Claim:
A compound of formula (I), salts, N-oxides, solvates, hydrates, racemates, enantiomers or diastereomers thereof: wherein Z 1 and Z 2 are each independently selected from C—H, C-halo, C—C 1-4 alkyl, C—C 1-4 alkylhalo, C—C 1-4 alkoxy, C—C 1-4 alkoxyhalo and N; R 1 is selected from H, C 1-6 alkyl, C 2-6 alkenyl, C 2-6 alkynyl, C 1-6 alkoxy, halo, C 1-4 alkylhalo, C 1-4 alkoxyhalo, C 3-7 cycloalkyl, C 3-7 cycloalkenyl, 5-6-membered heterocyclyl and 5-6 membered heteroaryl and wherein alkyl, alkenyl, alkynyl, alkoxy, cycloalkyl, heterocyclyl and heteroaryl in each occurrence may be optionally substituted; R 2 is H or an optional substituent; R 3 is an optionally substituted 6-membered heteroaryl group containing N in the 2-(ortho) ring position with reference to the point of attachment or R 3 is an optionally substituted 5-membered heteroaryl group containing N in the ring position adjacent to the point of attachment; R 4 is H, C 1-4 alkyl, C 2-4 alkenyl, C 2-4 alkynyl, or C 3-7 cycloalkyl; R 5 in each occurrence is independently H or optionally substituted C 1-6 alkyl; m represents an integer selected from 0, 1, 2, 3, 4, 5 and 6; and each (CH 2 ) moiety when present may be independently optionally substituted with one or two substituents; and further when m is an integer selected from 1, 2, 3, 4, 5 and 6 then one or more (CH 2 ) may be replaced with O, C═O, NH, optionally substituted NC 1-6 alkyl, S, S═O or SO 2 .
