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 کاملA simple and sensitive spectrophotometric determination of monoamine oxidase activity.
A simple, sensitive Spectrophotometric determination of monoamine oxidase activity from tissue homogenates is described. This method is based on the high extinction coefficient of 4-hydroxy-3-methoxy-benzaldehyde (vanillin) at 345 nm at pH ~ 11.7. Vanillin is formed by inonoamine oxidase when 4-hydroxy-3-methoxy-benzylamine is used as substrate. The primary oxidation product, 4-hydroxy-3-methox...
متن کاملHuman platelet monoamine oxidase activity in glaucoma.
Monoamine oxidase (MAO, E.C. 1.4.3.4) activity was determined by spectrophotofluorimetric assay of the reaction product of the artificial substrate kynuramine in platelets from venous blood samples from 50 outpatients with glaucomas and 47 sex- and age-matched controls. No significant differences were found between MAO activity in control subjects and that in subjects with glaucomas grouped acc...

rich with LAF, identified as a macrophage product. However, different mononuclear cell subpopulations might be responsible for the higher production of LAF and KAF under similar conditions. This possibility is under investigation, with the use of purified populations of lymphocytes or macrophages obtained from human peripheral blood. The conditions that affect corneal wound healing at the molec...
