Novel compounds of formula (I), processes for their preparation, and their use as pharmaceutical agents are described:
in which p represents an integer of 2 to 4; r represents an integer of 1 or 2; s represents 0 or 1; and X represents a group
in which A₁ is oxygen or sulphur, one of A₂ and A₃ is CR₁ and the other is nitrogen or CR₂, or A₂ is oxygen or sulphur, A₁ is CH and A₃ is CR₁, where R₁ and R₂ are independently selected from hydrogen and C₁₋₂ alkyl, with the proviso that when r is 2, R₁ and R₂ are hydrogen or methyl.
