标题:3-或5-Cf 3-吡唑的选择性,无金属方法:Cf 3-壬酮与肼的溶剂转换反应
摘要:对三氟乙酰化乙炔与芳基(烷基)肼的反应进行了详细的研究,目的在于区域选择性合成3-或5-三氟甲基化的吡唑.发现反应的区域选择性极大地取决于溶剂性质.高极性质子溶剂(六氟异丙醇)有利于3-三氟甲基吡唑的形成.相反,当反应在极性非质子溶剂(dmso)中进行时,优先观测到它们的5-Cf 3-取代的异构体的形成.或者,3-Cf 3的区域选择性组装取代的吡唑可以通过两步一锅法进行.在酸性催化剂存在下三氟甲基化的炔酮与芳基(烷基)肼的反应导致形成相应的.后者可以通过用碱处理平滑地转化为3-Cf 3-吡唑.该溶剂可切换程序用于制备重要药物,如celebrex和sc-560以及其以克为单位的异构体.讨论了可能的反应机理.

标 题 :Combinations of a cyclooxygenase-2 selective inhibitor and a TNFalpha antagonist and therapeutic uses therefor
发明人:BENNETT DENNIS A
权利人:PHARMACIA CORP
摘要:A method for the prevention, treatment, or inhibition of pain, inflammation, or inflammation-related disorder and for the prevention, treatment, or inhibition of a cardiovascular disease or disorder in a subject that is in need of such prevention, treatment or inhibition, involves the administration to the subject of a cyclooxygenase-2 selective inhibitor or prodrug thereof and a TNFα antagonist. A method can also involve the treatment, prevention, or inhibition of cancer in a subject in need of such treatment, prevention, or inhibition, by administering to the subject a cyclooxygenase-2 selective inhibitor or prodrug thereof and a TNFα antagonist which is selected from the group consisting of a compound that affects the synthesis of TNFα, a compound that inhibits the binding of TNFα with a receptor specific for TNFα, and a compound that interferes with intracellular signaling triggered by TNFα binding with a receptor. Compositions, pharmaceutical compositions and kits that can be used with the methods are also described.

标 题 :Cyclooxygenase-2 inhibition
发明人:DANNENBERG ANDREW J
权利人:CORNELL RES FOUNDATION INC
摘要:Selective inhibitors of cyclooxygenase-2 are used to treat liver disease and in combination with anti-viral drugs to treat virus-caused liver disorders. Selective inhibitors of cyclooxygenase-2 which also inhibit the synthesis of cyclooxygenase-2 improve over the efficacy of conventional selective inhibitors of cyclooxygenase-2 in the treatment of inflammatory conditions, Alzheimer's disease and cancer.
