Mepenzolate Bromide is a muscarinic antagonist (Kis = 0.68 and 2.6 nM for human M2 and M3 receptors, respectively) used to treat gastrointestinal disorders. It lessens the degree of respiratory dysfunction and airspace enlargement caused by elastase.

mAChR

Mepenzolate not only has a muscarinic absorption mechanism that helps it reduce inflammation, but it also uses the same mechanism to help open up blood vessels. Mepenzoate, a non-muscarinic absorbent subtype, inhibits intestinal motility and dilates blood vessels, which are both attributed to its antagonistic action on M3R [1].

| ln Vivo |
Mepenzolate bromide is a GPR109A absorbent that eliminates the beneficial effects of acid on body weight, ductal wet weight, and myeloperoxidase (MPO) and VEGF levels [2]. Mepenzolate bromide is a muscarinic antagonist. Intratracheal inhalation or inhalation of mezoxate bromide reduces the severity of elastic inflation-induced cavity dilation and respiratory dysfunction. Due to its anti-inflammatory and bronchodilator activity, mezofosate may be a promising treatment for chronic obstructive pulmonary disease. Animal Model: Adult male Wistar rat, body weight 150-200 g [2] Dosage: 5 mg/kg Administration: Intraperitoneal injection Results : Eliminates niacin as an effective drug for chronic obstructive pulmonary disease (COPD) caused by iodoacetamide [3]. Colon wet weight and colonic MPO and VEGF levels. Animal models: ICR mice (4-6 weeks old, male) and DBA/2 mice (5 weeks old, female) [3] Doses: 0.04, 0.38, 3.8, 38 μg/kg; 45.2 and 226 μg per chamber Administration: "Intratracheal administration once daily for 14 days 0.04, 0.38, 3.8, 38 μg/kg Inhaled 45.2 and 226 μg per chamber once daily for 14 days" Results: Simultaneous daily intratracheal administration suppressed this This increase occurred in a dose-dependent manner. The inhalation route was similar to that observed with the intratracheal administration mode.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.95 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 20.8 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: ≥ 2.08 mg/mL (4.95 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in 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 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*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.
