| Eptifibatide Usage And Synthesis |
| Description | Eptifibatide is a kind of synthetic cyclic hexapeptide consisting of 6 amino acids and 1 mercaptopropionyl residue. It is capable of binding to the platelet receptor glycoprotein (GP) IIb/IIIa of human platelets and inhibiting the platelet aggregation, thus blocking the binding of the fibrinogen, von Willebrand factor and other adhesive ligands. It is indicated for the treatment of acute coronary syndrome (ACS) and Percutaneous coronary intervention (PCI). It is able to reduce the risk of acute cardiac ischemic events in patients with unstable angina or non-ST segment-elevation myocardial infection. It is often used in combination with aspirin or clopidogrel and heparin. It can be manufactured through solution-phase peptide synthesis, and can be purified by preparative reverse-phase liquid chromatography and lyophilization.

| | Description | Eptifibatide is a reversible antagonist of the glycoprotein llb/llla complex, a specific platelet adhesion receptor that plays a central role in the cascade of thrombus formation by allowing mediators such as fibrinogen or von Willbrand factor to cross-link adjacent platelets and to give rise to aggregation. In diverse animal experimental models of arterial thrombosis, treatment with Eptifibatide resulted in an enhanced lysis of occlusive thrombus and a restoration of arterial blood flow. In clinical trials involving patients with acute coronary syndromes, Eptifibatide demonstrated a significant decrease in the incidence of death or nonfatal myocardial infarction at 30 days. In other trials in patients undergoing percutaneous coronary intervention (PCI), it showed a positive trend. Eptifibatide has the advantage of being short acting, its antiplatelet effect being rapidly reversible. | | Originator | Cor Therapeutics (US) | | Uses | Eptifibatide is a cyclical heptapeptide with anticoagulant activity. Eptifibatide selectively and reversibly binds to and blocks the platelet glycoprotein IIb/IIIa receptor. This prevents the binding of fibrinogen, von Willebrand factor, and other adhesive ligands and leads to an inhibition of platelet aggregation and prevents thrombus development. It is an efficient peptide drug to reduce the risk of cardiac ischemic events, however has a short half-life. Therefore, antithrombotic agents like eptifibatide are required to become improved with a protected and targeted delivery system such as using nano-liposomes to the site of thrombus. | | Definition | ChEBI: Eptifibatide is a synthetic homodetic cyclic peptide comprising N(alpha)-(3-sulfanylpropanoyl)homoarginyl, glycyl, aspartyl, tryptophyl, prolyl and cysteinamide residues connected in sequence and cyclised via a disulfide bond. Derived from a protein found in the venom of the southeastern pygmy rattlesnake, Sistrurus miliarus barbouri, eptifibatide is an anti-coagulant that inhibits platelet aggregation by selectively blocking the platelet glycoprotein IIb/IIIa receptor, so preventing the binding of fibrinogen, von Willebrand factor, and other adhesive ligands. It is used in the management of unstable angina and in patients undergoing coronary angioplasty and stenting procedures. It has a role as a platelet aggregation inhibitor and an anticoagulant. It is an organic disulfide, a macrocycle and a homodetic cyclic peptide. | | Brand name | Integrilin | | General Description | Eptifibatide (Integrilin) is a syntheticcyclic heptapeptide that acts as a GPIIb/IIIa receptor antagonist,thus causing inhibition of platelet aggregation. Itsstructure is based on the natural product barbourin, a peptideisolated from the venom of a pygmy rattlesnake (Sistrurusmilarud barbouri). As part of the structure, there is a sequenceRGD that can bind to the RGD receptor found onplatelets and block its ability to bind with fibrinogen. Thisagent is used in the treatment of unstable angina and for angioplasticcoronary interventions. | | Biological Activity | Eptifibatide is a potent glycoprotein IIb/IIIa antagonist (GPIIb/IIIa; Kd = 120 nM) that inhibits platelet aggregation. Eptifibatide prevents binding of the adhesion proteins fibrinogen and von Willebrand factor to GPIIb/IIIa on the surface of activated platelets to prevent aggregation and thrombus formation. It inhibits ADP-induced citrated blood aggregation (IC50 = 0.11-0.22 μg/ml) in vitro and in vivo (IC50 = 52 μg/ml in porcine plasma). Formulations containing eptifibatide have been used to reduce risk of thrombolysis in myocardial infarction in patients undergoing percutaneous coronary intervention. | | Mechanism of action | Eptifibatide, a synthetic cyclic heptapeptide containing six amino acids, including one cysteine amide and one mercaptopropionyl (desamino cysteinyl) residue, is an inhibitor of platelet aggregation and belongs to the class of RGD (arginine-glycine-aspartate)-mimetics.Eptifibatide reversibly inhibits platelet aggregation by preventing the binding of fibrinogen, von Willebrand factor and other adhesive ligands to the glycoprotein (GP) IIb/IIIa receptors. | | Clinical Use | Eptifibatide is a cyclic heptapeptide composed of six amino acids and one mercaptopropionyl
residue. The cyclization is completed via a disulfide linkage between the cysteine and the
mercaptopropionyl moieties. The lysine-glycine-aspartate component of eptifibatide is highly specific
for the GPIIb/IIIa receptor, with low binding affinity, as indicated by the rapid dissociation constant. Because of this,
eptifibatide is a reversible, parenterally administered antagonist of platelet aggregation. | | Drug interactions | Potentially hazardous interactions with other drugs
Iloprost: increased risk of bleeding. | | Metabolism | Renal excretion accounts for approximately 50% of total
body clearance of eptifibatide; approximately 50% of the
amount cleared is excreted unchanged in the urine. |
