Description
Technical field
The present invention relates to biomedicine technical fields, and in particular to a kind of separation purifying technique of cyclosporin A.
Background technology
Cyclosporin A (Ciclosporin A, CsA) is from porous trichoderma (Tolypocladium inflatum
CSP3), one kind isolated in the culture of just entitled Beauveria nivea (Beauveria bassiana) contains 11 ammonia after
The ring type polypeptide of base acid is a kind of very strong immunosuppressor of effect, also has more than 20 kinds of B, C, D etc. other than cyclosporin A together
It is object.For the immunosuppressive therapy of the transfer operations such as kidney, liver and heart, it can also be used to treat ciclosporin A
Autoimmune disease, such as lupus erythematosus, rheumatoid arthritis, Idiopathic Thrombocytopenic Purpura, ulcerative colitis, again
The various autoimmunes disease such as disease myasthenia, chronic nephritis, chronic active hepatitis and nephrotic syndrome.
Major impurity in cyclosporin A fermented product is the similar cyclosporin A homologue of structure, including B, C, D etc.,
It is in the prior art first to be extracted with organic solvent for the extraction purification dominating process route of cyclosporin A, then passes through difference
The column chromatography of type is isolated and purified.
CN200510108097.9 describes one kind and obtains cyclosporin coarse crystal first, recycles column chromatographic isolation and purification
Cyclosporin A, and the purifying process of secondary crystallization is carried out, this method coarse crystallization complex process is more using organic solvent type, has
A little solvents are expensive, and crystallize needs 3 days, and time-consuming for entire purifying process.US5656459 discloses a kind of extraction purification
Technique is first extracted with methanol, and extract is dissolved in ethyl acetate by removal methanol again, and ring spore bacterium is obtained by silica gel column chromatography twice
Plain A sterlings, technique extraction cannot be connected with silica gel column chromatography solvent for use, need to convert, and silica gel column chromatography is often, total to receive
Rate is low.
US5382655 is disclosed a kind of isolates and purifies cyclosporin A by the use of chloroform, dichloromethane and ethyl alcohol as mobile phase
Silica gel column chromatography method, but these solvent toxicities are big, it is unfriendly to environment.Patent US597638 discloses a kind of utilization high pressure two
The method that carbonoxide obtains cyclosporin A as flowing carrier by silica gel column chromatography, but this method is to equipment requirement height, sample
Treating capacity is few, can not realize extensive large-scale production.Patent US2002/0162789A1 discloses a kind of multistep silica gel color
Spectrum separation, mobile phase toluene and ethyl acetate, major defect are that toluene toxicity is big, and chromatographic step is more, and solvent consumption is big.WO01/
64935A1 describe it is a kind of extracted using organic solvent, the side of gel filtration and silica gel column chromatography separating purification cyclosporin A
Method, this method major defect are that gel filtration filler is expensive, and all need to remove the solvent of back between each step,
Heavy workload, solvent consumption are more.US2003/0186856A1 isolates and purifies ring spore bacterium using sephadex by twice chromatographic
The method of plain A, main problem is filler price, of high cost.CA2108655 provides a kind of using superfluid abstraction technique point
Method from cyclosporin A, this method investment is big, of high cost, is not suitable for industrialized production.
Comprehensive disclosure patent is mainly characterized by first being extracted with organic solvent, then utilizes one or multi-step silicagel column
Chromatography is isolated and purified, some separation purifying techniques are of high cost, are not suitable for industrialized production, some process solvent toxicity
Greatly, consumption is big, and total recovery about 40%~60%.
《Chinese antibiotic magazine》Article (number:1001-8689 (2008) 05-0276-04) report is using macroporous absorption
Resin HP combinations high speed adverse current chromatogram detaches cyclosporin small component, can realize that enrichment detaches, but the party again to cyclosporin
Method treatment scale is small, equipment requirement is high, is unfavorable for industrialized production.
Invention content
The purpose of the present invention is to provide a kind of extensive, efficiently industrialization purification high purity cyclosporin A new methods.
It is isolated and purified for cyclosporin A in the prior art in the prevalence of complex process, complex steps, organic solvent kind
The shortcomings such as class is more and dosage is big, and pigment poor removal effect and total recovery are low, inventor to cyclosporin A separation purifying technique into
The a large amount of research of row, for the biochemical property of ciclosporin A, gropes experiment condition and technological parameter, using macroporous absorption and
The separation method that PS30RPC type polymer nano-microspheres column chromatographies are combined, achieves good technique effect, and the present invention uses
Macroporous adsorption resin chromatography technology, organic solvent in extracting solution without displacement can direct loading macroporous absorbent resin, elute
Agent dosage is few, experimentally determined only to need 1.5~2 times of column volumes that elute cyclosporin A completely, and cyclosporin A is played
The enrichment method effect of highly significant, and most pigments can be removed, it solves the disadvantage that original extraction process, improves
Product yield;Since macroporous adsorption resin chromatography has been removed most of impurity, the present invention is in PS30RPC type polymer nanocomposites
Using Non-gradient elution in microballoon column chromatography, and the organic solvent-acetone and water that use toxicity low be as mobile phase, compared to ladder
Degree elution, simplifies chromatography technique, reduces environmental pollution.
The invention is realized by the following technical scheme:
(1) extraction of cyclosporin A
Into zymotic fluid plus NaOH tune PH is to neutrality, adds in organic solvent, stirring extraction 5~8 hours, by extracting solution press filtration
Go out thalline, collect filtrate.

80mL/min detects efflux with HPLC, collects qualified products.
(4) crystallization purifying
Eluent is concentrated in vacuo and crystallizes, and is washed with acetone petroleum ether or hexane acetone, is finally dried in vacuo colourless
Powdered cyclosporin A sterling.
Eluent is concentrated under reduced pressure into acetone under the conditions of 40 DEG C~60 DEG C and is all removed with ethyl acetate, adds in 1:1 second
Acetoacetic ester is extracted, and the ethyl acetate containing ciclosporin A is carried out again to be concentrated into 2L, Powdered Activated Carbon 25g is added in, adds anhydrous
Sodium sulphate 50g is stirred decoloration and dry 1h, decoloration is filtered with the dried ethyl acetate containing ciclosporin A, mistake
Ethyl acetate item after filter carries out being concentrated under reduced pressure into yellow lotion again, adds in a small amount of acetone solution, slowly drips under stiring
Add petroleum ether solution, crystallized under the conditions of being placed in -5 DEG C~-20 DEG C, preferably -10 DEG C, crystal is collected by filtration, with cold acetone petroleum ether
Washing is dried under the conditions of 40 DEG C~60 DEG C to constant weight.
The technical effects of the invention are that:By using macroporous adsorption resin chromatography adsorbing separation cyclosporin A, relative to
Traditional extraction technique can make consumption of organic solvent reduce 1-2 times, and pigment removal reaches 95%, and the concentration of cyclosporin A is through dense
Contracting enrichment can improve nearly 10 times, and bulky extractor can be saved from slave device requirement, reduce energy consumption and labour is strong
Degree;PS30RPC type polymer nano-microspheres column chromatographies column chromatography is using the acetone that toxicity is low, price is relatively cheap, ethyl acetate
With water as mobile phase, using Isocratic clution relative to gradient elution, reduce processing step, improve yield (75% with
On) and purity (more than 98% HPLC), in terms of entire process route, without complicated intermediate steps solvent replacement process, technique
It is simple to operation, PS30RPC type polymer nano-microspheres fillers through regeneration can Reusability, suitable for industrialized production.
