== Publication Abstract from PubMed ==
Crystal structures of DX9065a and a related bisamidino-aryl inhibitor specific for the blood-clotting factor Xa have been solved in complex with bovine beta-trypsin to a resolution of 1.9 A. Each inhibitor exhibits an extended conformation along the active site, in contrast to the compact folded structures observed for thrombin specific inhibitors. Few direct contacts (predominantly in the S1 pocket) are made between trypsin and the inhibitors. Transfer of the inhibitors to the active site of factor Xa suggests a three-site interaction: salt bridge formation at the base of the primary specificity pocket, extensive hydrophobic surface burial and a weak electrostatic interaction between the distal basic component of the inhibitor and an electronegative cavity of factor Xa formed by three backbone carbonyl oxygens. Additivity of these three interactions is the basis for the observed strong inhibition of factor Xa and provides a framework for the design of novel factor Xa inhibitors. A propionic acid group of the inhibitor would clash with the thrombin specific '60-insertion loop', thus conferring selectivity against thrombin.
