基本描述
Carbocalcitonin, the amino-suberic acid analog of eel calcitonin, has all the biological properties of the corresponding natural calcitonin. The substitution of the disulfide bond of natural calcitonins with an ethylene bridge in the 1-7 N-terminal position gives elcatonin greater stability and excellent tolerability when used in vivo.

Amylin, Calcitonin receptor[1].
体内研究 (In Vivo)
Oral Calcitonin salmon treatment dose-dependently attenuates fasting and non-fasted hyperglycaemia during the intervention period. At the end of the study period, oral Calcitonin salmon treatment by dose decreases diabetic hyperglycaemia by ~9 mM and reduces HbA1c levels by 1.7%. Furthermore, a pronounced reduction in glucose excursions is dose-dependently observed for oral Calcitonin salmon treatment during oral glucose tolerance test. In addition, oral Calcitonin salmon treatment sustains hyperinsulinaemia and attenuates hyperglucagonaemia and hypersecretion of total glucagon-like peptide-1 predominantly in the basal state. Lastly, oral Calcitonin salmon treatment dose-dependently improves pancreatic beta-cell function and beta-cell area at study end[1].

Animal Administration [1]
Rats[1] Male ZDF rats are treated with oral Calcitonin salmon (sCT: 0.5, 1.0 or 2 mg/kg) or oral vehicle twice daily from age 8 to 18 weeks. Zucker lean rats serve as control group. Fasting and non-fasted blood glucose, glycosylated haemoglobin (HbA1c) and levels of pancreas and incretin hormones are determined. Oral glucose tolerance test and i.p. glucose tolerance test were compared, and beta-cell area and function were evaluated[1].
