Design and Synthesis of Potent, Non-peptide Inhibitors of HCV NS3 Protease
摘要:
Starting from a hexapeptide boronic acid lead, 3-amino bicyclic pyrazinones as novel beta-sheet dipeptide mimetics have been designed and synthesized. Side-chain manipulation of this scaffold generated a series of potent, nonpeptidic inhibitors of HCV NS3 protease. (C) 2003 Elsevier Science Ltd. All rights reserved.

(2S,4S)-2-Amino-4-(4,4-diphenylbut-1-yl)-pentane-1,5-dioic acid 1m, is a novel metabotropicglutamatereceptor (mGluR) antagonist with insignificant ionotropic affinity. It is selectiveantagonist of negatively-coupled cAMP-linked mGluRs with no effect on phosphoinositide coupled mGluRs. A series of 4-substituted glutamic acid analogues were prepared and it was found that compound 1k is tenfold more

The present invention relates generally to compounds that inhibit serine proteases. In particular it is directed to novel amino-bicyclic pyrazinone and pyridinone compounds of Formula (I):
or a stereoisomer or pharmaceutically acceptable salt form thereof, which are useful as selective inhibitors of serine protease enzymes of the coagulation cascade; for example thrombin, factor Xa, factor XIa, factor IXa, and/or factor VIIa. 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.
