Complexation studies of 5,5'-dinitro BAPTA and Mag-quin-1, with the divalent cations of cadmium, lead, zinc, copper, nickel, and calcium.
(1999)Log values for the first three stepwise, mixed-mode protonation constants of MQ1 are: log KH1 = 7.57 +/- 0.01, log KH2 = 3.73 +/- 0.01, and KH3 = 2.41 +/- 0.02 at I = 0.05 (TEAP). Log values for the 1:1 metal to MQ1 complex ... -
Structural, protonation, and complexation studies of ionophores A23187, 4-ClA23187, and 23,24-Br(2)A23187.
(2006)A23187 is a carboxylic acid polyether ionophore best known for transporting calcium through membranes. However, it has been shown that it transports Zn 2+, Cd2+, and Mn2+ more selectively than Ca2+. Derivatives of A23187 ... -
Studies of the complexation reactions of polyether ionophore antibiotics monensin A and lasalocid A with lead(II), zinc, calcium and sodium cations.
(2000)Lead-ionophore complexes of the form PbLX and PbL2 (L = monensin A or lasalocid A; X- = anion) were isolated and characterized by elemental analysis (X = Cl--) and ESI-MS (X = Cl --, NO3, CH3COO--). Changes in the UV-Vis ... -
Studies of the complexation reactions of polyether ionophore antibiotics nigericin and salinomycin with lead(II), zinc, calcium, magnesium, sodium and potassium cations.
(2005)CD studies in 80% methanol-water indicate that Pb2+ forms 1:1 complexes almost quantitatively with monensin, nigericin, narasin, maduramicin, and salinomycin. UV-Vis titrations in 80% methanol-water showed the same result ...
