Alias Ro 15-1788

Flumazenil (Ro 15-1788) antagonizes the benzodiazepine binding site of the gamma-aminobutyric acid (GABA)/benzodiazepine receptor complex in the central nervous system (CNS), thereby preventing the chloride channel opening events and inhibiting neuronal hyperpolarization. As a result, flumazenil reverses benzodiazepine-induced effects including sedation, psychomotor deficits, amnesia, and hypoventilation in a dose-dependent manner. Flumazenil is an imidazobenzodiazepine derivative, effective in reversing benzodiazepine-induced activities.

Product Introduction

Bioactivity

Description	Flumazenil (Ro 15-1788) antagonizes the benzodiazepine binding site of the gamma-aminobutyric acid (GABA)/benzodiazepine receptor complex in the central nervous system (CNS), thereby preventing the chloride channel opening events and inhibiting neuronal hyperpolarization. As a result, flumazenil reverses benzodiazepine-induced effects including sedation, psychomotor deficits, amnesia, and hypoventilation in a dose-dependent manner. Flumazenil is an imidazobenzodiazepine derivative, effective in reversing benzodiazepine-induced activities.
In vitro	Flumazenil (1 mg/kg) demonstrated significant anxiolytic effects in BALB/c mice during elevated plus-maze and light/dark box tests. At a dose of 3 mg/kg, Flumazenil prevented changes induced by chronic ethanol withdrawal in mice, observed as decreased open arm time and the percentage of open arm entries. In rats, Flumazenil (10 mg/kg) effectively counteracted the sedative action produced by tetrahydroprogesterone. Additionally, Flumazenil antagonized the effects of diazepam in mice at doses ranging from 5-20 mg/kg, yet showed no effect on the anticonvulsant and adverse reactions associated with GYKI52466. While minimally decreasing the anticonvulsant activity of NBQX in the MES model and not in the PTZ test, Flumazenil binds to central benzodiazepine (BZD) receptors, thus antagonizing or reversing the neuropsychological and electrophysiological effects of BZD inverse agonists and agonists. Flumazenil can reverse sedative toxic reactions caused by the combined use of BZDs and other drugs, but it is ineffective in the case of cyclic antidepressant overdose.

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.
