[Pd(2)L(2)(mu-dppe)Cl(2)] 3, which was characterised in solution by (1)H and (31)P NMR spectroscopy and in the solid state by X-ray crystallography. Complex 3 was tested in vitro against a number of cell lines. For example, it inhibited K562 leukaemia cells with an IC(50) value of 4.3 microM (1 h exposure) and displayed cathepsin B inhibitory action with an IC(50) value of 3 microM.
