Additional double bonds were introduced into the alpha chain in 16-phenoxy-, 16-(3-chlorophenoxy)-, 16-[3-(tri-fluoromethyl)phenoxy]-, and 16-(4-chlorophenoxy)-17,18,19,20-tetranorprostaglandins which have antinidatory effects. Of these analogues, the delta 3-cis-delta 5 analogues 23b is 1200 times more potent than prostaglandin F2 alpha in antinidatory effect in the rat and more potent than any other known prostaglandin analogues.
