A novel synthesis of human CLIP, a peptide corresponding to the sequence of human ACTH-(18-39) is described. The dodecapeptide chain was assembled by a combination of fragment condensation and stepwise synthesis while using N alpha-benzyloxycarbonyl and side chain tert.-butyl-derived protective groups combination. The final deprotection was performed by acidolysis in trifluoroacetic acid. The end product was purified by ion exchange chromatography on carboxymethyl cellulose.
描述了一种新型的人促肾上腺皮质激素样中间肽(CLIP)的合成方法,该肽对应于人促肾上腺皮质激素(ACTH)-(18-39)的序列。使用Nα-苄氧羰基和侧链叔丁基衍生的保护基团组合,通过片段缩合和逐步合成相结合的方式组装十二肽链。最终的脱保护通过在三氟乙酸中进行酸解来完成。终产物通过在羧甲基纤维素上进行离子交换色谱法进行纯化。
