Biological Activity

Description Levocetirizine is the active R-enantiomer of cetirizine and represents a new second-generation histamine H1 antagonist.
H1 receptor [1]
In vitro

Levocetirizine is a selective antihistaminic that acts through H1 receptor. Levocetirizine inhibits eotaxin-induced eosinophil transendothelial migration through monolayers of human dermal or lung microvascular endothelial cells in vitro. The drug also inhibits both resting and granulocyte-macrophage colony-stimulating factor (GM-CSF)-stimulated eosinophil adhesion to vascular cell adhesion molecule-1 (VCAM-1), eotaxin production by endothelial cells and ICAM-1, as well as major histocompatability complex (MHC) class I expression by interferon (IFN)-γ-stimulated keratinocytes[1].

In vivo In vivo, levocetirizine has rapid absorption and high bioavailability, a low potential for drug interactions, low-volume distribution and a lack of effects on cognition, psychomotor function or the cardiovascular system[1]. Levocetirizine improves renal function in diabetic rat. It attenuates the elevated renal levels of TNF-α and TGF-β1, ameliorates renal oxidative stress and restores NO bioavailability in diabetic kidney. Levocetirizine elicits vasculoprotective and renoprotective effects in experimental diabetes[2].

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.
