5-Iodowillardiine is a selective agonist for the kainate receptor, with only limited effects at the AMPA receptor.^[1] It is selective for kainate receptors composed of GluR5 subunits.^[2][3] It is an excitotoxic neurotoxin in vivo,^[4][5] but has proved highly useful for characterising the subtypes and function of the various kainate receptors in the brain and spinal cord.^[6][7][8]
