Introduction of 205645-02-9 :

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[1].
