摘　　要：Seven novel platinum （Ⅱ） complexes [ Pt（Ⅱ） （NH3） （CH3NH2）X2] （Ⅰ-Ⅶ ） （ X： CH3COO^-, CH2CICOO^- , CHCI2COO^- , C6H5-COO^- , p-CH3O--C6H4-COO^- , p-NH2-C6H4-COO^- , p-NO2--C6H4- COO^-） were prepared and characterized by means of elemental analysis, molar conductivity, thermal analysis, IR, UV, and ^1H 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 --Ⅻ） display substantially greater activities agaist 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.Seven novel platinum （Ⅱ） complexes [ Pt（Ⅱ） （NH3） （CH3NH2）X2] （Ⅰ-Ⅶ ） （ X： CH3COO^-, CH2CICOO^- , CHCI2COO^- , C6H5-COO^- , p-CH3O--C6H4-COO^- , p-NH2-C6H4-COO^- , p-NO2--C6H4- COO^-） were prepared and characterized by means of elemental analysis, molar conductivity, thermal analysis, IR, UV, and ^1H NMR spectrometries.
