Benztropine mesylate (NSC-42199; ST-50997629; NSC 42199; ST 50997629; Cogentin; MLS000737056), the mesilate salt of Benztropine, is a highly potent dopamine transporter (DAT) inhibitor used for the treatment of symptoms of Parkinson's disease such as involuntary tremor and dystonia. It suppresses the dopamine transporter with an IC50 of 118 nM. Benztropine is a synthetic substance that acts centrally to sabotage M1 muscarinic acetylcholine receptors. It is derived from the combination of atropine and diphenhydramine.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.20 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 (6.20 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. View More
Solubility in Formulation 3: 100 mg/mL (247.81 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication. |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 2.4781 mL | 12.3907 mL | 24.7813 mL | |
| 5 mM | 0.4956 mL | 2.4781 mL | 4.9563 mL | |
| 10 mM | 0.2478 mL | 1.2391 mL | 2.4781 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
