Riluzole (hydrochloride)

Riluzole (hydrochloride) (CAS No.: 850608-87-6) is a small-molecule anticonvulsant agent classified as a use-dependent voltage-gated sodium channel blocker, widely employed in neuropharmacology and ion channel research. It modulates neuronal excitability primarily through inhibition of sodium ion influx and attenuation of glutamatergic signaling, and has also been shown to suppress γ-aminobutyric acid (GABA) uptake with activity in the low micromolar range, thereby influencing synaptic neurotransmission dynamics. In addition to its role as a sodium channel modulator, riluzole hydrochloride exhibits properties consistent with sodium–glutamate pathway antagonism, making it a valuable tool for investigating mechanisms of excitotoxicity, neuronal injury, and signal transduction abnormalities. This compound is commonly utilized in cellular and animal models to study neurodegenerative processes, synaptic dysfunction, and related molecular pathways, as well as in exploratory oncology research examining its effects on cell proliferation and survival signaling. Experimental applications typically involve concentration ranges and dosing regimens tailored to specific model systems and study objectives, supporting its broad utility in mechanistic studies and compound screening within neuroscience and drug discovery contexts.
