LY-404,039 is a drug used in scientific research that acts as a selective agonist for the metabotropic glutamate receptor group II subtypes mGluR2 and mGluR3.[1] A study shows considerable affinity (Ki = 8.2±1nM) for the D2High receptor as well, proposing a possible mechanism of action.[2] It has anxiolytic and antipsychotic effects in animal studies, but without causing sedation.[3]

Early human trials using a prodrug form of LY-404,039 called pomaglumetad methionil (LY-214,0023 monohydrate) have also given encouraging results.[4][5][6] A trial in 2009 failed to prove superiority over placebo or Olanzapine, but Lilly explained this as being due to an exceptionally high placebo response.[7] Eli Lilly terminated further development of the compound in 2012 after it failed in phase III clinical trials.[8][9] In September 2013 the results of a randomised placebo-controlled clinical trial investigating the impact of adjunctive pomaglumetad methionil on prominent negative symptoms in schizophrenia was published and failed to demonstrate any benefit from adjunctive pomaglumetad methionil.[10]
