DCG-IV is a research drug which acts as a group-selective agonist for the group II metabotropic glutamate receptors (mGluR2/3).[1] It has potent neuroprotective and anticonvulsant effects in animal studies,[2][3][4][5] as well as showing anti-Parkinsonian effects,[6][7] but also impairs the formation of memories.[8][9]
