    Study Notes

    ATPase

    • Extrusion de cationes, especialmente calcio.
    • Enzymes functionanse como catalizadores biologicos: rapidece reactiones químicas.
    • Exemplo: MAO (Monoamine Oxidase) participa in metabolism de aminas biogenicas.

    Metabolism de Aminas Biogenicas

    • MAO A et MAO B implicate in metabolism de norepinephrine (NE), epinephrine (Epi), e dopamine.
    • Disciplina de enfermedad major depression implica disalination de NE e serotonin (5-HT).
    • Parkinsonismo caracterizate per diminution de dopamine.

    Medicamentos

    • Digoxin actua in contractilitate cardiaca.
    • MAOIs (Inhibitores de MAO) altere concentrasiones de aminas biogenicas.

    Interferentia de Drugs

    • Interfere con DNA e metabolismo intermediarie.
    • Inibition de synthese de DNA mediante antimetabolites.
    • Exemples: Mercaptopurina, Thioguanine, 5-fluorouracil, Cytarabine.

    Interacciones de Receptores de Medicamentos

    • Caracteristicas de receptores inclue afinidade de ligando, capace de vincular.
    • Diferente effectos de ligandos que targeta le stesso receptor, como NE versus Propranolol.
    • Substratos como Hydralazine e Isoniazid son saturabile e subjecte a Michaelis-Menten.

    Neurones e Autoreceptores

    • Autoreceptores in neurones exercita effecto inhibitory, impede liberazione de neurotransmittedores.
    • Majority de receptores localizate in post-synapse.

    Efectos Central e Peripherale

    • Efectos centrales incluyen sedativitate e depression.
    • Exocitosis e vasodilatation somma interacciones de neurotransmittedores.
    • Reuptake inhibition resulta in concentration elevate de neurotransmittedores in cleft synaptic.
