Sodium bis[N-2-oxyphenyl-5-substituted-salicylideneiminato-ONO]ruthenate(Ⅲ) hemitriethylamine compounds of general formula Na[Ru(N-R-5-X-salim)2]'0.5Et3N, where, R = C6H40, X = El, Br, NO2, salim = salicylidenei...Sodium bis[N-2-oxyphenyl-5-substituted-salicylideneiminato-ONO]ruthenate(Ⅲ) hemitriethylamine compounds of general formula Na[Ru(N-R-5-X-salim)2]'0.5Et3N, where, R = C6H40, X = El, Br, NO2, salim = salicylideneiminato, Et3N triethylamine, were synthesized and characterized on the basis of elemental analysis, MALDI-TOF (matrix-assisted laser desorption/ionization/time-of-flight) mass spectra, IH NMR (nuclear magnetic resonance), electronic spectra and cyclic voltammograms. Ru(Ⅲ) is chelated with two O2N anionic tridentate Schiff bases derived from 5-X-salicyladehyde and 2-aminophenol. Spectroscopic titrations of the Ru(Ⅲ) compounds with CT DNA (calf thymus DNA) in the LMCT (ligand metal charge transfer) region have shown moderate intercalation properties of compounds with binding constants KD = 2.06-3.85 × 104 Ml. Electrochemical evidence of intercalative mode of binding is based on the decrease of current and shift of anodic and cathodic peaks towards higher values of potential with IxL-increment of CT DNA in Ru(Ⅲ) compound solution.展开更多

The structures of the synthesized compounds were determined on the basis of their FTIR, UV (ultraviolet), elemental analysis and H-NMR (H-nuclear magnetic resonance) spectral date. The purity of synthesized compounds was checked by performing TLC (thin layer chromatography). The antibacterial activity was evaluated in DMSO (dimethyl sulfoxide).展开更多
