developed a mixed-phase synthesis, which included production of fragments through solid-phase peptide synthesis, followed by an assembly of these fragments in solution. We were able to show that this new process delivered the desired peptide moiety in gram-scale with high purity. The overall yield was improved from 1 % for the sequential solid-phase process to 9 % for the fragment synthesis. Finally, a PEGylation
在给定的手稿中,我们总结了我们为聚乙二醇化肽开发可扩展合成的活动,该肽经历了代谢紊乱的发展。该多肽包含 31 个天然氨基酸序列,并在 C 端进行位点特异性聚乙二醇化。最初的合成研究表明,目标分子的肽部分不是线性固相过程的理想目标,因为我们面临着“困难的序列”,这导致了低产率的过程。随后,我们开发了一种混合相合成,包括通过固相肽合成产生片段,然后在溶液中组装这些片段。我们能够证明这种新工艺以高纯度提供了克级规模的所需肽部分。总产率从顺序固相工艺的 1% 提高到片段合成的 9%。最后,安装了聚乙二醇化工艺以提供用于临床前和临床测试的原料药。(© Wiley-VCH Verlag GmbH & Co.
