Biological Activity

Description Cinnarizine (Stugeron, Dimitronal, Stutgin, Cinarizine) is a medication derivative of piperazine, and characterized as an antihistamine and a calcium channel blocker.
Calcium channel [1] Histamine receptor [3]
In vitro

Cinnarizine inhibits melanogenesis in B16 cells by a dose-dependent manner at the non-cytotoxic concentrations and is a histamine receptor antagonists[3].

In vivo Cinnarizine has anticonvulsive properties in rats and mice. It could provide a direct neuroprotective effect against the damaging influx of calcium and also prevent neuronal damage as a result of MES- and PTZ-induced seizures[2]. Cinnarizine induces behavioural changes such as alopecia, bucolingual dyskinesia and reduction of motor activity in female parkin knock out (PK-KO) mice but not in wild-type (WT) controls.PK-KO mice have high striatal dopamine levels and increased dopamine metabolism in spite of low reduced tyrosine hydroxylase protein. Cinnarizine, which blocks dopamine receptors and increases dopamine release, further increased dopamine metabolism[3]. Its half-life is 4 hours.


Cell Research:[4]
- Collapse
  • Cell lines: mouse B16 melanoma cells(4A5)
  • Concentrations: 0.625, 1.25, 2.5, 5, 10, 20 μM
  • Incubation Time: 48 h
  • Method: MTT assay is performed to examine the viability of cells. Afterwards, the cells are incubated with the samples for 48 h, the culture medium is removed and replaced with 1 mg/mL MTT solution dissolved in phosphate-buffered saline (PBS) and incubated for an additional 2 h. The MTT solution is then removed and DMSO was added, following which the absorbance of the dissolved formazan crystals is determined at 570 nm by a spectrophotometer.

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.
