An isomer, enantiomer, diastereoisomer, or tautomer of a compound, represented by formula (I): wherein R1 is selected from: H, haloalkyl, (C¿1-6?)alkyl, (C2-6)alkenyl, (C3-7)cycloalkyl, (C2-6)alkynyl, (C5-7)cycloalkenyl, 6 or 10-membered aryl, Het all optionally substituted; R2 is selected from (C1-6)alkyl, (C3-7)cycloalkyl, (C6-10)bicycloalkyl, 6- or 10-membered aryl, or Het all optionally substituted; B is N or CR?5¿, wherein R5 is H, halogen, haloalkyl, (C¿1-6?)alkyl, (C3-7)cycloalkyl or (C1-6)alkyl-(C3-7)cycloalkyl; X is N or CR?5¿; D is N or CR5; each of Y¿1? and Y2 is independently O or S; Z is O, N, or NR?z¿ wherein Rz is H, (C¿1-6?)alkyl, (C3-7)cycloalkyl or (C1-6)alkyl-(C3-7)cycloalkyl; R?3 and R4¿ are each independently H, (C¿1-6?)alkyl, first (C3-7)cycloalkyl, 6- or 10-membered aryl, Het (C1-6)alkyl-6- or 10-membered aryl, (C1-6)alkyl-Het; or each R?3 and R4¿ are independently covalently bonded together to form second (C¿3-7?)cycloalkyl, or heterocycle, all optionally substituted; or when Z is N, either R?3 or R4¿ are independently covalently bonded thereto to form a nitrogen-containing heterocycle; R7 is H, (C¿1-6? alkyl), (C3-7)cycloalkyl or (C1-6)alkyl-(C3-7)cycloalkyl; or R?7¿ is covalently bonded to either of R3 or R4 to form a heterocycle; A is (C¿1-6?) alkyl-CONHR?8¿ wherein R8 is-6- or 10-membered aryl, or Het; or A is a 6- or 10-membered aryl, or Het said aryl or Het being optionally substituted; or a salt or a derivative thereof; such compounds being potent inhibitors of HCV NS5B polymerase.
