Abstract:
Many important drugs act via the activation or blockade of adrenergic receptors. Although research has been ongoing in this area for over fifty years, the continual subdivision of the major adrenoceptor classes has provided new opportunities for drug discovery. This review focuses on the recent developments directed towards a few of the many potential targets now available. While there is a rationale to suggest that limiting pharmacological activity to one particular subtype may improve the therapeutic profile for some indications, it is also possible for a drug to have beneficial effects resulting from interactions with multiple adrenergic receptor subtypes.

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...

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.
