|Description||Vilazodone HCl is a selective serotonin reuptake inhibitor (SSRI) and a partial agonist of 5-HT1A receptors, used for the treatment of major depressive disorder.|
Vilazodone demonstrates an IC50 of 0.2 nM at the human 5-HT1A receptor and 0.5 nM for the SERT. Vilazodone displays high affinity (pKi ≥ 9.3) for human recombinant and rat, guinea pig, mouse, and marmoset native tissue 5-HT1A receptors. 
|In vivo||Vilazodone selectively enhances serotonergic output in the prefrontal cortex of rats. Vilazodone demonstrates anxiolytic efficacy through Behavioral evaluations in the ultrasonic vocalization model of anxiety in rats. Vilazodone also shows efficacy but at a single dose only in the forced swim test (a putative model of depression).  Vilazodone (1-10 mg/kg p.o.) dose-dependently displaces in vivo [3H]DASB (N,N-dimethyl-2-(2-amino-4-cyanophenylthio)benzylamine) binding from rat cortex and hippocampus, indicating that vilazodone occupies 5-HT transporters in vivo. Vilazodone (10 mg/kg p.o.) is demonstrated to cause a 2-fold increase in extracellular 5-HT but no change in noradrenaline or dopamine levels in frontal cortex of freely moving rats.  Vilazodone affects stress potentiation of startle at doses above 5 mg/kg in rats. Vilazodone increases stress elevation of startle at 10 mg/kg in rats. Vilazodone (20 and 40 mg/kg) blocked stress potentiation of startle in rats. Vilazodone increases stress elevation of startle at all doses in rats.  vilazodone has no effect on 5-HT efflux at 100 nM but significantly decreases 5-HT efflux at 1 mM in the guinea-pig dorsal raphe nucleus. Vilazodone significantly increases the re-uptake half life for 5-HT in the guinea-pig dorsal raphe nucleus. |

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

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 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.
