  • Patent number: 7473709
    Abstract: The present patent application relates to 11?-benzaldoxime derivatives of D-homooestra-4,9-dien-3-ones of formula I: wherein R1 is a hydrogen atom or a C1-C6-alkyl, C1-C6-acyl, C1-C4-alkoxycarbonyl, C1-C4-alkylthiocarbonyl, C1-C6-alkylaminocarbonyl or arylaminocarbonyl group; and R2 is a hydrogen atom or a C1-C6-alkyl or C1-C6-acyl group. Compounds of formula I bind more strongly to the glucocorticoid receptor than to the progesterone receptor and are effective antiglucocorticoids. According to the invention, they are suitable for the treatment and/or prevention of symptoms and/or diseases that are attributable to an androgen deficiency induced by glucocorticoids, especially cortisol.

  • Patent number: 7250408
    Abstract: The novel glucocorticoid receptor antagonists are 11?-substituted steroid compounds of formula (I): wherein R1 denotes a methyl group, a methoxy group, or an ethoxy group; wherein R2 denotes a tert.-butyl group, a 1-hydroxy-1-methylethyl group, a 1-methoxy-1-methylethyl group, an ethyl isocrotonate group, or a substituted phenyl group. The method of treating an individual suffering from glucocorticoid-mediated hypogonadism, sexual dysfunctions, and/or infertility includes administering a daily dosage consisting of an effective amount of one of these 11?-substituted steroid compounds.

  • Publication number: 20070078091
    Abstract: This invention relates to pharmaceutical combinations for compensating for an absolute and relative testosterone deficiency in men with simultaneous prophylaxis for the development of a benign prostatic hyperplasia (BPH) or prostate cancer. The combinations according to the invention contain a natural or synthetic androgen in combination with a gestagen, an antigestagen, an antiestrogen, a GnRH analog, a testosterone-5?-reductase inhibitor, an ?-andreno-receptor blocker or a phosphodiesterase inhibitor. In comparison to the combinations according to the invention, any active ingredient by itself cannot achieve the desired goal.

  • Publication number: 20070010514
    Abstract: The present invention relates to non-steroidal progesterone receptor modulators of the general formula I, a process for their preparation, the use of the progesterone receptor modulators for producing medicaments, and pharmaceutical compositions comprising these compounds. The compounds according to the invention are suitable for the therapy and prophylaxis of gynaecological disorders such as endometriosis, leiomyomas of the uterus, dysfunctional bleeding and dysmenorrhoea, and for the therapy and prophylaxis of hormone-dependent tumours and for use for female fertility control and for hormone replacement therapy.

  • Patent number: 6670493
    Abstract: The method of treating or preventing a disease in a human male or a male animal caused by a decreased production of androgens, such as testosterone, in the human male or male animal includes administering an effective amount of a glucocorticoid receptor antagonist to the human male or the male animal in order to increase production of the androgens. These diseases include male sexual dysfunction, infertility and hypogonadism. Novel androgen receptor antagonist compounds and methods of synthesis are also described.
