  • the invention is based on the object of finding novel compounds having valuable properties, in particular those which can be used for the production of medicaments. It has been found that the compounds of the formula I and their salts or solvates have very valuable pharmacological properties together with good tolerability.
  • GPIblX inhibitors act especially as GPIblX inhibitors, in particular inhibiting the interaction of this receptor with the ligand von Willebrand factor (vWF).
  • vWF von Willebrand factor
  • This action can be demonstrated, for example, by a method which is described by S. Meyer et al. in J. Biol. Chem. 1993, 268, 20555-20562.
  • the property as GPIblX alpha-thrombin receptor (N.J. Greco, Biochemistry 1996, 35, 915-921) can also be blocked by the compounds mentioned.
  • GPIblX as an adhesion receptor on platelets, which mediates the primary interaction of platelets with an arteriosclerotically modified vascular wall via binding to the vWF expressed there, has been described by many authors (e.g. Z.M. Ruggeri in Thromb. Hemost. 1997, 78, 611-616).
  • GPIIbllla another platelet adhesion receptor, GPIIbllla, following the GPIblX-vWF interaction, leads to platelet aggregation and thus to thrombotic vascular occlusion.
  • a GPIblX antagonist can thus prevent the start of thrombus formation and thus also release of active substances from the platelets which, for example, promote thrombus growth and have an additional trophic action on the vascular wall. This has been shown with inhibitory peptides or antibodies in various experimental models (e.g. H Yamamoto et al., Thromb. Hemost. 1998, 79, 202-210).
  • the blocking action of GPIblX inhibitors exerts its maximum effect, as described by J.J. Sixma et al. in Arteriosclerosis, Thrombosis, and Vascular Biology 1996, 16, 64-71.
  • the compounds of the formula I can be characterized as GPIblX inhibitors in whole blood.
  • the inhibition of thrombus formation of the GPIblX inhibitors can be measured by a modified Born method (Nature 1962, 4832, 927-929) using botrocetin or ristocetin as an aggregation stimulant.
  • the compounds of the formula I according to the invention can therefore be employed as pharmaceutical active compounds in human and veterinary medicine. They act as adhesion receptor antagonists, in particular as glycoprotein IblX antagonists, and are suitable for the prophylaxis and/or therapy of thrombotic disorders and sequelae deriving therefrom.
  • adhesion receptor antagonists in particular as glycoprotein IblX antagonists
  • glycoprotein IblX antagonists are suitable for the prophylaxis and/or therapy of thrombotic disorders and sequelae deriving therefrom.
  • the preferentially best action is to be expected in the case of thrombotic disorders in the arterial vascular system, but GPIblX inhibitors also have an effect in the case of thrombotic disorders in the venous vascular bed.
