摘要： The present invention concerns piperidine-amino-benzimidazoles having inhibitory activity on the replication of the respiratory syncytial virus and having the formula their prodrugs, N-oxides, addition salts, quaternary amines, metal complexes and stereochemically isomeric forms wherein Q is C1-6alkyl optionally substituted with trifluoromethyl, C3-7cycloalkyl, Ar2, hydroxy, C1-4alkoxy, C1-4alkylthio, Ar2-oxy-, Ar2-thio-, Ar2(CH2)noxy, Ar2(CH2)nthio, hydroxycarbonyl, aminocarbonyl, C1-4alkyl-carbonyl, Ar2-carbonyl, C1-4alkoxycarbonyl, Ar2(CH2)ncarbonyl, aminocarbonyloxy, C1-4alkylcarbonyloxy, Ar2-carbonyloxy, Ar2(CH2)ncarbonyloxy, C1-4alkoxy-carbonyl(CH2)noxy, mono- or di(C1-4alkyl)aminocarbonyl, mono- or di(C1-4alkyl)-aminocarbonyloxy, aminosulfonyl, mono- or di(C1-4alkyl)aminosulfonyl or a heterocycles selected from the group consisting of pyrrolidinyl, pyrrolyl, dihydropyrrolyl, imidazolyl, triazolyl, piperidinyl, homopiperidinyl, piperazinyl, morpholinyl, thiomorpholinyl, 1-oxo-thiomorpholinyl, 1,1-dioxothiomorpholinyl, pyridyl and tetrahydropyridyl, wherein each of said heterocycle may optionally be substituted with oxo or C1-6alkyl; G is a direct bond or optionally substituted C1-10alkanediyl; R1 is Ar1 or a monocyclic or bicyclic heterocycle; one of R2a and R3a is C1-6alkyl and the other one of R2a and R3a is hydrogen; in case R2a is different from hydrogen then R2b is hydrogen or C1-6alkyl, and R3b is hydrogen; in case R3a is different from hydrogen then R3b is hydrogen or C1-6alkyl, and R2b is hydrogen; t is 1, 2 or 3; Ar1 is phenyl or substituted phenyl; and Ar2 is phenyl or substituted phenyl. It further concerns their preparation and compositions comprising them, as well as their use as a medicine.
