Description

Etifoxine hydrochloride, a non-benzodiazepine GABAergic compound, is a positive allosteric modulator of α1β2γ2 and α1β3γ2 subunit-containing GABAA receptors. Etifoxine hydrochloride reveals anxiolytic and anticonvulsant properties in rodents[1][2][3].

In Vitro

Etifoxine (EFX), at concentrations ranging from 10 to 300 μM (higher concentrations limited its solubility), produces a dose-dependent increase in the [3H]muscimol binding at equilibrium, to 155±2% of its control value at 300 μM EFX[1].

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

In Vivo

Etifoxine competitively inhibits [35S]TBPS binding with micromolar potency in rat brain[1].
Etifoxine (3.125-50 mg/kg) exhibits more pronounced anxiolytic and anticonvulsant effects in the BALB/cByJ mice compared to the C57BL/6J mice[3].

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

Animal Model: Six-week old BALB/cByJ and C57BL/6J mice (20-25 g)[3].
Dosage: 3.125-50 mg/kg.
Administration: Intraperitoneal inhection.
Result: Significantly increased the amount of time spent on the open arms at the 12.5 mg/kg dose when compared to vehicle (p = 0.009) in BALB/cByJ mice but produced no effect in C57B/6J mice.
BALB/cByJ mice compared with C57BL/6J mice exhibited significantly (p < 0.012) lower plasma levels of the compound at 15 and 30 min.

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: ≥ 2.5 mg/mL (7.41 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (7.41 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
