标题 :Compositions and methods for rapid in vitro synthesis of bioconjugate vaccines in vitro via production and N-glycosylation of protein carriers in detoxified prokaryotic cell lysates

摘要:Disclosed are methods, systems, components, and compositions for cell-free synthesis of glycosylated carrier proteins. The glycosylated carrier proteins may be utilized in vaccines, including anti-bacterial vaccines. The glycosylated carrier proteins may include a bacterial polysaccharide conjugated to a carrier, which may be utilized to generate an immune response in an immunized host against the polysaccharide conjugated to the carrier. The glycosylated carrier proteins may be synthesized in cell-free glycoprotein synthesis (CFGpS) systems using prokaryote cell lysates that are enriched in components for glycoprotein synthesis such as oligosaccharyltransferases (OSTs) and lipid-linked oligosaccharides (LLOs) including OSTs and LLOs associated with synthesis of bacterial O antigens.

标 题 :Synthesis of cyclic amidines

权利人:LENTZEN GEORG; NEUHAUS THORSTEN; BITOP AG
摘要:The invention relates to an innovative method for synthesis of cyclic amidines. The synthesis starts from a β-, γ- or δ-lactone which is twofold brominated. After esterification of the carboxyl function, the bromine atoms are nucleophilically substituted and the corresponding diamino compound is obtained. The ring closure to the cyclic amidine is accomplished subsequently by reaction with orthoester, imidate or thioimidate. Owing to interposing additional steps for recovery of the diamino compound in enantiomerically pure form, the enantiomers of the cyclic amidines can be stereoselectively synthesized.

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.

摘要:Provided herein are products and processes for efficiently synthesizing biomolecules in vitro using cell-free extracts derived from mammalian cells and insect cells. In an embodiment, provided is a process for preparing a cell-free extract from insect cells and mammalian cells that efficiently synthesizes post-translationally modified target proteins (e.g., glycosylated target proteins). In some embodiments, a ribonucleic acid is synthesized in vitro that comprises a cap, a 5′ untranslated region comprising an 18S rRNA binding ribonucleotide sequence, and a target ribonucleotide sequence. It has been determined that such ribonucleic acids result in efficient in vitro synthesis of a target protein using cell-free extracts derived from non-rabbit mammalian cells and insect cells.
