Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC50/Ki
Dopamine subtype 2 receptor [1]
AChR [1]
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]
