A Peroxidase-linked Spectrophotometric Assay for the Detection of Monoamine Oxidase Inhibitors
To develop a new more accurate spectrophotometric method for detecting monoamine oxidase inhibitors from plant extracts, a series of amine substrates were selected and their ability to be oxidized by monoamine oxidase was evaluated by the HPLC method and a new substrate was used to develop a peroxidase-linked spectrophotometric assay. 4-(Trifluoromethyl) benzylamine (11) was proved to be an exc...

متن کاملThe reaction of ferrous horseradish peroxidase with hydrogen peroxide.
Hydrogen peroxide reacts with ferrous horseradish peroxidase and converts it to oxyperoxidase in a sequence of two reactions. The first is the reaction of ferrous peroxidase with HzOz to form Compound II; the second is the reaction of Compound II with HzOz to form oxyperoxidase. Both reactions follow second order kinetics, being first order with respect to each of the reactants. They proceed wi...
متن کاملReaction of Thiol Compounds with Peroxidase and Hydrogen Peroxide*
Recent studies have indicated that peroxidase might function in the biological synthesis of thyroxine by the thyroid gland. Johnson and Tewkesbury (1) believed that thyroxine might be formed by the oxidative coupling of 2 molecules of diiodotyrosine. Westerfeld and Lowe (2) studied the oxidative condensation of p-cresol by hydrogen peroxide and peroxidase and suggested that peroxidase might be ...
