The invention relates to tricyclic lactams of the general formula (I)
wherein Im represents an imidazolyl group of the formula:
and R¹ represents a hydrogen atom or a group selected from C₁₋₆alkyl, C₃₋₆alkenyl, C₃₋₁₀alkynyl, C₃₋₇cycloalkyl, C₃₋₇cycloalkylC₁₋₄alkyl, phenyl, phenylC₁₋₃alkyl, phenylmethoxymethyl, phenoxyethyl, phenoxymethyl, -CO₂R⁵, -COR⁵, -CONR⁵R⁶ or -SO₂R⁵ (wherein R⁵ and R⁶, which may be the same or different, each represent 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 R⁵ does not represent a hydrogen atom when R¹ represents a group -CO₂R⁵ or -SO₂R⁵);
one of the groups represented by R², R³ and R⁴ 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;
n represents 2 or 3;
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) 的三环内酰胺
其中 Im 代表式中的咪唑基团:
和 R¹ 代表氢原子或选自 C₁₋₆烷基、C₃₋₆烯基、C₃₋₁₀炔基、C₃₋₇ 环烷基、C₃₋₇ 环烷基、C₁₋₄烷基、苯基、C₁₋₃烷基、苯甲氧基甲基、苯氧基乙基、苯氧基甲基、-CO₂R⁵、-COR⁵、-CONR⁵R⁶或-SO₂R⁵(其中 R⁵ 和 R⁶可以相同或不同、各自代表氢原子、C₁₋₆烷基或 C₃₋₇环烷基或苯基或苯基 C₁₋₄ 烷基,其中苯基任选被一个或多个 C₁₋₄ 烷基取代、C₁₋₄烷氧基或羟基或卤素原子取代,但当 R¹ 代表-CO₂R⁵或-SO₂R⁵基团时,R⁵不代表氢原子;)
R²、R³和R⁴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)分别代表氢原子或 C₁₋₆烷基;
n 代表 2 或 3;
及其生理上可接受的盐和溶剂。
这些化合物是 5-HT₃ 受体上 5-HT 效应的强效选择性拮抗剂,可用于治疗精神障碍、焦虑、恶心和呕吐等疾病。
