| 摘要 |
This invention relates to certain structural and pharmacological analogs of 5,6-dihydro-prostacyclin (PGI1) wherein the C-4 position is substituted by oxo. These novel 4-oxo-prostacyclin-type compounds are useful for the same pharmacological purposes as prostacyclin, particularly being smooth muscle stimulators and platelet aggregation inhibitors.
