    摘要: The invention provides methods of obtaining a peptide that include steps of synthesizing a peptide intermediate having one or more side chain protecting groups; providing a solvent to the peptide intermediate to form a peptide intermediate composition; and providing a precipitating agent in an amount sufficient to precipitate the peptide intermediate from the peptide intermediate composition, wherein the precipitating agent is an alcohol having three or more carbon atoms. Also provided are methods for precipitating peptides, methods for concentration peptides, and methods for filtering peptides.

    摘要: The present invention relates to the preparation of insulinotropic peptides that are synthesized using a solid and solution phase (“hybrid”) approach. Generally, the approach includes synthesizing three different peptide intermediate fragments using solid phase chemistry. Solution phase chemistry is then used to add additional amino acid material to one of the fragments. The fragments are then coupled together in the solid solution phase. The use of a pseudoproline in one of the fragments eases solid phase synthesis of that fragment and also eases subsequent solution phase coupling of this fragment to other fragments. The present invention is very useful for forming insulinotropic peptides such as GLP-1(7-36) and its natural and non-natural counterparts.
