title: [Synthetic inhibitors of serine proteinases. 31. The inhibition of trypsin, plasmin and thrombin by isomeric compounds of N alpha -arylsulfonylated omega-amidinophenyl-alpha-aminoalkylcarboxylic acid amides].
abstract: Isomeric compounds of N alpha-arylsulfonylated amides of omega-amidinophenyl-alpha-aminoalkylcarboxylic acids--N alpha-amidinophenylsulfonylated amides or N alpha-arylsulfonylated amidino anilides of omega-phenyl-alpha-aminoalkylcarboxylic acids, respectively--possess weak antithrombin activity as compared to the derivatives of the basic structure. Thus, the assumption is corroborated that specific enzyme-inhibitor interactions account for the high antithrombin activity of certain derivatives of omega-amidinophenyl-alpha-aminoalkylcarboxylic acids. In contrast, amidinoanilides of N alpha-substituted omega-phenyl-alpha-aminoalkylcarboxylic acids are potent inhibitors of trypsin and plasmin, their inhibitory activity approaches that of primary amides of N alpha-substituted omega-amidinophenyl-alpha-aminoalkylcarboxylic acids.
