Mechanism of Action

Targets/IC₅₀/Ki	NMDA receptor
In vitro	NMDA (N-Methyl-D-aspartic acid) is an excitatory amino acid neurotransmitter that specifically binds to the NR2 subunits of its receptor without affecting other glutamate receptors (such as those for AMPA and kainate). This compound stimulates the opening of a non-specific cation channel, allowing the passage of Ca²⁺ and Na²⁺ into the cell and K⁺ out of the cell. Its activation can produce excitatory postsynaptic potentials (EPSP) and trigger an increase in intracellular Ca²⁺ content, which may further participate in various signaling pathways. The NMDA receptor plays a key role in a wide range of physiological (e.g., long-term potentiation and neuronal plasticity) and pathological processes (e.g., excitotoxicity and epilepsy).
