|Description||Risperidone (R-64766) is a mutil-targeted antagonist for dopamine, serotonin, adrenergic and histamine receptors, used to treat schizophrenia and bipolar disorder.|
Risperidone binds to both DA and serotonin (5HT) receptors, particularly in the neurons of striatal and limbic structures. Risperidone significantly affects brain nerve growth factor (NGF) level suggesting that it influences the turnover of endogenous growth factors. Risperidone significantly decreases BDNF concentrations in frontal cortex, occipital cortex and hippocampus and decreases or increases TrkB receptors in selected brain structures.  Risperidone significantly increases D(2) binding in medial prefrontal cortex by 34% in rat forebrain regions. Risperidone produces even greater up-regulation of D(4) receptors in CPu (37%), NAc (32%), and HIP (37%) in rat forebrain regions.  Risperidone significantly inhibits the production of NO and proinflammatory cytokines by activated microglia.  Risperidone (1-50 mM) significantly enhances the intracellular accumulation of Rh123 in Caco-2 cells by inhibiting P-gp activity with an IC(50) value of 5.87 mM. 
Risperidone does not significantly affect bodyweight gain (BWG), food intake(FI), glucose tolerance or leptin levels, even though prolactin and corticosterone are significantly elevated in male rats. Risperidone significantly increases BWG and FI in female rats.  Risperidone (0.05 mg/kg) increases food intake and leptin gene expression in white adipose tissue (WAT), but the rate of bodyweight gain is not affected in rats. Risperidone (0.5 mg/kg) causes a reduction in bodyweight gain, as well as enhanced Ucp1 gene expression in BAT and serum prolactin concentrations in rats.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
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 MSDS / 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 MSDS / 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.
