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...

Inhibition of monoamine oxidase by stilbenes from Rheum palmatum
Seven stilbenes and one catechin were bioactivity-guidedly isolated from the rhizomes of Rheum palmatem. Their structures were identified as piceatannol(1), resveratrol(2), piceid(3), rhapontigenin(4), piceatannol-3'-O-β-D-glucopyranoside(5), rhaponticin(6), catechin(7) and desoxyrhapontigenin(8). Anti-monoamine oxidase (MAO) activities of compounds 1–8 were tested. Compounds 1 and 8 showed sig...
متن کاملAn evaluation of phospholipids as regulators of monoamine oxidase A and monoamine oxidase B activities.
When rat liver mitochondria are treated with the phospholipase A2 isolated from Naja naja venom in amounts sufficient to cause about 70% loss of mitochondrial phospholipids, both of the monoamine oxidase isozymes monoamine oxidase A and monoamine oxidase B are reduced in activity. With both monoamine oxidases, phospholipase treatment affects the enzyme’s affinity for the amine substrates rather...
