Merck, 445874-5MG, mGluR5 Antagonist, MTEP

General description
A brain-permeable (thiazole-pyridine)alkyne compound that acts as a potent, selective and non-competitive mGluR5 (metabotropic glutamate receptor subtype-5) antagonist (IC₅₀ = 5 nM in Ca²⁺-flux assay; Ki = 16 nM) with in vivo anxiolytic activity in a rodent model (ED₅₀ = 1 mg/kg, ip and 7 mg/kg, po). Devoid of any side effects seen with MPEP and benzodiazepines. Reported to weakly affect the activities of other enzymes and receptors tested (IC₅₀ = 30 µM for MAO-A, >100 µM for mGlu1R, 2R & 7R, and >300 µM for NR2BR).
