Show results in: Español

  • Dopamine

    Furthermore, the oxidase-like activity of Fe/NC-800 was significantly inhibited by dopamine (DA), leading to blue color fading.[] VAP-1 (AOC3) can also deaminate short-chain primary amines. The main end product of DA metabolism is homovanillic acid (HVA), which is excreted to urine by the kidneys .[] L-Phenylalanine (and L-Tyrosine) leads to increased alertness and arousal A peer-reviewed paper published in 2008 concluded that L-Tyrosine and L-Phenylalanine are precursors[] The drug is on the WHO official list. dopamine the decarboxylation product of DOPA .

  • Norepinephrine

    DHPG is formed when norepinephrine is incubated with aldose reductase in the presence of monoamine oxidase.[] The amino acid supplements L-tyrosine and L-phenylalanine increase norepinephrine production, but must be used cautiously, especially if you are bipolar, according to Emmons[] This is followed by decarboxylation into the neurotransmitter dopamine. Last is the final β-oxidation into norepinephrine by dopamine beta hydroxylase.[] -DOPS) Etilevodopa Ephedrine Ergotamine Epinephrine Etilefrine Ethylnorepinephrine Guanabenz Guanfacine Guanoxabenz L -DOPA (levodopa) L -Phenylalanine L -Tyrosine Lofexidine[] Up to 16% of an intravenous dose is excreted unchanged in the urine with methylated and deaminated metabolites in free and conjugated forms.[]

    Abstract During 4 weeks of treatment with clorgyline, a selective MAO-A inhibitor, platelet monoamine oxidase (MAO) activity was unchanged.[] […] of lnorepinephrine dopamine and serotonin 517 Oxidative deamination of trace amines in the brain A A Boulton B A Davis D 539 Platelet MAO activity in depressed patients Jean[] -DOPA (levodopa) Dopamine 5-HTP Serotonin L -Histidine Histamine Phenylalanine Phenethylamine L -Tyrosine Tyramine Tryptophan Tryptamine Inhibitors: Benserazide Carbidopa[] The volume presents a collection of research papers on monoamine oxidase and its inhibitors.[] MAO-A preferentially deaminates serotonin, melatonin, epinephrine and norepinephrine. MAO-B preferentially deaminates phenylethylamine and trace amines.[]

  • Chloroquine

    METHODS: Differential metabolism of PQ enantiomers by recombinant human CYP2D6, monoamine oxidase A (MAO), and cryopreserved human hepatocytes in the presence/absence of CQ[] Oxytetracycline, Molecular Formula of Omeprazole, Oxyphenbutazone, Pancuronium Bromide, Paracetamol, Papaverine, Penicilling, Pentazocine, Synonyms of Pentoxifylline, Synonyms of L-Phenylalanine[] The formation of the primary deaminated metabolites, including carboxyprimaquine (CPQ) and cyclized side chain derivative from the aldehyde (m/z 241), was not sensitive to[]

  • Molindone

    Despite these similarities, molindone also has atypical properties and inhibits the enzyme monoamine oxidase in vitro and in vivo.[] 24 h pretreatment with molindone enhanced the behavioural effects of L-dopa and 5-HTP, precursors of biogenic amines (catecholamines and 5-HT respectively) preferentially deaminated[] -DOPA (levodopa) Melevodopa L -Phenylalanine L -Tyrosine XP21279 Others A-68930 Apomorphine Isocorypalmine Nuciferine Propylnorapomorphine Rotigotine SKF-89,145 SKF-89,626[] -DOPA (levodopa) Melevodopa L -Phenylalanine L -Tyrosine XP21279 Others : A-68930 Apomorphine Isocorypalmine Nuciferine PF-6649751 PF 6669571 Propylnorapomorphine Rotigotine[] -DOPA (levodopa) L -Phenylalanine L -Tyrosine Melevodopa XP21279 Atypical antipsychotics Alentemol (U-66444B) Aripiprazole ( sertraline) Aripiprazole lauroxil Bifeprunox Brexpiprazole[]

  • Catha Edulis

    Abstract The possibility that phenylalkylamines (cathinone and cathine) of khat, like amphetamines, are amine oxidase inhibitors with clinical significance is evaluated.[] These secondary metabolites are produced in planta through a L-phenylalanine derived multi-step pathway.[] These two distantly related enzymes (Green, 1989) share the common step of pyruvate decarboxylation.[] In contrast with AHAS, carboligation is only a minor side reaction for PDC; the latter enzyme largely performs pyruvate decarboxylation to form acetaldehyde and CO 2 .[] Theoretically, concurrent use of khat with monoamine oxidase inhibitors may cause hypertensive (high blood pressure) crisis.[]
