| abstract |
The present invention provides compounds of formula (I) and pharmaceutically acceptable salts thereof, wherein the substituents have a wide range of meanings; For example, W is -N (R22) C (Z) N (R23) -; -N (R22) S (O?) N (R23) -; wherein Z is oxygen, sulfur or NR24; n is 1; R4 and R7 are independently hydrogen, C1-8 alkyl substituted with 0-3 R11; C2-C8 alkenyl substituted with 0-3 R11; C 2-8 alkynyl substituted with 0-3 R 11; C 3-8 cycloalkyl substituted with 0-3 R 11; Bicycloalkyl of 6 to 10 carbon atoms substituted with 0 to 3 R11 groups; aryl substituted with 0-3 R12; A saturated carbocyclic group having 6 to 14 carbon atoms substituted with 0 to 3 R12 groups; a heterocyclic group substituted with 0-2 R12; wherein the heterocyclic ring consists of 5 to 10 members having at least one nitrogen atom, oxygen atom or sulfur atom. The invention also relates to pharmaceutical compositions comprising the compounds of formula (I). The pharmaceutical compositions containing the compounds of formula (I) are useful in the treatment of viral infections. ŕ |
