Abstract Background Numerous data indicates that hallucinogens from various groups such as ketamine, scopolamine or psilocybin exert rapid antidepressant effects in both preclinical and clinical studies. Group II glutamate (mGlu) metabotropic receptor antagonists also show rapid antidepressant efficacy in animal studies, moreover we have shown that mGluR2/3 antagonist, LY341495 is able to...
Partial negative allosteric modulators (NAM) of the metabotropic glutamate 5 (mGlu5) receptor are an excellent alternative to full antagonists and NAMs because they retain therapeutic effects and have a much broader therapeutic window. Here, we investigated whether partial mGlu5 NAM, 2-(2-(3-methoxyphenyl)ethynyl)-5-methylpyridine (M-5MPEP), induced a fast and sustained antidepressant-like...
