摘要:The present invention provides: a polyphosphorylated nucleoside which has a structure represented by formula (I) and can be efficiently produced by a short process and a simple operation with use of a less expensive material; a phosphate-activated nucleotide which is used for the synthesis of the polyphosphorylated nucleoside and a method for the synthesis of this phosphate-activated nucleotide; and a method for the synthesis of a polyphosphorylated nucleoside using a phosphate-activated nucleotide. In the formula, B represents a protected or unprotected, natural or artificial nucleoside base; R 1 , R 2 , R 4 and R 5 each represent H or an alkyl group or the like, and R 1 , R 2 , R 4 and R 5 may be the same as or different from each other; X and Y each represents H, OH, OCH 3 or the like; h represents an integer of 1 to 3; p, n, m and q each represent 0 or an integer, and p, n, m and q are in no particular order; and (p + n + m + q) is an integer of 0 to 5,000.

标 题 :Synthesis of human virus antigens by yeast

摘要:The present invention relates to synthesis of HB S Ag in yeast. Yeast expression vectors comprising a yeast promoter, ADH1, have been constructed. The region of the HBV genome coding for the S-protein, excluding a possible 163 amino acid presequence, has been transferred to the yeast expression vector. Using the described yeast vector, the successful synthesis of HB S Ag by yeast has been achieved. The product is antigenic (reactive with anti-HB S Ag), and a substantial portion is found associated with particles identical in electron microscopic appearance to those found in the serum of HBV-infected patients and in Alexander cells but having a smaller particle size diameter. The HB S Ag synthesized by yeast has identical sedimentation behavior to purified, naturally occurring HB S Ag particles purified from Alexander cells as measured by sucrose gradient sedimentation. The present invention demonstrates synthesis and assembly of a higher ordered multi-component structure resulting from expression of a heterologous DNA coding segment in a microorganism.

摘要:The present invention relates to synthesis of HBsAg in yeast. Yeast expression vectors comprising a yeast promoter, ADHI, have been constructed. The region of the HBV genome coding for the S-protein, excluding a possible 163 amino acid presequence, has been transferred to the yeast expression vector. Using the described yeast vector, the successful synthesis of HBsAg by yeast has been achieved. The product is antigenic (reactive with anti-HBsAg), and a substantial portion is found associated with particles identical in electron microscopic appearance to those found in the serum of HBV-infected patients and in Alexander cells but having a smaller particle size diameter. The HBsAg synthesized by yeast has identical sedimentation behavior to purified, naturally-occurring HBsAg particles purified from Alexander cells as measured by sucrose gradient sedimentation.

权利人:US NAVY
摘要:The method described herein allows for melt stabilization and vapor-phase synthesis of a cesium germanium halide utilizing germanium dihalides formed in situ. This disclosure allows for the melting of cesium germanium halides without decomposition, which allows for growing crystals of these materials from the melt. This disclosure allows for a direct synthesis of these materials without the use of water or the introduction of other possible contaminants.

标 题:Bromine-facilitated synthesis of fluoro-sulfur compounds
发明人：WINTER ROLF
权利人:AVANTBIO CORP
摘要:Described herein are methods for the bromine-facilitated synthesis of fluoro-sulfur compounds, that include SF 4 , SF 5 Cl, SF 5 Br and SF 6 . The methods described herein generally require lower temperature and pressure, produce higher yields, require less time, do not use corrosive or costly reactants and solvents that are commonly used in the synthesis of the fluoro-sulfur compounds, and do not produce deleterious waste products when compared to previously-used methods.
