Abstract:
1,3-Disubstituted-5-aminopyrazoles were prepared based on a lead compound found through high-throughput screening of our corporate compound library in an assay measuring affinity for the human neuropeptide Y5 receptor. The target compounds were prepared by cyclization of alpha-cyanoketones with appropriate hydrazines, followed by reduction and coupling to various sulfonamido-carboxylic acids. Several of these arylpyrazoles (e.g., 19 and 45) displayed high affinity for the human NPY Y5 receptor (<20nM IC(50)s).

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...
