NFPS exerts neuroprotection via glyR alpha1 subunit in the rat model of transient focal cerebral ischaemia and reperfusion. NFPS is a selective and non-competitive glycine transporter-1 (GlyT1) inhibitor (IC50s: 2.8 nM and 9.8 nM for hGlyT1 and rGlyT1, respectively).
BN 50739 is an antagonist of platelet-activating factor (PAF). BN 50739 suppresses certain cardiac arrhythmias. PAF is released from ischaemic myocardium and may contribute to initiation of ischaemia-induced ventricular fibrillation (VF)
LY 215490 is a selective, competitive and systemically active antagonist of AMPA receptor. LY 215490 has neuroprotective effect against focal ischaemia in a model of permanent MCA occlusion in the rat.
EGIS-8332 is a potent and selective non-competitive AMPA receptor antagonist. EGIS-8332 inhibits AMPA kainate ion channels and cell death. EGIS-8332 inhibited AMPA currents in rat cerebellar Purkinje cells and inhibited the AMPA- and quisqualate-induced excitotoxicity in primary cultures of telencephalon neurons (IC(50)=5.1-9.0 microM), in vitro. EGIS-8332 seems suitable for further development for the treatment of epilepsy, ischaemia and stroke based on its efficacy in a variety of experimental disease models, and on its low side effect potential.
