LY404039 is a potent, selective and orally activemGluR2andmGluR3agonist withK_is of 149 nM and 92 nM forrecombinant humanmGluR2andmGluR3, respectively. LY404039 shows >100-fold selectivity for mGluR2/3 over other receptors/transproters. LY404039 has antipsychotic and anxiolytic effects^[1].

LY404039 is a nanomolar potent agonist in rat neurons expressing native mGlu2/3 receptors (K_i= 88 nM)^[1].
Functionally, LY404039 potently inhibits Forskolin-stimulated cAMP formation in cells expressing human mGlu2 (EC₅₀= 23 nM) and mGlu3 receptors (EC₅₀= 48 nM)^[1].
Electrophysiological studies indicate that LY404039 suppresses electrically evoked excitatory activity in the striatum, and serotonin-induced L-glutamate release in the prefrontal cortex. LY404039 suppresses the frequency of 5-HT-induced excitatory postsynaptic currents (EPSCs) with an EC₅₀of 82.3 nM and with a near maximal suppression of 85.6% at 1 μM^[1].
LY404039 inhibits the binding of the D2-specific antagonist, [3H]domperidone, to the human cloned D2 receptor with dissociation constants of 8.2 nM at D2High and 1640 nM at D2Low. Using rat striatal tissue, LY404039 has dissociation constants of 12.6 nM at D2High and 2100 nM at D2Low^[2].

LY404039 attenuates amphetamine- and phencyclidine-induced hyperlocomotion (3-30 and 10 mg/kg, respectively). LY404039 (3-10 mg/kg) inhibits conditioned avoidance responding. LY404039 also reduces fear-potentiated startle in rats (3-30 μg/kg) and marble burying in mice (3-10 mg/kg), indicating anxiolytic-like effects. LY404039 (10 mg/kg) also increases dopamine and serotonin release/turnover in the prefrontal cortex^[3].
Following oral administration of LY404039 to fasted rats at doses of 1, 3, or 10 mg/kg, exposure increased proportionally with dose. LY404039 (10 mg/kg; p.o.) treatment shows the C_maxis 1528.5 ng/mL and T_maxis 2 hours in rats^[1].
