The invention relates to anti-viral agents of Formula (I) wherein: RA represents OR1, NR1R2, or R1 wherein R1 and R2 independently represent hydrogen, C1-6alkyl, aryl, heteroaryl, arylalkyl or heteroarylalkyl; or R1 and R2 together with the nitrogen atom to which they are attached form a 5 or 6 membered saturated cyclic group; RB represents C(O)R3 wherein R3 represents aryl or heteroaryl; RC represents C1-6alkyl, aryl, heteroaryl or heterocyclyl; RD represents hydrogen and RE represents hydrogen, OR4 or SR4, or RD and RE together with the carbon atom to which they are attached form a carbonyl group or a thiocarbonyl group; when RE is hydrogen, OR4 or SR4, RG and RH are both hydrogen; when RD and RE together with the carbon atom to which they are attached form a carbonyl group or a thiocarbonyl group, RG represents hydrogen and RH represents hydrogen, OR4 or SR4, or RG and RH together with the carbon atom to which they are attached form a carbonyl group or a thiocarbonyl group; R4 represents hydrogen, C1-6alkyl or aryl; when RD and RE together with the carbon atom to which they are attached form a carbonyl group or a thiocarbonyl group, and RG and RH are both hydrogen or RG and RH together with the carbon atom to which they are attached form a carbonyl group or a thiocarbonyl group, then RF represents O, S, NR5 or CR6R7, otherwise RF represents CR6R7; R5 represents hydrogen, C1-6alkyl, arylalkyl or aryl; R6 and R7 independently represent hydrogen, C1-6alkyl, arylalkyl or heteroarylalkyl; RJ represents hydrogen, C1-6alkyl, heterocyclylalkyl, arylalkyl or heteroarylalkyl; and salts, solvates and enantiomers thereof; provided that when RA is OR1 then R1 is other than tert-butyl. A process for the preparation of compounds of Formula (I) and methods of using them in HCV treatment are provided.
