The invention relates to compounds of formula (I)
wherein Im represents a imidazolyl group of formula:
R¹ represents a hydrogen atom or a C1-6 alkyl, C3-6 alkenyl, C3-10 alkynyl, C3-7 cycloalkyl, C3-7 cycloalkylC1-4alkyl, phenyl or phenylC1-3alkyl group;
R₂ represents a hydrogen atom or a C1-6 alkyl, C3-6 alkenyl, C3-7 cycloalkyl, phenyl or phenylC1-3alkyl group;
A-B represents the group R³R⁴C-CH₂ or R³C=CH;
R³ and R⁴, which may be the same or different, each represents a hydrogen atom or a C1-6 alkyl group;
one of the groups represented by R⁵, R⁶ and R⁷ represents a hydrogen atom or a C1-6 alkyl, C3-7 cycloalkyl, C3-6 alkenyl, phenyl or phenylC1-3alkyl group, and each of the other two groups, which may be the same of different, represents a hydrogen atom or a C1-6 alkyl group;
and physiologically acceptable salts and solvates thereof.
The compounds are potent and selective antagonists of the effect of 5-HT at 5-HT₃ receptors and are useful, for example, in the treatment of psychotic disorders, anxiety, and nausea and vomiting.
