L‐quebrachitol Modulates the Anti‐convulsant Effects of Carbamazepine Possibly Through Voltage‐gated Sodium Channel Blocking Mechanism in Chicks: In Vivo and In Silico Studies

Brain and Behavior, Volume 15, Issue 7, July 2025.
L‐quebrachitol exhibited significant anticonvulsant effects in PTZ‐induced seizures in chicks, likely through voltage‐gated sodium channel inhibition. In vivo and in silico analyses suggest LQB may synergize with carbamazepine, offering a potential new therapeutic approach for epilepsy management. ABSTRACT Introduction L‐Quebrachitol (LQB), a naturally
