5,6-Didehydro-.omega.-phenoxy-PGE.sub.2 analogs

Abstract

This invention comprises certain analogs of the prostaglandins in which there is a triple bond between C-5 and C-6 or C-4 and C-5. Also provided in this invention, are novel chemical processes useful in the preparation of the above prostaglandin analogs. These prostaglandin analogs exhibit prostaglandin-like activity, and are accordingly useful for the same pharmacological purposes as the prostaglandins. Among these purposes are blood pressure lowering, labor induction at term, reproductive-cycle regulation, gastric antisecretory action, and the like.

Description

The present invention relates to prostaglandin analogs for which the essential material constituting a disclosure thereof is incorporated by reference here from U.S. Pat. No. 4,013,695, issued Mar. 22, 1977.
