Disclosed are prostaglandin analogues having the structural formula, <IMAGE> (I) in which: T is selected from the group consisting of carboxyl, alkoxycarbonyl or cyano; M is selected from the group consisting of carbonyl, R-hydroxymethylene or S-hydroxymethylene; L is selected from the group consisting of methylene or methine, provided L is methine only if J is methine; J is selected from the group consisting of methylene, ethylene, R-hydroxymethylene, S-hydroxymethylene or methine, provided J is methine only if L is methine; W is selected from the group consisting of <IMAGE> T1 and T2 are attached to adjacent carbon atoms; T1 is selected from the group consisting of hydrogen or phenyl, provided T1 is phenyl only if T2 is lower alkyl; T2 is selected from the group consisting of n-pentyl or lower alkyl, provided T2 is lower alkyl only if T1 is phenyl; or T1 and T2 are joined together to form an alkylene group of 4 or 6 carbon atoms. Also disclosed are methods for preparing such prostaglandin analogues. |
