Propantheline bromide
Based on 1 Customer Validation
Propantheline bromide is an orally active mAChR antagonist. Propantheline bromide can be used in the research of smooth muscle dysfunction, excessive sweating, cramps or spasms of the stomach, intestines or bladder, and involuntary urination. Propantheline bromide can hardly cross the blood-brain barrier.

Biological Activity
mAChR[1]
Propantheline bromide (10 μM-1 mM) decreases urinary bladder smooth muscle reactivity to Acetylcholine[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Propantheline bromide, when administered alone, has no central activity (does not affect memory impairment in mice with cerebral ischemia) and has no effect on AChE activity in the brain[4].
Therefore, propantheline bromide can be used in combination with cholinesterase inhibitors to suppress the peripheral side effects (such as gastrointestinal reactions) of this series of inhibitors without affecting their central regulatory activity (such as improving cognitive and memory impairment)[4].

Storage
4°C, sealed storage, away from moisture
* In solvent : -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture)
Solvent & Solubility
DMSO : ≥ 100 mg/mL (223.02 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 50 mg/mL (111.51 mM; Need ultrasonic)
* "≥" means soluble, but saturation unknown.
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.

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
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 (5.58 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 (5.58 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.
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.
Add each solvent one by one: PBS
Solubility: 130 mg/mL (289.93 mM); Clear solution; Need ultrasonic
