Novel platinum(IV) complexes were synthesised to examine the facile modulation of the lipophilicity of the complex by incorporating axial ligands of increasing length, ranging from 2–6 carbons. RP-HPLC was used to establish the lipophilicity of each complex. The in vitro cytotoxicities of all complexes were determined against a panel of malignant cell lines and a non-cancerous cell line. While there

of some [PtA2(GMP)2]2− complexes (A = NH3, or A2 - ethylenediamine, 1,3-propylenediamine R,R-, S,S- and meso-1,2-diaminocyclohexane and R,R-, S,S- and meso-2,3-diaminobutane; GMP = N(7)-coordinated guanosine-5′-monophosphate) have been investigated by means of circular dichroism (CD) spectroscopy. There is only one 1H NMR detectable isomer for the majority of the complexes, whose CD spectra suggest
acid (OA) or OA-nitric oxide (NO) donor derivative coordinating to platinum(II) complexes were designed and synthesized. As expected, complexes 1c and 1d showed selective cytotoxicity to hepatoma carcinoma cells (e.g. HepG2, SMMC-7721, BEL-7402 cells) rather than other tumorcells. Interestingly, they had only a weak toxicity to normal hepatic cells (e.g. LO2 cells). Mechanism studies revealed that

Six platinum(II) complexes of the type [Pt(PL)(AL)]2 +, where PL is a bidentate pyridyl-1,2,3-triazole “click” ligand and AL is the R,R or S,S isomer of 1.2-diaminocyclohexane, have been synthesised and characterised by several methods including elemental microanalysis, proton NMR spectroscopy and X-ray crystallography. The in vitro cytotoxicity of each complex was assessed in eleven cell lines, revealing
