Abstract: The present invention discloses the use of ER&bgr;-selective ligands for production of medicaments for regulating fertility without additional use of a progestin. ER&bgr;-agonists are used for treatment of infertility and ER&bgr;-antagonists for contraception.

Abstract: This invention describes a 11&bgr;-long-chain-substituted estratriene of general formula (I), in which R11 is a long-chain radical that has a nitrogen atom and optionally a sulfur atom, which in addition can be functionalized in the terminal position with a perfluoroalkyl group or an optionally substituted arly radical. The compound can have antiestrogenic or tissue-selective estrogenic properties and be suitable for the production of pharmaceutical agents.

Abstract: A method of inhibiting the occurrence of advanced endometrium maturation in a female mammal undergoing fertility treatment is disclosed. The method comprises the administration at least one 17&agr;-fluoralkylated progesterone receptor antagonist to the female mammal.

Abstract: The present invention relates to a method for impairing cumulus expansion and oocyte maturation, the method comprising antagonizing EP2 receptor and/or inhibiting cyclooxygenase COX-2. The invention also relates to the use of a pharmaceutical composition comprising an EP2 receptor antagonist (optionally with one or more COX inhibitors) for female contraception.

Abstract: A novel medicament for the treatment of estrogen-deficient disease states is disclosed. Said medicament is a combination preparation comprising an ER&bgr;-selective estrogen and an ER&agr;-selective antiestrogen or SERM (Selective Estrogen Receptor Modulator). The antiestrogen or SERM which is a component of the combination preparation is preferably selective for the periphery. The preparation is suitable for an organ-specific estrogen therapy and has clear advantages over conventional therapies. Due to the combination of ER&agr;-selective SERM and ER&bgr;-estrogen the preparation permits a complete protection against bone loss caused by estrogen deficiency. The components of the medicament also have a synergistic effect with respect to the inhibition of inflammation inducing genes, in particular in inflammatory disorders such as atherosclerosis and arthritis, or neurodegenerative diseases such as Alzheimers and multiple sclerosis. Furthermore, positive effects on cognition and mood may be expected.

Abstract: This invention describes the new 4-fluoroalkyl-2H-benzopyrans of general formula I, 1

Abstract: This invention describes the new 8&bgr;-substituted estratrienes of general formula (I),

Abstract: The invention describes a combination preparation of an oestrogen and an antioestrogen, characterized in that the oestrogen is selected from the group consisting of 17-&bgr;-oestradiol, 17-&agr;-ethynyloestradiol, oestriol, oestrone, oestrone sulphate, oestrogen sulphamates, 17&agr;-oestradiol, mestranol, stilboestrol and naturally conjugated oestrogens and in that the antioestrogen is a substituted 7&agr;-(&xgr;-aminoalkyl)oestratriene of the general formula I The combination preparation according to the invention can be used for hormone substitution therapy.

Abstract: The present invention relates to non-steroidal progestins of the general formula (I) 1

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: This invention relates to 11&bgr;-(para-substituted)phenyl-estra-1,3,5(10)-trienes with a straight-chin or branched-chain, optionally partially or completely halogenated alkyl radical or alkenyl radical in each case with up to 5 carbon atoms, an ethinyl radical or prop-1-inyl radical in 8&bgr;-position.

Abstract: The present invention relates to the use of FF-MAS and/or its analogues to increase the implantation rate of preimplantational embryos.

Abstract: In vitro fertilization can be improved by adding a meiosis activating compound.

Abstract: The present invention discloses the use of ER&bgr;-selective ligands for production of medicaments for regulating fertility without additional use of a progestin.

Abstract: This invention describes the new benzocycloheptenes of general formula I 1

Abstract: Benzocycloheptenes of general formula I in which R1, R2 and Y have the meanings indicated herein, have antiestrogenic activity on and are suitable for the production of pharmaceutical agents, especially for prophylaxis and therapy of osteoporosis.

Abstract: The present invention relates to steroid compounds of general formula X, which may advantageously be employed to stimulate meiosis in human oocytes, the steroid being specifically characterized by amino nitrogen bonded to C17 of the steroid skeleton via a spacer A.

Abstract: A method of inhibiting the occurrence of advanced endometrium maturation in a female mammal undergoing fertility treatment is disclosed. The method comprises the administration at least one 17&agr;-fluoralkylated progesterone receptor antagonist to the female mammal.

Abstract: This invention describes the new benzocycloheptenes of general formula I 1

Abstract: This invention describes new, substituted 7&agr;-(&egr;-aminoalkyl)-estratrienes of general formula I in which side chain SK is a radical of partial formula The new compounds represent compounds with very strong antiestrogenic action. The compounds according to the invention are, on the one hand, pure antiestrogens, or, on the other hand, antiestrogens with estrogenic partial action. Based on this spectrum of action, the new compounds are highly suitable for the production of pharmaceutical agents for tumor therapy and hormone replacement treatment.
