Abstract:
A series of 1, 2, 4-oxadiazole derivatives have been designed and synthesized, and 25 compounds were evaluated their abilities by the assay of cAMP concentration in GPR119-transfected HEK293T cells. All compounds showed acceptable agonistic effects on GPR119. Among these compounds, 4p exhibited the best agonistic effects with the EC50 of 20.6 nm, which was comparable to that of positive control GPR119 agonist GSK1292263. The agonistic activity of these 1,2,4-oxadiazole derivatives led to the establishment of a structure-activity relationship.

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.
