Product Description

Escitalopram Oxalate (Cipralex; Lexapro; Lu10171; Lu-10171; Citalopram;Cytalopram), the oxalate salt of Escitalopram which is an approved antidepressant drug, is a potent and selective serotonin (5-HT) reuptake inhibitor (SSRI) with a Ki of 0.89 nM. Escitalopram Oxalate is the citalopram S-(+)-enantiomer. It has the ability to block [3H]-5-HT uptake and [125I]-RTI-55 binding in COS-1 cells that express the 5-HTT human serotonin transporter, with Ki values of 3.9±2.2nM and 6.6±1.4nM, respectively.

Targets
serotonin transporter ( Ki = 0.89 nM ); DAT ( Ki = 10500 nM ); NET ( Ki = 8150 nM )
ln Vitro

In vitro activity: Escitalopram, the citalopram S-enantiomer, is an antidepressant that is categorized as a selective serotonin-reuptake inhibitor (SSRI). It is applied to the treatment of depression related to mood disorders. It is also used on occassion in the treatment of body dysmorphic disorder and anxiety. Escitalopram is thought to have these effects because it inhibits serotonin uptake by CNS neurons, which in turn has antidepressant, antiobsessive-compulsive, and antibulimic properties.[1] In vitro studies show that escitalopram is a potent and selective inhibitor of neuronal serotonin reuptake and has only very weak effects on norepinephrine and dopamine neuronal reuptake. Escitalopram does not significantly bind to adrenergic (alpha1, alpha2, beta), cholinergic, GABA, dopaminergic, histaminergic, serotonergic (5HT1A, 5HT1B, 5HT2), or benzodiazepine receptors. It is hypothesized that antagonistic interactions with these receptors cause a variety of anticholinergic, sedative, and cardiovascular effects when used with other psychotropic medications. As has been seen with other medications that are beneficial in treating major depressive disorder, escitalopram is found to downregulate brain norepinephrine receptors when administered chronically. scitalopram is not a monoamine oxidase inhibitor.[2]

Water: ~25 mg/mL (~60.3 mM)
Ethanol: <1 mg/mL
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 100 mg/mL (241.30 mM) (saturation unknown) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 2.4130 mL 12.0648 mL 24.1295 mL
5 mM 0.4826 mL 2.4130 mL 4.8259 mL
10 mM 0.2413 mL 1.2065 mL 2.4130 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
