Studies on monoamine oxidase. (Report XXV). Effects of alcohols on beef liver mitochondrial monoamine oxidase.
The effects of alcohols on MAO activity in beef and rat liver mitochondria were studied. MAO activity was determined manometrically using tyramine (1× 10-2 M) as substrate and expressed as O2 uptake in 60 min. At concentrations of 0.1 to 10%, methanol and ethanol increased MAO activity in both beef and rat liver mitochondria. Activation of MAO by ethanol was reversib...
متن کاملInhibition 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 کاملMultiple Forms of Rat Liver Monoamine Oxidase
1. Treatment of a partly purified preparation of rat liver monoamine oxidase with the chaotropic agent sodium perchlorate caused the enzyme to migrate as a single band of activity on polyacrylamide-gel electrophoresis, whereas the untreated enzyme separated into a number of bands. 2. Treatment with the chaotropic agent caused no loss ofenzyme activity towards benzylamine, dopamine or tyramine. ...
متن کاملMonoamine oxidase: radiotracer development and human studies.
Monoamine oxidase (MAO) is an integral protein of outer mitochondrial membranes and occurs in neuronal and nonneuronal cells in the brain and in peripheral organs. It oxidizes amines from both endogenous and exogenous sources, thereby influencing the concentration of neurotransmitter amines as well as many xenobiotics. It occurs in two subtypes, MAO A and MAO B, which are different gene product...
