Disclosed are protease inhibitors for coronaviruses and SARS-CoV, or picornaviruses, and the use of these protease inhibitors for preventing, reducing, ameliorating and treating a disease or condition caused by coronaviruses and SARS-CoV, or picornaviruses. Also disclosed are methods of reducing or preventing the spread of coronavirus, or picornaviruses, and preventing or reducing the replication of coronavirus, or picornaviruses, with the compounds of the present invention
The present invention relates to compounds that inhibit serine protease activity, particularly the activity of hepatitis C virus NS3-NS4A protease. As such, they act by interfering with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The invention further relates to compositions comprising these compounds either for ex vivo use or for administration to a patient suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a patient by administering a composition comprising a compound of this invention.

have disclosed a novel class of P2–P4 macrocyclicinhibitors of NS3/4A protease containing a carbamate functionality as capping group at the P3 N-terminus. Herein we report our work aimed at further depeptidizing the P3 region by replacement of the urethane function with a succinamide motif. This peptidomimetic approach has led to the discovery of novel P2–P4 macrocyclicinhibitors of HCV NS3/4A protease
The present invention pertains to a process for the preparation of an enantiomerically enriched chiral carboxylic acid derivative having the partial formula: C—C—C—COOX wherein X is a cation, comprising formation of a dehydro precursor salt having the partial formula: C═C—C—COOX by reaction of the corresponding precursor acid with an at least substantially stoichiometric amount of base, and asymmetric hydrogenation of the salt in the presence of a transition metal complex of a chiral phosphine ligand.
