A compound of general formula (I), or pharmaceutically acceptable salts, solvates or polymorphs thereof; wherein; R1 and R2, which may be the same or different, are hydrogen, C1-C6alkyl, (CH2)m(C3-C6cycloalkyl) wherein m =0, 1, 2 or 3, or R1 and R2 together with the nitrogen to which they are attached form an azetidine ring; each R3 is independently CF3, OCF3, C1-4alkylthio or C1-C4alkoxy; n is 1, 2 or 3; and R4 and R5, which may be the same or different, are: A-X, wherein A =—CH=CH— or —(CH2)p— where p is 0, 1 or 2; X is hydrogen, F, Cl, Br, I, CONR6R7,SO2NR6R7, SO2NHC(=O)R6, OH, C1-4alkoxy, NR8SO2R9, NO2, NR6R11, CN, CO2R10, CHO, SR10, S(O)R9 or SO2R10 R6, R7, R and R10 which may be the same or different, are hydrogen or C1-6alkyl optionally substituted independently by one or more R12; R9 is C1-6 alkyl optionally substituted independently by one or more R12; R11 is hydrogen, C1-6 alkyl optionally substituted independently by one or more R12, C(O)R6, CO2R9, C(O)NHR6 or SO2NR6R7; R12 is F, OH, CO2H, C3-6cycloalkyl, NH2, CONH2, C1-6alkoxy, C1-6alkoxycarbonyl or a 5- or 6-membered heterocyclic ring containing 1, 2 or 3 heteroatoms selected from N, S and O optionally substituted independently by one or more R13; or R6 and R7, together with the nitrogen to which they are attached, form a 4-, 5- or 6-membered heterocyclic ring optionally substituted independently by one or more R13; or a 5- or 6-membered heterocyclic ring containing 1, 2 or 3 heteroatoms selected from N, S and O, optionally substituted independently by one or more R13; wherein R13 is hydroxy, C1-C4alkoxy, F, C1-C6alkyl, haloalkyl, haloalkoxy, —NH2, —NH(C1-C6alkyl) or —N(C1-C6alkyl)2; wherein when R1 and R2 are methyl, R4 and R5 are hydrogen and n is 1, R3is not a —SMe group para to the ether linkage linking rings A and B.
