摘要:Disclosed is synthesis of an O-Antigen oligosaccharide compound of Helicobacter pylori serotype O2, belonging to the field of organic synthesis. The disclosure obtains O-antigen disaccharide to tetracosasaccharide of Helicobacter pylori serotype O 2 by chemical synthesis. A chemical synthesis method which is quite conducive to production of a glucose-α-lglucosidic bond is developed in the disclosure by a protectant strategy, temperature effect, solvent effect, and additive effect. The method is applied in synthesis of an O-antigen oligosaccharide compound of Helicobacter pylori serotype O2 assembled with an amino linking arm. A saccharide conjugate can be prepared from the synthesized O-antigen oligosaccharide compound of Helicobacter pylori serotype O2 assembled with an amino linking arm together with a carrier protein for immunology researches, playing an important role in preventing and treating Helicobacter pylori.

标题 :Synthesis of cyclic peptides

摘要:This invention relates to methods for preparing cyclic peptides and peptidomimetic compounds in solution and bound to solid supports, and to cyclic peptide or peptidomimetic libraries for use in drug screening programs. In particular, the invention relates to a generic strategy for synthesis of cyclic peptides or peptidomimetics that enables the efficient synthesis under mild conditions of a wide variety of desired compounds. Two approaches were evaluated for their improvements in solution and solid phase synthesis of small cyclic peptides: positioning reversible N-amide substituents in the sequence; and applying native ligation chemistry in an intramolecular sense. Systematic investigation of the effects of preorganising peptides prior to cyclisation by using peptide cyclisation auxiliaries, and developing new linkers and peptide cyclisation auxiliaries to aid cyclic peptide synthesis gives surprising improvements in both yields and purity of products compared to the prior art methods. The combination of these technologies provides a powerful generic approach for the solution and solid phase synthesis of small cyclic peptides. The ring contraction and N-amide substitution technology of the invention provide improved methods for the synthesis of cyclic peptides and peptidomimetics. When used in conjunction with linker strategies, this combination provides solid-phase avenues to cyclic peptides and peptidomimetics.

摘要:The present invention relates to non-naturally occurring polypeptides useful for preparing armodafinil, polynucleotides encoding the polypeptides, and methods of using the polypeptides. The non-naturally occurring polypeptides of the present invention are effective in carrying out biocatalytic conversion of the (i) 2-(benzhydrylsulfinyl)acetamide to (−)-2-[(R)-(diphenylmethyl)sulfinyl]acetamide (armodafinil), or (ii) benzhydryl-thioacetic acid to (R)-2-(benzhydrylsulfinyl)acetic acid, which is a pivotal intermediate in the synthesis of armodafinil, in enantiomeric excess.
