process has been successfully developed for the efficientdirectsynthesis of pyrrolyl or indolyl substituted 9,10-dihydrophenanthren-9-ol analogues. And 1-(phenanthren-9-yl)-1H-pyrroles can be easily obtained via dehydration of 10-(1H-pyrrol-1-yl)-9,10-dihydrophenanthren-9-ols. Furthermore, the MTT assay indicated that four compounds with indolyl substitutions showed obvious inhibitory activities against
The present invention discloses compounds of formula I or pharmaceutically acceptable salts, esters, or prodrugs thereof:
which inhibit serine protease activity, particularly the activity of hepatitis C virus (HCV) NS3-NS4A protease. Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention.
