Definitions

  • Materials having varying degrees of thromboresistance have been utilized in vascular prostheses with limited success. These materials include corroding (self-cleaning) metals, synthetic polymers such as polydimethyl siloxane. Teflon, acrylates and methacrylates such as polyethylene terphthalate, electrets, anionic copolymers, and hydrogels (for a review see Salzman et al. (1987) in Hemostasis and Thrombosis, Basic Principles and Clinical Practice (Colman et al., eds.) J. B. Lippincott Co., Phila. PA, pp. 1335-1347).
  • the synthetic material may be contacted with a solution which removes impurities therein and/or thereon prior to the activation step described above.
  • FIGURE 6 is a graphic representation of the activities of grafts including immobilized thrombomodulin or BSA;
  • Thrombogenesis inhibitors useful for these purposes include molecules which interfere with, or inhibit thrombogenesis. These include, but are not limited to, ATPase, ADPase, 5'-nucleotidase, streptokinase, urokinase, tissue plasminogen activator, thrombomodulin, anticoagulants, and platelet inhibit ' (e.g., prostacycline and aspirin) Active fragments of these thrombogenesis inhibitors may be provided by enzymatic digestion using any number of know proteolytic enzymes (e.g. trypsin, chymotrypsin) whose exact locus of cleavage along an amino acid sequence is well known in the art.
  • proteolytic enzymes e.g. trypsin, chymotrypsin
  • SPDP derivatization linkage of certain groups on the thrombogenesis inhibitor to SPDP may destroy some inhibitor activity because at least some of these groups may be required for such activity.
  • SPDP becomes somewhat selective for epsilon amino groups. The result of these conditions favor a 1:1 (mole:mole) conjugation ratio of inhibitor to SPDP covalently bound without destroying biological activity.
  • the activated material is placed into 100.0 ml of 10 mM water-soluble carbodiimide (EDC) in deionized water, pH 4.6-5.0, for 1 hour at RT with constant stirring.
  • EDC water-soluble carbodiimide

Abstract

On décrit un agent pharmacologique biocompatible soluble servant à inhiber la génération de la thrombine et la formation d'un thrombus, ainsi que des méthodes servant à produire ledit agent. L'agent ou le conjugué pharmaceutique comprend un véhicule biocompatible soluble et un inhibiteur de thrombogenèse immobilisé sur ledit véhicule par un constituant du véhicule qui lie l'inhibiteur. L'inhibiteur de thrombogenèse est un inhibiteur autre que l'hirudine, ou un analogue actif ou un fragment actif de cet inhibiteur. L'inhibiteur peut être lié au constituant du véhicule au moyen d'un réactif de liaison transversale bifonctionnel.
