Description

IC₅₀ & Target

nAChR^[1]

In Vitro

Hexamethonium Bromide (100 μM; 60 minutes) abolishes epibatidine-induced depolarisations of smooth muscle cells^[1].
The α3β4α5 receptors have greater sensitivity to Hexamethonium Bromide than the other potential ganglionic models, α3β4, α3β2, and α3β2α5^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Hexamethonium Bromide (0.2-25 mg/kg; i.v.) significantly reduces the renal sympathetic nerve activity (RSNA), mean arterial pressure (MAP) and heart rate (HR) in the Wistar rats and the spontaneously hypertensive rats (SHRs)^[4].
Hexamethonium Bromide (0.2-1.0 mg/kg; i.v.) treatments show no significant differences in the RSNA, MAP or HR between Wistar rats and SHRs^[4].
Hexamethonium Bromide (5.0-25 mg/kg; i.v.) results in a greater reduction in the RSNA and MAP in SHRs compared with Wistar rats^[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Male normotensive Wistar rats (280-320 g), SHRs^[4]
Dosage:	0.2 mg/kg, 1.0 mg/kg, 5.0 mg/kg, 25 mg/kg
Administration:	Intravenous injection
Result:	Significantly reduced the RSNA, MAP and HR in the Wistar rats and the SHRs.

* 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.

In Vivo:

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.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1.67 mg/mL (4.61 mM); Clear solution

This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1.67 mg/mL (4.61 mM); Clear solution

This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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.

Protocol 1

Add each solvent one by one: PBS
Solubility: 100 mg/mL (276.10 mM); Clear solution; Need ultrasonic
