A cyclic undecapeptide from an extract of soil fungi. It is a powerful immunosupressant with a specific action on T-lymphocytes. It is used for the prophylaxis of graft rejection in organ and tissue transplantation. Cyclosporine is produced as a metabolite by the fungus species Cordyceps militaris. Cyclosporin A inhibits calcineurin with IC50 of 7 nM, then blocks the nuclear translocation of NF-AT. Cyclosporin A also affects mitochondria by preventing the MTP (mitochondrial permeability transition pore) from opening with an IC50 of 39 nM.
