  • Patent number: 7169769
    Abstract: This invention relates to steroidal compounds having the formula I wherein: R1 is O, (H,H), (H,OH), NOH, whereby OH is optionally etherified or esterified; R2 and R3 are independently hydrogen or (C1-4) alkyl and at least one of R2 and R3 is (C1-4) alkyl; R4 is hydrogen, or (C1-15) acyl for use in androgen-related treatments, such as androgen insufficiency and male or female contraception.

  • Patent number: 6949531
    Abstract: Disclosed are androgenic steroids of the (14?,17?)-17-(hydroxymethyl) type. The invention relates to an improvement thereof, which is based on the presence of a ?-oriented, annellated cyclopropyl group which includes carbon atoms 16 and 17 of the steroid skeleton, i.e. a 16,17?-methylene moiety. These steroids show an unexpectedly high androgenic potency.
