  Abstract: Amino diacid 3, a highly selective   competitive GluR5 kainate receptor antagonist, exhibited high   GluR5 receptor affinity and selectivity over other glutamate   receptors. Its diethyl ester prodrug 4 was orally active in two   models of migraine: the neurogenic dural plasma protein   extravasation model and the nucleus caudalis c-fos expression   model. These data suggest that a GluR5 kainate receptor   antagonist might be an efficacious antimigraine therapy with a   novel mechanism of action.
