The [tris(pyrazolyl)methane]ruthenium complexes [(K3-tpm) RuCl(solv)2]PF6 [tpm = tris(pyrazolyl)methane; solv = MeCN, dmso] and [(K3-tpm)RuCl(LL)]PF6 [LL = K 2-dppe, K2-dppp, K2-dppb, (PMePh 2)2] have been prepared, characterized and screened in vitro for their antiproliferative properties against the MCF-7 (breast) and HeLa (cervical) cancer cell lines by using the MTT assay. Although the MeCN and dmso complexes showed no activity under the conditions used, the phosphane complexes exhibited remarkable cytotoxic behaviour.
