• Beschreibung

  Cyclosporine A is a powerful immunosuppressive drug intended for preventing rejection of kidney, heart, and lung transplants. A new era in the development of immunopharmacology began with the discovery of cyclosporines. Cyclosporines are produced by mycelial mushrooms Tolypocladium inflatum, Tricoderma polysporum, and Cylindrocarpon lucidum, which are found in the ground.
  Cyclosporine A is the first drug to affect a specific line of protecting cells of the body. Unlike usual cytotoxics, it suppresses T-cells and acts on all cell lines simultaneously. Cyclosporine A significantly eases the ‘reception’ of transplants, and increases the possibility of treating autoimmune system diseases.

• Verwenden

  Cyclosporin A is a hydrophobic cyclic peptide isolated from several fungal species including Cylindrocarpon, Fusarium, Trichoderma and Tolypocladium. Cyclosporin A inhibits T-cell activation and has been marketed since 1983 as an immunosuppressant in post-allogeneic organ transplant. Cyclosporin A acts by binding to the protein, cyclophilin (immunophilin), in T-lymphocytes causing inhibition of calcineurin (protein phosphatase 2B). Cyclosporin A reduces transcription of interleukin 2, and inhibits lymphokine production, interleukin release and NO synthesis induced by interleukin 1α, lipopolysaccharides and TNFα.

• Definition

  ChEBI: A cyclic nonribosomal peptide of eleven amino acids; an immunosuppressant drug widely used in post-allogeneic organ transplant to reduce the activity of the patient's immune system, and therefore the risk of organ rejection. Also causes reversible inhibiti n of immunocompetent lymphocytes in the G0- and G1-phase of the cell cycle.

• Indications

• Manufacturing Process

  10 liters of a nutrient solution (of which each liter contains 30 g of sucrose, 10 g of corn steep, 3 g of NaNO3, 1 g of K2HPO4, 0.5 g of MgSO4·7H2O, 0.5 g of KCl and 0.01 g of FeSO4·7H2O) are inoculated with 100 cc of a conidia and mycelium suspension of the strain NRRL 5760, and incubation is effected in 700 cc penicillin flasks at 27°C for 11 days.
  The mycelium, which has been separated from the culture liquid, is extracted in a Turrax apparatus by crushing and stirring with 3.5 liters of 90% methanol, and the crushed mycelium, which is separated from the solvent by filtering with suction, is again treated twice in the same manner with 90% methanol. The combined filtrates are concentrated by evaporation in a vacuum at a bath temperature of 40°C to such an extent that the vapor mainly consists of water alone. The resulting mixture is extracted six times with the same volume of ethylene chloride by shaking, whereupon the combined ethylene chloride solutions are purified by extraction with water and are concentrated by evaporation in a vacuum at a bath temperature of 40°C. The resulting residue is chromatographed on 250 g of silica gel (silica gel 60 Merck, grain size 0.063-0.200 mm), using chloroform containing 2% of methanol as eluant, and is collected in 200 cc fractions. The fractions which are antibiotically active against Aspergillus niger in the plate diffusion test are combined, evaporated to dryness as described above, and after dissolving in methanol are chromatographed on 110 g of Sephadex LH20 with the same solvent, whereupon those 20 cc fractions showing an antibiotic effect against Aspergillus niger in the test indicated above, are combined. A test in the thin layer chromatogram, e.g., with silica gel on Polygram foils and hexane/acetone (1:1) as eluant, indicates that the residue of the methanol solution evaporated as described above mainly consists of the two new antibiotics S 7481/F-1 and S 7481/F-2. These are separated and simultaneously purified by a further chromatography of the mixture thereof, using a 1,000-fold amount of silica gel on the above indicated quality and chloroform contains 2% of methanol. A testing of the eluate fractions having a volume in milliliters which is half as large as the weight of the silica gel in grams, in the thin layer chromatogram, indicates that the antibiotic S 7481/F- 1 appears first in the eluate, followed by a mixture of the two antibiotics and finally by homogeneous S748l/F-2.
  Further amounts of the two antibiotics may be obtained from the mixture by repeating chromatography under the same conditions.

• Reaktivität anzeigen

  Cyclosporin A is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

• Health Hazard

  SYMPTOMS: Symptoms of exposure to Cyclosporin A include hepatotoxicity, nephrotoxicity, hyperkalemia, hyperuricemia, convulsions, renal dysfunction, tremor, hirsutism, hypertension, gum hyperplasia, cramps, acne, headache, diarrhea, nausea, vomiting, abdominal discomfort, paresthesia, flushing, leukopenia, lymphoma, sinusitis and gynecomastia. In 2% or less of persons exposed, it has caused allergic reactions, anemia, anorexia, confusion, conjunctivitis, edema, fever, brittle fingernails, gastritis, hearing loss, hiccups, hyperglycemia, muscle pain, peptic ulcer, thrombocytopenia and tinnitus. Rare reactions include anxiety, chest pain, constipation, depression, hair breaking hematuria, joint pain, lethargy, mouth sores, myocardial infarction, night sweats, pancreatitis, pruritus, swallowing difficulty, tingling, upper gastrointestinal bleeding, visual disturbance, weakness and weight loss. It has caused kidney and liver damage. An increased susceptibility to infection may occur. Other symptoms include gastrointestinal disturbance, rashes and angioedema.

  Flash point data for Cyclosporin A are not available; however, Cyclosporin A is probably combustible.

• Biochem/physiol Actions

  Cyclosporin A is a non-polar cyclic oligopeptide produced by the fungus Tolypocladium inflatum. It is a potent immunosuppressive agent, affecting primarily T-lymphocytes. It has been shown to inhibit the functioning of several nuclear proteins involved in T-cell activation at the level of mRNA transcription. It forms a complex with its intracellular receptor cyclophilin, which can then bind to calcineurin, a Ca2+- and calmodulin-dependent protein phosphatase, inhibiting its enzymatic activity. CsA was found to suppress the replication of hepatitis C virus genome in cultured hepatocytes. At concentrations >10 nM, CsA protected isolated hepatocytes against the action of phalloidin. CsA can inhibit IL2 production resulting from T cell activation via Calcineurin inhibition.An extensive list of references has been reported, including a comprehensive review of analytical properties.

• Pharmakologie

  Cyclosporine has no direct effect on keratinocytes and is not a mitotic inhibitor. Cyclosporine inhibits cytokine release, which results in a decreased recruitment of APCs into the epidermis and decreases immunoreactivity of lesions. Potential long-term side effects preclude cyclosporine’s use in all but very severe and recalcitrant psoriasis. Cyclosporine can be combined with lowdose methotrexate.

• Clinical Use

  Immunosuppressant:
  Prophylaxis of solid organ transplant rejection
  
  Nephrotic syndrome
  
  Atopic dermatitis
  
  Psoriasis
  
  Rheumatoid arthritis
  
  Ulcerative colitis

• Nebenwirkungen

  Cyclosporine’s main side effects, even at low doses, are hypertension and nephrotoxicity. Age, baseline blood pressure, and baseline creatinine levels are predictors of higher risks of side effects. Glomerular filtration rate (GFR) is a more sensitive test than creatinine for evaluating renal function, and a baseline is recommended in any high-risk patient. Longterm treatment with CSA may induce interstitial fibrosis and glomerular sclerosis, with more pronounced changes directly associated with duration of therapy. It should be administered only by dermatologists experienced in its use.

• Carcinogenicity

  Cyclosporin A is known to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in humans.

• Stoffwechsel

  Ciclosporin is widely distributed throughout the body. Distribution in the blood is concentration-dependent, with between 41-58% in erythrocytes and 10-20% in leucocytes; the remainder is found in plasma, about 90% protein-bound, mostly to lipoprotein.
  Clearance from the blood is biphasic. Ciclosporin is extensively metabolised in the liver and mainly excreted in faeces via the bile. About 6% of a dose is reported to be excreted in the urine, less than 0.1% unchanged.
