Diastereoisomers of 3,17β-dihydroxy-20,21-epoxy-19-norpregna-1,3,5-(10)-triene have been prepared as potential antitumor agents.Both isomers undergo the base-catalyzed Payne rearrangement.The isomers were cytotoxic to mammalian cells in culture and were able to displace <3H>estradiol from binding sites in rat uterine cytosols with 1/7 and 1/70 the potency of estradiol.The reasons for this difference are discussed.
