ChEBI ID CHEBI:63916
Definition A carbobicyclic compound that is prostaglandin I2 in which the endocyclic oxygen is replaced by a methylene group and in which the (1E,3S)-3-hydroxyoct-1-en-1-yl side chain is replaced by a (3R)-3-hydroxy-4-methyloct-1-en-6-yn-1-yl group. A synthetic analogue of prostacyclin, it is used as the trometamol salt (generally by intravenous infusion) for the treatment of peripheral vascular disease and pulmonary hypertension.
