| 摘要 |
The invention relates to oligopeptide derivatives whose C-terminal amino acid is arginine which is linked to the remainder of an electroactive aniline or aminoquinoline derivative by an amide bond. The oligopeptide derivatives are split by enzymes of the class of peptide hydrolases, especially proteinases and their inhibitors, of the coagulation system, the fibrinolytic system and the complement system. These oligopeptide derivatives serve as substrates for quantitatively determining such enzymes, especially thrombin, in complex sample liquids, especially capillary blood. This determination is carried out by measuring the increase in the water-soluble amperogenic aniline or aminoquinoline compound. The oligopeptide derivatives and their salts can be produced according to usual methods in peptide chemistry.
