5-Fluorowillardiine is a selective agonist for the AMPA receptor,[1][2][3] with only limited effects at the kainate receptor.[4] It is an excitotoxic neurotoxin when used in vivo and so is rarely used in intact animals, but it is widely used to selectively stimulate AMPA receptors in vitro.[5][6][7]

5-Fluorowillardiine exists as two distinct isomers:

  • (2R) or D
  • (2S) or L
