ABSTRACT:
The present invention concerns piperidine-amino-benzimidazoles having inhibitory activity on the replication of the respiratory syncytial virus and having the formulatheir 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, Ar2carbonyl, C1−4alkoxycarbonyl, Ar2(CH2)ncarbonyl, aminocarbonyloxy, C1−4alkylcarbonyloxy, Ar2carbonyloxy, 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; R1is Ar1or a monocyclic or bicyclic heterocycle; one of R2aand R3ais C1−6alkyl and the other one of R2aand R3ais hydrogen; in case R2ais different from hydrogen then R2bis hydrogen or C1−6alkyl, and R3bis hydrogen; in case R3ais different from hydrogen then R3bis hydrogen or C1−6alkyl, and R2bis hydrogen; t is 1, 2 or 3; Ar1is phenyl or substituted phenyl; and Ar2is phenyl or substituted phenyl. It further concerns their preparation and compositions comprising them, as well as their use as a medicine.
