DNA interaction and cytotoxicity studies of new ruthenium(II) cyclopentadienyl derivative complexes containing heteroaromatic ligands

New cyclopentadienyl ruthenium(II) complexes with heteroaromatic ligands were prepared and characterized. Their crystal structures were determined by X-ray diffraction. IC50 values for the compounds against HL-60 cell line are in the range of submicromolar amounts.
