The [2-serine, 8-valine]-analog of human calcitonin (1) was synthesized by the liquid phase method. Analog 1 was built up from five fragments with minimized protection for the side functional groups. These fragments were linked step wise to the C-terminal fragments by the azide method. A gel filtration was effectively applied for the purification of the resulting pep tide in each fragment condensation. Analog 1 had about the same hypocalcemic activity as that of human calcitonin. The result showed that the high activity of eel or salmon calcitonin 1 or 2 is not ascribable only to the amino acid sequence of their N-terminal decapeptide.
[2-丝氨酸, 8-缬氨酸]型人降钙素(1)通过液相法合成。模拟物1由五个片段构建而成,这些片段侧功能团保护最少。这些片段通过叠氮法逐步与C末端片段连接。每一步片段缩合后,凝胶过滤法有效地应用于所得肽的纯化。模拟物1具有与人降钙素相似的降血钙活性。结果表明,鳗鱼或鲑鱼降钙素1或2的高活性并不仅仅归因于其N端十肽的氨基酸序列。
