Biological Activity

Description Lamotrigine is a novel anticonvulsant drug for inhibition of 5-HT with IC50 of 240 μM and 474 μM in human platelets and rat brain synaptosomes, and also is a sodium channel blocker.
Targets
Sodium channel [1] 5-HT (human platelets) [1] 5-HT (rat brain synaptosomes) [1]
240 μM 474 μM
In vitro

Lamotrigine stabilises presynaptic neuronal membranes by blockade of voltage-dependent sodium channels, thus preventing the release of excitatory neurotransmitters, particularly glutamate and aspartate. [1] In rat cerebral cortex tissue incubated with veratrine 10 mg/L, lamotrigine is twice as potent in inhibiting the release of glutamate and aspartate (ED 50 = 5.38 mg/L for each) than the release of GABA (ED50 = 11.2 mg/L), and is much less potent in inhibiting acetylcholine release (ED50 = 25.6 mg/L) when cortical slices is exposed to veratrine 75 mg/L. Basal glutamate release is unaffected . [2]Lamotrigine inhibits high-frequency sustained repetitive firing of sodium-dependent action potentials, indicating a direct effect on voltage-activated sodium channels. [3] Lamotrigine does not induce PCP-like central nervous system (CNS) effects, does not act by direct inhibition at the NMDA receptor, and would be expected to be devoid of the undesirable effects associated with NMDA blockade. [4]

In vivo In mice and rats, lamotrigine prevents MES- and pentetrazol-induced hindlimb extension, suggesting an antiepileptic profile in animals. These effects peak 1 hour after lamotrigine administration and persist for more than 24 hours. [4] Lamotrigine is active in the electrically evoked EEG after-discharge test, which is thought to indicate activity against both simple and complex partial seizures. After-discharge duration is reduced dose-dependently by lamotrigine in rats at intravenous doses >5 mg/kg. [5]

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)

*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 )

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.
