The present invention relates to a novel acylating agent, a method for its preparation, and a method of using it for acylating one or more amino groups of an amino acid, a peptide, or a protein. The novel acylating agent may be a compound which comprises a structural element -HN-(CH2)2-(O-((CH2)2)k-O-(CH2)n-CO-, wherein k is an integer in the range of 1-10, and n is an integer in the range of 1-2, being esterified at its -CO-end to the hydroxy group of 3,5-dichloro-2-hydroxy-benzenesulfonic acid (3,5-DC-2-HBSA). This novel acylating agent has an improved stability. Using this agent the acylation process is improved as regards robustness, as well as improving yield and overall production economy. The novel acylating agent is useful for acylating pharmaceutical peptides and proteins such as GLP-1, insulin, pYY, and amylin. The invention also relates to a number of novel GLP-1 precursor peptides and derivatives in which the two N-terminal amino acids have been deleted.
本发明涉及一种新型酰化试剂,其制备方法以及用于酰化氨基酸、肽或蛋白质中的一个或多个氨基的方法。这种新型酰化试剂可以是一种包含结构元素-HN-(CH2)2-(O-((CH2)2)k-O-(CH2)n-CO-的化合物,其中k为1-10范围内的整数,n为1-2范围内的整数,在其-CO端酯化为3,5-二氯-2-羟基苯磺酸(3,5-DC-2-HBSA)的羟基。这种新型酰化试剂具有改善的稳定性。使用这种试剂,酰化过程在鲁棒性方面得到改善,同时提高了产量和整体生产经济效益。这种新型酰化试剂对酰化药用肽和蛋白质如GLP-1、胰岛素、pYY和淀粉样蛋白具有用途。该发明还涉及一些新型GLP-1前体肽和衍生物,其中两个N-末端氨基已被删除。
