On the interaction of copper( ii ) with disulfiram

open access: yesChem. Commun., 2014
The interaction of copper( ii ) ions with disulfiram, potentially important for new anticancer treatments, is explored under steady-state and kinetic conditions using a multi-spectroscopic approach which could lead to a deeper understanding of the mechanism of the reaction and may have ...

Modeling Cu(II) Binding to Peptides Using the Extensible Systematic Force Field

open access: yesBioinorganic Chemistry and Applications, 2010
The utility of the extensible systematic force field (ESFF) was tested for copper(II) binding to a 34-amino-acid Cu(II) peptide, which includes five histidine residues and is the putative copper-binding site of lysyl oxidase.
