Pyridine derivatives (I), their isomers and acid or base addition salts are new. Pyridine derivatives compounds of formula (I), their isomers and acid or base addition salts are new: W' = naphthyl, optionally substituted by one or more halogens, 1-6C alkyl or alkoxy, OH, CN, NO2, 1-6C trihaloalkyl, methylene dioxy, ethylene dioxy, or a group of formula (Y'); n = 1-6; Z = a bond, O, N (substituted by H, 1-6C alkyl or hydroxyalkyl), or aryl 1-6C alkyl; A = CH or N; and Q = CH or N, such that at least one of A and Q is N, and A is N when Z is a bond; M together with the C atoms to which it is attached = thieno, furo, pyrrolo or oxopyrrolo; and E with the two C atoms to which it is attached = an unsaturated, partially saturated or aromatic 5-7 membered ring system having at least one hetero atom (O, N, S), being attached to the alkylene chain either through the phenyl or through the ring, and being optionally substituted by one or more halogens, OH, CN, NO2, 1-6C alkyl or alkoxy, 1-6C trihaloalkyl, or heterocyclo 1-6C alkylene, or oxo. An Independent claim is also included for the preparation of (I). |
