Product Introduction

Bioactivity

Description	Hexamethonium Bromide (Hexamethonium Dibromide), a specific antagonist of neuronal-type nicotinic AChR in ganglia, is poorly absorbed from the gastrointestinal tract and does not cross the blood-brain barrier.
In vitro	Hexamethonium Bromide is effective against Ach and carbachol (CCh) on the amplitude of endplate responses of rat omohyoid muscle with EC50 of 300 μM and 100 μM, respectively. Hexamethonium Bromide (50-200 μM) causes an increase in the amplitude of nerve-evoked endplate currents (e.p.cs) recorded in the presence of 0.6 μM tubocurarine. Hexamethonium Bromide is also a weak inhibitor of acetylcholinesterase activity in rat muscle homogenates with EC50 of 1.5 mM. [1] Hexamethonium Bromide (200 μM) decreases the time constant of decay of both endplate currents (e.p.cs) (by ~25%) and miniature endplate currents (m.e.p.cs) (by ~20%) in the rat hemi-diaphragm muscle. At low frequencies of stimulation (0.5-2 Hz), Hexamethonium Bromide (200 μM) increases e.p.c. quantal content by 30-40%. [2]

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
