Platinum amidine complexes represent a new class of potential antitumor drugs that contain the imino moiety HN[DOUBLE BOND]C(sp2) bonded to the platinum center. They can be related to the iminoether derivatives, which were recently shown to be the first PtII compounds with a trans configuration endowed with anticancer activity. The chemical and biological properties of platinum amidine complexes, and more generally of platinum imino derivatives, can be rationally modified through suitable synthetic procedures with the aim of improving their cytotoxicity and antitumor activity. The addition of protic nucleophiles to nitriles coordinated to platinum in various oxidation states can offer a wide variety of complexes with chemical, structural, and physical properties specifically tuned for a more efficacious biological response.

Abstract
Platinum amidine complexes represent a new class of potential antitumor drugs that contain the imino moiety HN[DOUBLE BOND]C(sp2) bonded to the platinum center. They can be related to the iminoether derivatives, which were recently shown to be the first PtII compounds with a trans configuration endowed with anticancer activity. The chemical and biological properties of platinum amidine complexes, and more generally of platinum imino derivatives, can be rationally modified through suitable synthetic procedures with the aim of improving their cytotoxicity and antitumor activity. The addition of protic nucleophiles to nitriles coordinated to platinum in various oxidation states can offer a wide variety of complexes with chemical, structural, and physical properties specifically tuned for a more efficacious biological response.Pubblicazioni consigliate
