-
, (2008/06/13)
The present invention relates to novel classes of compounds which are caspase inhibitors, in particular interleukin-1β converting enzyme (“ICE”) 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 activity and consequently, may be advantageously used as agents against interleukin-1-(“IL-1”), apoptosis-, interferon-γ inducing factor-(IGIF), or interferon-γ-(“IFN-γ”) mediated diseases, including inflammatory diseases, autoimmune diseases, destructive bone disorders, proliferative disorders, infectious diseases, and degenerative diseases. This invention also relates to methods for inhibiting caspase activity and decreasing IGIF production and IFN-γ production and methods for treating interleukin-1, apoptosis-, and interferon-γ-mediated diseases using the compounds and compositions of this invention. This invention also relates to methods of preparing the compounds of this invention.

Methods for the production of the monochloro derivatives of 2-(4-aminophenyl)-5(6)-aminobenzimidazole from chloronitrobenzanilides or by the condensation of 1,2,4-triaminobenzene with chloroaminobenzoic acid were investigated.It was established that the nitration of o-chlorobenzanilides takes place selectively in a mixture of acetic acid, acetic anhydride, and chloroform, while the nitration of 4(7)- or 5(6)-chlorobenzimidazoles takes place in sulfuric acid.The effect of the chlorine atoms and the nitro (amino) group on the IR and PMR spectra of the benzanilides and benzimidazoles is determined by their mutual position and by the position in relation of the amide bridge or the condensed imidazole ring.Analysis of the PMR spectra of the chlorodiaminophenylbenzimidazoles indicated that the amino group was localized at position 6 of the benzimidazole ring.
