Mechanism of Action

Features	Under investigation as an exciting new medicine that may herald the arrival of third-generation antipsychotic drugs.
Targets/IC₅₀/Ki	Rat neurons expressing native mGlu2/3 ^[1] 88 nM(Ki) Recombinant human mGlu3 ^[1] 92 nM(Ki) Recombinant human mGlu2 ^[1] 149 nM(Ki)
In vitro	Pomaglumetad (LY404039) exhibits low binding affinity to group III mGlu receptors including mGlu6, mGlu7 and mGlu8 with a K_i value more than 5 μM, and shows little affinity for ionotropic glutamate receptors, glutamate transporter subtypes, monoamine and other receptors. It potently inhibits forskolin-stimulated cAMP formation in cells expressing human mGlu2 and mGlu3 receptors. This compound suppresses electrically evoked excitatory activity in the striatum, and serotonin-induced L-glutamate release in the prefrontal cortex. It could modulate glutamatergic activity in limbic and forebrain areas relevant to psychiatric disorders and may be devoid of negative side effects associated with current antipsychotics and anxiolytics. ^[1]
In vivo	Pomaglumetad (LY404039) demonstrates higher plasma exposure and better oral bioavailability, and may be valuable in the treatment of neuropsychiatric disorders, including anxiety and psychosis. ^[1] In wild-type animals, this compound significantly reverses d-amphetamine(AMP)-induced increase in ambulations, distance traveled, and reduced time spent at rest. It reverses phencyclidine (PCP)-evoked behaviors at 10 mg/kg. The antipsychotic-like effects of LY404039 on PCP and AMP-evoked behavioral activation are absent in mGlu2 and mGlu2/3 but not in mGlu3 receptor-deficient mice. In contrast, clozapine and risperidone inhibit PCP-evoked behaviors in both wild-type and mGlu2/3 receptor-deficient mice. ^[2] It reduces responding on the EtOH in the pavlovian spontaneous recovery (PSR) test and reduces the expression of an alcohol deprivation effect (ADE) during relapse, but does not affect EtOH responding under maintenance conditions. This compound inhibits the expression of alcohol seeking and relapse behavior without altering alcohol self-administration behavior. ^[3] Moreover, it attenuates amphetamine- and phencyclidine-induced hyperlocomotion. It could inhibit conditioned avoidance responding and also reduces fear-potentiated startle in rats and marble burying in mice. Importantly, it does not produce sedative effects or motor impairment in the conditioned avoidance task. It also increases dopamine and serotonin release/turnover in the prefrontal cortex. ^[4]
