalytic Aerobic Oxidation of Cyclohexene
(MDPI, 2020)
The aerobic oxidation of cyclohexene was done using the heterometallic metal organic frameworks (MOFs) {[La2Cu3(mu-H2O)(ODA)(6)(H2O)(3)].3H(2)O}(n)(LaCuODA)) (1) and {[La2Co3(ODA)(6)(H2O)(6)].12H(2)O}(n)(LaCoODA) (2) as ...
