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
发明人:JEWETT MICHAEL CHRISTOPHER; STARK JESSICA CAROL; DELISA MATTHEW P; JAROENTOMEECHAI THAPAKORN
权利人:UNIV NORTHWESTERN; UNIV CORNELL
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 :Methods for the synthesis of α- hydroxy-β-amino acid and amide derivatives
发明人:SEMPLE JOSEPH E; LEVY ODILE E
权利人:CORVAS INT INC
摘要:Methods for the synthesis of alpha-hydroxy-beta-amino acid and amide derivatives and alpha-ketoamide derivatives and novel derivatives made by these methods are provided. These methods involve reacting a N-terminally blocked (protected) aminoaldehyde with an isonitrile and a carboxylic acid to give an amino-alpha-acyloxy carboxamide. The acyloxy group may be removed to give the derivative. Alternatively the protecting group is removed and acyl shift occurs to give the derivative. These derivatives are useful in the synthesis of compounds such as peptidyl alpha-ketoamides and alpha-hydroxy-beta-carboxylic acid and amide derivatives. Certain of these compounds have been reported to have activity as inhibitors of proteases, such as serine proteases and cysteine proteases.
