The present invention relates generally to compounds that inhibit serine proteases. In particular it is directed to novel heterocyclic compounds, or a stereoisomer or pharmaceutically acceptable salt, solvate, or prodrug form thereof, which are useful as selective inhibitors of serine protease enzymes of the coagulation cascade; for example thrombin, factor VIIa, factor Xa, factor XIa, factor IXa, and/or plasma kallikrein. In particular, it relates to compounds that are factor VIIa inhibitors. This invention also relates to pharmaceutical compositions comprising these compounds and methods of using the same.

or CH2NHAc) were prepared and tested as inhibitors of α- and β-glucosidases and of a β-galactosidase. A new access to 4-(2-phenylethyl)-1H-imidazoles starting from 4-phenylbutan-1-ol was elaborated. The strongest inhibitors are the 2-substituted 4-(2-phenylethyl)-1H-imidazoles 24a and 26a (RC(2): CH2OH and CHOHCH2OH) and the 2-phenylethanol 34. They inhibit the β-galactosidase from bovine liver and

Indoleamine 2,3-dioxygenase (IDO) is emerging as an important new therapeutic target for the treatment of cancer, chronic viral infections, and other diseases characterized by pathological immune suppression. With the goal of developing more potent IDO inhibitors, a systematic study of 4-phenylimidazole (4-PI) derivatives was undertaken. Computational docking experiments guided design and synthesis efforts with analogues of 4-PI. In particular, three interactions of 4-PI analogues with IDO were studied: the active site entrance, the interior of the active site, and the heme iron binding. The three most potent inhibitors (1, 17, and 18) appear to exploit interactions with C129 and S167 in the interior of the active site. All three inhibitors are approximately 10-fold more potent than 4-PI. The study represents the first example of enzyme inhibitor development with the recently reported crystal structure of IDO and offers important lessons in the search for more potent inhibitors.
