title: Cytotoxic activity of platinum(II) and palladium(II) complexes of N-3-pyridinylmethanesulfonamide: the influence of electroporation.
abstract: The series of complexes: cis-[Pd(PMSA)2X2], cis-[Pt(PMSA)2X2], trans-[Pt(PMSA)2I2] and [Pt(PMSA)4]Cl2 (PMSA = N-3-pyridinylmethanesulfonamide; X = Cl, Br, I), previously synthesized and characterized by us, as well as the free ligand PMSA, were tested for their cytotoxic activity without electroporation -- against murine leukemia F4N and human SKW-3 and MDA-MB-231 tumour cell lines -- and with electroporation -- against the latter two cell lines. The majority of the complexes exhibited cytotoxic effects (IC50 < 100 micromol/l) under the conditions of electroporation. Both cis- and trans-[Pt(PMSA)2I2] had pronounced cytotoxic effects (29-61 micromol/l against MDA-MB-231 cells).
