The method for assaying the SOD (super oxide dismutase) activity in liquid medium is based on the activation of self-oxidization, by SOD activity, of a reactive agent having the general formula (I) wherein either n is 1 or 2, R.sup.1 is --OR.sup.4 or --NR.sup.5 R.sup.6 ; R.sup.2 is H, --OR.sup.4, alkyl (1-6C), --CH.sub.2 -- or --CH.sub.2 --CH.sub.2 --, to form a ring by binding to the phenyl substituent, at meta with respect to R.sup.1 ; and R.sup.3 is H, alkyl (1-6C) or --OR.sup.4 (if R.sup.2 is different from --OR.sup.4); with R.sup.4 being H or alkyl (1-6C); R.sup.5 being H, alkyl (1-6C), --CH.sub.2 COOH, --C.sub.6 H.sub.5 COOH or --C.sub.6 H.sub.5 SO.sub.3 H; and R.sup.6 is H, alkyl (1-6C) or --CH.sub.2 COOH; or n is 1, R.sup.1 is --OR.sup.4, R.sup.2 is --CH.sub.2 --O--, in order to form a ring by bonding of O with the phenyl substituent, at meta with respect to R.sup.1 ; and R.sup.3 is H or --OR.sup.4. Application to assaying the SOD activity in a sample, specially a biological sample, particularly by a single measurement and one calibrating curve.
在液体培养基中测定SOD(超氧化物歧化酶)活性的方法基于自氧化的激活,通过SOD活性,使用具有通式(I)的反应试剂,其中n为1或2,R.sup.1为--OR.sup.4或--NR.sup.5R.sup.6;R.sup.2为H,--OR.sup.4,烷基(1-6C),--CH.sub.2--或--CH.sub.2--CH.sub.2--,通过与苯基取代物在meta位置与R.sup.1结合形成环;R.sup.3为H,烷基(1-6C)或--OR.sup.4(如果R.sup.2与--OR.sup.4不同);其中R.sup.4为H或烷基(1-6C);R.sup.5为H,烷基(1-6C),--CH.sub.2COOH,--C.sub.6H.sub.5COOH或--C.sub.6H.sub.5SO.sub.3H;R.sup.6为H,烷基(1-6C)或--CH.sub.2COOH;或n为1,R.sup.1为--OR.sup.4,R.sup.2为--CH.sub.2--O--,通过O与苯基取代物在meta位置与R.sup.1结合形成环;R.sup.3为H或--OR.sup.4。适用于测定样品的SOD活性,特别是生物样品,尤其是通过单次测量和一个校准曲线。
