• PubMed Abstract: 
  

The binding properties of AziRu, a ruthenium(III) complex with high antiproliferative activity, toward a hen egg white lysozyme have been investigated by X-ray crystallography and Raman microscopy. The data provide clear evidence on the mechanism of AziRu-protein adduct formation and of ligand exchange in the crystal state.
