== Publication Abstract from PubMed ==
 +
We have designed, synthesized, and evaluated the factor Xa inhibitory activities of p-amidinophenyl-sulfones, amines, and alcohols intended to take advantage of the polarity and hydrogen-bonding potential of the oxyanion hole region of the S1 specificity pocket. We demonstrate that placement of an anionic group within the oxyanion hole region of the catalytic site substantially enhances activity, with small flexible groups favored over bulkier ones. Ab initio pKa calculations suggest that the hydroxyl substituent frequently used for benzamidine moieties may be ionized to form an anionic group, consistent with the general trend. One nonamidine based substituent also shows promising activity.
