    摘要: Prostacyclin, although having a useful dilating effect on blood vessels, is not sufficiently stable to ensure successful use as a hypotensive agent.A 7-oxo prostacyclin derivative of the general formula ##STR1## in which R.sub.1 represents the radical OR.sub.3 whereinR.sub.3 represents hydrogen, a straight-chain or branched optionally substituted, (C.sub.1 -C.sub.10)alkyl, optionally substituted aryl, optionally substituted cycloalkyl, optionally substituted heterocyclic,orR.sub.1 represents the radical NHR.sub.4 whereinR.sub.4 represents hydrogen, or a group derived from an unsaturated or saturated, unsubstituted or substituted, (C.sub.1 -C.sub.15)organic carboxylic or sulphonic acid,A represents --CH.sub.2 --CH.sub.2 --, cis--CH.dbd.CH-- or trans--CH.dbd.CH--,W represents ##STR2## either having a free or functionally modified hydroxy group which may be in the .alpha.- or .beta.-position,D and E together represent a direct bond, orD represents a straight-chain or branched, unsaturated or saturated, optionally substituted (C.sub.1 -C.sub.10)alkylene, andE represents oxygen or a direct bond,R.sub.2 represents a straight-chain or branched optionally substituted, (C.sub.1 -C.sub.10)alkyl, a straight-chain or branched optionally substituted, (C.sub.2 -C.sub.10)alkenyl, or, where D and E together represent a direct bond, a straight-chain or branched optionally substituted (C.sub.2 -C.sub.6)alkynyl,andR.sub.5 represents a free or functionally modified hydroxy group,has proved to have not only a hypotensive and bronchodilative action, for example, but also an increased stability over prostacyclin. Advantages in medicinal use over other prostaglandins have also been found.
