  • Publication number: 20070010457
    Abstract: The present invention relates to novel classes of compounds of formula I which are caspase and TNF-alpha inhibitors. This invention also relates to pharmaceutical compositions comprising these compounds. The compounds and pharmaceutical compositions of this invention are particularly well suited for inhibiting caspase and TNF-alpha activity and consequently, can be advantageously used as agents against caspase-, interleukin-1-(“IL-1”), apoptosis-, interferon-y inducing factor-(IGIF), interferon-?-(“IFN-?”), or TNF-alpha mediated diseases, including inflammatory diseases, autoimmune diseases, destructive bone disorders, proliferative disorders, infectious diseases, and degenerative diseases. This invention also relates to processes for preparing the compounds of this invention.
