NMDA receptor
Ibotenic acid (Ibo) is capable of acting at both NMDA and trans-ACPD receptors in the CNS, although only activation of NMDA receptors is involved in Ibo neurotoxicity. Ibotenic acid is toxic to cortical neurons exposes for 5 min with an EC 50 =77.3±8 μM (n=5) as measured by release of lactate dehydrogenase to the culture media.
