1-Amino-1,3-dicarboxycyclopentane (ACPD) is a chemical compound that binds to the metabotropic glutamate receptor (mGluR),^[2] acting as a mGluR agonist. ACPD is a rigid analogue of the neurotransmitter glutamate and does not activate ionotropic glutamate receptors.^[3] However, it has been reported to be an agonist of the glycine site of the NMDA receptor.^{[citation needed]} ACPD can induce convulsions in neonatal rats.^[4]
