Biological Activity

Description Ethosuximide is a succinimide anticonvulsant, used mainly in absence seizures; A calcium channel blocker.
In vitro

Ethosuximide(ETH) enhances hippocampal derived NSC proliferation and neurospheres formation in vitro. Low concentration of ETH induces proliferation of NSC, while higher concentrations of ETH are cytotoxic. Also, ETH activates the PI3K/Akt signal transduction pathway in adult hippocampal NSC in vitro. Blockade of the PI3K/Akt pathway inhibits ETH induced hippocampal NSC neuronal differentiation[3].

In vivo Anti-epileptic drug ethosuximide rescues the short lifespan and chemosensory defects exhibited by C. elegans null mutants of dnj-14, the worm orthologue of the DNAJC5 gene mutated in autosomal-dominant adult-onset neuronal ceroid lipofuscinosis. It also ameliorates the locomotion impairment and short lifespan of worms expressing a human Tau mutant that causes frontotemporal dementia[1]. Ethosuximide extends lifespan by inhibiting the function of specific chemosensory neurons[2]. It increases neurogenesis, reduces neurodegeneration, and reverses cognitive impairments in rat model of AD like phenotypes[3].


Cell Research:


- Collapse
  • Cell lines: Mouse neuroblastoma cell line (N2A)
  • Concentrations: 0.1, 0.56, 1 mg/ml
  • Incubation Time: 5 h
  • Method:

    Mouse Neuro2A (N2A) neuroblastoma cells are cultured on 6-well plates and treated with retinoic acid to induce neuronal differentiation. After 24 h, N2A cells are treated with vehicle control (PBS) or increasing concentrations of ethosuximide for 5 h. Total RNA is then isolated, DNase-treated and reverse transcribed to cDNA. qRT-PCR is run above normalising to the reference genes glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and β-actin (ACTB).

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 (mg) = Concentration (mM) × Volume (mL) × 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 SDS / 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 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.
