Curator's Comment: description was created based on several sources, including, http://www.ncbi.nlm.nih.gov/pubmed/3023306,

Epitiostanol is androgenic antiestrogen developed for the treatment of breast cancer. The drug inhibits estrogen receptor and activates androgen receptor and was shown to be active in vitro on MCF-7, U-2 and U-3 cells. The current marketing status of Epitiostanol is unknown and is supposed to be "discontimued".
