meta‐derivative 8b inhibits factor Xa and trypsin (Ki = 10 μM). The terphenyl bisamidine 4c does not inhibit factor Xa, trypsin, thrombin, and plasmin, while 4a and 4d are almost equipotent inhibitors of theses enzymes (Ki 1–6 μM), and 4b and 4e are selective for trypsin (Ki = 0.2 and 0.3 μM; but Ki > 1 μM for factor Xa, thrombin, and plasmin). X‐ray analysis of crystals of 4b complexed with bovine trypsin revealed
