To reveal an enzyme-like catalytic activity of metal-octabromo-tetrakis(sulfophenyl)porphines (M-OBPSs), their peroxidease-like catalytic activity on linoleate hydroperoxide (LOOH) were evaluated on the basis of dye-formation in the coloring reaction between N,N-diethylaniline and 4-aminoantipyrine that yields a quinoid-type dye. Among M-OBPSs tested, Mn 3+ -OBPS allowed to produce the largest...
The ion-exchange resins modified with metal–porphyrins and –phthalocyanines (M–P r ) have been found to exhibit a peroxidase (POD)-like activity on organic peroxides in a reaction wherein a quinoid dye is formed from phenol and 4-aminoantipyrine. Among them, Mn– and Co–P r exhibited stronger activity than hemoglobin and Fe–P r , and hence were expected to be practically useful...
