Abstract:
A series of human androgen receptor (hAR) agonists based on 4-alkyl-; 4,4-dialkyl-; and 3,4-dialkyl-1,2,3,4-tetrahydro-8-pyridono[5,6-g]quinoline was synthesized and evaluated in competitive receptor binding assays and an androgen receptor cotransfection assay in a mammalian cell background. A number of compounds in this series demonstrated activity equal to or better than dihydrotestosterone in both assays and represent a novel class of compounds for use in androgen replacement therapy.

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.
