Biological Activity

Description Cyclosporine (NSC-290193) 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]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
