Abstract

cis-diamminechloro-[2-(diethylamino)ethyl 4-amino-benzoate, N4]-chlorideplatinum(II) monohydrochloride monohydrate (DPR) is a new platinum-triamine complex containing as ligand the local anesthetic procaine. In this study DPR was compared to the parent compound cisplatin (cis-DDP) in order to study the influence of both molecules on the cell cycle phases, and particularly on the induction of apoptosis. P388 murine leukemic cells were used as cellular model, and were exposed in vitro to either compound, continuously for 24 hours. At the end of the incubation, the thymidine uptake, the trypan blue dye exclusion assay, and the flow cytometry were assessed. Both the cytotoxic activity and the inhibition of DNA synthesis evaluated after 24 h incubation with DPR or cis-DDP were comparable. Moreover, cell cycle was modified in a comparable manner by both molecules. In particular the induction of the apoptotic effect was similarly induced by the same concentrations of the compounds and time exposure. In conclusion, DPR and cis-DDP seem to have a similar effect on the cell cycle of P388 leukemic cells and particularly on the induction of the programmed cell death.
