The provided liraglutide synthesis method effectively restrains or reduces the generation of racemization impurity D-Thr 5 highly similar to a product property, which facilitates the purification of the coarse liraglutide, and the high yield of the liraglutide is ensured, thereby greatly reducing production costs; during the synthesis of the liraglutide, the syntheses between dipeptide fragments, tripeptide fragments, the tetrapeptide fragments and pentapeptide fragments and the Gly-resin or the syntheses between the combination of the dipeptide fragments, the tripeptide fragments, the tetrapeptide fragments and pentapeptide fragments and the Gly resin can be carried out at the same time, and accordingly the synthesis time is shortened to some extent.
专利号:US-8227571-B2 优先权日:2007-12-11 标题 :Insulinotropic peptide synthesis using solid and solution phase combination techniques 发明人:CHEN LIN; HAN YEUN-KWEI; ROBERTS CHRISTOPHER R 权利人:CHEN LIN; HAN YEUN-KWEI; ROBERTS CHRISTOPHER R; ROCHE PALO ALTO LLC 摘要:The present invention relates to the preparation of insulinotropic peptides that are synthesized using a solid and solution phase (“hybridâ€?) 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 the third fragment which is then coupled to the second fragment and then the first fragment in solution. Alternatively, a different second fragment is coupled to the first fragment in the solid phase. Then, solution phase chemistry is then used to add additional amino acid material to a different third fragment. Subsequently, this different third fragment is coupled to the coupled first and different second fragment in the 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 the other fragments. The present invention is very useful for forming insulinotropic peptides such as GLP-1(7-36) and its natural and non-natural counteparts.
