Description

white crystalline powder


Solid


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.|An antifibrinolytic agent that acts by inhibiting plasminogen activators which have fibrinolytic properties.|Aminocaproic acid is an Antifibrinolytic Agent. The physiologic effect of aminocaproic acid is by means of Decreased Fibrinolysis.|Aminocaproic Acid is a synthetic lysine derivative with antifibrinolytic activity. Aminocaproic acid competitively inhibits activation of plasminogen, thereby reducing conversion of plasminogen to plasmin (fibrinolysin), an enzyme that degrades fibrin clots as well as fibrinogen and other plasma proteins including the procoagulant factors V and VIII. Aminocaproic acid competitively reduces the conversion of plasminogen to plasmin by plasminogen activators. It directly inhibits proteolytic activity of plasmin, but higher doses are required than are needed to reduce plasmin formation. Aminocaproic acid is used in the treatment of hemorrhage and prophylactically against hemorrhage, including hyperfibrinolysis-induced hemorrhage and postsurgical hemorrhage.

Toxicity

practically nontoxic

A few cases of acute overdosage with intravenous administration have been reported. The effects have ranged from no reaction to transient hypotension to severe acute renal failure leading to death. The intravenous and oral LD50 were 3.0 and 12.0 g/kg respectively in the mouse and 3.2 and 16.4 g/kg respectively in the rat. An intravenous infusion dose of 2.3 g/kg was lethal in the dog.

Aminocaproic acid works as an antifibrinolytic. It is a derivative of the amino acid lysine. The fibrinolysis-inhibitory effects of aminocaproic acid appear to be exerted principally via inhibition of plasminogen activators and to a lesser degree through antiplasmin activity. Aminocaproic acid may be a possible prophylactic for vascular disease, as it may prevent formation of lipoprotein (a), a risk factor for vascular disease.

Agents that prevent fibrinolysis or lysis of a blood clot or thrombus. Several endogenous antiplasmins are known. The drugs are used to control massive hemorrhage and in other coagulation disorders. (See all compounds classified as Antifibrinolytic Agents.)

Absorbed rapidly following oral administration. In adults, oral absorption appears to be a zero-order process with an absorption rate of 5.2 g/hr. The mean lag time in absorption is 10 minutes. After a single oral dose of 5 g, absorption was complete (F=1).|Renal excretion is the primary route of elimination, whether aminocaproic acid is administered orally or intravenously.|23.1 ± 6.6 L|169 mL/min|AMINOCAPROIC ACID IS WELL ABSORBED ORALLY...

Sixty-five percent of the dose is recovered in the urine as unchanged drug and 11% of the dose appears as the metabolite adipic acid.

The terminal elimination half-life is approximately 2 hours.

Aminocaproic acid binds reversibly to the kringle domain of plasminogen and blocks the binding of plasminogen to fibrin and its activation to plasmin. With NO activation of plasmin, there is a reduction in fibrinolysis. This consequently will reduce the amount of bleeding post surgery. Elevated plasma levels of lipoprotein(a) have been shown to increase the risk of vascular disease. Lipoprotein 9a)a has two components, apolipoprotein B-100, linked to apolipoprotein (a). Aminocaproic acid may change the conformation of apoliprotein (a), changing its binding properties and potentially preventing the formation of lipoprotein (a).|A COMPETITIVE INHIBITOR OF ACTIVATORS OF PROFIBRINOLYSIN &, TO LESSER EXTENT, OF FIBRINOLYSIN.

6 Aminocaproic Acid

6-Aminohexanoic acid Use and Manufacturing

Methods of Manufacturing

Derived from the hydrolysis of caprolactam. Caprolactam, concentrated hydrochloric acid and 3 times the amount of distilled water were added to the reaction tank, stirred, heated to reflux for 1.5h, and controlled the temperature of 103-106 ℃. After the reaction, the conversion rate should be above 95%. Diluted with distilled water to 10% concentration to obtain 10% 6-aminocaproic acid hydrolysate. The hydrolysate was evenly flowed into an ion exchange column [packed with 001×7 (732#) strong acid styrene cation exchange resin] at a flow rate of 5-10 L per hour for adsorption. After the flow is complete, close the outlet and soak overnight. Wash the ion exchange column with distilled water to remove hydrochloric acid (check the effluent to be free of chloride ions). Then, uniformly flow 3.5% ammonium hydroxide at a flow rate of 5-10 L per hour. After the flow is completed, the flow outlet is closed and soaked overnight. After the completion of ammonium hydroxide the next day, it was poured into distilled water for elution, and the eluent containing 6-aminocaproic acid was collected. Activated carbon was added for decolorization and filtration. The filtrate was concentrated at 47-70°C under reduced pressure and nearly dried. Ethanol was added while hot, and crystals were precipitated by stirring. After cooling, shake and filter to get crude product. Dissolve the crude product in distilled water and add activated carbon to decolorize at 60℃ for 1h. Filter while hot. The filtrate was concentrated under reduced pressure and nearly dried. Ethanol is added to precipitate crystals, which are cooled, spin-filtered, and the crystals are washed with ethanol and dried to obtain 6-aminocaproic acid. The total yield of caprolactam is 75-80%.

Uses

EACA is directly soluble in water at 25 mg/ml. As an inhibitor of plasmin it is has been utilized in the clotting buffer for fibrinogen assays. This buffer is 10 mM potassium and sodium phosphate, pH 6.4, with 0.20 g CaCl2, 5 g 6-Aminohexanoic acid, 1 g sodium azide, and 9 g NaCl in 1 liter. The buffer is stable indefinitely at room temperature.
