Seven novel platinum (Ⅱ) complexes [Pt (Ⅱ) (NH3) (CH3NH2) X2] (Ⅰ -Ⅶ) (X: CH3COO- ,CH2 ClCOO - , CHCl2COO -, C6H5-COO - , p-CH3O-C6H4 -COO - , p-NH2-C6 H4 -COO - , p-NO2 -C6 H4 -COO-) were prepared and characterized by means of elemental analysis, molar conductivity, thermal analysis,IR, UV, and 1 H NMR spectrometries. The cytotoxicity against HCT-8, BGC-823, MCF-7, EJ, and HL-60 cell lines increases in the following sequence: cisplatin ＞Ⅳ＞Ⅴ＞Ⅵ＞Ⅶ＞Ⅰ＞Ⅱ＞Ⅲ. Moreover, the complexes(Ⅰ -Ⅶ) display substantially greater activities against EJ and HL-60 cell lines than those against the cell lines from other carcinomas. They can induce a concentration-dependent accumulation of HL-60 cells in the G2/M phase of the cell cycle as cisplatin. There is no significant correlation between total DNA platination levels and cytotoxicity of the complexes.
