The present invention relates to compounds of Formula I or II, 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 to the subject a pharmaceutical composition comprising a compound of the present invention.

Derivatives of a new heterocyclic system, 3,3′-bi(6,8-dialkyl-2,4-dioxa-7-thia-6,8-diazabicyclo[3.3.0]-octane-7,7-dioxides), were synthesized by condensation of 1,3-dialkylsulfamides with glyoxal (as a dihydrate trimer). Their structure was investigated by spectral methods, XRD, and X-ray phase analysis of one among these compounds.
Thiadiazinones of the formula ##STR1## where R.sup.1 and R.sup.2 are identical or different and are each hydrogen, alkyl, cycloalkyl, phenyl or substituted aryl and R.sup.3 is phenyl or haloalkyl-substituted, alkyl-substituted, alkoxy-substituted or haloalkoxy-substituted or alkyl- or halo-substituted phenyl, are used in fungicides.

The present invention discloses compounds of Formula (I), or pharmaceutically acceptable salts, esters, or prodrugs thereof:
which inhibit RNA-containing virus, particularly the hepatitis C virus (HCV). 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.
