[CAS NO. 635318-11-5]  pomaglumetad (LY404039)

LY404039 demonstrates higher plasma exposure and better oral bioavailability. LY404039 may be valuable in the treatment of neuropsychiatric disorders, including anxiety and psychosis. In wild-type animals, LY404039 significantly reverses d-amphetamine(AMP)-induced increase in ambulations, distance traveled, and reduced time spent at rest. LY404039 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. LY404039 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. LY404039 inhibits the expression of alcohol seeking and relapse behavior without altering alcohol self-administration behavior. Moreover, LY404039 attenuates amphetamine- and phencyclidine-induced hyperlocomotion. LY404039 could inhibit conditioned avoidance responding and also reduces fear-potentiated startle in rats and marble burying in mice. Importantly, LY404039 does not produce sedative effects or motor impairment in the conditioned avoidance task. LY404039 also increases dopamine and serotonin release/turnover in the prefrontal cortex.
