title: Synthesis, characterization, and antitumor activity of a series of novel cisplatin analogs with cis-1,4-diaminocyclohexane as nonleaving amine group.
abstract: A series of novel platinum(II) complexes of the type PtII(cis-1,4-DACH)X (where cis-1,4-DACH = cis-1,4-diaminocyclohexane and X = dichloro, sulfato, oxalato, malonato, methylmalonato, tartronato, or 1,1-cyclobutanedicarboxylato [CBDCA) ligand and novel platinum(IV) complexes of the types PtIV(cis-1,4-DACH)trans(Y)2Cl2 (where Y = chloro, hydroxo, acetato, propionato, or butyrato ligand) and PtIV(cis-1,4-DACH)trans(Cl)2(X) (where X = oxalato or CBDCA ligand) were synthesized and characterized by elemental analysis, infrared, and 195Pt NMR spectroscopic techniques. Platinum complexes had good in vitro cytotoxic activity against murine leukemia L1210/0 (IC50 = 0.0032-1.60 microM) and human ovarian A2780 (IC50 = 0.045-0.430 microM) cell lines.
