Biological Activity

Description Azathioprine is an immunosuppressive drug, inhibiting purine synthesis and GTP-binding protein Rac1 activation, used in the treatment of organ transplantation and autoimmune diseases.
Rac1 [1]
In vitro

Azathioprine suppresses the activation of Rac1 target genes such as mitogen-activated protein kinase kinase (MEK), NF-kappaB, and bcl-x(L), leading to a mitochondrial pathway of apoptosis in primary human CD4+ T lymphocytes. Azathioprine thus converts a costimulatory signal into an apoptotic signal by modulating Rac1 activity. [1] Azathioprine-generated 6-Thio-GTP thus prevents the development of an effective immune response via blockade of Vav activity on Rac proteins. [2] Azathioprine (1 mM) restores ATP levels and arrests cell injury, while culture in glucose-enriched media augments ATP levels and ameliorates cell death. Azathioprine reduces viability 5-34% at day 1 and 42-92% by day 4. [3] Azathioprine decreases the viability of hepatocytes and induces the following events in primary culture of isolated rat hepatocytes: intracellular reduces glutathione (GSH) depletion, metabolic activity reduction, and lactate dehydrogenase release. Azathioprine effect on hepatocytes is associated with swelling and increased oxygen consumption of intact isolated rat liver mitochondria. [4]

In vivo Azathioprine combined with cyclosporin A and prednisolone has resulted in survival of 14 out of 15 grafts (93%), compared with 11 out of 14 (79%) in the group treated with cyclosporin A alone in mouse-rat brain xenograft. [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 (g) = Concentration (mol/L) × Volume (L) × 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.
