The present invention relates to tripeptide compounds, compositions and methods for the treatment of hepatitis C virus (HCV) infection. In particular, the present invention provides novel tripeptide analogs, pharmaceutical compositions containing such analogs and methods for using these analogs in the treatment of HCV infection.

The present invention discloses novel compounds which have HCV protease inhibitory activity as well as methods for preparing such compounds. In another embodiment, the invention discloses pharmaceutical compositions comprising such compounds as well as methods of using them to treat disorders associated with the HCV protease.

Hepatitis C virus inhibitors are disclosed having the general formula:

wherein R₁, R₂, R₃, R′, B, Y and X are described in the description. Compositions comprising the compounds and methods for using the compounds to inhibit HCV are also disclosed.

The present invention discloses novel depeptidized compounds which have HCV protease inhibitory activity as well as pharmaceutical compositions comprising such compounds and methods of using them to treat disorders associated with the HCV protease.

The invention encompasses compounds of Formula I as well as compositions and methods of using the compounds. The compounds have activity against hepatitis C virus (HCV) and are useful in treating those infected with HCV.

The present invention relates to compounds of Formula I, II, or III, or pharmaceutically acceptable salts, esters, or prodrugs thereof:

which inhibit serine protease activity, particularly the activity of hepatitis C virus (HCV) NS3-NS4A protease. Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising a compound of the present invention.

This disclosure concerns novel compounds of Formula (I) as defined in the specification and compositions comprising such novel compounds. These compounds are useful antiviral agents, especially in inhibiting the function of the NS5A protein encoded by Hepatitis C virus (HCV). Thus, the disclosure also concerns a method of treating HCV related diseases or conditions by use of these novel compounds or a composition comprising such novel compounds.

The present invention relates to macrocyclic compounds of formula (I) that are useful as inhibitors of the hepatitis C virus (HCV) NS3 protease, their synthesis, and their use for treating or preventing HCV infections.

The present invention relates to compounds of Formula I, or a pharmaceutically acceptable salt, ester, or prodrug, thereof:

which inhibit serine protease activity, particularly the activity of hepatitis C virus (HCV) NS3-NS4A protease. Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention.

A method of treating, preventing or ameliorating one or more symptoms of hepatitis C, or inhibiting cathepsin activity, in a subject is provided, in which at least one compound (e.g., a HCV protease inhibitor) is administered in one or more discrete dosages over a twenty-four hour time interval in an asymmetric pattern as to dosage amount and/or timing of dosage, wherein the at least one compound is selected from the group consisting of compounds of Formulae I-XXVI, described herein. Methods of modulating the activity of hepatitis C virus protease in a subject are also provided. Asymmetric dosing as to amount of dose and/or timing of dose permits adjustment of dosing to accommodate variations in drug metabolism and/or viral activity caused by viral cell division or a patient's circadian rhythms, thus delivering the maximum amount of dose at the time or times it is most effective.

The present invention discloses novel imidazolidinones which have HCV protease inhibitory activity as well as methods for preparing such compounds. In another embodiment, the invention discloses pharmaceutical compositions comprising such imidazolidinones as well as methods of using them to treat disorders associated with the HCV protease.

The invention encompasses compounds of formula I, including pharmaceutically acceptable salts, as well as compositions and methods of using these compounds. The compounds have activity against hepatitis C virus (HCV) and are useful in treating those infected with HCV.
