DNA interaction and antimicrobial studies of novel copper (II) complex having ternary Schiff base
A novel ternary Schiff base ligand (HL) of ONO type and its copper (II) complex weresynthesised using 2-aminophenol and o-acetoacetotoluidide. They have been characterised by theusual analytical and spectral methods. The interaction of the complex with calf-thymus (CT)DNA has been investigated by UV-Vis, viscosity measurement, cyclic voltammetry anddifferential pulse voltammetry studies. The re...
متن کاملThe isatin-Schiff base copper(II) complex Cu(isaepy)2 acts as delocalized lipophilic cation, yields widespread mitochondrial oxidative damage and induces AMP-activated protein kinase-dependent apoptosis.
We previously demonstrated that Bis[(2-oxindol-3-ylimino)-2-(2-aminoethyl)pyridine-N,N']copper(II) [Cu(isaepy)(2)] was an efficient inducer of the apoptotic mitochondrial pathway. Here, we deeply dissect the mechanisms underlying the ability of Cu(isaepy)(2) to cause mitochondriotoxicity. In particular, we demonstrate that Cu(isaepy)(2) increases NADH-dependent oxygen consumption of isolated mi...
متن کاملCopper(II) mediated anion dependent formation of Schiff base complexes.
A tetranuclear mixed ligand copper(II) complex of a pyrazole containing Schiff base and a hydroxyhexahydropyrimidylpyrazole and copper(II) and nickel(II) complexes of the Schiff base having N-donor atoms have been investigated. A 2 equiv amount of 5-methyl-3-formylpyrazole (MPA) and 2 equiv of 1,3-diamino-2-propanol (1,3-DAP) on reaction with 1 equiv of copper(II) nitrate produce an unusual tet...
متن کاملCytotoxic and anticancer studies of an oxygen and nitrogen donor novel Schiff base ligand and its copper (II) complex
A selected solid complex of the Schiff base ligand derived from Glutaric anhydride with Cu(II) ion was synthesized and characterized by FT-IR, Electronic, ESR Spectral Analyses, Magnetic susceptibility and Molar Conductance Measurements. The disappearance of ν(O-H) hydroxyl band of the phenolic and the lowering shift of the stretching frequency of the ν(CH=N) azomethine band in the ligand after...
متن کاملPro-apoptotic activity of novel Isatin-Schiff base copper(II) complexes depends on oxidative stress induction and organelle-selective damage.
We characterized the pro-apoptotic activity of two new synthesized isatin-Schiff base copper(II) complexes, obtained from isatin and 1,3-diaminopropane or 2-(2-aminoethyl)pyridine: (Cu(isapn)) and (Cu(isaepy)(2)), respectively. We demonstrated that these compounds trigger apoptosis via the mitochondrial pathway. The early induction of the p53/p21 system indicates a role for p53 in cell death, h...
