Cyclosporin A Chemical Properties,Usage,Production
Immunosuppressants
Cyclosporin A is a lipophilic cyclic peptide compounds separated by certain Hyphomycetes fungi, such as Cylindrocarpon lucidum and Tolypocladium inflatumculture medium. In 1980s, as an immunosuppressant, it has been widely used in the world, is now used for a variety of tissues and organ transplant to prevent rejection reaction and to treat autoimmune diseases.
Cyclosporin A is a strong immunosuppressant, inhibits the onset of the reaction in cell media, reversibly inhibits T cell proliferation, does not inhibit the generation of blood cells, does not affect the function of the phagocyte. As compared with other inhibitors, fewer advantages are induce or aggravate infection, mainly used in clinical kidney, liver, heart, lung, bone marrow transplant anti-rejection, can be combined with adrenal corticosteroids, but not in combination with other immunosuppressive agents. Also used in certain autoimmune diseases (such as systemic lupus erythematosus, lupus nephritis, rheumatoid arthritis, autoimmune hemolytic anemia). Try to uveitis, severe aplastic anemia, refractory idiopathic thrombocytopenic purpura, psoriasis, etc.
Pharmacological effects
Cyclosporin A can reversibly selectively alter T-lymphocyte function, prevent transcription of lymphokine gene, interfere transfer of original information, inhibit the release of interleukin-2, interferon and other immune factors, affect humoral immunity and immune cells, inhibit killing viability of NK cell; inhibit differentiation and proliferation of lymphocyte in the antigen or mitogen stimulation. But no activity on bone marrow, very small effect on B cells, at therapeutic doses no significant inhibiting effect on granulocyte survival. Oral absorption is slow and incomplete, only 4% to 60%, an average is 30% of the administered dose; relative bioavailability is 20% to 50%. After 2~8h of oral administration reach its peak, with an average of 3.5h. Significant individual differences, such as the relative bioavailability of renal transplant patients is 5% to 89%, liver transplant patients is 8% to 60%. This product is fat-soluble drug, meals and eating food can increase the absorption of fat. Bile deficiency, stagnation, slow gastric emptying, increased gastric peristalsis, pancreatic dysfunction and steatorrhea, all affect absorption of the product.
Pharmacokinetics
Oral absorption is irregular and big differences in different individual, bioavailability is 30%, but can be increased with the extended duration of treatment and the increased dose. After liver transplantation, patients with liver disease or disorder of the gastrointestinal absorption may be reduced . Binding rate this product with plasma proteins is up to about 90%, mainly in combination with lipoproteins. Oral peak time is 3 to 4 hours, whole blood concentration is 2 to 9 times of plasma, adult plasma T1/2 is 19 (10-27) hours, while the child is only 7 (7 to 19) hours. This product is metabolized in the liver, by biliary excretion through feces, only 6% by renal excretion, of which about 0.1% is excreted in the primary form.
The above information is edited by the Chemicalbook of Liu Yujie.

Description
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.

Originator
Sandimmune,Sandoz,US,1983
Uses
An immunosuppressant that has revolutionized organ transplantation through its use in the prevention of graft rejection. A group of nonpolar cyclic oligopeptides with immunosupppressant activity.
Uses
prothrombogenic agent
Uses
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.

Therapeutic Function
Immunosuppressive
General Description
White prismatic needles (from acetone) or white powder.
Air & Water Reactions
Slightly water soluble .
Reactivity Profile
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.
Fire Hazard
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.
Pharmacology
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
Side effects
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.
Safety Profile
Confirmed carcinogen producing Hodghn's dlsease. Experimental reproductive effects. Poison by intraperitoneal and intravenous routes. Moderately toxic by ingestion. Human systemic effects by ingestion: increased body temperature, cyanosis. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.
Synthesis
Cyclosporine A, [R-[R* ,R* -(E)]]-cyclo-(L-alanyl-D-alanyl-N-methyl-Lleucyl-N-methyl-L-leucyl-N-methyl-L-valyl-3-hydroxy-N,4-dimethyl-L-2-amino-6- octenoyl-L-α-aminobutyryl-N-methylglycyl-N-methyl-L-leucyl-L-valyl-N-methyl-L-leucine) (31.2.2), is extracted from a cultural liquid of products of the vital activity of the mushroom Tolypocladium inflatum [14–17], and which is also proposed to obtain synthetically.

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.

Incompatibilities
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 such as hydrideds and active metals. 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 such as phosphorus pent- oxide or thionyl chloride generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
