that these complexes exhibited anticancer activity against various cancer cell lines. Ruthenium(II) complexes were confirmed to preferentially accumulate in the nucleus of cancer cells and induced DNA damage. Flow cytometric analysis and AO/EB staining assays indicated that these complexes induced cell apoptosis. With the loss of the mitochondrial membrane potential, the Ru(II) complexes induce apoptosis
五种新型钌(II)配合物[Ru(dtzp)(dppt)] 2+(1),[Ru(dtzp)(pti)] 2+(2),[Ru(dtzp)(ptn)] 2+(3),[Ru(dtzp)(pta)] 2+(4)和[Ru(dtzp)(ptp)] 2+(5)(其中dtzp = 2,6-二(噻唑-2-基)吡啶, dppt = 3-(1,10-菲咯啉-2-基)-5,6-二苯基-三嗪),pti = 3-(1,10-菲咯啉-2-基)-三嗪-[5, 6- f ] isatin,ptn = 3-(1,10-菲咯啉-2-基)-三嗪[5,6- f ]萘,pta = 3-(1,10-菲咯啉-2-基)-三嗪[5,6- f合成并表征了pta = 3-(1,10-菲咯啉-2-基)-三嗪[ 5,6 - f ]-菲)。配合物3-5的结构是通过X射线衍射确定的。通过光谱和粘度测量研究了复合物的DNA结合行为。结果表明,除配合物1外,
