Synthesis, structure and SOD-like activity of a ternary Cu(II) complex with 1,10-phenanthroline andL-valinate

Synthesis, nucleic acid binding and cytotoxicity of polyethyleneimine-copper(II) complexes containing 1,10-phenanthroline and l-valine

“…In the UVeVisible region, the intense absorption bands appear from 200 to 350 nm is attributed to intra ligand transitions. The other absorption band which appears around 640 nm is assigned to ded transition [35]. The electron magnetic resonance spectra (ESR) of Cu II complex with a g iso ¼ 2.079 confirms the square-pyramidal geometry [36].…”

“…All the experiments involving the interaction of the polymerecopper(II) complex with nucleic acids were carried out with twice distilled water in buffer containing 5 mM TriseHCl/50 mM NaCl at pH 7.0. The complex, [Cu(phen)(L-Val) H 2 O]Cl$H 2 O, was prepared as reported earlier [35]. Jurkat, a T cell lymphoma cell line and Raji, a B Cell lymphoma cell lines were obtained from National Centre for Cell Sciences (NCCS) Pune, India.…”

Synthesis, Structure, DNA Interaction, and SOD Activity of Three Nickel(II) Complexes Containing L-Phenylalanine Schiff Base and 1,10-Phenanthroline

“…Figure 9 shows that, with the increase of the concentration of the complex, the slope of the line gradually decreased, indicating that the greater the concentration, the greater the inhibition rate. The inhibitory rate ( η ) of the complex to O 2 ·− can be determined by the following formula [ 47 ]: where k is the slope of the straight line without complex and k ′ is the slope of the straight line after adding the complex. The 50% of activity (IC 50 ) indicates the molar concentration of the tested complex which caused a 50% scavenging effect on superoxide radicals.…”

Ternary copper(II) complexes of levofloxacin and phenanthroline derivatives: In-vitro antibacterial, DNA interactions, and SOD-like activity

“…All measurements were carried out at room temperature. The % inhibition (η) of NBT reduction was calculated using following equation 21 :…”
