Anti-viral compounds

The present application provides a series of benzimidazole compounds of formula I: which inhibit the growth of picornaviruses, such as rhinoviruses (bovine and human), enteroviruses such as polioviruses, coxsackieviruses of the A and B groups, or echo virus, cardioviruses such as encephalomyocarditis (EMC), apthoviruses such as foot and mouth disease virus, and flaviviruses such as hepatitis C virus and bovine viral diarrhea virus. Such compounds are also useful as intermediates for preparing additional benzimidazole antiviral compounds.

Anti-viral compound

A series of benzimidazole compounds having the following general structure are provided which inhibit the growth of picornaviruses (e.g., rhinoviruses, enteroviruses, polioviruses, coxsackieviruses of the A and B groups, echo virus and Mengo virus) and flaviviruses (e.g., hepatitis C and bovine diarrheal virus). STR1 A method for inhibiting picornaviruses and flaviviruses is also provided which includes administering to a host an effective amount of the inventive benzimidazole compounds.

Antirhino/enteroviral vinylacetylene benzimidazoles: A study of their activity and oral plasma levels in mice

In an effort to find an orally bioavailable antiviral for the treatment of rhino/enteroviral infections, a series of vinylacetylene benzimidazoles (11a-o, 12, and 18a) was made. Initial studies of this class of antivirals showed that fluorine substitution on the left-hand phenyl ring in combination with the vinylacetylene moiety gave the requisite mix of physical properties to achieve good in vitro antiviral activity as well as respectable oral bioavailability in rhesus monkeys. To ascertain the generality of this finding and to broaden the scope of the structure-activity relationship (SAR), the present study concentrated on fluoro substitution of this class of molecules. The initial antiviral activity for each analogue was measured using human rhinovirus 14 (HRV-14). This served as an indicator of general antiviral activity for SAR purposes. Subsequently, the spectrum of antirhino/enteroviral activity of the more interesting analogues was evaluated through testing against a panel of seven additional rhino/enteroviruses. Broad-spectrum activity was present and consistent for all analogues tested, and it tracked closely with the antiviral activity observed against HRV-14. A simple screening protocol for oral bioavailability was established whereby compounds were administered orally to mice and plasma levels were measured. This procedure facilitated the evaluation of numerous analogues in a rapid manner. The C(max) was used as a measure of oral bioavailability to allow relative ranking of compounds. In general, fluorine substitution directly on the left-hand aromatic ring does give good oral blood levels. However, fluorine incorporation at other positions in the molecule was not as effective at maintaining either the activity or the oral plasma levels. The constructive combination of activity and oral plasma levels was maximized in three derivatives: 11a,e,g.
