专利号:US-2008287407-A1 优先权日:2003-12-10 标题 :Nitric Oxide Releasing Pyruvate Compounds, Compositions and Methods of Use 发明人:GARVEY DAVID S; FANG XINQIN; KHANAPURE SUBHASH P; RANATUNGA RAMANI R; WEY SHIOW-JYI 权利人:NITROMED INC 摘要:The invention describes novel nitrosated and/or nitrosylated pyruvate compounds and pharmaceutically acceptable salts thereof, and novel compositions comprising at least one nitrosated and/or nitrosylated pyruvate compound, and, optionally, at least one compound that donates, transfers or releases nitric oxide, stimulates endogenous synthesis of nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor or is a substrate for nitric oxide synthase, and/or at least one therapeutic agent. The invention also provides novel compositions comprising at least one pyruvate compound and at least one compound that donates, transfers or releases nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor, stimulates endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase and/or at least one therapeutic agent. The invention also provides novel kits comprising at least one pyruvate compound, that is optionally nitrosated and/or nitrosylated, and, optionally, at least one nitric oxide donor and/or at least one therapeutic agent. The invention also provides methods for treating diseases resulting from oxidative stress, diabetes, reperfusion injury following ischemia, preservation of tissues, organs, organ parts and/or limbs.
专利号:US-4461726-A 优先权日:1982-05-17 标题 :Desulfurization of penicillins to prepare azetidinones 发明人:WEI CHUNG-CHEN; WEIGELE MANFRED 权利人:HOFFMANN LA ROCHE 摘要:A process for the Raney nickel desulfurization of penicillins is described. In the process of the invention, amino penicillanic acid or derivatives thereof are reacted with Raney nickel under controlled conditions of temperature and time to yield azetidinones which are useful as intermediates for the synthesis of monocyclic beta-lactam antibiotics.
