摘要:
The present invention provides mutant proteins of steroid hormone receptors. These mutant proteins are useful in methods of distinguishing a steroid hormone receptor antagonist from a steroid hormone receptor agonist. The present invention also provides plasmids containing mutated steroid hormone receptor proteins and cells transfected with those plasmids. In addition, the present invention provides methods for determining whether a compound is a steroid hormone receptor antagonist or agonist. Also, the present invention provides methods of determining endogenous ligands for steroid hormone receptors. The invention further provides a molecular switch for regulating expression in gene therapy.
摘要:
This invention provides methods and combination formulations and kits to reduce the toxicity of camptothecin drugs, such as irinotecan (CPT-11). Disclosed are therapeutics and treatment methods employing such drugs in combination with agents that increase conjugative enzyme activity or glucuronosyltransferase activity, and agents that decrease biliary transport protein activity, such as cyclosporine A, the resultant effects of which are to decrease the significant side effects previously associated with treatment using these drugs.
摘要:
A method for treating an individual exposed to or infected with HIV is disclosed which comprises administering to said individual a therapeutically effective amount of one or more compounds which inhibit or prevent replication of said HIV by interfering with the replicative or other essential functions of vpr expressed by said HIV, by interactively blocking the vpr target in human cells, and thereby preventing translocation of the vpr/target complex from the cytosol of said human cells to the nuclei of said cells, where vpr carries on activities essential to replication of HIV. In preferred embodiments, the compound or compounds which interactively block the target are steroid hormone receptor antagonists, glucocorticoid receptor antagonists, or glucocorticoid receptor Type II antagonists, especially mifepristone (RU-486). Pharmaceutical compositions comprising these compounds, as well as a method for identifying them and a kit for use therein, are also disclosed.
摘要:
Competitive progesterone antagonists, including two novel steroids, viz., 11β,19-[4-(cyanophenyl)-o-phenylene]-17β-hydroxy-17α-(3-hydroxyprop-1(Z)-enyl)-4-androsten-3-one and 11β,19-[4-(3-pyridinyl)-o-phenylene]-17β-hydroxy-17α-(3-hydroxyprop-1(Z)-enyl)-4-androsten-3-one, inhibit formation of endometrial glands at below their ovulation inhibiting dose and the abortive dose, and thus achieve oral contraception in females without adversely affecting the menstrual cycle and without risk of aborting a previous implanted fertilized egg or a fetus.
摘要:
Fertilization of an oocyte is prevented or inhibited by administering a fertilizing inhibitory amount of an antiprogestin to an ovulatory mammal in an amount which is insufficient to prevent ovulation but sufficient to inhibit fertilization, while the regularity of the menstrual cycle is sustained.

L'invention a pour objet l'utilisation de composés anti-progestomimétiques pour la fabrication de compositions pharmaceutiques destinées à favoriser l'ovulation.
摘要:
Die vorliegende Erfindung betrifft ein pharmazeutisches Kombinationspräparat zur Weheninduktion bzw. zur Verhinderung des Eintretens einer Schwangerschaft, enthaltend A) ein oder mehrere Antigestagen(e) B) eine oder mehrere langkettige polyungesättigte Fettsäure(n) bzw. deren Zubereitungen und, falls erforderlich C) Prostaglandine, wobei als Antigestagene alle Verbindungen in Frage kommen, die eine starke Affinität zum Gestagenrezeptor besitzen, dabei aber selbst keine nennenswerte eigene gestagene Aktivität zeigen. Die Präparate werden bevorzugt intravaginal oder (extra)-amnial appliziert. Dabei können die Antigestagene und die erfindungsgemäßen Fettsäuren entweder gleichzeitig oder getrennt, z.B. nacheinander verabreicht werden.
摘要:
A method for treating endogenous, painful gastrointestinal condition of non-inflammatory, non-ulcerative origin, such as abdominal migraine and irritable bowel syndrome, entails administering a pharmacologically effective amount of a mast cell degranulation-blocking agent, e.g. a histamine-3 receptor agonist.
