    Abstract:
    The cisplatin analogoues platinum (II) complexes of the general formula cis-[PtL2Cl2], where L is monodentate diethyl 2-, 3- or 4-pyridylmethylphosphonate (2-, 3- or 4-pmpe) ligand, have been synthesized and characterized by means of IR and NMR (1H, 31P, 195Pt) spectroscopy. The crystal and molecular structure of cis-[Pt(4-pmpe)2 Cl2].H2O (A3) shows a square planar geometry of PtL2Cl2, with two organic molecules and two chloride leaving ligands in a cis configuration. The antitumor activity of the platinum (II) complexes was examined against Sarcoma Sa-180 in mice. The obtained results indicate a marked anticancer effect of platinum phosphonate complexes, and moderate nephrotoxicity evaluated in the BUN and creatinine levels in comparison with cisplatin (CDDP).
