Abstract

A new palladium(II)-dithiocarbamate complex, [Pd(ESDT)Cl](n), was synthesised and its chemical characteristics are discussed. This complex was examined for its cytotoxic properties in human tumour cell lines; for comparison, the cytotoxicity of cisplatin was evaluated under the same experimental conditions. In particular, Pd(II)-complex cytotoxicity on ovarian carcinoma C13 cells, resistant to cisplatin, showed that there seemed to be no cross-resistance between [Pd (ESDT)Cl](n) and cisplatin. The effects on the kidney were also studied. Biochemical investigation on urinary parameters showed that the effects after a single injection are similar to those of cisplatin, with an increase of urinary proteins and enzyme excretion in urine, and a significant decrease of glutamine synthetase activity in the renal tissue. In addition, the Pd(II)-complex caused a significant decrease of p-aminohippuric acid uptake in renal cortical slices relative to cisplatin. On the other hand, histopathological findings showed that the effects of the Pd(II)-complex are more severe and diffuse than the damage caused by cisplatin. Biochemical and histopathological findings show that the Pd(II)-complex affects the pars recta and pars convoluta, in contrast to cisplatin, which only affects the pars recta
