| 英文摘要 | The interaction of HE-Eu(III) complex (HE = hematoxylin) with Herring-sperm DNA (hsDNA) has been studied by absorption spectra, fluorescence, and viscosity measurements in physiological buffer (pH = 7.40). The binding constant of HE-Eu(III) complex to hsDNA was obtained by double reciprocal method at 298 and 310K and the corresponding thermodynamic parameters (Delta(r)Hm(circle minus) = 8.55 x 10(4) J mol(-1), Delta(r)Gm(circle minus) = -3.01 x 10(4) J mol(-1), Delta Sm-r(circle minus) = 387.95 J mol(-1) K-1) were calculated, showing that the interaction between HE-Eu(III) complex and hsDNA was driven mainly by entropy. The value of K indicated that the binding mode of HE-Eu(III) complex with DNA was not classical intercalation. These results were further supported by viscosity method and competitive binding experiment. Scatchard analysis suggests that the interaction mode was a mixed binding, which contains partial intercalation and groove binding. |
