The present invention provides a compound of formula I or a salt or prodrug thereof:
wherein the dotted line represents an optional chemical bond in one of the two possible positions; A represents a group of formula II:
in which R1 represents hydrogen, hydroxy, C1-6 alkyl, C2-6 alkenyl, C2-6 alkynyl, C1-6 alkoxy, benzyloxy, hydroxy(C1-6)alkyl, halogen, amino, cyano, nitro, -CONR6R7 or -S02NR6R7, in which R6 and R7 independently represent hydrogen, C1-6 alkyl, C2-6 alkenyl or C2-6 alkynyl;
R2 represents hydrogen, halogen, C1 -6 alkyl, C1 -6 alkoxy or C1-6 alkylcarbonyl;
V represents nitrogen, -CH or -C-; and
W represents oxygen, sulphur or -NR8, in which R8 represents hydrogen, C, -6 alkyl, C2-6 alkenyl or C2-6 alkynyl;
two of X, Y and Z are the same or different and each represents oxygen, sulphur or nitrogen; and the remaining group X, Y or Z is carbon, or Y is carbonyl (C = 0); and
Q is the residue of an azacyclic or azabicyclic ring system; which compounds are useful in the treatment of psychotic disorders (e.g. schizophrenia and mania); anxiety; alcohol or drug withdrawal or,dependence; pain; gastric stasis; gastric dysfunction (such as occurs with dyspepsia, peptic ulcer, reflux oesophagitis and flatulence); migraine, nausea and vomiting; moyement disorders; and presenile and senile dementia,
