Novel basic derivatives of benz[e]isoindol-1-ones and pyrrolo[3,4-c]quinolin-1-ones which can be represented by the general formula (I) indicated below are described:
1
in which
X is CH or N,
R is H, Cl or OR
1
in which R
1
is H or an alkyl group having from 1 to 3 carbon atoms,
Het is the 3-endotropyl group (that is, the 8-methyl-8-azadicyclo[3.2.1]oct-3-yl group) or the 3-quinuclidyl group (that is, the 1-azadicyclo[2.2.2]oct-3-yl group); these compounds have been found to be potent and selective antagonists of the 5-HT
3
serotonin-like receptor and can therefore be used, for example, as anti-emetics as well as in various pathological conditions of the central nervous system, and as antitussives.
描述了苯并吲哚-1-酮和吡咯并吲哚-3,4-c 并吲哚-1-酮的新型碱性衍生物,这些衍生物可由下面所示的通式 (I) 表示:
1
其中
X 是 CH 或 N、
R 是 H、Cl 或 OR
1
其中 R
1
是 H 或具有 1 至 3 个碳原子的烷基、
Het 是 3-endotropyl 基团(即 8-甲基-8-氮杂双环[3.2.1]辛-3-基团)或 3-quinuclidyl 基团(即 1-氮杂双环[2.2.2]辛-3-基团)。
3
5-HT 3 类血清素受体的强效选择性拮抗剂,因此可用作止吐药、中枢神经系统的各种病理状态和抗惊厥药等。
