摘要:
Oxytocin receptor antagonists of formula (1) wherein R12 is hydrogen, alkoxycarbonyl or unsubstituted or substituted alkyl; R13 is hydrogen, alkoxyl, aralkoxyl, alkoxycarbonyl, alkoxycarbonylamino, unsubstituted or substituted cycloalkyl, unsubstituted or substituted phenyl, unsubstituted or substituted amino, unsubstituted or substituted rings of formulae (2-17) or unsubstituted or substituted alkyl, and the pharmaceutically acceptable salts thereof, are useful for increasing fertility rates and embryonic survival in farm animals. The compounds are also useful for improving survival rates of farm animal neonates by controlling the timing of parturition to effect delivery of the neonates during daylight hours, thereby ensuring proper monitoring of the neonates. Additionally, the compounds are useful for controlling the timing of estrus.
摘要:
The combination of the HIV protease inhibitor Compound J and one or more of nevarapine or an α-APA derivative is useful in theinhibition of HIV protease, the inhibition of HIV reverse transcriptase, the prevention or treatment of infection by HIV and the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in combination with other antivirals, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by HIV are also described.
摘要:
A process for racemization of optically pure or enriched piperazine-2-tert-butylcarboxamide and its derivatives comprising reacting the optically pure or enriched piperazine compound with a racemizing agent selected from a strong base, an anhydrous metal salt or a carboxylic acid, in a solvent at a temperature range of between room temperature and 250 °C. The piperazine carboxamide derivatives are key intermediates in the preparation of HIV protease inhibitor compounds, including Compound J.
摘要:
The invention encompasses the novel compound of Formula (I) useful in the treatment of cyclooxygenase-2 mediated diseases. The invention also encompasses certain pharmaceutical compositions for treatment of cyclooxygenase-2 mediated diseases comprising compounds of Formula (I).
摘要:
Compounds of formula (I), where R?1 and R2¿ are independently hydrogen or optionally-substituted C¿1-4?alkyl or aryl, and R?1¿ also forms a heterocycle or heterocycle-C¿1-4?alkyl, are HIV protease inhibitors. These compounds are useful in the prevention or treatment of infection by HIV and in the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in combination with other antivirals, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by HIV are also described.
摘要:
Fibrinogen receptor antagonists of formula (I) are disclosed for use in inhibiting the binding of fibrinogen to blood platelets and for inhibiting the aggregation of blood platelets, for example (A).
摘要:
Novel carboxy-peptidyl compounds of formula (I) are found to be useful inhibitors of matrix metalloendoproteinase-mediated diseases including osteoarthritis, rheumatoid arthritis, septic arthritis, tumor invasion in certain cancers, periodontal disease, corneal ulceration, proteinuria, dystrophobic epidermolysis bullosa, coronary thrombosis associated with atherosclerotic plaque rupture, and aneurysmal aortic disease. The matrix metalloendoproteinases are a family of zinc-containing proteinases including but not limited to stromelysin, collagenase, and gelatinase, that are capable of degrading the major components of articular cartilage and basement membranes. The inhibitors claimed herein may also be useful in preventing the pathological sequelae following a traumatic injury that could lead to a permanent disability. These compounds may also have utility as a means for birth control by preventing ovulation or implantation.
