A synergistic composition comprising as active ingredients a PGF.sub.2.sub..alpha. compound or its cyclodextrin clathrate thereof and a PGE.sub.2 compound or its cyclodextrin clathrate thereof, at a weight ratio of from about 1:0.33 to about 1:1.
chain was performed to improve EP2 agonist activity and subtypeselectivity. Phenoxy derivative 18a showed potent agonist activity and excellent subtypeselectivity. Furthermore, a series of compounds were identified as G protein-biased EP2 receptoragonists. These are the first examples of biased ligands of prostanoid receptors.
Disclosed herein are novel prostaglandin I.sub.2 (PGI.sub.2) derivatives exhibiting excellent in vivo duration and activities, said derivatives being represented by the general formula: ##STR1## wherein R.sub.1, X, R.sub.2 and R.sub.3 are as defined herein.
