Protein-templated reactions enable the target-guided formation of protein ligands from reactive fragments, ideally with no background reaction. Herein, we investigate the templated formation of amides. A nucleophilic fragment that binds to the coagulation factor Xa was incubated with the protein and thirteen differentially activated dipeptides. The protein induced a non-catalytic templated reaction for the phenyl and trifluoroethyl esters; the latter was shown to be a completely background-free reaction. Starting from two fragments with millimolar affinity, a 29 nm superadditive inhibitor of factor Xa was obtained. The fragment ligation reaction was detected with high sensitivity by an enzyme activity assay and by mass spectrometry. The reaction progress and autoinhibition of the templated reaction by the formed ligation product were determined, and the structure of the protein–inhibitor complex was elucidated.

Placement of an anionic group within the oxyanion hole region of the Factor Xa catalytic site substantially enhances activity, with small flexible groups favored over bulkier ones.

, (2008/06/13)
The present invention provides compounds having a lactam ring at P3 and at P1 have a six-membered heterocyclic ring having two ring nitrogen ring atoms and the remainder of the ring atoms carbon atoms. These compounds have biological activity as active and potent inhibitors of thrombin. Their pharmaceutically acceptable salts, pharmaceutical compositions thereof and methods of using these compounds and pharmaceutical compositions comprising these compounds as therapeutic agents for treatment of disease states in mammals which are characterized by abnormal thrombosis are also described.
Non-covalent inhibitors of urokinase and blood vessel formation
-
, (2008/06/13)
Novel compounds having activity as non-covalent inhibitors of urokinase and having activity in reducing or inhibiting blood vessel formation are provided. These compounds have P1 a group having an amidino or guanidino moiety or derivative thereof. These compounds are useful in vitro for monitoring plasminogen activator levels and in vivo in treatment of conditions which are ameliorated by inhibition of or decreased activity of urokinase and in treating pathologic conditions wherein blood vessel formation is related to a pathologic condition.

, p. 743 - 748 (2007/10/03)
Evolution of P1-argininal inhibitor prototypes led to a series of non-covalent P3-7-membered lactam inhibitors 1a-w, featuring novel peptidomimetic units that probe each of the S1, S2, and S3 specificity pockets of thrombin. Rigid P1-arginine surrogates possessing a wide range of basicity (calcd pKa's~neutral-14) were surveyed. The design, synthesis, and biological activity of these targets are presented.
Dibasic inhibitors of human mast cell tryptase. Part 3: Identification of a series of potent and selective inhibitors containing the benzamidine functionality
Dener, Jeffrey M.,Rice, Kenneth D.,Newcomb, William S.,Wang, Vivian R.,Young, Wendy B.,Gangloff, Anthony R.,Kuo, Elaine Y.-L.,Cregar, Lynne,Putnam, Daun,Wong, Martin
, p. 1629 - 1633 (2007/10/03)
A survey of charged groups and linkers for a series of symmetrical and unsymmetrical dibasic inhibitors is described, leading to several classes of potent and selective inhibitors. In particular, the benzamidine functionality was identified as the most potent charged group investigated.
