Abstract: The present invention relates to certain new and useful steroids which demonstrate anti-androgenic properties. These steroids are 5,10-secosteroids that have been found to be potent irreversible inhibitors of the enzyme .DELTA..sup.5 -3-ketosteroid isomerase which is involved in androgen biosynthesis. In addition, certain of the steroids of the invention compete reversibly with 5-.alpha.-dihydrotestosterone for binding to the prostatic cytoplasmic receptor protein while others inhibit the enzyme prostatic testosterone 5-.alpha.-reductase. The anti-androgenic properties of the present compounds indicate such utility as the control of abnormal growth of the human prostate, e.g. in the therapy of human prostatic cancer.
