Abstract:
Twelve normal weight healthy male volunteers participated in a double-blind, placebo-controlled trial of the effects of d- and l-fenfluramine, d-amphetamine, and the interactions between the two isomers of fenfluramine with amphetamine, on cortisol secretion. d-Fenfluramine and d-amphetamine in combination produced the greatest cortisolaemic effect, suggesting that they act by differing neurochemical pathways. d-Fenfluramine produced a significant effect, but l-fenfluramine produced little effect, suggesting that the cortisol-releasing properties of racemic fenfluramine reside in the d-isomer.

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: Mixed-Action Agents
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...
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.
Separation of the aromatic...
