Description
The present invention relates to prostaglandin analogs for which the essential material constituting a disclosure therefor is incorporated by reference here from U.S. Pat. No. 4,016,184, issued Apr. 5, 1977.
Claims
I claim:
1. A prostaglandin analog of the formula ##STR2## wherein Y is cis--CH.dbd.CH-- or trans--CH.dbd.CH--; wherein m is one to 5, inclusive; Wherein M.sub.1 is ##STR3## or ##STR4## wherein R.sub.5 and R.sub.6 are hydrogen or methyl, with the proviso that one of R.sub.5 and R.sub.6 is methyl only when the other is hydrogen; Wherein L.sub.1 is ##STR5## or a mixture of ##STR6## and ##STR7## wherein R.sub.3 and R.sub.4 are hydrogen, methyl, or fluoro, being the same or different, with the proviso that one of R.sub.3 and R.sub.4 is fluoro only when the other is hydrogen or fluoro; Wherein R.sub.1 is hydrogen, alkyl of one to 12 carbon atoms, inclusive, cycloalkyl of 3 to 10 carbon atoms, inclusive, aralkyl of 7 to 12 carbon atoms, inclusive, phenyl, phenyl substituted with one, two, or three chloro or alkyl of one to 3 carbon atoms, inclusive, or a pharmacologically acceptable cation; and Wherein Z.sub.9 is ##STR8## WHEREIN G IS ONE, 2, OR 3.
