A series of prostacyclin receptor agonists was prepared by modifying the central heteroaromatic ring of lead compound 2, and a docking study was performed to investigate their structure-activity relationships by using a homology-modeled structure of the prostacyclin receptor. Compound 2 and its derivatives could be docked to the prostacyclin receptor in two ways depending on the position of the nitrogen atom within the heteroaromatic ring. Furthermore, hydrogen bonding between the nitrogen atom in the heteroaromatic ring and the hydroxyl group of Ser20 or Tyr75 of the receptor appears to be important for the potent expression of biological activity.
