The present invention provides a manufacturing process for preparing a peptide, preferably a decapeptide, such as degarelix, by incorporating p-nitro-phenylalanin in the amino acid sequence preferably during stepwise solid phase synthesis, and converting these into the required amino acids Aph(Hor) and/or D-Aph(Cbm), preferably while attached to a solid phase. The invention further provides intermediates useful in the manufacturing process.
本发明提供了一种制备多肽(最好是十肽,如 degarelix)的生产工艺,其方法是在氨基酸序列中(最好是在分步固相合成过程中)加入对硝基苯丙氨酸,并将其转化为所需的氨基酸 Aph(Hor)和/或 D-Aph(Cbm),最好是在附着于固相的同时进行。本发明进一步提供了生产过程中有用的中间体。
