Use of proteasome inhibitors for the treatment of viral infections

摘要

Composition for treating viral infections contains, as active component, at least one proteosome inhibitor (I). ACTIVITY : Virucide; cytostatic; hepatotropic; anti-HIV; nootropic; nephrotropic. MECHANISM OF ACTION : (I) inhibit, regulate or otherwise affect activity of the ubiquitin-proteosome pathway, especially the enzymatic activity of the complete 26S proteosome complex or the free (i.e. not assembled with regulatory subunits) 20S catalytically active proteosome structure. Particularly they (ir)reversibly block the proteolytic (trypsin, chymotrypsin or postlutamyl-peptide hydrolase) activities of the proteosome, so inhibit maturation, release and replication of viruses. Particularly they inhibit release of hepatitis virions or, for retroviruses, prevent processing of the gag protein by viral proteases. (I) may also modulate expression or activity of the p53 tumor suppressor and alter phosphorylation of herpes viral nucleocapsids.
