Complexes of the type [PdX2(tdmPz)] {X = Cl-(1) Br-(2); l(-)(3); SCN-(4); tdmPz = 1-thiocarbamoy1-3,5-dimethylpyrazole} have been synthesized and characterized. Compound 1 was formed from the reaction between [PdCl2(CH3CN)(2)] and 1-thiocarbamoy1-3,5-dimethylpyrazole. Complexes 2, 3 and 4 were obtained by metathesis of the chloro groups from 1 by bromide, iodide and thiocyanate ions, respectively. All the compounds and cisplatin have been tested in vitro by WIT assay for their cytotoxicity against three murine cancer cell lines: mammary adenocarcinoma (LM3 and LMM3) and lung adenocarcinoma (LP07) as well towards normal murine peritoneal exudate cells (PEC). Promising cytotoxic effect against LM3 has been found for 3 showing IC50 equal to 24.5 mu M which is comparable to the value obtained for cisplatin (30.3 mu M). (C) 2010 Elsevier Masson SAS.
