The binding reaction of the Copper(II) Complex [Cu2Cl4(C17H22N2)2]with bovine serum albumin (BSA) was studied by UV absorption spectroscopy under the simulative physiological conditions. The binding constants were 6.67×104, 5.61×104 and 3.79×104 L•mol-1 at 291K, 298 K and 305K respectively. The thermodynamic parameters ?H, ?S and ?G were calculated at different temperatures, and the result showed...
The interaction of rare earth complex [Er(C18H22.5N2O4)2] and bovine serum albumin (BSA) under physiological condition was studied by fluorescence spectrum. The experiment demonstrated that the fluorescence quenching of BSA by Er(III) complex is a result of the formation of ground state complex and the quenching mechanism is mainly static quenching. The corresponding binding constants between Er(III)...
The binding reaction of the N1-(1-phenylethyl) propane-1,2-diamine nickel(II) complex with bovine serum albumin (BSA) was studied by fluorescence spectroscopy under the simulative physiological conditions. The experimental results show that the complex had a quite strong ability to quench the fluorescence from BSA and the quenching mechanism of this complex to bovine serum albumin was static quenching...
The interaction between praseodymium complex [Pr(C18H22.5N2O4)2] and bovine serum albumin (BSA) under physiological condition was investigated by fluorescence spectrum. The quenching mechanism of fluorescence was suggested as static quenching according to the Steru-Volmer equation. The binding constants between Pr(III) complex and BSA were 7.31×104L·mol−1(291K), and the binding sites were 1. The thermodynamic...
