Abstract
A scheme is proposed for the qualitatively different catalytic effects of metalloporphyrins in reactions involving the oxidation of epinephrine. A metallocomplex of porphyrin may accelerate the oxidation of some substances and inhibit the oxidation of others. The small value of the constant of regeneration of the catalyst gives a similar effect, i.e., the oxidation of a given substance may be accelerated by one metallocomplex and inhibited by others. The catalytic oxidation of epinephrine in the presence of the cobalt complex of porphyrin at biological pH values that we have detected is of undoubted interest for understanding the regulatory role of metalloporphyrins in living organisms.
