Heteroleptic palladium(II) complexes of the type formula [(DTC)(Pd)(PR3)Cl], where DTC = bis(2-ethylhexyl)dithiocarbamate (1, 8, 9, 10), bis(2-methoxyethyl)dithiocarbamate (2), di-n-decyldithiocarbamate (3, 6), di-n-hexyldithiocarbamate (4, 7), bis(2-methylbutyl)dithiocarbamte (5); PR3 = diphenyl-t-butylphosphine (1), diphenyl-n-propylphosphine (2), triphenylphosphine (3, 4, 5, 10), diphenyl-p-tolylphosphine (6, 7, 8), diphenylbenzylphosphine (9); have been synthesized and characterized by FTIR, Raman, multinuclear and multinuclear NMR (1H, 13C, 31P) spectroscopy and elemental analyses. The structures of complexes (1 and 2) were determined by single-crystal X-ray diffraction. The geometries around the metal centers are pseudo square-planar. The new complexes exhibit moderate anticancer and antibacterial activity.

Mixed-ligand palladium(II) complexes of the type [(DT)Pd(PR 3)Cl], where DT = diethyldithiocarbamate (1), dibutyldithiocarbamate (2,3), dipropyldithiocarbamate (4,5), bis(2-methoxyethyl)dithiocarbamate; PR3 = benzyldiphenylphosphine (1,4), diphenyl-o-tolylphosphine (2), diphenyl-t-butylphosphine (3), P-chlorodiphenylphosphine (5) and triphenylphosphine (6), have been synthesized and characterized by elemental analyses and FT-IR, Raman and multinuclear NMR spectroscopy. The structures of compounds 1 and 2 were determined by single-crystal X-ray diffraction (XRD) measurements and these analyses showed that the complexes have pseudo square-planar geometry around the Pd(II) and that the dithiocarbamate ligand is bound in a bidentate fashion, while the remaining two positions are occupied by a tertiary organophosphine and a chloride ligand. The anticancer studies showed that the Pd(II) complexes are highly active against cisplatin-resistant DU145 human prostate carcinoma (HTB-81) cells with the highest activity shown by compound 6 (IC50 = 2.12 μm). The redox behavior and ds-DNA-denaturing ability of the complexes were studied by cyclic voltammetry and two reduction and one oxidation waves were observed. The decrease in the reduction peak currents illustrated the consumption of the mixed-ligand drug by the DNA molecule. Copyright
