What is Cyclosporine?

99% Cyclosporine Powder Of Best Prices In China

Cas number: 59865-13-3

Molecular formula: C62H111N11O12

Molecular weight: 1202.6 g/mol

HS code: 2933990099

As the main-stream immunosuppressant raw material, cyclosporine is s a white to off-white crystalline solid with a very weird skunk smell.

It is soluble in acetone and methanol, slightly soluble in water.

It is one of our GMP Approved APIs along with tacrolimus powder and sirolimus (Rapamycin).

Cyclosporine is a polypeptide with eleven amino acids, and they form a circle.

This is also where the ‘cyclo’ within cyclosporine comes from.

Some people also call it ciclosporine, cyclosporin, and cyclosporin A, actually they are the same thing.

Doctors often prescribe its tabs or caps for patients with organ transplants, as it can effectively reduce the activity of the patient’s immune system, so to lower the risks of organ rejections.

People also use it to treat rheumatoid arthritis, psoriasis, Crohn’s disease, nephrotic syndrome.

Cyclosporine is also made into eye drops to relieve the symptoms of dry eyes.

How Is Cyclosporine Powder Manufactured?

1. Fermentation

Tolypocladium inflatum Cams are used as the production strain.

Fill a 75L tank with a 50L fermentation medium, inoculated with 5×109 spores.

Adjust the PH value of medium to 5.4-4.3, and cultivate it for 72h to get the primary solution.

Fill a 750L fermentation tank with a 500L medium, seed it with the above primary solution.

Culture it for 6 days to get the secondary solution.

Fill a 4500L tank with a 3000L medium, get it fermented for 12 days, and then we get cyclosporine fermentation broth.

2. Separation

Add an equal volume of ethyl acetate to the fermentation broth to separate the organic layer by extraction.

We separate it by evaporating the mixture under reduced pressure, and then we get the crude product.

In the crude product, we can get cyclosporine and cyclosporine C, where the yield of cyclosporine is about 150-200mg/L cyclosporine C is about 50-100mg/L.

Those two components are further separated by HPLC.

Then the pure powder of cyclosporine is collected by crystalization.

What Is Cyclosporine Used For?

1. Immunosuppressive agents

Clinically cyclosporine is mainly used as the immunosuppressive agents for patients with transplant.

It is used to prevent the rejection of allogeneic kidney, liver, heart, bone marrow and other organs or tissues transplantation

Also it is used for the prevention and treatment of graft-versus-host reaction in bone marrow transplantation.

2. Treatment of Immune diseases

It is also used together with adrenocorticotropic hormone for the treatment of some immune diseases.

3. New explorations

in recent years, it has been reported to be used in the treatment of uveitis, heavy aplastic anemia and refractory autoimmune thrombocytopenic purpura, psoriasis, refractory lupus nephritis, etc.

Is Cyclosporine Dangerous?

#1. Safety issues as a chemical:

Chemically speaking, cyclosporine powder is tested and categorized as a very safe and common chemical to be shipped by air or by express. All the shipping companies such as FedEx, TNT, DHL and UPS are shipping it every day.

It is non poisonous and we can tell that by its LD50 of value by oral intake:

LD50 in rats by oral is 1480mg/kg

LD50 in mice by oral is 2803mg/kg

LD50 in rabbits by oral is over 1000mg/kg.

LD50 by Intravenous injection:

LD50 for rats by injection is 25mg/kg

LD50 for mice by injection is 107mg/kg

LD50 for rabbits by injection is over 10mg/kg.

It is neither flammable or explosive in any way.

Its flash point is 736.3°C and boiling point as 1293.8°C.

It is relatively stable for heat.

For more safety details, you can check its msds data below in download section.

#2. Side effects as a drug:

1. Nephrotoxicity:

One of its most severe side effects is nephrotoxicity, which might be related to the susceptibility of the individual.

It may affect renal function, decrease the ability of glomerular filtration rate, and cause high urine protein, urea nitrogen, and creatinine.

However, in most cases, it is transient and will recover after the drug is reduced and stopped.

But your are recommended to insist on regular follow-up visits during the medication period and do blood routine and liver and kidney function checks.

2. Hypertension:

After taking it, some patients will experience increased blood pressure and may even induce hypertension.

Therefore, for elderly patients, it is necessary to pay close attention to this adverse reaction.

If you have symptoms of high blood pressure, you need to take the medication carefully and consult your doctor immediately.

3. Cell carcinogenesis:

Like other immunosuppressants, it will greatly increase the posibility of developing lymphoma or other malignant tumors, which means it may cause cancer.

During the period of taking the medication, patients need to avoid excessive exposure to ultraviolet light to avoid malignant skin lesions and incurable skin cancer.

4. Weight gain:

As one of immunosuppressive drugs, the patients may experience obesity after taking it.

This is mainly due to the fact that these drugs are prone to water and sodium retention, and the body has symptoms of central obesity, which can be manifested as a round face and slender limbs, but the abdominal muscles are greatly increased.

5. Other side effects:

Other side effects may include increased body hair, gingival hyperplasia, paresthesia, and sometimes gastrointestinal disorders.

In severe cases, it may also cause a series of concurrent diseases such as Raynaud’s syndrome, diabetes, and pancreatitis, and the number of white blood cells in the blood may also decrease.

To conclude: it is a common and safe chemical for shipment by air, while it will cause many unwanted side effects and it is better to take extra care when you are taking its medictions.

Cyclosporine vs Tacrolimus

cyclosporine vs tacrolimus

Those two are common drugs used for patients of transplantation to achieve adequate immunosuppression and to prevent acute rejection.

Below are their differences in details.

#1. Marketing period

Cyclosporine was discovered in 1971 and approved as immunosuppressant drugs for organ transplant rejection.

Tacrolimus was not discovered till 1980s and not approved as drug for transplant rejections untill 1989.

#2. Danger to Kidney

Studies conducted by Nephrology Department, Hospital de Santo António, Porto, Portugal has shown that tacrolimus is less nephrotoxic.

While tacrolimus showed easier blood pressure control but a higher chance to cause diabetes.

#3. Popularity

Studies have showed that tacrolimus is superior in terms of survival, graft loss, acute rejection, and steroid-resistant rejection in the first year.

Tacrolimus is the most popular for maintenance immunosuppression after liver transplantation.

#4. Raw material cost

For both those pharm-grade APIs approved by Chinese SFDA, the tacrolimus price is much higher.

The tacrolimus price of 100G is about 130usd/g, while the cyclosporine price is about 2500~3000usd/kg.

One is sold by GRAM, one is sold by KG. Tacrolimus is is just more expensive in terms of unit price.

What Is Cyclosporine's HS Code?

#1. As an API

For pure powder, it is an organic compound and a cyclic peptide with eleven amino acids.

Though it is used as an immunosuppressant, it is classified as one group of chemical compounds called other antibiotics with HS code as 2941909090 in China before Oct. 2020.

Later it was categorized for a while as other organic compounds with HS Code 2942000000. 

Speaking of 29420000, please pay close attention to the HS Code starting with 2942, it is very tricky and Chinese Customs are very strict and sensitive on it.

Once we declare our Propylthiouracil powder as 2942000000 (the correct hs code for propylthiouracil should be 2933599099.

Our goods are rejected from our customs for false HS declaration once.

Later we had to declare it again to get it released from Shanghai airport.

The latest correct HS Code for pure powder is 2933990099, categorized as Other heterocyclic compounds containing only nitrogen heteroatoms. (其他仅含氮杂原子的杂环化合物)

#2. When made into Finished Formulations

If you are importing its finished formulations, its HS code should be 3004909099, which means Other medicines in prescribed doses(其他已配定剂量的药品)

Atopica is not recommended for use in bred dogs unless a veterinarian considers the risk-benefit ratio that is justified by the veterinarian.

Cyclosporine, marketed under the brand name Atopica or Optimmune, is an immunosuppressant commonly used in dogs and cats to treat atopic dermatitis.
