Segment condensations were performed to construct peptide fragments related to Sulfolobus solifataricus Ribonuclease. At each condensation step, the new protecting groups were stable. The protected peptide fragments were treated with a low-high HF procedure to give the desired peptide fragments. These peptide fragments were also prepared by the solid-phase method, and the obtained peptides were compared
进行片段缩合以构建与Sulfolobus solifataricus核糖核酸酶有关的肽片段。在每个缩合步骤,新的保护基是稳定的。用低-高HF程序处理受保护的肽片段,得到所需的肽片段。还通过固相方法制备这些肽片段,并将获得的肽与通过溶液法获得的肽进行比较。通过溶液法获得的肽片段与在分析型HPLC上通过固相法获得的肽片段相同,这表明新的保护基很容易被HF去除,并且在被保护肽的合成过程中未发生外消旋作用。
