title: Luteolytic prostaglandins. Synthesis and biological activity.
abstract: Analogues of PGF2 alpha with enhanced luteolytic activity were synthesized using the Corey synthesis. The luteolytic activity of the new prostaglandins was tested in the hamster. In addition the smooth muscle activity of the new compounds was compared with that of PGA2 on the longitudinal strip of rat stomach fundus. Structure-activity relationships in the new series of 17,18,19,20-tetranor-16-thienyl-oxy-PGF2 alpha are discussed.
