The invention relates to ketones of the general formula (I):
wherein R¹ represents a hydrogen atom or a group selected from C₁₋₆alkyl, C₃₋₆alkenyl, C₃₋₁₀alkynyl, C₃₋₇cycloalkyl, C₃₋₇cycloalkylC₁₋₄alkyl, phenyl, phenylC₁₋₃alkyl, -CO₂R⁸, -COR⁸, -CONR⁸R⁹ or -SO₂R⁸ (wherein R⁸ and R⁹, which may be the same of different, each represents a hydrogen atom, a C₁₋₆alkyl or C₃₋₇cycloalkyl group, or a phenyl or phenylC₁₋₄alkyl group, in which the phenyl group is optionally substituted by one or more C₁₋₄alkyl, C₁₋₄alkoxy or hydroxy groups or halogen atoms, with the proviso that R⁸ does not represent a hydrogen atom when R¹ represents a group -CO₂R⁸ or -SO₂R⁸);
R² represents a hydrogen atom or a C₁₋₆alkyl, C₃₋₆alkenyl, C₃₋₇cycloalkyl, phenyl or phenylC₁₋₃alkyl group;
R³ and R⁴, which may be the same of different, each represents a hydrogen atom or a C₁₋₆alkyl group; or
R² and R³ may together represent an alkylene chain -(CH₂)n-, where n represents 1, 2 or 3;
one of the groups represented by R⁵, R⁶ and R⁷ is a hydrogen atom or a C₁₋₆alkyl, C₃₋₇cycloalkyl, C₃₋₆alkenyl, phenyl or phenylC₁₋₃alkyl group, and each of the other two groups, which may be be same or different, represents a hydrogen atom or a C₁₋₆alkyl group;
Q represents a hydrogen atom or a halogen atom or a hydroxy, C₁₋₄alkoxy, phenylC₁₋₃alkoxy or C₁₋₆alkyl group or a group -NR¹⁰R¹¹ or -CONR¹⁰R¹¹ (wherein R¹⁰ and R¹¹, which may be the same or different, each represents a hydrogen atom or a C₁₋₄alkyl or C₃₋₄alkenyl 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 compounds are potent and selective antagonists of the effect of 5-HT and 5-HT₃ receptors and are useful, for example, in the treatment of psychotic disorders, anxiety, and nausea and vomiting.
