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.

摘要:The present invention provides for novel synthetic approach of solid phase synthesis of peptides with C-terminal Aspartic acid by anchoring the side chain carboxylic group of aspartic acid to the solid support to avoid the formation of various impurities and thus resulting in higher yield and ease the purification process. The present invention further provides the usage of free amino acids and reducing agents as antioxidants in the cleavage cocktail to negate the formation of oxidative impurities formed during the global cleavage and isolation of the peptide from solid support.

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.
