Abstract: | Structure-activity relationships for the inhibition of thrombin and trypsin by N alpha-substituted amidinophenyl-alpha-aminoalkylcarboxylic acid amides are presented. Secondary cyclic amides of N alpha-substituted 4-amidinophenylalanine and 2-amino-5-(4-amidinophenyl)valeric acid were found to be potent and specific inhibitors of thrombin, whereas trypsin was inhibited strongly by primary amides of 2-amino-4-(4-amidinophenyl) butyric acid. For this type of inhibitor the carbon amide structure seems to play a decisive role in the enzyme-inhibitor interaction. |
