Biological Activity
| Targets | Amylin, Calcitonin receptor |
| ln Vivo | Fasting and non-fasted hyperglycemia are dose-dependently attenuated by oral calcitonin salmon treatment during the intervention period. Oral Calcitonin salmon treatment by dose reduces HbA1c levels by 1.7% and diabetic hyperglycemia by approximately 9 mM at the end of the study period. Moreover, oral Calcitonin salmon treatment results in a dose-dependently significant decrease in glucose excursions during the oral glucose tolerance test. Furthermore, oral Calcitonin Salmon treatment attenuates hyperglucagonaemia and hypersecretion of total glucagon-like peptide-1, primarily in the basal state, while maintaining hyperinsulinemia. Finally, at the conclusion of the study, pancreatic beta-cell function and beta-cell area are improved dose-dependently by oral Calcitonin salmon treatment[1]. |
| Animal Protocol | Rats: Oral Calcitonin salmon (sCT: 0.5, 1.0, or 2 mg/kg) or oral vehicle is administered twice daily to male ZDF rats from 8 to 18 weeks of age. The control group consists of Zucker lean rats. The levels of pancreatic and incretin hormones, glycosylated hemoglobin (HbA1c), and blood glucose measured both fasting and non-fasting. Beta-cell area and function were assessed, and the oral and intraperitoneal glucose tolerance tests were compared[1]. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (0.73 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (0.73 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: ≥ 2.5 mg/mL (0.73 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. Solubility in Formulation 4: 50 mg/mL (14.57 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication.  (Please use freshly prepared in vivo formulations for optimal results.) |
