6-Aminohexanoic Acid (ε-​Aminocaproic Acid; 6-Aminocaproic Acid) (CAS: 60-32-2) (Brand name: Amicar) is a kind of synthetic derivative of lysine. Since it is a analogue of amino acid lysine, it can act as the inhibitor for enzymes that need to bind to that particular lysine residue, e.g. the proteolytic enzyme such as plasmin, which is responsible for fibrinolysis. Therefore, It has anti-fibrinolytic activity. It also competitively inhibits activation of plasminogen, thereby reducing conversion of plasminogen to plasmin. Based on this property, it can be used for the treatment of acute bleeding due to elevated fibrinolytic activity in many clinical situations. It can also indicated by FDA for the prevention of recurrent hemorrhage in patients of traumatic hyphema. It may also act as a prophylactic against the vascular disease due to its inhibitory effect on the formation of lipoprotein which is the risk factor of vascular disease. Aminobenzoic Acid Gel, Aminocaproic Acid Injection, Aminocaproic Acid Oral Solution, Aminobenzoic Acid Topical Solution.
6-Aminohexanoic Acid was used as a biochemical reagent. 6-Aminocaproic Acid is used in organic synthesis. As an anti-fibrinolytic agent. 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 also used for hemoptysis, gastrointestinal bleeding and bleeding disorders in obstetrics and gynecology. 6-Aminocaproic Acid works by inhibiting the fibrinolytic system. Mainly used for hemorrhage caused by elevated plasmin activity, such as obstetrics and gynecology hemorrhage, hemorrhage after prostate, liver, pancreas, lung and other visceral operations. Early intraoperative medication or preoperative medication can reduce intraoperative oozing and reduce blood transfusion volume.
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.
