摘要

Of late, cancer has become a terrible disease affecting people throughout the world. Keeping this in mind, we tried to design drugs that are more lipophilic, target-specific, water-soluble, cytoselective and fluorescent. In this regard, we reported novel ruthenium(ii)-p-cymene imidazophenanthroline scaffolds as effective DNA targeting agents. The planarity of imidazophenanthroline ligands caused the Ru(ii) complex to be a good intercalator. An extended pi-electronic conjugation was introduced in the imidazophenanthroline moieties through the Suzuki and Sonogashira coupling reactions. Here, we synthesized nine Ru(ii) complexes (16a-b, 17a-d, and 19a-c). Among these, [(eta(6)-p-cymene)RuCl(K-2-N,N-2-(4 '-methyl-[1,1 '-BIphenyl]-4-yl)-1H-imidazo[4,5-f][1,10]phenanthroline)]center dot PF6 (16b) exhibited the best potency and selectivity with excellent cellular uptake; [(eta(6)-p-cymene)RuCl(K-2-N,N-2-(4-(phenylethynyl)phenyl)-1H-imidazo[4,5-f][1,10]phenanthroline)]center dot PF6 (17a) acted as a cytoselective probe for live cell imaging.
