Monoamine oxidase of bovine kidney mitochondria has been purified to high specific activity by solubilization with digitonin, ammonium sulfate fractionation, and calcium phosphate gel-cellulose column chromatography. Absorption and fluorescence spectra indicated strongly that mitochondrial monoamine oxidase is a flavoenzyme. Under anaerobic conditions, benzylamine reduced the flavin at 460 rnp ...

Glutamate kills neuronal cells by either a receptor-mediated pathway or the inhibition of cystine uptake, the "oxidative pathway." Antioxidants can block cell death initiated by either pathway, suggesting that toxicity is dependent on the production of free radicals. We provide evidence that in a neuronal cell line, glutamate toxicity via the oxidative pathway requires monoamine metabolism as a...

recent years have seen a large increase in the prescription of antidepressants in the UK. this is a field in which both research and clinical practice are developing rapidly. a new generation of ‘designer drugs’ has largely replaced the tricyclic antidepressants and monoamine oxidase inhibitors, on grounds of safety and tolerability rather than improved efficacy. drugs have been developed on th...

Ladostigil is a novel drug that inhibits acetyl and butyrylcholinesterase, and monoamine oxidase (MAO) A and B selectively in the brain. It reverses memory deficits induced by chronic inhibition of cortical cytochrome oxidase in rats and has anxiolytic and antidepressant-like activity in prenatally-stressed rats. Ladostigil also prevents oxidative-nitrative stress induced in astrocytes in the h...

Controlled osmotic lysis (water-washing) of rat liver mitochondria results in a mixed population of small vesicles derived mainly from the outer mitochondrial membrane and of larger bodies containing a few cristae derived from the inner membrane. These elements have been separated on Ficoll and sucrose gradients. The small vesicles were rich in monoamine oxidase, and the large bodies were rich ...
