This paper reports on syntheses and characterization of chlorotribromo(O,O-n-butyl-ethylenediamine-N,N′-di-3-propanoate)platinum(IV) [II], dichlorodiiodo(O,O-n-butyl-ethylenediamine-N,N′-di-3-propanoate)platinum(IV) [III], and dichloro(O,O-n-butyl-ethylenediamine-N,N′-di-3-propanoate)platinum(II) [V] complexes, with the formulae [Pt(dbeddp)Br3Cl], [Pt(dbeddp)Cl2I2] and [Pt(dbeddp)Cl2], respectively. The complexes were characterized by elemental analysis, infrared, 1H and 13C NMR spectroscopy and electrospray mass spectrometry. In the aim to assess the selectivity in the antitumor action of these complexes, as well, as tetrachloro(O,O-n-butyl-ethylenediamine-N,N′-di-3-propanoate)platinum(IV) [I] and tetrachloro(O,O-n-pentyl-ethylenediamine-N,N′-di-3-propanoate)platinum(IV) [IV], the antiproliferative action of these compounds was determined to human adenocarcinoma HeLa cells, to human myelogenous leukemia K562 cells and to normal immunocompetent cells, i.e., on human peripheral blood mononuclear PBMC cells.
