cycloalkyl and cycloalkenyl analogues of enisoprost was synthesized to investigate the effects of omega chain unsaturation on gastric antisecretory activity and diarrheogenic side effects. Of these, the 17E, 18-cyclopentenyl analogue 5d displayed potent gastric antisecretory activity in dogs but very weak diarrheogenic properties in rats and is the most selective prostaglandin compound discovered in these
