Description
YM90K is a potent and selective AMPA receptor antagonist with a Ki of 84 nM. YM90K is less potent in inhibiting kainate (Ki of 2.2 μM) and NMDA (Ki of 37 μM) receptors. YM90K has neuroprotective actions.

How to use
In Vitro:
YM90K co-injected with AMPA or kainate into the rat striatum protect cholinergic neurons against AMPA- or kainate-induced neurotoxicity.
In Vivo:
YM90K shows potent suppressive activity against audiogenic seizure in DBA/2 mice; ED50 values of YM90K against tonic seizure is 2.54 mg/kg (i.p.). The duration of the anticonvulsant effects of YM90K is 30 min. In a global ischemia model, YM90K (15 mg/kg i.p.) significantly prevents the delayed neuronal death in the hippocampal CA1 region in Mongolian gerbils when administered 1 h after 5-min ischemia. The therapeutic time window for the neuroprotective effect of YM90K (30 mg/kg i.p.) is 6 h. In a focal ischemia model, YM90K (30 mg/kg i.v. bolus+10 mg/kg/h for 4 h) reduces the volume of ischemic damage in the cerebral cortex in F344 rats.
