In order to establish a new process for large-scale production of highly purified secretin, a synthesis based on a new strategy was investigated. A maximal protection method applying the HF deprotecting procedure in the final stage was employed. Six small protected fragments (2-6, 7-10, 11-13, 14-17, 18-22, 23-27) were each prepared by stepwise chain elongation. Thereafter, three protected fragments (1-10, 11-17, 18-27) were synthesized from them, and assembled to prepare the protected secretin. The optical purity of the product after each fragment condensation was checked by high performance liquid chromatography. Completely protected secretin having a high degree of chemical and optical homogeneity was obtained.
为了建立大规模生产高纯度胰泌素的新工艺,研究人员研究了一种基于新策略的合成方法。在最后阶段采用了高频脱保护程序的最大保护方法。通过分步链延长法分别制备了六个小的受保护片段(2-6、7-10、11-13、14-17、18-22、23-27)。然后,由它们合成三个受保护的片段(1-10、11-17、18-27),并组装成受保护的泌乳素。高效液相色谱法检测了每个片段缩合后产物的光学纯度。得到的完全保护泌乳素具有高度的化学和光学均一性。
