The invention relates to compounds of the general formula (I):
wherein R¹ and R² together form a C₃₋₅alkylene chain and R³ is a hydrogen atom; or
R¹ and R³ together form a C₂₋₄alkylene chain and R² is a hydrogen atom;
A-B represents the group R⁴R⁵C-CH₂ or R⁴C=CH;
R⁴ and R⁵, which may be the same or different, each represent a hydrogen atom or a C₁₋₆alkyl group; and
Im represents an imidazolyl group of formula:
wherein one of the groups represented by R⁶, R⁷ and R⁸ 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 the same or different, represents a hydrogen atom or a C₁₋₆alkyl 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.
本发明涉及通式(I)的化合物:
其中 R¹ 和 R² 共同形成 C₃₋₅烷链,R³ 为氢原子;或
R¹ 和 R³ 共同形成 C₂₋₄亚烷基链,且 R² 为氢原子;
A-B 代表基团 R⁴R⁵C-CH₂ 或 R⁴C=CH;
R⁴和R⁵可以相同或不同,各自代表氢原子或C₁₋₆烷基;以及
Im 代表式中的咪唑基团:
其中 R⁶、R⁷ 和 R⁸ 所代表的基团之一是氢原子或 C₁₋₆ 烷基、C₃-₇ 环烷基、C₃-₆ 烯基、苯基或苯基 C₁₋₃烷基,而另外两个基团(可以相同或不同)中的每一个都代表氢原子或 C₁₋₆烷基;
