席夫碱Cu（II）配合物与鲱鱼精DNA的相互作用研究

摘要

The interaction of schiff base copper complex and herring sperm DNA was studied by cyclic voltammetry,UV-Vis and flu-orescence methods. Adding DNA into the schiff base copper complex solution,the redox peak current decreased and the peak poten-tial shifted to positive. Moreover,the ultraviolet absorption intensity of DNA was strengthened by the schiff base copper complex,and the fluorimetric intensity of schiff base copper complex was increased by DNA. All results showed that the schiff base copper com-plex and DNA was interacted according to the mode of intercalation.%采用电化学和光谱法,研究了糠醛缩对氨基苯磺酸席夫碱Cu( II)配合物与鲱鱼精DNA的相互作用。结果发现：糠醛缩对氨基苯磺酸席夫碱Cu( II)中加入DNA后,氧化还原峰电流降低,式量电位正移；席夫碱Cu(II)配合物使DNA的最大吸收峰强度增强,DNA使席夫碱Cu(II)配合物的荧光强度增强。表明席夫碱Cu( II)配合物以嵌插模式与DNA作用。
