Reactivity of the [Au(C^N^C)Cl] complex in the presence of H₂O and N-, S- and Se-containing nucleophiles: a DFT study

G. Y. Sánchez Delgado, D. Paschoal, H. F. Santos

JBIC Journal of Biological Inorganic Chemistry > 2018 > 23 > 8 > 1283-1293

Gold complexes are promising compounds used in cancer chemotherapy. Besides their steric features, which enable biomolecule interactions, the redox instability and the high affinity of gold with cellular nucleophiles influence the biological action in these complexes. Both features were herein theoretically investigated for the [Au(C^N^C)Cl] probe complex (C^N^C = 2,6-diphenylpyridine) using H₂O,...
