Biologically vital metal-based antimicrobial active mixed ligand complexes: synthesis, characterization, DNA binding and cleavage studies
Few novel cobalt(II) and copper(II) complexes [M(fmp)3]Cl2, [M(fmp)(bpy)2]Cl2,[M(fmp)(phen)2]Cl2 and [M(fmp)(phen)(bpy)]Cl2 (fmp = 3-furan-2-ylmethylene-pentane-2,4-dione, phen = 1,10-phenanthroline, bpy = 2,2'-bipyridine) have been synthesized andcharacterized by elemental analyses, molar conductance, magnetic susceptibility measurements,IR, electronic, EPR, mass spectra and cyclic voltammetri...
متن کاملPhotoinduced ligand isomerisation in a pyrazine-containing ruthenium polypyridyl complex.
Photochemically-induced ligand rearrangements for the N2 and N4 coordination isomers of the complex [Ru(bpy)(2)(Hpztr)](2+) and its deprotonated analogue [Ru(bpy)(2)(pztr)](+), where bpy is 2,2'-bipyridyl and Hpztr is pyrazine-1,2,4-triazole ligand, are reported. (1)H NMR spectroscopic and HPLC studies indicate that in acetone and acetonitrile the complexes are photostable when the triazole rin...

متن کاملPhotoinduced electron transfer between ruthenium complexes and nucleotides or DNA
The quenching of the luminescence of Ru(TAP)++, Ru(HAT)z(bpyp+ (TAP = 1,4,5$-tetraazaphenanthrene; HAT = 1,4,5,8,9,12-hexaazatphenylene; bpy = 2,2'bipyridyl) and related oxidising complexes by DNA, polynucleotides, and purine nucleotides occurs by reductive electron transfer. Laser flash photolysis provides evidence for the formation of the reduced metal complex and the deprotonated nucleotide ...
متن کاملLigand substitutions between ruthenium–cymene compounds can control protein versus DNA targeting and anticancer activity
Ruthenium compounds have become promising alternatives to platinum drugs by displaying specific activities against different cancers and favourable toxicity and clearance properties. Nonetheless, their molecular targeting and mechanism of action are poorly understood. Here we study two prototypical ruthenium-arene agents-the cytotoxic antiprimary tumour compound [(η(6)-p-cymene)Ru(ethylene-diam...
