Activité biologique
The cell viability in the presence of alarelin was significantly lower than that in the absence of alarelin. The maximum stimulatory effect on cell viability was achieved at a concentration of 10-5 M and it acted in a dose-dependent manner[1]

In vivo drug discovery for increasing incretin-expressing cells identifies DYRK inhibitors that reinforce the enteroendocrine system. [Abstract]2022 Sep 15;29(9):1368-1380.e5. PMID: 35998625
Solvant et solubilité
H2O : 100 mg/mL (77.67 mM; Need ultrasonic)
DMSO : 62.5 mg/mL (48.55 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (1.62 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (1.62 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocole
The cells are trypsinized in a solution of 2.5 g/L trypsin and seeded in a 96-well plate. After the cells are grown for 24 h to approximately 800 g/L subconfluent state, 0.1 mL medium containing 2.5% calf serum and various concentrations (0.001, 0.1, 10 μM) of alarelin is added to each well, respectively, and incubated for 24 h in a CO2 incubator. Each concentration is tested in at least 12 wells. Briefly, 15 μL of MTT solution is added to each well and incubated for 4 h. Then, the medium and MTT are removed and 150 μL of DMSO is added to each well and shaken for 10 min to dissolve the crystal. The OD is determined at 490 nm using an ELISA reader[1].

Rats: Male Sprague-Dawley rats are divided into two groups. In Group I: Gastric acid secretion is measured in a chambered stomach. Briefly, the abdomen is incised, and both the stomach and duodemun are exposed and tied respectively; then 1.5 mL 0.9% sodium chloride (containing Alarelin, 2 μg/kg) is infused into the each chambered stomach. After 15, 30, 45, 60 min, the gastric juice is drew out of the chambered stomach and the pH is measured in the ABL-500 respectively. The control is infused saline instead of Alarelin. In Group II: After anaesthetized, 2 mL Alarelin (2 μg/kg) is administered into the tail vein. The control is injected the saline instead of Alarelin. Then, the stomach and duodenum are tied and infused 1.5 mL saline immediately. After 15, 30, 45, 60 min, the gastric juice is also drew out of the chambered stomach and the pH is measured in the ABL-500 respectively[2].
