Ruthenium(II) mixed-ligand complexes containing 2-(6-methyl-3-chromonyl)imidazo[4,5-f][1,10]-phenanthroline: Synthesis, DNA-binding and photocleavage studies
چکیده انگلیسی

Two novel Ru(II) complexes [Ru(bpy)2(MCMIP)]2+ (1) and [Ru(phen)2(MCMIP)]2+ (2) (bpy = 2,2′-bipyridine; phen = 1,10-phenanthroline; MCMIP = 2-(6-methyl-3-chromonyl)imidazo[4,5-f][1,10]-phenanthroline) have been synthesized and characterized by elemental analysis, mass spectra and 1H NMR. The DNA-binding properties of the complexes were investigated by absorption, emission, melting temperature and viscosity measurements. Experimental results indicate that the two complexes can intercalate into DNA base pairs. Upon irradiation at 365 nm, two Ru(II) complexes were found to promote the cleavage of plasmid pBR 322 DNA from supercoiled form I to nicked form II, and the mechanisms for DNA cleavage by the complexes were also investigated.

Two novel ruthenium(II) complexes [Ru(bpy)2(MCMIP)]2+ (1) and [Ru(phen)2(MCMIP)]2+ (2) have been synthesized and characterized. Their DNA-binding and photocleavage properties have also been investigated by spectroscopic methods, viscosity and electrophoresis measurements.Figure optionsDownload as PowerPoint slide
