zo[4,5-c]pyridines represent a novel class of compounds with activity against pestiviruses and the hepatitis C virus (HCV). Several series of analogues with modifications of the substituents in positions 2 and 5 were prepared. These efforts resulted in the discovery of several compounds with potent antiviral activity of which 2-(2,3-difluorophenyl)-5-[4-(trifluoromethyl)benzyl]-5H-imidazo[4,5-c]pyridine
A compound of formula (1) and its salts and solvates are provided for the treatment or prophylaxis of hepatitis C virus infections
Methods of making and formulating compound (

A novel class of inhibitors of the hepatitis C virus [substituted 2-(2-fluorophenyl)-5H-imidazo[4,5-c]pyridines] is described. Introduction of a fluorine in position 2 of the 2-phenyl substituent of the lead anti-pestivirus compound 1 (5-[(4-bromophenyl)methyl]-2-phenyl-5H-imidazo[4,5-c]pyridine) resulted in an analogue with selective activity against HCV in the subgenomic replicon system.

2-phenylimidazo[4,5-b]pyridines (e.g., sulmazole) or 8-phenylpurines. Furthermore, all imidazo[4,5-c]pyridine analogues we tested were orally active; in contrast, only one of the imidazo[4,5-b]pyridinederivatives, sulmazole, was significantly active. One of several highly active compounds in the [4,5-c] series was 50 (LY175326, 2-[2-methoxy-4-(methylsulfinyl)phenyl]-1H-imidazo[4,5-c]pyridine hydrochloride)
