The invention relates to tricyclic lactams of the general formula (I) ##STR1## wherein Im represents an imidazolyl group of the formula: ##STR2## and R.sup.1 represents a hydrogen atom or a group selected from C.sub.1-6 alkyl, C.sub.3-6 alkenyl, C.sub.3-10 alkynyl, C.sub.3-7 cycloalkyl, C.sub.3-7 cycloalkylC.sub.1-4 alkyl, phenyl, phenyl C.sub.1-3 alkyl, phenylmethoxymethyl, phenoxyethyl or phenoxymethyl, one of the groups represented by R.sup.2, R.sup.3 and R.sup.4 is a hydrogen atom or a C.sub.1-6 alkyl, C.sub.3-7 cycloalkyl, C.sub.3-6 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 alkhyl 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-HT.sub.3 receptors and are useful, for example, in the treatment of psychotic disorders, anxiety, and nausea and vomiting.
本发明涉及一般式(I)的三环内酰胺,其中Im代表公式的咪唑基:##STR2## R.sup.1代表氢原子或从C.sub.1-6烷基,C.sub.3-6烯基,C.sub.3-10炔基,C.sub.3-7环烷基,C.sub.3-7环烷基C.sub.1-4烷基,苯基,苯基C.sub.1-3烷基,苯基甲氧甲基,苯氧乙基或苯氧甲基中选择的基团之一,由R.sup.2,R.sup.3和R.sup.4表示的三个基团中的一个是氢原子或C.sub.1-6烷基,C.sub.3-7环烷基,C.sub.3-6烯基,苯基或苯基C.sub.1-3烷基,其余两个基团可以相同也可以不同,分别表示氢原子或C.sub.1-6烷基;n代表2或3;以及其生理上可接受的盐和溶剂合物。这些化合物是5-HT.sub.3受体的有效和选择性拮抗剂,例如,它们在治疗精神疾病,焦虑症和恶心和呕吐症方面是有用的。
