The invention relates to compounds of formula (I) ##STR1## wherein R.sup.1 represents a hydrogen atom or a group selected from C.sub.1-10 alkyl, C.sub.3-6 alkenyl, C.sub.3-10 alkynyl, C.sub.3-7 cycloalkyl, C.sub.3-7 cycloalkyl C.sub.1-4 alkyl, phenyl, or phenyl C.sub.1-3 alkyl, --CO.sub.2 R.sup.10, --COR.sup.10, --CONR.sup.10 R.sup.11 or --SO.sub.2 R.sup.10 (wherein R.sup.10 and R.sup.11, which may be the same or different, each represents a hydrogen atom, a C.sub.1-6 alkyl or C.sub.3-7 cycloalkyl group, or a phenyl or phenylC.sub.1-4 alkyl group, in which the phenyl group is optionally substituted by one or more C.sub.1-4 alkyl, C.sub.1-4 alkoxy or hydroxy groups or halogen atoms, with the proviso that R.sup.10 does not represent a hydrogen atom when R.sup.1 represents a group --CO.sub.2 R.sup.10 or --SO.sub.2 R.sup.10); R.sub.2 represents a hydrogen atom or a C.sub.1-6 alkyl, C.sub.3-6 alkenyl, C.sub.3-7 cycloalkyl, phenyl or phenyl C.sub.1-3 alkyl group; R.sub.3 and R.sub.4, which may be the same or different, each represents a hydrogen atom or a C.sub.1-6 alkyl group; One of the groups represented by R.sup.5, R.sup.6 and R.sup.7 is a hydrogen atom or a C.sub.1-6 alkyl, C.sub.1-6 hydroxyalkyl, C.sub.3-7 cycloalkyl, C.sub.2-6 alkenyl, phenyl or phenyl C.sub.1-3 alkyl group, and each of the other two groups, which may be the same or different, represents a hydrogen atom or a C.sub.1-6 alkyl group; and Q represents a hydrogen or a halogen atom, or a hydroxy, C.sub.1-4 alkoxy, phenyl C.sub.1-3 alkoxy or C.sub.1-6 alkyl group or a group --NR.sup.8 R.sup.9 or --CONR.sup.8 R.sup.9 wherein R.sup.8 and R.sup.9, which may be the same or different, each represents a hydrogen atom or a C.sub.1-4 alkyl or C.sub.3-4 alkenyl group, or together with the nitrogen atom to which they are attached form a saturated 5 to 7 membered ring; and physiologically acceptable salts and solvates thereof. The comopounds are potent and selective antagonists of the effect of 5-HT at 5-HT.sub.3 receptors and are useful, for example, in the treatment of psychotic disorders, anxiety, and nausea and vomiting.
