metabotropic glutamate receptor The metabotropic glutamate receptors, or mGluRs, are a type of glutamate receptor that are active through an indirect metabotropic process. They are members of the group C family of G-protein-coupled receptors, or GPCRs. Like all glutamate re ...

subtype mGluR₅, binding with nanomolar affinity and over 1000 times selectivity over all other receptor targets tested. In animal studies it was found to have a high oral bioavailability and a long duration of action, lasting 18 hours after a single dose, giving it considerably improved properties over older mGluR₅ antagonists such as MPEP and

fenobam Fenobam is an imidazole derivative developed by McNeil Laboratories in the late 1970s as a novel anxiolytic drug with an at-the-time-unidentified molecular target in the brain. Subsequently, it was determined that fenobam acts as a potent and s ...
