Radiprodil, a NR2B negative allosteric modulator, from bench to bedside in infantile spasm syndrome.

Radiprodil showed prominent anti-seizure effect in juvenile animals, consistent with the prevalent expression of NR2B subunit of the NMDA receptor at this age in both rodents and humans. The clinical testing, although preliminary, showed that radiprodil is associated with a good safety and pharmacokinetic profile, and with the potential to control epileptic spasms.
