title: Synthesis and biological evaluation of 10-oxa-11-deoxyprostaglandin E1 and 10-nor-9,11-secoprostaglandin F1 and their derivatives.
abstract: Three 10-oxa-11-deoxyprostaglandin E1 and two 10-nor-9,11-secoprostaglandin F1 analogues were prepared. The compounds were evaluated for pregnancy interruptions, oxytocin-like activity (uterine strip), and antiprostaglandin activity. One of the 10-nor-9,11-secoprostaglandin F1 analogues displayed activity as a PGE2 antagonist in the gerbil colon smooth muscle preparation.
