Abstract:
We studied the binding of (+)(3)H-amphetamine to membrane sites from rat hypothalamus. Our experiments demonstrate the possible existence of artefactual results in previous studies due to the inadequate use of a filtration technique. In addition, it seems that monoamine oxidase A might be a component of the complex mixture of binding sites which are recognized by (+)(3)H-amphetamine since harmaline and monoamine oxidase A selective inhibitors are good displacers of this ligand.

Adrenergic Agonists: Indirect-Acting Agents
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
