The present invention concerns 5- or 6-substituted-benzimidazole derivatives having inhibitory activity on the replication of the respiratory syncytial virus and having the formula (I) a prodrug, N-oxide, addition salt, quaternary amine, metal complex or stereochemically isomeric form thereof wherein Q is Ar2, R6, pyrrolidinyl substituted with R6, piperidinyl substituted with R6 or homopiperidinyl substituted with R6, G is a direct bond or optionally substituted C1-10alkanediyl; R1 is Arl or a monocyclic or bicyclic heterocycle; one of R 2a and R2b is cyanoCl-6alkyl, cyanoC2-6alkenyl, Ar3Cl-6alkyl, Het-C1-6alky1, N(R8aR8b)Cl-6alkyl, Ar3C2-6alkenyl, Het-C2-6alkenyl, Ar3 aminoCl-6alkyl, HetaminoCl-6alkyl, Ar3thioC1-6 alkyl, Het-thioC1-6alkyl, Ar3sulfonylC1-6 alkyl, HetsulfonylC1-6alkyl, Ar3aminocarbonyl, Het-aminocarbonyl, Ar3(CH2)naminocarbonyl, Het-(CH2)naminocarbonyl, Ar3carbonylamino, Het-carbonylamino, Ar3(CH2)ncarbonylamino, Het-(CH2)ncarbonylamino, and the other one of R2a and R2b is hydrogen; in case R2a is hydrogen, then R3 is hydrogen; in case R2b is hydrogen, the R3 is hydrogen or C1-6alkyl. It further concerns their preparation and compositions comprising them, as well as their use as a medicine.
