专利号:US-8461357-B2 优先权日:2008-09-19 标题 :Expeditious synthesis of gibberellin A5 and esters thereof 发明人:FAIRWEATHER KELLY A; MANDER LEWIS N; PHARIS RICHARD P 权利人:FAIRWEATHER KELLY A; MANDER LEWIS N; PHARIS R P; UTI LIMITED PARTNERSHIP 摘要:An expeditious synthesis of gibberellin A 5 (GA 5 ) esters is presented, from which GA 5 may be prepared. The synthesis offers an inexpensive route of few steps to these compounds, starting from gibberellin A 3 (GA 3 ) esters in the presence of a metal hydride.
专利号:US-8058414-B2 优先权日:2008-04-29 标题 :Unnatural polymerase substrates that can sustain enzymatic synthesis of double stranded nucleic acids from a nucleic acid template and methods of use 发明人:MENCHEN STEVEN; ROSENBLUM BARNETT; KENNEY PAUL; KHAN SHOEB; MA ZHAOCHUN; CHEN JER-KANG; LAM JOE Y; HUANG BOLI 权利人:MENCHEN STEVEN; ROSENBLUM BARNETT; KENNEY PAUL; KHAN SHOEB; MA ZHAOCHUN; CHEN JER-KANG; LAM JOE Y; HUANG BOLI; LIFE TECHNOLOGIES CORP 摘要:Nucleotide analogs that can sustain the enzymatic synthesis of double-stranded nucleic acid from a nucleic template are described. The nucleotide analogs include: (i) a base selected from the group consisting of adenine, guanine, cytosine, thymine, uracil and their analogs; (ii) a label attached to the base or analog of the base via a cleavable linker; (iii) a deoxyribose; and (iv) one or more phosphate groups. The linker and/or the label inhibits template directed polymerase incorporation of a further nucleotide substrate onto an extended primer strand. In addition, cleavage of the linker leaves a residue attached to the base which is not present in the natural nucleotide and which does not inhibit extension of the primer strand. The nucleotide analogs can therefore be used as reversible terminators in sequencing by synthesis methods without blocking the 3′ hydroxyl group. Methods of sequencing DNA using the substrates are also described.
专利号:US-9085538-B2 优先权日:2010-07-26 标题:Process for the preparation of key intermediates for the synthesis of statins or pharmaceutically acceptable salts thereof 发明人:CASAR ZDENKO; STERK DAMJAN; JUKIC MARKO 权利人:CASAR ZDENKO; STERK DAMJAN; JUKIC MARKO; LEK PHARMACEUTICALS 摘要:The invention relates to commercially viable process for the synthesis of key intermediates for the preparation of statins, in particular Rosuvastatin and Pitavastatin or respective pharmaceutically acceptable salts thereof. A new simple and short synthetic route for key intermediates is presented which benefits from the use of cheap and readily available starting materials, by which the conventionally most frequently used DIBAL-H as reducing agent can be avoided.
