In the SRED model of hippocampus cells, carisbamate (200 µM; 12 hours) exhibits anti-epileptic properties [1]. Long-lasting effects on hippocampal neurons are demonstrated by carisbamate (200 µM; 24 hours), which are not correlated with antiepileptic effects in vitro [1]. In the few neurons that still occasionally experience epileptiform events, carisbamate not only inhibits the development and expression of SRED in the majority of neurons, but it also shortens the duration and frequency of seizures [1]. Hippocampal cells with injury resembling status epilepticus can benefit from neuroprotective actions of carisbamate (200 µM) [1].

| ln Vivo |
Carisbamate (10, 30, 60 mg/kg; intraperitoneal injection; single dosage) dose-dependently lowers the expression of spike-wave discharges (SWD) in a rat model of absence seizures [2]. Carisbamate (20, 30 mg/kg; i.p.; single dosage) did not elicit galloping or tonic seizures in any of the rats examined [2].

| Cell Assay |
Cell Viability Assay[1]
Cell Types: Hippocampal cells (from postnatal day 2 Sprague-Dawley rats; Spontaneous Recurrent Epileptiform Discharges (SRED) model) Tested Concentrations: 200 µM Incubation Duration: 12 hrs (hours) Experimental Results: Response to SRED The acute inhibition rate is greater than 95% of neurons showing anti-epileptic effects in vitro. Cell viability assay[1] Cell Types: Hippocampal cells (SREDs model) Tested Concentrations: 200 µM Incubation Duration: 24 hrs (hours) Experimental Results: Display cells evaluated the day after treatment still had no in vitro epileptic activity and no SREDs were formed. |
| Animal Protocol |
Animal/Disease Models: Male genetic absence epilepsy rat (absence seizure model) [2].
Doses: 10, 30, 60 mg/kg Route of Administration: intraperitoneal (ip) injection; single. Experimental Results: SWD was completely inhibited after 120 min at 60 mg/kg, and SWD duration returned to control levels after 100 min at 30 mg/kg. Animal/Disease Models: Male Wistar hearing-sensitive rat (convulsive seizure model) [2]. Doses: 10, 20, 30 mg/kg Route of Administration: intraperitoneal (ip) injection; single. Experimental Results: At doses of 20 and 30 mg/kg, none of the rats tested developed galloping or tonic seizures. At a dose of 10 mg/kg, 6 of the 8 rats studied still developed tonic seizure latency, which increased by 327%. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (11.59 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (11.59 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
