用途
ε-アミノカプロン酸（イプシロンあみのかぷろんさん）は人工合成されたアミノ酸で、止血剤として用いられる。
ε-アミノカプロン酸はここでフィブリンに拮抗してプラスミノーゲンに結合して活性化を阻害し、これによってフィブリンの分解による出血を抑制する。
内服または注射で用いられる。手術後の出血を抑えるのに用いられ、例えば血友病患者の抜歯後に使われる。また冠状動脈バイパス手術後の出血を有意に減らすことが明らかにされている。
歯茎の出血?炎症を抑えるとして、歯磨などにも入れられている。

製造方法
6-aminocaproic acid is obtained by hydrolysis of 6-(N-benzoylamino)capronitrile in the presence of hydrochloric acid, or by hydrolysis of caprolactam in the presence of hydrochloric acid, and then treated with ammonium hydroxide.

主な応用
6-Aminohexanoic acid was used as a biochemical reagent. It is also used as a hemostatic agent. 6-aminocaproic acid has a significant effect on some severe bleeding caused by increased fibrinolytic activity. It is suitable for oozing or local bleeding during various surgical operations. 6-aminocaproic acid is used for hemoptysis, gastrointestinal bleeding and bleeding disorders in obstetrics and gynecology.
6-Aminocaproic acid is an anti-fibrinolytic drug with a similar chemical structure to lysine. It can qualitatively inhibit the binding of plasminogen to fibrin and prevent its activation, thereby inhibiting fibrinolysis and achieving hemostasis. Aminocaproic acid is a monoaminocarboxylic acid, which can inhibit the conversion of plasminogen into plasmin and its binding to fibrin. For severe bleeding caused by hyperfibrinolysis caused by increased activation of plasminogen, can have therapeutic effect.

定義
ChEBI: 6-aminohexanoic acid is an epsilon-amino acid comprising hexanoic acid carrying an amino substituent at position C-6. Used to control postoperative bleeding, and to treat overdose effects of the thrombolytic agents streptokinase and tissue plasminogen activator. It has a role as an antifibrinolytic drug, a hematologic agent and a metabolite. It is an epsilon-amino acid and an omega-amino fatty acid. It derives from a hexanoic acid. It is a conjugate acid of a 6-aminohexanoate. It is a tautomer of a 6-aminohexanoic acid zwitterion.

一般的な説明
6-Aminocaproic acid is a synthetic inhibitor of fibrinolysis and is utilized for the control of excessive bleeding in patients with amegakaryocytic thrombocytopenia. It also is a protease inhibitor that displays anticancer activity but is limited by cytotoxicity.

作用機序
Because binding of plasminogen or plasmin to fibrinogen or fibrin is mediated by lysine
groups that are part of the structures of fibrin and fibrinogen, aminocaproic acid, which is
a structural analog of lysine that only differs in that it has one less amino group, acts as a
competitive inhibitor for binding of plasmin(ogen) to fibrin. Aminocaproic acid shifts the
homeostatic balance on the side of coagulation, thus restoring fibrinolytic mechanism
activity. Aminocaproic acid, which is not a procoagulant, such as those used during surgical
intervention and various pathological conditions, is accompanied by an elevation in fibrinolytic
activity of blood and tissue. It is used to stop bleeding.
