A compound of formula (I) or a pharmaceutically acceptable salt thereof:
in which one of X and Y represents hydrogen and the other represents -CH₂-Z where Z is a group
in which Q represents a 3-membered divalent residue completing a 5-membered aromatic ring and comprises one or two heteroatoms selected from oxygen, nitrogen and sulphur, or three nitrogen atoms, any amino nitrogen being optionally substituted by a C₁₋₂ alkyl, cyclopropyl or propargyl group, and any ring carbon atom being optionally substituted by a group R₁; or a group
in which A₁, A₂ and A₃ complete a 5-membered aromatic ring and A₁ is oxygen or sulphur, one of A₂ and A₃ is CR₂ and the other is nitrogen or CR₃, or A₂ is oxygen or sulphur, one of A₁ and A₃ is CR₂ and the other is CR₃; and R₁, R₂ and R₃ independently selected from hydrogen, halogen, CN, OR₄, SR₄ N(R₄)₂, NHCOR₄, NHCOOCH₃, NHCOOC₂H₅, NHOR₄, NHNH₂, NO₂, COR₄, COR₅, C₂₋₄alkenyl, C₂₋₄ alkynyl, cyclopropyl or C₁₋₂ alkyl optionally substituted with OR₄, N(R₄)₂, SR₄, CO₂R₄, CON(R₄)₂ or one, two or three halogen atoms, in which each R₄ is independently hydrogen or C₁₋₂ alkyl and R₅ is OR₄, NH₂ or NHR₄; r represents an integer of 2 or 3, s represents an integer of 1 or 2 and t represents 0 or 1, with the proviso that when Y is hydrogen s is 1.
