The present invention relates to a method for preparing a peptide having a stable, internally constrained alpha-helical, beta-sheet / beta-turn, 310-helical, or pi-helical region and a method of stabilizing an alpha-helical, beta-sheet / beta-turn, 310-helical, or pi-helical region within a peptide structure. The resulting peptides and methods of using them are also disclosed.

The present invention provides novel peptidomimetic macrocycles and methods for their preparation and use, as well as amino acid analogs and macrocycle-forming linkers, and kits useful in their production.

The invention provides 4-amino-4-oxobutanoyl peptide compounds of Formula Iand the pharmaceutically salts and hydrates thereof.The variables R1-R9, R16, R18, R19, n, M, n, M, and Z are defined herein. Certain compounds of Formula I are useful as antiviral agents. Certain 4-amino-4-oxobutanoyl peptide compounds disclosed herein are potent and / or selective inhibitors of viral replication, particularly Hepatitis C virus replication. The invention also provides pharmaceutical compositions containing one or more 4-amino-4-oxobutanoyl peptide compounds and one or more pharmaceutically acceptable carriers. Such pharmaceutical compositions may contain 4-amino-4-oxobutanoyl peptide compound as the only active agent or may contain a combination of 4-amino-4-oxobutanoyl peptide containing peptides compound and one or more other pharmaceutically active agents. The invention also provides methods for treating viral infections, including Hepatitis C infections, in mammals.
