  • Olanzapine and aripiprazole differentially regulate cellular glucose uptake of PBMC. Bar graphs depict cellular glucose uptake assessed by 18F-FDG in PBMC after 72 h of stimulation with the indicated concentrations of olanzapine (Olan, A) or aripiprazole (Arip, B) relative to corresponding DMSO controls (Ctrl) and normalized to protein content. Data are depicted as mean ± SD. P-values were computed by one-way ANOVA followed by Dunnett's Multiple Comparison Test. ***P < 0.001, **P < 0.01, *P < 0.05 versus control; results were obtained from n = 4e-6 independent cell isolations measured in duplicate

Biological Activity

Description Aripiprazole is a novel atypical antipsychotic drug that is reported to be a high-affinity 5-HT receptor partial agonist.
5-HT1A [1]
4.2 nM(Ki)
In vitro

Aripiprazole binds with high affinity to both the G protein-coupled and uncoupled states of receptors. Aripiprazole potently activates D2 receptor-mediated inhibition of cAMP accumulation. [1] Aripiprazole has highest affinity for h5-HT(2B)-, hD(2L)-, and hD(3)-dopamine receptors, but also has significant affinity (5-30 nM) for several other 5-HT receptors (5-HT(1A), 5-HT(2A), 5-HT(7)), as well as alpha(1A)-adrenergic and hH(1)-histamine receptors. Aripiprazole has less affinity (30-200 nM) for other G protein-coupled receptors, including the 5-HT(1D), 5-HT(2C), alpha(1B)-, alpha(2A)-, alpha(2B)-, alpha(2C)-, beta(1)-, and beta(2)-adrenergic, and H(3)-histamine receptors. Aripiprazole is an inverse agonist at 5-HT(2B) receptors and displays partial agonist actions at 5-HT(2A), 5-HT(2C), D(3), and D(4) receptors. [2]

In vivo Aripiprazole reduces extracellular 5-HIAA concentrations in the medial prefrontal cortex and striatum of drug-naive rats, but not in chronic Aripiprazole-pretreated rats. [3] Aripiprazole, 0.1 mg/kg and 0.3 mg/kg, significantly increases dopamine release in the hippocampus of rats. Aripiprazole, 0.3 mg/kg, slightly but significantly increases dopamine release in the medial prefrontal cortex but not in the nucleus accumbens. Aripiprazole, 3.0 mg/kg and 10 mg/kg, significantly decreases dopamine release in the nucleus accumbens but not the medical prefrontal cortex. Aripiprazole, 0.3 mg/kg, transiently potentiates haloperidol (0.1 mg/kg)-induced dopamine release in the medial prefrontal cortex but inhibited that in the nucleus accumbens. [4]

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*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).

Dilution Calculator

Dilution Calculator

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 )

  • C1

* 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.
