Computer simulation of nickel in blood-plasma following the in vitro investigations of complex formation chemistry with polyamine(amide) ligands

Abstract: In- and out-of-cell potentiometric techniques have been used to determine the formation constants for nickel(II) with 3,3,9,9-tetramethyl-4,8-diazaundecane-2,10-dione dioxime (L(1)), N,N[prime or minute]-bis(2-hydroxyiminopropionyl)propane-1,3-diamine (L(2)) and 1,15-bis(N,N-dimethyl)-5,11-dioxo-8-(N-benzyl)-1,4,8,12,15-pentaazapentadecane (L(3)) at 25 degrees C and an ionic strength of 0.15 mol dm(-3). Nickel(II) forms stable complexes with L(1) and L(2) where square-planar [NiLH(-1)] and [NiLH(-2)] species p… Show more

“…7 In soil solutions, free Ni 2+ concentrations, together with pH and [Ca 2+ ], 8 have been shown to be key measurements required for evaluating nickel toxicity in plants. Indeed, trace element speciation analysis is important to understand the impact of toxic metal in biological fluids, 9,10 and to control correctly the administration of metal-based drugs or the use of radionuclide imaging agents.…”
