[Synthetic inhibitors of serine proteinases. Part 25: Inhibition of trypsin, plasmin and thrombin by amides of N alpha-substituted amidinophenylalanines and 3-amidinophenyl-3-aminopropionic acids (author's transl)].
Amides of N alpha-substituted 3-amidinophenylalanine are potent inhibitors of the serine proteinases trypsin, plasmin and thrombin. They belong to the most potent inhibitors of these enzymes of the benzamidine type. In contrast, amides of 4-amidinophenylalanine possess weak inhibitory activity towards trypsin and plasmin. The cyclic amides of this group, however, are potent thrombin inhibitors. These derivatives are the first benzamidines with specific antithrombin activity. The isomeric compounds of 3-amidinophenyl-3-aminopropionic acids possess weak inhibitory effects on trypsin, plasmin and thrombin.
