专利号:WO-9612008-A1 优先权日:1994-10-13 标 题 :Synthesis of methylase-resistant genes 发明人:SKOPEK THOMAS R 权利人:MERCK & CO INC; SKOPEK THOMAS R 摘要:There is disclosed a method for the synthesis of methylase-resistant genes. The method involves making specific alterations in the coding sequence of a given gene which destroys methylase recognition sequences without altering the original gene coding information. There are also disclosed new genes, designated mrkI-mrkIX, which have been synthesized to illustrate the method.
专利号:US-2008145899-A1 优先权日:2004-09-17 标题 :Production of Oligosaccharides By Microorganisms 发明人:JOHNSON KARL; BYRNE NOEL J; DEFREES SHAWN 权利人:NEOSE TECHNOLOGIES INC 摘要:The present invention relates to the enzymatic synthesis of oligosaccharides, including sialylated product saccharides. In particular, it relates to the use of recombinant cells to take up low cost precursors such as glucose, pyruvate and N-actyl-glucosamine, and to synthesize activated sugar moieties that are used in oligosaccharide synthesis. The methods make possible the synthesis of many oligosaccharides using microorganisms and readily available, relatively inexpensive starting materials.
专利号:US-6015808-A 优先权日:1993-08-20 标 题 :Synthesis of pharmaceutical compositions with lactams and β-lactams/oxo thia azabicyclo compounds 发明人:THIRUMALACHAR MANDAYAM JEERSAN; NARASIMHAN JR MANDAYAM JEERSAN 摘要:Pharmaceutical compositions with heretofore unknown and enhanced physical, chemical, and biological properties are prepared by combining known biologically active parent compounds with oxo thia azabicyclo compounds, such as lactam and beta -lactam compounds, capable of rapidly transporting the parent compounds in undegraded form to their target sites of action. A process for combining the parent compound with beta -lactam compounds consists of dissolving the parent compound in a polar solvent, adding a beta -lactam compound, incubating the resulting mixture, followed by drying, and subjecting the remaining solid material to solvent washing or extraction to further purify the new pharmaceutical composition. The new pharmaceutical composition possesses the biological and therapeutic activity of the parent compound and the barrier penetrating characteristics of the beta -lactam compound, which results in improved pharmacodynamics, including bioavailability, and an improved chemotherapeutic index, such that lower amounts of the parent may be used to avoid the toxic effects of the parent compound. Some of the new pharmaceutical compounds provide for the first time parent compounds in an orally administerable form.
专利号:US-6951958-B1 优先权日:1999-08-03 标题:Solid phase parallel synthesis of tertiary amines 发明人:ANDERSSON CARL-MAGNUS A; GUSTAFSSON MAGNUS; OLSSON KENT R I 权利人:ACADIA PHARM INC 摘要:Described is method for preparing tertiary amines comprising sequential, exhaustive alkylation of a hydroxylamine derivative and cleavage of the O—N bond using the following steps:n a) reacting the hydroxylamine derivative with an alkylating agent or with a carbonyl compound to form an oxime intermediate. b) reacting the oxime intermediate with a reducing agent to produce an alkylated derivative c) reacting the alkylated derivative with an alkylating agent or a carbonyl compound in the presence of a reducing agent to produce a dialkylated derivative d) reacting the dialkylated derivative with an alkylating agent to produce a quaternized derivative e) reacting the quaternized derivative with a reagent causing cleavage of the O—N bond to produce a tertiary amine.
