The invention provides 4-amino-4-oxobutanoyl peptide compounds of Formula I and 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.
摘要:
The present invention relates to homo- and hetero-dimer compounds formed by a disulfide, sulfinyl thio, or olefin bond between two monomers. A method of making a homo- or hetero-dimer compound is also disclosed. The present invention also relates to monomer compounds capable of forming homo- or hetero-dimer compounds, as well as oligomers formed via linkage of one or more dimers. Also disclosed are methods of inhibiting the activity of target RNA molecules, particularly those having a secondary structure that include a stem or stem-loop formation. Dimer compounds capable of inhibiting the activity of an HIV-I RNA frameshifting stem-loop and a (CUG)n expanded repeat stem-loop are disclosed, as are methods of treating diseases associated with these target RNA molecules. The dimer compounds can also be used for selectively detecting presence of the target RNA molecule in a sample.
摘要:
Peptide-based compounds including heteroatom-containing, three-membered rings efficiently and selectively inhibit specific activities of N-terminal nucleophile (Ntn) hydrolases associated with the proteasome. The peptide-based compounds include an epoxide or aziridine, and functionalization at the N-terminus. Among other therapeutic utilities, the peptide-based compounds are expected to display anti-inflammatory properties and inhibition of cell proliferation. Oral administration of these peptide-based proteasome inhibitors is possible due to their bioavailability profiles.
摘要:
There are disclosed compounds of formula (I) that modulate the activity of inhibitors of apoptosis (IAPs), pharmaceutical compositions containing said compounds and methods of treating proliferative disorders and disorders of dysregulated apoptosis, such as cancer, utilizing the compounds of the invention.

摘要:
The present invention relates to compounds of formula (I): or a pharmaceutically acceptable salt thereof, a tautomer, a stereoisomer or a mixture of stereoisomers in any proportion, in particular a mixture of enantiomers, and particularly a racemate mixture, as well as to their process of preparation, their use in the peptide synthesis, said peptide and the use of said peptide.
摘要:
The bifunctional peptide is capable of activating collagen synthesis and inhibiting the production of matrix metallo-proteinases. The peptide has a sequence including three peptide parts A, B and C. The first peptide part A corresponds to a hexapeptide repeated at least three times, the part A being capable of bonding to a receptor elastin-binding protein in order to stimulate collagen synthesis. The second peptide part B corresponds to a tetrapeptide capable of acting as a competitive inhibitor of urokinase protease and of being cleaved by said protease. The third peptide part C corresponds to a tripeptide occupying at least one active site of the matrix metallo-proteinases in order to enable inhibition of the proteinases. The present invention further concerns a cosmetic and/or pharmaceutical composition incorporating the bifunctional peptide.
摘要:
Disclosed are compositions and methods useful for targeting tissue undergoing angiogenesis or to cells or tissue expressing αv integrins.
