β adrenergic receptor |
Amibegron hydrochloride (SR 58611A) is a selective β-adrenoceptor agonist, with an EC50 of 3.5 nM for β-adrenoceptor in rat colon, and 499 nM in rat uterus[1]. Amibegron hydrochloride (SR 58611A) shows little effect on β1- and β2-adrenoceptors, 5-HT uptake, noradrenaline (NA) uptake, and dopamine (DA) uptake from rat brain tissue, with IC50s of 4.6 and 1.2, 0.58, 2.5 and 3.2 μM, respectively; exhibits no effect on 5-HT1A, 5-HT2, MAO-A and MAO-B (IC50 > 10 μM)[2].

* In solvent : -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture)
Solvent & Solubility
DMSO : 100 mg/mL (227.09 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.

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: ≥ 2.5 mg/mL (5.68 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (5.68 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Mice[2]
This test is performed on groups of 10-20 mice. Amibegron hydrochloride (0.1 to 0.3 mg/kg) or vehicle are administered i.p. 30 min before the administration of yohimbine. Yohimbine hydrochloride is administered s.c. at a dose of 30 mg/kg always at the same time of day, between 1.30 and 3.30 p.m. Lethality is recorded the next morning at 9 a.m[2].
Rats[2]
The rats (n = 10 per group) are treated randomly according to one of the following protocols: the control sample, which receives no shock, is given vehicle; experimental animals with inescapable shock are treated daily with vehicle or Amibegron hydrochloride (up to 30 mg/kg). Animals are treated orally over 5 consecutive days, i.e. 6 h after shock pretreatment on day 1, and then twice per day, a half dose in the morning (30 min before shuttle-box session) and a half dose in the afternoon (except on the 5th day). Statistical analysis is performed on themean number of escape failures using a two-way analysis of variance followed by Dunnett's test[2].
