Description

A kind of preparation method of people's Antithrombin III
Technical field
The invention belongs to field of biological pharmacy, relate to a kind of preparation method of blood product, be specifically related to a kind of preparation method of people's Antithrombin III.
Background technology
Antithrombin Ⅲ (antithrombin III; AT-III) be the single chain glycoprotein that a kind of vitamin K relies on; synthesize in liver, vascular endothelial cell and megalokaryocyte; it is the inhibitor containing the proteolytic enzyme of Serine such as zymoplasm and the factor Ⅻ α, Ⅺ α, Ⅸ α, Ⅹ α; molecular mass is 58-64KD, and iso-electric point is 4.8; About 70 hours transformation period, content 260-320mg/L in blood plasma; Containing 4 N glycosylation oligonucleotide chains and 3 disulfide linkage, by 9 α-helixstructures, 3 beta sheets and 1 reactive center ring composition; The Serines such as AT-III and zymoplasm, FXa, FXIIa, XIa, IXa, plasmin form mixture with the ratio of l:l, thus these enzymes are lost activity, heparin can accelerate this reaction and reach more than thousand times, AT-III conformational change is caused after heparin and the Lysine binding contained by AT-III, arginine residues contained by AT-III is more easily combined with the serine residue of zymoplasm, once heparin-AT-III antithrombin complex is formed, heparin just dissociates from mixture, is again combined with another molecule AT-III and is recycled.
AT-III is the anticoagulant main component of composition, account for 75% of the total anticoagulation ability of human body, it is the key substance of Trombin inhibiting in blood plasma, as the most important obstruction factor of factor Xa in blood, which control solidifying and fibrinous dissolving of blood, participate in the running balance of anticoagulant functions and fibrinolytic system and blood coagulation system in holder, and play anti-freezing regulating effect.Clinically, in blood the level of AT-III with various disease, symptom and changing, in reductions such as disseminated inravascular coagulation (DIC), liver illness, nephrotic syndromes.AT-III level reduction in blood may cause heparin therapy effect to present.Therefore, the activity grasping AT-III is as the monitoring of this type of disease, ill-condition analysis, prognosis judgement and heparin therapy or use the index during dispensing of AT-III concentrate formulation significant.
In recent years find that AT-III urgees endothelial cells secrete prostacyclin, suppresses leukocyte surface chemoattractant receptor syndecan-4, amelioration of inflammation reacts.Measure AT-III content in blood plasma and can judge the thrombotic cause of disease, can directly also can form mixture with zymoplasm and suppress multiple coagulation factor activity by Trombin inhibiting.In addition, AT-III pair of platelet aggregation also has certain restraining effect, is main intrinsic coagulation inhibition.As clinical application, it treatment congenital and day after tomorrow acquired AT-III lack in deficiency disease, there is the effect being difficult to substitute.It is a kind of autosomal dominant disease that heredity AT-III lacks, this sick morbidity about 1/5000, morbidity many 10-25 year, patient is everlasting after Post operation, wound, infect after, gestation or phlebothrombosis occurs postpartum, and repeatedly can there is thrombus.In patients blood plasma, to be about the type of normal people about 50%, AT-III structure and fuction exception more for AT-III biological activity and antigenicity, and coexpress reduces the avidity of heparin, thus obviously weaken the inactivation capacity of serine protease.Acquired AT-III shortage shows as AT-III and synthesizes reduction, and see hepatic diseases, hepatic insufficiency, be mainly seen in liver cirrhosis, hepatitis gravis, later period of hepatocarcinoma, normal relevant to Disease severity, can occur together thrombosis.
Namely the research preparing AT-III from blood of human body has been carried out in the world from the sixties in last century, along with deepening continuously to AT-III structure and Study on mechanism, preparation method also reaches its maturity, AT-III goods have been widely used in clinical in the world, and have developed recombinant human AT-III product.The domestic research to AT-III is few, there is no AT-III product at present and emerges, lack the various diseases caused, lack remedy measures targetedly for because of AT-III; In recent years fragmentary research report is had to occur, as patent CN103059129A.Conventional preparation technology, yield is lower, and owing to lacking the removal measure of the thrombin that vitamin k relies on, easily causes protein activation, cause AT-III production qualification rate not high in preparation process.
Given this, this invention exploits a kind of novel method preparing AT-III lyophilized powder, there is process stabilizing, qualification rate is high, lyophilized powder redissolution liquid clear, without the advantage separated out without opalescence, and through S/D, nano-film filtration, xeothermic three step inactivation of virus, substantially increase the security that product uses.
