Inhibition of serine proteinases by benzamidine derivatives

P Walsmann. Acta Biol Med Ger. 1977.

Abstract

Derivatives of benzamidine inhibit competitively the activity of the serine proteinases trypsin, plasmin, thrombin, and of the clotting factor Xa. The inhibitor activities (Ki-values) of various benzamidine derivatives against the several enzymes were compared. Besides parallels, deviations in the corresponding structure-activity relationships were found. From these results it is concluded that the similar enzymes exhibit certain differences in the structure of the primary and secondary binding sites.
