Platinum coordination complexes are currently one of the most compounds used in the treatment of solid tumors. However, its use is limited by severe side effects such as nephrotoxicity. Our platinum-based drug discovery program is aimed at developing drugs capable of diminishing toxicity and broadening the clinical spectrum of activity of cisplatin. We synthesized new Pt(II) complex analogue containing 1,2-diaminocyclohexane (dach) as carrier ligand and 1,3-bis(diphenyl phosphino)propane (DPPP) as a leaving group. Furthermore, nitrate was added to improve the solubility. A new series of PC-1 [Pt(cis-dach) (DPPP)]. $2NO_3_2$ was synthesized and characterized by their elemental analysis and by various spectroscopic techniques [infrared (IR), $^{13}carbon$ nuclear magnetic resonance (NMR)]. PC-1 was demonstrated acceptable antitumor activity aganist SKOV -3, OVCAR-3 human ovarian adenocarcinomacells and significant activity as compared with that of cisplatin. The toxicity of PC-1 was found quite less than that of cisplatin using MTT, $[^3H]thymidine$ uptake and glucose consumption tests in rabbit proximal tubule cells, human kidney cortical cells and human renal cortical tissues. Based on these results, this novel platinum compound represent a valuable lead in the development of a new anticancer chemotherapeutic agent capable of improving antitumor activity and low toxicity.
