Biological Activity

Description Cyclosporine is a calcineurin phosphatase pathway inhibitor, used as an immunosuppressant drug to prevent rejection in organ transplantation.
calcineurin phosphatase [2]
In vitro

Cyclosporine induces phenotypic changes, including invasiveness of non-transformed cells, by a cell-autonomous mechanism. Cyclosporine treatment of adenocarcinoma cells results in striking morphological alterations, including membrane ruffling and numerous pseudopodial protrusions, increased cell motility, and anchorage-independent (invasive) growth. [1] Cyclosporine (cyclosporin A, CsA) has potent immunosuppressive properties, reflecting its ability to block the transcription of cytokine genes in activated T cells. Cyclosporine through formation of a complex with cyclophilin inhibits the phosphatase activity of calcineurin, which regulates nuclear translocation and subsequent activation of NFAT transcription factors. Cyclosporine also blocks the activation of JNK and p38 signaling pathways triggered by antigen recognition, making CsA a highly specific inhibitor of T cell activation. [2] Cyclosporine-mediated inhibition of the biliary excretion of MPAG by the Mrp2 transporter is the mechanism responsible for the interaction between Cyclosporine and mycophenolate mofetil (MMF). [3] Cyclosporine inhibits biochemical and morphological differentiation of skeletal muscle cells while having a minimal effect on proliferation. [4]

In vivo Cyclosporine enhances tumour growth in immunodeficient SCID-beige mice. [1] Cyclosporine inhibits muscle regeneration after induced trauma in mice. [4] Cyclosporine peaks at 1 hour in blood, spleen, and kidney, with higher concentrations in spleen and kidney than in blood. [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.
