| Targets |

|
| In vitro |
Zonisamide inhibits monoamine oxidase B (MAO-B) activity in vitro with an IC(50) of 25 μM. [1] |
|
| In vivo | Zonisamide modifies dopamine (DA) activity, provides protection in ischemia mice models and influences antioxidant systems. Zonisamide attenuates the reduction in striatal contents of DA, its metabolite DOPAC and tyrosine hydroxylase (TH). [1] Zonisamide (10 and 30 mg/kg) produces antihyperalgesic and antiallodynic effects in a dose-dependent manner, these effects are manifested by elevation of the withdrawal threshold in response to a thermal (plantar test) or mechanical (von Frey) stimulus, respectively.. Zonisamide produces antinociceptive effects against acute thermal and mechanical nociception in non-ligated mice. [2] Zonisamide reduces the cortical infarction volume to 6% from 68% in vehicle-treated controls and the striatal volume to 8% from 78% in rats. Zonisamide also reduces neuronal necrosis in 5 hippocampal regions (the dentate gyrus, CA4, CA3, CA1, and the subiculum) in rats. [3] Zonisamide causes increase in the quantity of EAAC-1 protein in hippocampus and cortex and down regulation of the GABA transporter GAT-1 in rats with hippocampal seizures. [4] Zonisamide inhibits both the 50 mM KCl-evoked hippocampal glutamate release (AUC for 60 min) from 9.2 mM to 5.8 mM in urethane-anaesthetized rats, as well as the stimulatory effects of Ca2+ on KCl-evoked hippocampal glutamate release.

Bio Calculators
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)
*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
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.
