Abecarnil
Based on 1 Customer Validation
Abecarnil (ZK 112119) is a ligand or a partial agonist for benzodiazepine (BZ) receptor. Abecarnil possesses anxiolytic and anticonvulsant properties. Abecarnil can act as a positive allosteric modulator of GABAA receptor. Abecarnil inhibits the binding of the BZ [3H]lormetazepam to rat cerebral cortex membranes, with an IC50 of 0.82 nM. Abecarnil can be used for epilepsy research.

Biological Activity
Abecarnil enhances the binding of t-[35S]butylbicyclophosphorothionate to rat cortical membranes[1].
Abecarnil exhibits a 3- to 6-fold higher affinity to forebrain BZ receptors than Diazepam (DZP)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Abecarnil (0-2.5 mg/kg, IP, once) dose dependently reduces epileptic activity[3].
Abecarnil is effective against sound-induced convulsions in DBA/2 mice, against air blast-induced generalized seizures in gerbils and against myoclonus in baboons Papio papio[4].
Abecarnil is 2-10 times more potent than DZP in most rodent tests of anxiolytic activity, and in reducing locomotor activity in mice and rats thoroughly habituated to the test chamber[1].

-
Animal Model:Male Sprague-Dawley CD rats (200-250 g)[2]
-
Dosage:0.3 mg/kg
-
Administration:IP, once, given 30 min before sacrifice
-
Result:Failed to change the basal pregnenolone and progesterone, while only slightly decreased THDOC levels, but antagonized the brain neuroactive steroid increase induced by foot shock.
-
Animal Model:WAG/Rij rats (male and female, 190-380 g, age 13-19 weeks, 8 rats each group)[3]
-
Dosage:0, 0.16, 0.4, 1.0, and 2.5 mg/kg; 1 mL/400 g
-
Administration:IP, once
-
Result:Reduced the duration of spike-wave discharges and increased immobile behavior. Dose dependently reduced epileptic activity, whether measured as number, mean duration, or total duration of spike-wave discharges. The ED50 for reducing the number of spike-wave discharges in the second hour was 0.4 mg/kg.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (6.18 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.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
