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.
