title: [Hansch analysis of the inhibitory action of 3- and 4-substituted benzamidines on thrombin, plasmin and trypsin (author's transl)].
abstract: Using Hansch formalism, the suthors studied quantitatively the relationship between the structure and the inhibitory action of 3- and 4-substituted amidinophenyl derivatives on thrombin, plasmin and trypsin. It was found that the inhibitory action on all three enzymes depends in the same way from the hydrophobic and electronic properties of the substituents and from an additional term in case of substituents with X-CO-Y structure. The predictive value of the equations is satisfactory.
