Catecholamines (C0007412)
|
|---|
| Definition (MSH) | A general class of ortho-dihydroxyphenylalkylamines derived from tyrosine. |
| Definition (CSP) | any of various substances that contain a benzene ring with two adjacent hydroxyl groups and a side chain of ethylamine and that function as hormones or neurotransmitters or both; examples are dopamine, norepinephrine, and epinephrine. |

Adrenergic Receptor (C0034783)
|
|---|
| Definition (MSH) | Cell-surface proteins that bind epinephrine and/or norepinephrine with high affinity and trigger intracellular changes. The two major classes of adrenergic receptors, alpha and beta, were originally discriminated based on their cellular actions but now are distinguished by their relative affinity for characteristic synthetic ligands. Adrenergic receptors may also be classified according to the subtypes of G-proteins with which they bind; this scheme does not respect the alpha-beta distinction. |
| Definition (CSP) | family of G protein coupled receptors sensitive to epinephrine, norepinephrine, and their analogs, found in smooth and cardiac muscle, autonomic ganglia, brain, and elsewhere. |
| Concepts | Amino Acid, Peptide, or Protein (T116)
, Receptor (T192)

| English | ADREN RECEPT, Adrenergic Receptor, Adrenergic receptor site, adrenergic receptors, Adrenoceptors, adrenoreceptor, EPINEPHRINE RECEPT, Epinephrine Receptors, RECEPT ADREN, RECEPT EPINEPHRINE |
| Spanish | receptor adrenérgico, receptor adrenergico |

Sympathomimetics (C0039052)
|
|---|
| Definition (MSH) | Drugs that mimic the effects of stimulating postganglionic adrenergic sympathetic nerves. Included here are drugs that directly stimulate adrenergic receptors and drugs that act indirectly by provoking the release of adrenergic transmitters. |
| Concepts | Pharmacologic Substance (T121)
|
| English | Sympathomimetic, sympathomimetic agent, Sympathomimetic Agents, Sympathomimetic compound, Sympathomimetic Drugs, Sympathomimetics |
| Spanish | agente simpaticomimético, agente simpaticomimetico, compuesto simpaticomimético, compuesto simpaticomimetico, simpaticomimético, simpaticomimetico |
