Biological Activity

Description Granisetron is a serotonin 5-HT3 receptor antagonist,used to treat chemotherapy-induced nausea and vomiting.
5-HT3 [1]
In vitro

Granisetron blocks the delayed rectifier current (IK) of feline isolated ventricular myocytes with a KD of 4.3 mM. Granisetron shows an intrinsic voltage-dependence as the block increases with depolarization. Granisetron blocks from the intracellular side at a binding site located 10% across the transmembrane electrical field. Granisetron (3 mM) prolongs the action potential duration (APD) by about 30% at 0.5 Hz in feline isolated ventricular myocytes. [1] Granisetron but not Ondansetron, could prevent the activation of putative 5-H; autoreceptors, thus leading to a decrease in serotonin release by the enterochromaffin cells. [2]

In vivo Granisetron provides a substantial benefit against cisplatin-induced emesis in the piglet, some animals being completely protected during both the acute and the delayed phases. [2] Granisetron (1 mg/kg, i.m.) administered three times per day reduces significantly the retching+vomiting response induced by cisplatin on days 1 and 2 by 100.0% and 75.0%, respectively, in cats. [3] Granisetron or dexamethasone significantly improves macroscopic and histologic scores, curtails myeloperoxidase activity and diminishes colonic levels of inflammatory cytokines and malondialdehyde in rats. [4] Granisetron, not only prevents cholera toxin-induced jejunal net fluid secretion but also, and in proportion, inhibits 5-HT release into the intestinal lumen of mice. [5]

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

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 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.
