Oxidative DNA damage induced by S(IV) in the presence of Cu(II) and Cu(I) complexes
(Sociedade Brasileira de Química, 2009)
The DNA damage induced by S(IV) in the presence of some Cu(II) complexes in air saturated solution was investigated. The addition of S(IV) to an air saturated solution containing CuII GGA (GGA = glycylglycyl-L-alanine), ...
Thermal and electrochemical studies of Cu(II) 8-hydroxyquinoline organophilic montmorillonite
The thermal and electrochemical behavior of montmorillonite clay-8-hydroxyquinoline (8-HQ) film was studied in the absence and presence of aqueous Cu(II) ions. The suggested formation of the ternary complex type: ...
Stoichiometry and conditional stability constants of Cu(II) or Zn(II) clioquinol complexes; implications for Alzheimer's and Huntington's disease therapy
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 ...
Induced distant cotton effects in mixed Cu(II) complexes of amino and hydroxy acids and heterocyclic ligands
(Pergamon Press Ltd., 1981)
Mixed 1:1:1 complexes of proline or aspartic acid with Cu(II) and 9:10-phenanthroline (phen) or 2,2'bipyridine (bipy) show induced Cotton effects in the aromatic region. The effect is ascribed to interactionsbetween the ...
Synthesis, characterization, and investigation of the thermal behavior of Cu(II) pyrazolyl complexes
This work reports the synthesis, characterization, and thermal behavior of three complexes of copper (II): [CuCl(2)(HPz)(4)] (1), [CuCl(2)(HdmPz)(4)] (2), and [CuCl(2)(HIPz)(4)] (3) (HPz = pyrazole; HdmPz = 3,5-dimethylpyrazole; ...
Chemisorption of Cu-II and Co-II chlorides and beta-diketonates on silica gel functionalized with 3-aminopropyltrimethoxysilane
(Elsevier Science BvAmsterdamHolanda, 2000)
Redox-changes associated with the glutathione-dependent ability of the Cu(II)-GSSG complex to generate superoxide
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 ...
POLI-D-GALACTOSAMINA COMO LIGANTE EN LA FORMACION DE COMPLEJOS CON Cu(II) y Ni(II)
(Sociedad Chilena de Química, 2000)
Síntese e caracterização de complexos de Cu(I), Cu(II) E Au(I) com ligantes triazenidos contendo substituintes triazóis
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2013-11-29)
Triazenido ions are isoelectronic to amidinato anions,[R'N C(R)=NR']- and have a broad versatility in coordination chemistry. Metal complexes including triazenido ligands find applications in various areas of chemistry. ...
