rat α2-adrenergic receptor 5.7 nM (EC50) |
Tasipimidine (300-1000 μg/kg; subcutaneous injection; single dose) sulfate reduces the amplitude of the acoustic startle reflex in rats, with onset within 20 minutes, peak effect at 1 hour, and duration of at least 2 hours[1].
Tasipimidine (10-30 μg/kg; oral administration; total 3 treatment cycles) sulfate has an improving effect on separation anxiety in dogs[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Non-habituated mice[1]
-
Dosage:Subcutaneous injection: 10, 30 and 100 μg/kg
Oral administration: 900 and 3000 μg/kg -
Administration:Single dose
-
Result:Significantly reduced the activity count at doses of 30 μg/kg and higher doses, with 100 μg/kg showing a more pronounced effect by subcutaneous injection.
Significantly decreased the spontaneous locomotor activity of 3.0 mg/kg, while 0.9 mg/kg had no effect by oral administration.
-
Animal Model:Clinically healthy privately-owned dogs with a history of separation anxiety[2]
-
Dosage:10 and 30 μg/kg
-
Administration:Oral administration; three 4-day treatment periods in randomized order each followed by a 3-day washout
-
Result:Had a statistically significant treatment effect.
Led to more positive owner ratings, significantly reduced destructive/rearranging behavior and vocalization at dose of 30 μg/kg. Most dogs remained fully responsive and able to walk normally, with no serious adverse events reported.

Solvent & Solubility
DMSO : 125 mg/mL (378.38 mM; ultrasonic and warming and heat to 60°C; 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.

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 (6.30 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 (6.30 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.
