Coordination abilities of N-terminal fragments of alpha-synuclein towards copper(II) ions: a combined potentiometric and spectroscopic study.
The results suggest the formation of 2N, 3N, 4N complexes (in equatorial plane) and the involvement of the lateral NH(2) group of Lys residue in the axial coordination of Cu(II) ion. Expand
High-field EPR and magnetic susceptibility studies on binuclear and tetranuclear copper trifluoroacetate complexes. X-ray structure determination of three tetranuclear quinoline adducts of copper(II)
High-field EPR spectra allowed determination of the spin Hamiltonian parameters for the spin quintet state (S = 2) in the ferromagnetic complexes, which facilitated accurate interpretation of their magnetic susceptibility data. Expand
Dinuclear metallacycles with single M-O(H)-M bridges [M = Fe(II), Co(II), Ni(II), Cu(II)]: effects of large bridging angles on structure and antiferromagnetic superexchange interactions.
The reactions of M(ClO4)2·xH2O and the ditopic ligands m-bis[bis(1-pyrazolyl)methyl]benzene (Lm) or m-bis[bis(3,5-dimethyl-1-pyrazolyl)methyl]benzene (Lm*) in the presence of triethylamine lead toExpand
Mixed-ligand copper(II) complexes with diethylenetriamine and histidine- or methioninehydroxamic acids in water solution
Abstract Stability of the mixed-ligand complexes of Cu2+ ion with diethylenetriamine [bis(2-aminoethyl)amine, dien] as a primary ligand and histidinehydroxamic acidExpand
Copper(II) complexes with substituted imidazole and chlorido ligands: X-ray, UV–Vis, magnetic and EPR studies and chemotherapeutic potential
Abstract Crystal structures, UV–Vis and EPR spectra and magnetic properties of four copper(II) complexes with chloride anions and alkyl derivatives of imidazole: 4-methylimidazole, 2-ethylimidazole,Expand
Can Carbamates Undergo Radical Oxidation in the Soil Environment? A Case Study on Carbaryl and Carbofuran.
The findings of this study suggest that the radicals present in soil can play an important role in natural remediation mechanisms of carbamates. Expand
Molecularly imprinted polymeric Cu(II) catalysts with modified active centres mimicking oxidation enzymes
In this paper the preparation of surface molecularly imprinted Cu(II) catalysts with modified active centres is described. The resins were synthesized using suspension polymerization ofExpand
Anion exchangers with alkyl substituted guanidyl groups ☆: Gold sorption and Cu(II) coordination
Abstract Two methods of introducing guanidyl groups into polymer matrix were investigated in this work: the reaction of cyanamide (alkyl substituted cyanamides) and carbodiimides with amino groups inExpand
Comparison of 1-hydroxymethyl-3,5-dimethylpyrazole and 1-benzyl-2-hydroxymethylimidazole coordination properties towards copper(II)
Abstract Using 1-hydroxymethyl-3,5-dimethylpyrazole as the starting ligand and 2-propanol as the solvent and a molar ratio Cu:L, 1:4, a dinuclear Cu(II) complex has been obtained. The microanalyticalExpand
An EPR study of polysaccharide copper(II) complexes in composite dextran/epichlorohydrin gels
SummaryThe EPR spectra of composite dextran and carboxymethyldextran gels were studied in order to identify the functional groups involved in copper(II) complexation depending on pH. The porousExpand
