LY404039 avoids reduction in phospho-Akt levels caused by DETA/NO. Total cellular proteins were extracted as described in Materials and Methods from astrocytes exposed to 1 mM DETA/NO6100 mM LY40403961 mM db-cAMP for 30 min, and 50 mg of protein extracts were assayed for phospho-Akt by western-blot. (A) Specificity of the western-blot was analyzed by incubating astrocytes with the PI3K/Akt pathway inhibitor, 20 mM LY294002, which completely prevented LY404039-induced Akt phosphorylation, and LPS/IFNc was used as positive control of Akt activation. Membranes were stripped and incubated with anti-total Akt antibody, which was considered loading control. (B) Data were expressed as phospho-Akt/ total Akt ratio and related to control group. Bars represent the mean 6 SEM of 4 independent experiments. *p,0.05, ***p,0.001 versus control, ‘‘p,0.01 versus LY404039.

|Description||LY404039 is a potent agonist of recombinant human mGlu2/mGlu3 receptors with Ki of 149 nM/92 nM, shows >100-fold selectivity over ionotropic glutamate receptors, glutamate transporters, and other receptors. Phase 3.|
|Features||Under investigation as an exciting new medicine that may herald the arrival of third-generation antipsychotic drugs.|
LY404039 exhibits low binding affinity to group III mGlu receptors including mGlu6, mGlu7 and mGlu8 with a Ki value more than 5 μM. LY404039 shows little affinity for ionotropic glutamate receptors, glutamate transporter subtypes, monoamine and other receptors. LY404039 potently inhibits forskolin-stimulated cAMP formation in cells expressing human mGlu2 and mGlu3 receptors. LY404039 suppresses electrically evoked excitatory activity in the striatum, and serotonin-induced L-glutamate release in the prefrontal cortex. LY404039 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. 
|In vivo||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. |

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
