The invention provides compounds of formula (I): wherein: R2 and R3 independently represent various substituents; R1 and R4 independently represent H, F, Cl, Br, Cl1-2alkyl, C1alkoxy, OH, CN, or NO2; B represents a sulfur atom or a —CH2-group; t represents 3 or 4; and A represents an optionally substituted 5- or 6-membered aromatic heterocyclic ring, or an optionally substituted bicyclic heterocyclic ring system in which at least the ring bound to the group B in Formula (I) is aromatic; or a salt thereof. Preferably, A is selected from one of the groups (i), (ii) or (iii): wherein X1 and X2 are independently N or CR8, and X3 is NR8, O or S; Y1 and Y3 are independently N or CR9, and Y2 is NR9, O or S; Z1 is NR10, O or S, and Z2 and Z3 are independently N or CR10; R8, R9, and R10 are as herein defined, and R7 is H, a halogen atom, OH, cyano, nitro, C1-4alkyl, C1-4alkoxy, C1-4alkylenedioxy, C1-4alkanoyl, or C1-4alkylsulfonyl, an optionally substituted 3-, 4-, 5- or 6-membered cycloalkyl ring, or a group of the formula (a), (b), (c) or (d) as defined by the formulas (a), (b), (c) or (d).
