应用氮蓝四唑(NBT)-光照法研究了系列诺氟沙星(NFA)-铜(Ⅱ)-多吡啶配合物:[Cu(NFA)(tatp)(H2O)](ClO4)2(1),[Cu(NFA)(bipy)(H2O)](ClO4)2.2.5H2O(2)和[Cu(NFA)(dppz)(H2O)](ClO4)2.H2O(3)[NFA=诺氟沙星,tatp=1,4,8,9-四氮三联苯,bipy=1,1’-联二吡啶,dppz=二吡啶并[3,2-a;2’,3’-c]吩嗪]在水溶液中的超氧化物岐化酶(SOD)活性,并用循环伏安法研究了配合物的电化学性质。结果表明,三种配合物均具有良好的SOD活性,表观催化速率常数分别为6.34×107、3.74×107和7.17×107mol-1.L.S-1。
The effects of NFA - Cu (Ⅱ) - polypyridine complex: [Cu (NFA) (tatp) (H2O)] (ClO4) 2 (1 ), [Cu (NFA) (bipy) (H2O)] (ClO4) 2.2.5H2O and [Cu (NFA) (dppz) (H2O)] (ClO4) Tetracyclobutene, bipy = 1,1’-bipyridyl, dppz = dipyrido [3,2-a; 2 ’, 3’-c] The activity of superoxide dismutase (SOD) in aqueous solution was studied. The electrochemical properties of the complex were investigated by cyclic voltammetry. The results showed that all the three complexes have good SOD activity, apparent catalytic rate constants were 6.34 × 107,3.74 × 107 and 7.17 × 107mol-1.L.S-1.
