چکیده

Two novel coordination compounds of half-sandwiched ruthenium(II) containing 2-(5-fluorouracil)-yl-N-(pyridyl)-acetamide were synthesized, and their intercalation binding modes with calf thymus DNA were revealed by hyperchromism of ultraviolet-visible spectroscopy; the binding constants were determined according to a Langmuir adsorption equation that was deduced on the base of careful cyclic voltammetry measurements. The two compounds exhibited DNA intercalation binding activities with the binding constants of 1.13×106 M-1 and 5.35 ×105 M-1, respectively.

Initial DNA Interactions of the Binuclear Threading Intercalator Λ,Λ-[μbidppz(bipy)4Ru2]4+: An NMR Study with [d(CGCGAATTCGCG)]2**

Binuclear polypyridine ruthenium compounds have been shown to slowly intercalate into DNA, following a fast initial binding on the DNA surface. For these compounds, intercalation requires threading of a bulky substituent, containing one Ru(II), through the DNA base-pair stack, and the accompanying DNA duplex distortions are much more severe than with intercalation of mononuclear compounds. Stru...

Oxidative damage by ruthenium complexes containing the dipyridophenazine ligand or its derivatives: a focus on intercalation.

Interactions with DNA by a family of ruthenium(II) complexes bearing the dppz (dppz = dipyridophenazine) ligand or its derivatives have been examined. The complexes include Ru(bpy)(2)(dppx)(2+) (dppx = 7,8-dimethyldipyridophenazine), Ru(bpy)(2)(dpq)(2+) (dpq = dipyridoquinoxaline), and Ru(bpy)(2)(dpqC)(2+) (dpqC = dipyrido-6,7,8,9-tetrahydrophenazine). Their ground and excited state oxidation/r...

Quinolone antibacterials are one of the most important classes of pharmacological agents known as potent inhibitors of bacterial DNA gyrase and topoisomerase IV that efficiently inhibit DNA replication and transcription by generating several double-stranded DNA break. Some quinolone derivatives demonstrated inhibitory potential against eukaryote topoismarase II and substantial dose-dependent cy...
