iGluR

Ionotropic glutamate receptors

iGluR (ionotropic glutamate receptor) is a ligand-gated ion channel that is activated by the neurotransmitter glutamate. iGluR are integral membrane proteins compose of four large subunits that form a central ion channel pore. Sequence similarity among all known glutamate receptor subunits, including the AMPA, kainate, NMDA, and δ receptors.

AMPA receptors are the main charge carriers during basal transmission, permitting influx of sodium ions to depolarise the postsynaptic membrane. NMDA receptors are blocked by magnesium ions and therefore only permit ion flux following prior depolarisation. This enables them to act as coincidence detectors for synaptic plasticity. Calcium influx through NMDA receptors leads to persistent modifications in the strength of synaptic transmission.

    SPD-502 sodium
    SPD-502 sodium is a novel glutamate antagonist with potential neuroprotective properties, particularly in brain ischemia. It selectively targets the AMPA receptor, showing high affinity (IC50 = 0.043 μM) and competitive inhibition of AMPA-induced effects in rat cortical membranes and cultured mouse cortical neurons. In vivo, SPD-502 sodium effectively blocks AMPA-evoked spike activity in the hippocampus after intravenous administration, significantly increasing the seizure threshold in mice and demonstrating robust protection against ischemia-induced damage to hippocampal neurons in gerbils. These findings suggest SPD-502 sodium may be promising for treating neurodegenerative conditions associated with glutamate excitotoxicity.
