Inhibitor of neuronal voltage-gated Na+ channels. Exhibits anticonvulsant activity. Potentiates GABA-induced Cl- currents in HEK 293 cells expressing the GABAA receptor α1β2γ2 subtype combination. Can induce autophagy by inhibiting inositol synthesis. Also delays disease onset and prolongs survival in a mouse amyotrophic lateral sclerosis (ALS) model, as well as reducing motor neuron loss and altered muscle morphology. Purity 99%.
