Metabotropic glutamate receptors (mGluR1-8) are G protein-coupled receptors that function to modulate brain excitatory signaling via presynaptic, postsynaptic, and glial mechanisms.{21634} DL-AP3 is a competitive mGluR1 antagonist that demonstrates a Ki value of 298 ?M and an IC50 value of 1mM for rat mGluR1? when challenged with glutamate.{21635} DL-AP3 can antagonize excitatory amino acid-induced phosphoinositide hydrolysis, induce Ca2+ mobilization in rat hippocampal slices, and inhibit phosphoserine phosphatase in rat brain cortex.{21634,21632} At concentrations from 10-300 ?M DL-AP3 has been used to characterize the role of mGluR in long-term potentiation in the hippocampus in a model of learning and memory, the release of glutamate in Parkinson’s disease, and the increased activity of mGluR implicated in fragile X syndrome.{21633,21631,21630}
