Platinum(II) and gold(I) complexes based on 1,1 '-bis(diphenylphosphino)metallocene derivatives: Synthesis, characterization and biological activity of the gold complexes

• The synthesis of series of 1,2,1' substituted bis(diphenylphosphino)- ruthenocenyl (1-4) and ferrocenyl cis-platinum(II) (5-7) and gold(I) (8-12) complexes are described. Crystal structures of 2 and 4, as well as 5, 6 and 10 confirm the molecular geometry of these ligands and their metal complexes. Preliminary investigation of four gold complexes as potential anticancer, antiHIV and antimalaria showed at least one gold compound that has excellent activity towards one of these diseases. The three gold(I) complexes, {1- [1-(dimethylamino)ethyl]-1 ,2-bis(diphenylphosphino)ruthenocene-kappa P-2,P'}bis[chlorogold(I)] (8) (IC50 = 1.40 mu M), {1-[1-(acetoxyethyl)-1',2-bis(diphenylphosphino)ferrocene-kappa P-2,P']bis[chlorogold(1)] (9) (IC50 = 0.51 mu M), {1-[1-(3-carboxypropanamido)ethyl]-1',2-bis(diphenylphosphino)-ruthenocene kappa P-2,P'} bis[chlorogold(I)] (12) (IC50 = 1.784 mu M), have the best activities against cancer, HIV and malaria respectively.
