（技術分野）
本発明は、血液凝固促進剤に関する。
（従来技術）
近年、検査技術の目覚しい進歩と相俟つて、血
清生化学検査、血清免疫学検査、血球検査等の血
液検査が広く普及し、病気予防や早期診断に大き

液検査の主体をなしており、この検査において必
要な血清は、通常、血液を血液検査用容器に採取

しかしながら、一般に血液は凝固するまでにか
なりの時間を要し、従来、迅速に検査を実施する
ことが困難である。最も血液凝固時間が短いとさ

注入した後、凝固に至るまでに40分乃至60分を必
要とし、合成樹脂製血液検査用容器に至つては、
血液凝固までに４時間以上の放置を必要とする。
このため、血液凝固第因子活性化能を有

能検査の一つである活性化部分トロンボプラスミ
ン時間の測定試薬の一成分として実用に供されて
いるが、その純度や組成等によつてその活性化能
が安定しない問題がある。
更に、これらの血液凝固促進剤による場合、一
般に血液凝固後に血清から血餅を遠心分離し、血
清を採取する際に血清の分離性がよくなく、血清
に血餅成分が混入するのを避けられない。
（発明の目的）
本発明は上記した問題を解決するためにされた
ものであつて、因子を活性化させ、血液凝固
に要する時間を大幅に短縮させると共に、その血
液凝固の促進効果が極めて安定しており、更に、
血清の分離性にもすぐれた血液凝固促進剤を提供
することを目的とするものである。
（発明の構成）
本発明の血液凝固促進剤は、血液凝固第因
子の非酵素的活性化剤と、アミノ酸配列において
Arg又はLys残基と任意のアミノ酸残基との間の
結合の加水分解酵素とを含有することを特徴とす

本発明による血液凝固促進剤における一成分で
ある非酵素的活性化剤としては、
一般式
（但し、Ａは環式化合物の残基を示す。）
で表わされ、且つ、上記二つの相隣るカルボニル
基が立体的に実質的に同一の平面上にある環式有
機化合物が用いられる。
上記環式有機化合物は、二つの相隣るカルボニ
ル基と残基Ａとが形成する同素環式又は異節環式
化合物のいずれであつてもよく、また、このよう
な環式化合物は単環式であつても、多環式化合物
であつてもよいが、少なくとも二つのカルボニル
炭素を含む環が６員環又は５員環である環式化合
物である。
特に、好ましい６員環式化合物は次式
（但し、R1，R2，R3及びR4は水素基、炭化水
素、極性置換基又は多環式化合物における残基を
示す。）
で表わされるｏ−キノン環を有する化合物であ

ものではないが、好ましくはアルキル基であり、
また、上記極性置換基も特に制限されるものでは
ないが、例えば、カルボキシル基、カルボン酸エ
ステル基、水酸基、アミノ基、メルカプト基等で
ある。従つて、ｏ−キノン環を有する化合物の好
ましい具体例として、例えば、ｏ−キノン、次の
一般式
（但し、R5はアルキル基を示す。）
で表わされる没食子酸アルキルエステル酸化物、
次式
でそれぞれ表わされるエラジン酸部分酸化物及び
完全酸化物、次式
で表わされる１，４−ジ（３，４−ジヒドロキシ
フエニル）２，３−ジメチルブタン部分酸化物及

また、二つのカルボニル炭素を含む環が５員環
である同素環式化合物の好ましい具体例として、
次式
で表わされる１，２，３−トリケトヒドロインデ
ンを挙げることができる。
更に、上記環式化合物として好ましく用いるこ
とができる異節環式化合物の一つは、次の一般式
（但し、R6は水素、炭化水素基又は多環式化合

で表わされる、ここに、上記炭化存水素基及び極
性置換基については前記と同じである。
このような化合物の好ましい具体例として、例
えば、次式で表わされるイサチンを挙げることが
できる。
これら一群の化合物は、いずれも分子内に立体
的に同一の乃至は近似的に同一の平面上に二つの
相隣るカルボニル基をもち、詳細な作用機序は不
明であるが、血液凝固因子に対して特異的な効果
を示す。一方、同じく分子内に相隣るカルボニル
基をもちながら、それらが同一平面上にないため
に血液凝固促進剤機能をもたない化合物として
は、例えば次式で表わされる１，２−ジケトシク
ロヘキサンがある。
この場合、二つの相隣るカルボニル基をつなぐ
脂環はかなりのフレキシビリテイーを有し、その
ためにこれらカルボニル基同士は立体反発によつ
て相互にゴーシユの位置にあり、同一平面上にな
い。そして、この化合物は血液凝固因子に対して
何ら特異的な効果を示さない。これらの事実はお
そらく立体的な特別な位置にある二つの相隣るカ
ルボニル基がタンパク質である血液凝固因子のあ
る特定の部位と立体構造的に特殊な関係をもつた
めであろうと推測される。
次に、本発明による血液凝固促進剤の他の成分
である加水分解酵素は、アミノ酸配列において
Arg又はLys残基と任意のアミノ酸残基との間の
結合の加水分解酵素であり、このような加水分解
酵素としては、特にプロテアーゼが好ましく用い

様酵素等のセリンプロテアーゼ、カテプシンＢ、
フイシン等のチオールプロテアーゼ、キニナーゼ
のような金属プロテアーゼ等を挙げることがで
きるが、セリンプロテアーゼが入手容易でもある
ので、使用するのに好適である。これらプロテア
ーゼは、単独でも血液凝固を活性化し得るが、本
発明に従つて、前記した非酵素的活性化剤、特
に、前記環式化合物からなる因子活性化剤と
併用することによつて、血液凝固の活性化能が飛
躍的に向上するのである。
本発明の血液凝固促進剤の使用においては、例
えば、血液を血液検査用容器に採取し、これを凝
固させる際に促進剤を血液中に存在させる。この
場合、上記血液凝固促進剤は、これをそのままの
粉末状で血液中に存在させてもよいが、好ましく
は、血液凝固促進剤を適宜の溶剤に溶解若しくは
分散させて、血液中に添加する。上記血液検査用
容器は特に制限されず、従来より通常に用いられ
ているガラス製又は樹脂製の容器が適宜に用いら
れる。
尚、血液が血液検査用容器内において瞬間的
に、又は部分的に高濃度のこれら血液凝固促進剤
と接触し、血液中のタンパク質成分が変質するお
それがあるときは、比表面積の大きい担体に血液
凝固促進剤を担持させ、これを血液検査用容器中
の血液に添加してもよい。上記担体としては、血
液検査に有害な影響を与えず、大きい比表面積を
有するものであれば、特に制限されることなく、
種々のものを用いることができるが、例えば、不
織布、織布、樹脂ビーズ等を好適に用いることが
できる。このような担体に血液凝固促進剤を担持

し、又はこれに浸漬した後、乾燥して、担体に付
着させればよい。また、アラビアゴム等の適宜の
助剤と混合して水分散液とし、これを急速凍結乾
燥する等の方法により、血液凝固促進剤を担持し
た粒子状物を得ることもできる。
血液凝固促進剤の血液中における存在量は、血
液１mlについて少なくとも１×10-10ｇであり、
これよりも少ないときは、血液凝固の促進効果が
乏しい。しかし、余り多量に存在させるときは、
却つて血液検査に種々の支障を来すおそれがある
ので、10-1ｇ以下とするのが好ましい。
（発明の効果）
本発明の血液凝固促進剤によれば、これを血液
中に存在させるとき、因子が迅速に活性化さ
れ、容器に血液を採取後の凝固に要する時間が著
しく短縮されると共に、血餅成分の収縮が十分に

(Technical Field) The present invention relates to a blood coagulation promoter. (Prior art) In recent years, with the remarkable progress in testing technology, blood tests such as serum biochemistry tests, serum immunology tests, and hematology tests have become widespread, and have greatly contributed to disease prevention and early diagnosis. . Among these, serum tests are the main body of blood tests, and the serum required for this test is usually obtained by collecting blood into a blood test container, coagulating it, and then centrifuging it to collect blood with different specific gravities. The mochi, that is, a gel-like mass containing a mixture of fibrin and blood cells, is separated, and the serum portion is collected by pipetting or decanting. However, blood generally takes a considerable amount of time to coagulate, making it difficult to conduct tests quickly. Even with glass blood test containers, which are said to have the shortest blood coagulation time, it takes 40 to 60 minutes for blood to coagulate after blood is injected, and synthetic resin blood test containers do not. ,
It takes 4 hours or more for blood to coagulate. For this reason, glass, kaolin, bentonite, silica, ellagic acid, etc., which have the ability to activate blood coagulation factor and promote blood coagulation, are used as blood coagulation promoters in serum tests, as well as in blood coagulation function tests. Although it has been put to practical use as a component of a reagent for measuring the activated partial thromboplasmin time, there is a problem that its activation ability is unstable depending on its purity, composition, etc. Furthermore, when these blood coagulation promoters are used, blood clots are generally centrifuged from serum after blood coagulation, and serum separation is not good when serum is collected, making it difficult to avoid contamination of blood clot components with serum. do not have. (Objective of the Invention) The present invention has been made to solve the above-mentioned problems, and it activates factors, significantly shortens the time required for blood coagulation, and has an extremely stable blood coagulation promoting effect. In addition,
The object of the present invention is to provide a blood coagulation promoter that also has excellent serum separation properties. (Structure of the Invention) The blood coagulation promoter of the present invention comprises a non-enzymatic activator of blood coagulation factor and an amino acid sequence of
It is characterized by containing an enzyme that hydrolyzes the bond between Arg or Lys residue and any amino acid residue. The non-enzymatic activator, which is one component of the blood coagulation promoter according to the present invention, has the general formula (However, A represents a residue of a cyclic compound.) A cyclic organic compound is used in which the above two adjacent carbonyl groups are sterically located on substantially the same plane. . The above-mentioned cyclic organic compound may be either a homocyclic or a heterocyclic compound formed by two adjacent carbonyl groups and the residue A, and such a cyclic compound may be a monocyclic compound. Although it may be a cyclic or polycyclic compound, it is a cyclic compound in which the ring containing at least two carbonyl carbons is a 6-membered ring or a 5-membered ring. Particularly preferred six-membered cyclic compounds are of the following formula: (However, R 1 , R 2 , R 3 and R 4 represent a hydrogen group, a hydrocarbon, a polar substituent, or a residue in a polycyclic compound.) It is a compound having an o-quinone ring represented by: In the above formula, the hydrocarbon group is not particularly limited, but is preferably an alkyl group,
Furthermore, the polar substituents mentioned above are not particularly limited, but include, for example, a carboxyl group, a carboxylic acid ester group, a hydroxyl group, an amino group, a mercapto group, and the like. Therefore, as a preferable specific example of a compound having an o-quinone ring, for example, o-quinone, the compound having the following general formula (However, R 5 represents an alkyl group.) Gallic acid alkyl ester oxide represented by
The following formula ellagic acid partial oxide and complete oxide, respectively represented by the following formula: Examples include 1,4-di(3,4-dihydroxyphenyl)2,3-dimethylbutane partial oxide and complete oxide represented by: Further, as a preferable specific example of a homocyclic compound in which the ring containing two carbonyl carbons is a 5-membered ring,
The following formula 1,2,3-triketohydroindene represented by: Furthermore, one of the heterocyclic compounds that can be preferably used as the above-mentioned cyclic compound has the following general formula: (However, R 6 represents hydrogen, a hydrocarbon group, or a residue in a polycyclic compound, and R 7 and R 8 represent hydrogen, a hydrocarbon group, a polar substituent, or a residue in a polycyclic compound.) Here, the hydrocarbon-existing hydrogen group and polar substituent are the same as described above. A preferred specific example of such a compound is isatin represented by the following formula. All of these group of compounds have two adjacent carbonyl groups on the same or approximately the same steric plane within the molecule, and although the detailed mechanism of action is unknown, blood coagulation factors It shows a specific effect on. On the other hand, examples of compounds that have carbonyl groups adjacent to each other in the molecule but do not have a blood coagulation promoter function because they are not on the same plane include 1,2-diketocyclohexane represented by the following formula. There is. In this case, the alicyclic ring connecting two adjacent carbonyl groups has considerable flexibility, and therefore these carbonyl groups are in mutually gauche positions due to steric repulsion and are not on the same plane. This compound does not exhibit any specific effect on blood coagulation factors. It is speculated that these facts are probably due to the fact that two adjacent carbonyl groups in special steric positions have a special steric structure with a specific site of a blood coagulation factor, which is a protein. Next, the hydrolase, which is another component of the blood coagulation promoter according to the present invention, has an amino acid sequence of
It is an enzyme that hydrolyzes the bond between an Arg or Lys residue and any amino acid residue, and protease is particularly preferably used as such a hydrolase. Specific examples of this protease include trypsin, thrombin, serine proteases such as snake venom thrombin-like enzymes, cathepsin B,
Examples include thiol proteases such as fuicin and metalloproteases such as kininase, but serine proteases are easily available and are therefore suitable for use. Although these proteases can activate blood coagulation alone, according to the present invention, they can activate blood coagulation by using them in combination with the above-mentioned non-enzymatic activator, especially the factor activator consisting of the cyclic compound. The ability to activate coagulation is dramatically improved. In using the blood coagulation promoter of the present invention, for example, blood is collected into a blood test container and the promoter is present in the blood when coagulating the blood. In this case, the blood coagulation promoter may be present in the blood as it is in powder form, but preferably, the blood coagulation promoter is dissolved or dispersed in an appropriate solvent and then added to the blood. . The blood test container is not particularly limited, and conventional glass or resin containers may be used as appropriate. In addition, if blood comes into contact with these blood coagulation promoters momentarily or partially in a blood test container and there is a risk that protein components in the blood may be denatured, use a carrier with a large specific surface area. A blood coagulation promoter may be supported and added to the blood in the blood test container. The carrier is not particularly limited as long as it does not have a harmful effect on blood tests and has a large specific surface area.
Although various materials can be used, for example, nonwoven fabrics, woven fabrics, resin beads, etc. can be suitably used. In order to support a blood coagulation promoter on such a carrier, for example, the carrier may be coated with a solution or dispersion thereof, or immersed therein, and then dried and attached to the carrier. Further, particulate matter carrying a blood coagulation promoter can also be obtained by mixing with an appropriate auxiliary agent such as gum arabic to form an aqueous dispersion, and then rapidly freeze-drying the resulting aqueous dispersion. The amount of the blood coagulation promoter present in the blood is at least 1 x 10 -10 g per ml of blood;
When the amount is less than this, the effect of promoting blood coagulation is poor. However, when present in too large a quantity,
On the contrary, it may cause various problems in blood tests, so it is preferable to limit the amount to 10 -1 g or less. (Effects of the Invention) According to the blood coagulation promoter of the present invention, when it is present in blood, factors are rapidly activated, and the time required for coagulation after blood is collected into a container is significantly shortened. As a result of sufficient contraction of blood clot components, the separability of serum and blood clot is excellent, and the blood clot components are not mixed into the separated and collected serum, and furthermore, the yield of serum is significantly increased. Therefore, the blood coagulation promoter of the present invention can be widely used in the field of clinical testing, and can also be used for hemostasis of bleeding wounds. The present invention will be explained below with reference to Examples, but the present invention is not limited to these Examples in any way. (Example) Example 1 Ellagic acid oxide and 1,2,3-triketohydroindene were used as the cyclic compound as a blood coagulation factor activator, and trypsin, thrombin and snake venom thrombin-like were used as proteases. A blood coagulation promoter aqueous solution according to the present invention was prepared using each enzyme. The content of each component in each blood coagulation promoter is 0.5% by weight for the cyclic compound, and 0.5% by weight for the protease, trypsin, thrombin, and snake venom thrombin-like enzyme.
0.05% by weight, 500 units/ml and 0.005% by weight. Using a commercially available polyethylene plain spit, 30μ of the blood coagulation promoter according to the present invention was added to 3ml of fresh human blood, and the time required for the blood to lose its fluidity was measured as the coagulation time. ,
The mixture was centrifuged at 3000 rpm for 5 minutes and the state of separation was observed. The results are shown in Table 1. Comparative Example 1 For comparison, Table 2 shows the clotting time and separation state when the cyclic compound and protease used in Example 1 were used alone. Comparative Example 2 Table 3 shows the clotting time and separation state when blood was treated in the same manner as in Example 1, except that no blood coagulation promoter was used.
