“New Study Explores Antiseizure Potential of Plant Compounds Similar to Cannabinoids”
In a recent study, researchers investigated the antiseizure effects of three compounds—amorfrutin 2, honokiol, and magnolol—that have a similar structure to cannabinoids but come from non-cannabis plants. These compounds were tested to see if they could help with drug-resistant forms of epilepsy, specifically in mouse models that mimic conditions like Dravet syndrome and Lennox–Gastaut syndrome. Given that cannabinoids like cannabidiol have shown promise in treating seizures, the team wanted to explore whether these plant-based compounds could offer similar benefits.
To do this, the researchers assessed how these compounds acted in the brain and bloodstream, and they set up several experiments to evaluate their effectiveness in preventing seizures. They used a hyperthermia-induced seizure model in mice to see how well these compounds could increase the seizure threshold—essentially, raising the body temperature needed to trigger a seizure. They also conducted tests using the maximal electroshock method and another mouse model to further evaluate their efficacy.
The results were quite promising! Magnolol and honokiol showed high concentrations in the brain compared to the plasma, indicating they were effectively reaching the site of action. Both amorfrutin 2 and magnolol were able to raise the temperature threshold for seizures in the Dravet syndrome model, with magnolol further showing a reduction in the frequency and duration of atypical absence seizures in the Lennox–Gastaut model. Although the compounds inhibited certain calcium channels linked to seizure activity, they didn’t seem to affect the cannabinoid receptors directly.
This study is significant because it highlights the potential of amorfrutin 2 and magnolol as new candidates for developing antiseizure medications. Given that many epilepsy treatments can be ineffective for some patients, exploring these non-cannabis compounds could lead to valuable new therapies for individuals with intractable epilepsy. The findings suggest a hopeful avenue for future drug discovery focused on these plant-derived compounds, paving the way for breakthroughs in treatment.
