Used as an active pharmaceutical ingredient in the development of drugs targeting neurological disorders, particularly as a selective inhibitor in modulating ion channel activity. It demonstrates potent activity in regulating neuronal excitability, making it valuable in research for treating epilepsy and chronic pain. Its structure allows for high binding affinity and selectivity, improving therapeutic efficacy while minimizing off-target effects. Employed in preclinical studies to evaluate central nervous system penetration and metabolic stability. Also utilized in structure-activity relationship (SAR) studies to design next-generation neurotherapeutics with improved pharmacokinetic profiles.
