New 11β-aryl-substituted steroids exhibit both progestational and antiprogestational activity

The syntheses of three 11β-aryl-19-norpregna-4,9-dien-3-one derivatives with 17-spirolactone and 17β-hydroxy-17α-cyanoethyl substitutions are described. The progesterone agonist/antagonist activities of the new compounds are investigated using a recently
