Activity and thermosensitivity of canine cutaneous veins after inhibition of monoamine oxidase and catechol-O-methyl transferase.

The lateral saphenous vein of the dog was perfused with homologous blood at constant flow. Changes in driving pressure were used to measure active changes in venous tone. Administration of tranylcypromine greatly reduced the activity of monoamine oxidase in the vein and increased its response to electric stimulation of the lumbar sympathetic chain and to norepinephrine infusions. Administration...

Catechol-o-methyl Transferase and Monoamine Oxidase Activity in the Ocular Tissues of Albino Rabbits.

The distribution of catechol-O-methyl transferase and monoamine oxidase activity in the ocular tissues of albino rabbits has been determined with a radioactive tracer assay. The distribution of the former varied in the different tissues within a restricted range whereas the distribution of monoamine oxidase activity exhibited larger variations. Sympathetic denervation did not appear to affect c...

Catechol-O-methyl transferase and schizophrenia.

Catechol-O-methyl transferase (COMT) is an enzyme involved in the degradation of dopamine. The most commonly examined polymorphism within the COMT gene is Val108/158Met polymorphism, which results in three to fourfold difference in COMT enzyme activity. It is particularely important in prefrontal cortex, since COMT activity is the most important regulator of the prefrontal dopamine function. Gi...

Methionine sulfoxide reductase regulates brain catechol-O-methyl transferase activity.

Catechol-O-methyl transferase (COMT) plays a key role in the degradation of brain dopamine (DA). Specifically, low COMT activity results in higher DA levels in the prefrontal cortex (PFC), thereby reducing the vulnerability for attentional and cognitive deficits in both psychotic and healthy individuals. COMT activity is markedly reduced by a non-synonymous single-nucleotide polymorphism (SNP) ...

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...
