Abstract:
:A series of platinum(II) complexes of N-monoalkyl-1R,2R-diaminocylclohexanes with 3-(nitrooxy)cyclobutane-1,1-dicarboxylate as a leaving group were synthesized and characterized by elemental analysis, IR, (1)H, (13)C and (195)Pt NMR spectroscopy together with ESI-MS spectrometer. In vitro cytotoxicity study on these complexes indicated they have considerable cytotoxicity against the tested cancer cell lines. Notably, complexes 2, 4, 6 and 8 showed high cytotoxicity against human A549 and HCT-116 cancer cell lines. The DNA binding of the platinum-based complexes 1 and 3-5 studied by agarose gel electrophoresis was in accordance with cytotoxicity to some extent. Reactions between the corresponding aqua analogues of the resulting complexes and glutathione (GSH) were studied by kinetics method under pseudo-first-order conditions using UV-Vis spectrophotometric technique. The results indicated that the introduction of alkyl moieties in 1R,2R-diaminocyclohexane (1R,2R-DACH) decreased the reaction rates of the aqua analogues of complexes 3-5 and GSH under the tested condition. Moreover, the stability of complex 8 was investigated by HPLC-MS technique at different time in 36 h.
