Four-component relativistic P NMR calculations for trans-platinum(ii) complexes: importance of the solvent and dynamics in spectral simulations.

We report a combined experimental-theoretical study on the 31P NMR chemical shift for a number of trans-platinum(ii) complexes. Validity and reliability of the 31P NMR chemical shift calculations are examined by comparing with the experimental data. A successful computational protocol for the accurate prediction of the 31P NMR chemical shifts was established for trans-[PtCl2(dma)PPh3] (dma = dimethylamine) complexes.

The second generation of iodido complexes: trans-[PtI2(amine)(amine')] bearing different aliphatic amines.

The antitumoral potential for a series of platinum iodido complexes, all bearing the same aliphatic amines (first iodido complexes generation), was demonstrated in a previous study. Concretely, cis complexes were shown to have a peculiar and different reactivity compared to cisplatin with sulfur donors models and Cyt C. In this work we have synthesized and studied iodido complexes bearing different aliphatic amines in trans configuration (the second generation) to investigate their potential antitumor activity in a panel of cell lines.

Oxidation of anticancer Pt(II) complexes with monodentate phosphane ligands: towards stable but active Pt(IV) prodrugs.

The synthesis, characterization and cytotoxicity studies of two novel platinum(IV) complexes, trans-PtCl4(dma)(PPh3), 1, and trans-PtCl4(ipa)(PPh3), 2, where dma is dimethylamine and ipa is isopropylamine, have been carried out. Both complexes contain aliphatic amines trans to phosphane ligands as a good alternative to take advantage of the phosphane group lipophilicity and the stability of platinum(IV) to obtain more effective drugs. Moreover, the complexes are stable in solution and such stability allowed their antitumoral action and DNA interaction to be checked and proved.
