Fibrinogen receptor antagonists labeled with tritium, their use and process for their preparation.

摘要

The present invention relates to novel antagonists fibrinogen receptor labeled with a detectable atom, which has comparable affinity or HIGHEST IN FRONT OF THE RECEIVER AS 125 J INOGENO Tritium labeled claim 3 in the presence of foreign proteins eg albumin fIBRINOGEN have an affinity (KP) less than 500 nm against the receiver, their use as ligands for binding assays receiver / fibrinogen or to determine the concentration of fibrinogen receptor antagonists and process for their preparation.
