A library of 32 organoruthenium compounds has been synthesised. Known and novel C–N cyclometalated compounds as well as N–C–N and N–N–C pincer derivatives of this metal have been used in this purpose. Most of the compounds have been tested for their in vitro antitumoral behaviours, good to excellent activities have thus been found. Several of the newly synthesized compounds pass the symbolic barrier of the nanomolar range for their IC50 indicating a critical improvement. The level of activity is tentatively correlated to physicochemical properties of the compounds such as their RuIII/II redox potential and their lipophilicity (log P).
