    Description

    Cyclosporin A is an immunosuppressant which binds to the cyclophilin and inhibits phosphatase activity of calcineurin with an IC50 of 5 nM.

    IC50 & Target

    IC50: 7 nM (calcineurin)

    In Vitro

    Cyclosporin A is able to bind with the cyclophilin in T cells[1]. Cyclosporin A works by forming a Cyclophilin-Cyclosporin A complex to inhibit calcineurin[2]. Cyclosporin A exhibits inhibitory effect on calcineurin with an IC50 of 7 nM[3]. Cyclosporin A suppresses the nuclear translocation of NF-AT[4]. Cyclosporin A shows an effect on mitochondria via preventing the MTP from opening with an IC50 of 39 nM[5].

    In Vivo

    Cyclosporin A has immunosuppressive activity, and is active via parenteral and p.o. administration in mice, rat and guinea pigs[6]. Cyclosporin A can be used in organ transplantation to prevent rejection[7].

    [3]

    Reaction mixtures with purified enzyme contains 100 nM calcineurin, 100 nM calmodulin, and 5 μM 32P-labeled phosphopeptide, in 60 μL (total volume) of assay buffer containing 20 mM Tris (pH 8), 100 mM NaCl, 6 mM MgCl2, 0.5 mM dithiothreitol, 0.1 mg of bovine serum albumin per mL, and either 0.1 mM CaCl2 or 5 mM EGTA. Reaction mixtures with cell lysates contains 20 μL of undiluted lysate, 5 μM 32P-labeled phosphopeptide, and 40 μL of assay buffer. Reaction mixtures contains 50 μM peptide 412 or 413 and/or 500 nM okadaic acid, a specific inhibitor of phosphatases 1 and 2A; 500 nM okadaic acid is sufficient for inhibition of Ca2+-independent phosphatases, whereas higher concentrations partially inhibit Ca2+-dependent activity as well. After 15 min at 30°C, reactions are terminated by the addition of 0.5 mL of 100 mM potassium phosphate buffer (pH 7.0) containing 5% trichloroacetic acid. Free inorganic phosphate is isolated by Dowex cation-exchange chromatography and quantitated by scintillation counting as described.

    Cell Assay
    [3]

    Immunosuppressive agents are dissolved in ethanol at concentrations 1000-fold more than the concentration desired for cell treatments. Cells (106) are suspended in 1 mL of complete medium in microcentrifuge tubes; 1 μL of ethanol or of the ethanolic solution of Cyclosporin A is added, and the cells are incubated at 37°C for 1 hr. Cells are washed twice with 1 mL of PBS on ice and lysed in 50 μL of hypotonic buffer containing 50 mM Tris (pH 7.5); 0.1 mM EGTA; 1 mM EDTA; 0.5 mM dithiothreitol; and 50 μg of phenylmethylsulfonyl fluoride, 50 μg of soybean trypsin inhibitor, 5 μg of leupeptin, and 5 μg of aprotinin per mL. Lysates are subjected to three cycles of freezing in liquid nitrogen followed by thawing at 30°C and then are centrifuged at 4°C for 10 min at 12,000×g.

    Animal Administration
    [6]

    Rats are immunized on day 0 i.p. with 0 5 mL and mice i.v. with 0 2 mL of a 10% suspension of washed sheep erythrocytes (SE). To elicit a secondary response, mice are boosted 8-11 weeks after the primary immunization with an i.v. injection of 0-2 mL of 0 25% washed SE (107 cells). For prolonged treatment the animals receive on the average 45 mg/kg cyclosporin A daily in the food during 13 weeks. These rats are immunized 5 days before killing.
