Abstract
Pt-based drugs are widely used in clinics for the treatment of cancer. The mechanism of action
of these molecules relies on their interaction with DNA. However, the recognition of these metal compounds
by proteins plays an important role in defining pharmacokinetics, side effects and their overall
pharmacological profiles. Single crystal X-ray diffraction studies provided important information on the
molecular mechanisms at the basis of this process. Here, the molecular structures of representative adducts
obtained upon reaction with proteins of selected Pt-based drugs, including cisplatin, carboplatin and
oxaliplatin, are briefly described and comparatively examined. Data indicate that metal ligands play a
significant role in driving the reaction of Pt compounds with proteins; non-covalent interactions that occur
in the early steps of Pt compound/protein recognition process play a crucial role in defining the structure
of the final Pt-protein adduct. In the metallated protein structures, Pt centers coordinate few protein
side chains, such as His, Met, Cys, Asp, Glu and Lys residues upon releasing labile ligands.
