ABSTRACT:
A compound of the formula I:wherein: X is CH or N; Y is O or S; Z is OH, NH2, NMeR3, NHR3; OR3or 5- or 6-membered heterocycle, having 1 to 4 heteroatoms selected from O, N and S, said heterocycle being optionally substituted with from 1 to 4 substituents; A is N, COR7or CR5, wherein R5is H, halogen, or (C1-6) alkyl and R7is H or (C1-6alkyl), with the proviso that X and A are not both N; R6is H, halogen, (C1-6alkyl) or OR7, wherein R7is H or (C1-6alkyl);R1is selected from the group consisting of 5- or 6-membered heterocycle having 1 to 4 heteroatoms selected from O, N, and S, phenyl, phenyl(C1-3)alkyl, (C2-6)alkenyl, phenyl(C2-6)alkenyl, (C3-6)cycloalkyl, (C1-6)alkyl, CF3, 9- or 10-membered heterobicycle having 1 to 4 heteroatoms selected from O, N and S, wherein said heterocycle, phenyl, phenyl(C2-6)alkenyl and phenyl(C1-3)alkyl), alkenyl, cycloalkyl, (C1-6)alkyl, and heterobicycle are all optionally substituted with from 1 to 4 substituents;R2is selected from (C1-6)alkyl, (C3-7)cycloalkyl, (C3-7)cycloalkyl(C1-3)alkyl, (C6-10)bicycloalkyl, adamantyl, phenyl, and pyridyl, all of which is optionally substituted with from 1 to 4 substituents;R3is selected from H, (C1-6)alkyl, (C3-6)cycloalkyl, (C3-6)cycloalkyl(C1-6)alkyl, (C6-10)aryl, (C6-10)aryl(C1-6)alkyl, (C2-6)alkenyl, (C3-6)cycloalkyl(C2-6)alkenyl, (C6-10)aryl(C2-6)alkenyl, N{(C1-6)alkyl}2, NHCOO(C1-6)alkyl(C6-10)aryl, NHCO(C6-10)aryl, (C1-6)alkyl-5- or 10-atom heterocycle, having 1 to 4 heteroatoms selected from O, N and S, and 5- or 10-atom heterocycle having 1 to 4 heteroatoms selected from O, N and S;wherein said alkyl, cycloalkyl, aryl, alkenyl and heterocycle are all optionally substituted with from 1 to 4 substituents; n is zero or 1; or a detectable derivative or salt thereof.The compounds of the invention may be used as inhibitors of hepatitis C virus replication.The invention further provides a method for treating or preventing hepatitis C virus infection.
