Literature References: Fibrinogen receptor antagonist. Specifically inhibits fibrinogen binding to the platelet integrin GPIIb-IIIa which prevents platelet aggregation and subsequent clot formation. Synthetic, disulfide-linked cyclic heptapeptide based on
barbourin, a specific GPIIb-IIIa antagonist isolated from venom of the southeastern pigmy rattlesnake,
Sistrurus m. barbouri. Contains the Lys-Gly-Asp (KGD) amino acid sequence, a modification of the Arg-Gly-Asp (RGD) recognition site which appears to confer specificity: R. M. Scarborough
