Abstract:
N6-(2-Hydroxyethyl) adenosine, HEA (1), an active ingredient isolated from cultured mycelia of cordyceps species which is a famous traditional tonic in China, showed brain protective, sedative hypnotic activity in pharmacological tests. In order to explore novel non-benzodiazepine sedative-hypnotic agents, HEA was treated as the lead compound. Twenty three target compounds were designed and synthesized. Their chemical structures were characterized by 1H NMR, MS and elemental analysis. Pharmacological test in vivo showed that target compounds 8, 4, 13 were more active than HEA on locomotor and gasping activities of mice. Structure-activity relationships showed that the ribose moiety at N-9 position of adenine base was critical for activity.

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.

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...
