Multiple 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 کاملVisualization of monoamine oxidase in human brain.
11973 Monoamine oxidase (MAO; EC: 1.4.3.4) is a flavin containing enzyme which exists in two subtypes, MA0 A and MA0 B. MA0 A and B are different gene products and they also differ in their substrate and inhibitor selectivities and their cellular localizations. In human brain MA0 B predominates (B:A = 4:l) and is largely compartmentalized in cell bodies of serotonergic neurons and in glia. Many...
متن کاملEffect of cadmium and zinc ethanolamine complexes on rat brain monoamine oxidase-B activity in vitro.
Monoamine oxidase-B (MAO-B) from rat brain was inhibited strongly by the prepared cadmium and zinc ethanolamine complexes obtained from their sulphate and chloride salts. The inhibition of MAO-B by these complexes was time-dependent and fully reversible after dilution and sedimentation. In vitro, the cadmium ethanolamine complexes were more potent at inhibiting MAO-B than the zinc complexes. Th...
متن کاملMonoamine oxidase-B mediates ecstasy-induced neurotoxic effects to adolescent rat brain mitochondria.
3,4-Methylenedioxymethamphetamine (MDMA)-induced neurotoxicity and the protective role of monoamine oxidase-B (MAO-B) inhibition were evaluated at the mitochondrial level in various regions of the adolescent rat brain. Four groups of adolescent male Wistar rats were used: (1) saline control, (2) exposed to MDMA (4 x 10 mg/kg, i.p.; two hourly), (3) treated with selegiline (2 mg/kg, i.p.) 30 min...
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...
