title: A new selective antagonist of prostaglandins: 20-methyl-13,14-didehydro-PGF2 alpha.
abstract: 20-methyl-13,14-didehydro-PGF2 alpha has been assayed for antagonistic activity against PGF2 alpha and PGE2 on different smooth msucle preparations in vitro. This compound may be considered a selective and probably a competitive antagonist of PGF2 alpha on rat uterus in vitro.
