Biological Activity

Description Ivermectin is a glutamate-gated chloride channel (GluCls) activator, used as a broad-spectrum antiparasitic drug.
chloride channel [3]
In vitro

Ivermectin has potent antiviral activity towards both HIV-1 anddengue virus, both of which are strongly reliant on importin α/β nuclear import, with respect to the HIV-1 integrase and NS5 (non-structural protein 5) polymerase proteins respectively. [1] Ivermectin binds to a novel site on the GABAA receptor and allosterically enhances the affinity of the GABA binding site in mouse hippocampal embryonic neurons. [2] Ivermectin disrupts neurotransmission processes regulated by GluCl activity by binding to nematode glutamate-gated chloride channels (GluCls). Ivermectin decreases the amount of protein released from microfilariae. [3]

Sensitivity of GC cells to ivermectin. Cell viability was measured by MTT assays in GC cells treated with the indicated concentrations of ivermectin for 48 h. 

In vivo Ivermectin (1.25-10 mg/kg, intraperitoneal) significantly reduces 24-h alcohol consumption and intermittent limited access (4-hours) binge drinking, and operant alcohol self-administration (1-h). Ivermectin also produces a significant reduction in 24-h saccharin consumption, but does not alter operant sucrose self-administration. [4] Ivermectin improves mouse survival rate induced by a lethal dose of LPS. Ivermectin significantly decreases the production of TNF-alpha, IL-1ss and IL-6 in vivo and in vitro. Ivermectin suppresses NF-kB translocation induced by LPS. [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 (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.
