xenobiotics by glucose oxidase from Aspergillus niger. The following compounds are readily reduced by d-glucose, in the presence of glucose oxidase: p-nitroso-N,N-dimethylaniline, methyl-1,4-benzoquinone, and 7,7,8,8-tetracyano-quinodimethane. In each case, the products of enzymatic reduction undergo a dismutation reaction with the parent compound and thus afford the formation of free radicals. In some cases
在本通讯中,我们描述了黑曲霉的葡萄糖氧化酶对几种异源生物的活化作用。在葡萄糖氧化酶的存在下,下列化合物很容易被d-葡萄糖还原:对-亚硝基-N,N-二甲基苯胺,甲基-1,4-苯醌和7,7,8,8-四氰基-喹二甲烷。在每种情况下,酶促还原产物都会与母体化合物发生歧化反应,从而形成自由基。在某些情况下,在合适的pH值下,母体化合物向自由基的转化几乎是定量的。在最佳条件下,自由基在生理条件下的水溶液中稳定几分钟。
