The superoxide-dismutase-like activity of a series of divalent metal saccharinates of general stoichiometry [MII(Sac)2(H2O)4].2H2O (with MII = Mn,Fe,Co,Ni,Cu,Zn) has been investigated using the nitroblue tetrazolium O2- reduction assay. The results show that all these complexes possess the capability to dismutate the superoxide anion generated in the xanthine/xanthine oxidase system. Interestingly, the greatest activity is shown by the corresponding copper complex. The results are discussed and compared with those obtained for native superoxide dismutase, which was tested under the same experimental conditions.
采用氮蓝四唑超氧阴离子还原法研究了一系列化学计量比为[MII(Sac)2(H2O)4].2H2O（MII = Mn、Fe、Co、Ni、Cu、Zn）的二价金属糖精配合物的类超氧化物歧化酶活性。结果表明，所有这些配合物都具有使黄嘌呤/黄嘌呤氧化酶系统中产生的超氧阴离子歧化的能力。有趣的是，相应的铜配合物表现出最大活性。对结果进行了讨论，并与在相同实验条件下测试的天然超氧化物歧化酶的结果进行了比较。
