Novel synthetic polypeptide derivatives, i.e., novel calcitonin derivatives, having improved basic physiological activities of the corresponding natural calcitonins, i.e., the activity for lowering the blood level of calcium, the activity as an analgesic, as well as the activity for inhibiting the secretion of the gastric juice. Thus these synthetic calcitonins are effective as agents for curing hypercalcemia, analgetic agents, anti-ulcerative agents and the like.
