Activity of some platinum(II/IV) complexes with O,O-n-butyl-and O,O-n-pentyl-ethylenediamine-N,N '-di-3-propanoate and halogeno ligands against HeLa and K562 cell lines and human PBMC

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-ii-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)Cl-2], respectively. The complexes were characterized by elemental analysis, infrared, H-1 and C-13 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 bloo...d mononuclear PBMC cells.
