Abstract
This invention relates to certain structural and pharmacological analogs of prostacyclin (PGI.sub.2) and 5,6-dehydroprostacyclin (PGI.sub.1) and 5,9.alpha.-epoxy-9-deoxy-PGF.sub.1, wherein between the position beta to the carboxy (C-2) and C-5 there is substituted an inter-o-phenylene for the ethylene chain. These novel 2,5-inter-o-phenylene-3,4-dinor-prostaglandin or prostacyclin-type compounds are useful for certain of the same pharmacological purposes as prostacyclin, particularly being smooth muscle stimulators, blood pressure depressors and platelet aggregation inhibitors. Also provided are novel intermediates therefor, namely corresponding interphenylene-containing PGF.sub.2.alpha. and 5-halo-PGI.sub.1 and 6-halo-5,9.alpha.-epoxy-9-deoxy-PGF.sub.1 compounds.
