title: Synthesis, characterization, cytotoxicity and DNA binding studies of diamminediethyldithiocarbamato-platinum(II) nitrate.
abstract: A new complex [Pt(NH3)2(ddtc)]NO3.2H2O as a 1:1 electrolyte has been prepared. This was characterized by spectroscopic methods. The electronic absorption spectrum of this complex in water suggests that it has a square planar geometry. The infrared, 1H NMR and x-ray photoelectron spectroscopic studies suggest the bonding of ammonia molecules and diethyldithiocarbamate as bidentate ligand to platinum(II) in this complex. The 50% inhibition value of this complex against P388 lymphocytic leukemia cells is comparable with cisplatin. This complex interacts with calf thymus DNA by coordinate covalent bond.
