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.

Abstract: 2,2-Difluoro prostaglandin E, F.sub..alpha., F.sub..beta., A, and B analogs are disclosed with intermediates and with processes for making them. These compounds differ from the prostaglandins in that they have two fluoro atoms at the C-2 position in place of the two hydrogen atoms at C-2 in the prostaglandins. These compounds are useful for a variety of pharmacological purposes, including antiulcer, inhibition of platelet aggregation, increase in nasal patency, labor induction at term, and wound healing.
