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.

Abstract: A method for in vitro screening a group of test substances for a ligand using two assay systems, i.e. a cellular or tissue assay system and an enzymatic assay system, is described. First, those test substances are selected which have transcriptional ER-mediated activity measured by an ER-driven reporter gene in the cellular or tissue assay system with an EC50(ER)(half-maximally effective ligand concentration) lower than or equal to 10 nmol/l. Then in an enzymatic assay system the selected test substances having the required transcriptional ER-mediated activity are tested by measuring a physical-chemical interaction (recruitment) of SRC-1 and the ER in the presence of the test substances. The selected ligand activates the ER and induces interaction with the co-present SRC-1 with an E50(ER+SRC) higher than or equal to 100 nmol/l.

Abstract: The present invention relates to novel glucocorticoid receptor antagonists for producing a drug for the prophylaxis and therapy of glucocorticoid-mediated hypogonadism, sexual dysfunctions and/or infertility.

Abstract: The present invention relates to the use of progesterone or a progesterone receptor agonist for the inhibition of steroid synthesis, in particular for inhibiting the expression of the steroidogenic acute regulatory protein (StAR protein).

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.

Abstract: This invention describes the new 8&bgr;-substituted estratrienes of general formula I in which R2, R3, R6, R6′, R7, R7′, R9, R11, R11′, R12, R14, R15, R15′, R16, R16′, R17 and R17′ have the meanings that are indicated in the description, and R8 means a straight-chain or branched-chain, optionally partially or completely halogenated alkyl or alkenyl radical with up to 5 carbon atoms, an ethinyl- or prop-1-inyl radical, as pharmaceutical active ingredients that have in vitro a higher affinity to estrogen receptor preparations of rat prostates than to estrogen receptor preparations of rat uteri and in vivo preferably a preferential action on bone rather than the uterus and/or a pronounced action with respect to stimulation of the expression of 5HT2a-receptors and 5HT2a-transporters, their production, their therapeutic use and pharmaceutical dispensing forms that contain the new compounds.

Abstract: A method of an in vitro screening for a ligand using two assay systems i.e. in a first cellular or tissue assay system, selecting the ligand with transcriptional ER-mediated activity measured by an ER-driven reporter gene, whereby in the first assay system the ligand activates the potency with an EC50(ER) (half-maximally effective ligand concentration) lower than to 10 nmol/l, and, in a second enzymatic assay system, selecting the physical-chemical interaction (recruitment) of SRC-1, wherein the ligand activates the ER and induces interaction with the co-present SRC-1 with an EC50(ER+SRC) higher than to 100 nmol/l.

Abstract: Pharmaceutical preparations containing selected steroid compounds and methods of treating estrogen deficiency in the central nervous system (CNS) without influencing other organs or systems are described. These steroids have selective neurotropic estrogen-like transcription action in contrast to the systemically acting natural and synthetic estrogen compounds, such as 17&agr;-estradiol. The selected steroids surprisingly have a selective influence on the transcription estrogen-dependent gene in the CNS and cause changes of physiological parameters as well as CNS-specific transcription effects in the dosages used with no biological effects in reproductive system tissues. They have CNS specific transcription effects at those dosages at which neither 17 &bgr;-estradiol nor 17&agr;-estradiol had any action and the transcription estrogen-dependent gene in the CNS is not influenced by secondarily formed 17&bgr;-estradiol.
